Ability to drive after surgery for retinal detachment

Background: After vitreoretinal surgery the patient is at least temporarily unable to drive. Buckling procedures may cause refractive changes, reduced motility or impaired binocular vision. We examined the ability of these patients to drive a car according to German law after retinal surgery. Patients and methods: The frequency and extent of changes interfering with driving ability were examined in 112 unselected patients 3.5 years (2–5 years) after successful buckling procedures. We used half-round buckling elements of 3–11 mm diameter or encircling bands (2–3 mm). We examined visual acuity, frequency of permanent diplopia and field of normal binocular vision. Driving ability was considered as impaired, when visual acuity was below 0.4 in the better eye or 0.2 in the worse eye, or when diplopia occurred within a gazing field of 20 ° of diameter. Results: Eighteen of 112 (16 %) patients reported diplopia within the first 3 months, so they were temporarily unable to drive. Two to five years later 14 of 112 patients did not have sufficient visual acuity according to the German requirements. Another 2 patients had an impaired binocular vision, resulting in driving disability. Conclusion: Driving ability may be temporarily restricted by double vision in 15 % of patients after successful buckling for retinal detachment. Permanent driving ability is mainly impaired by macular involvement in retinal detachment. The type of buckling procedure is of minor importance.      

Potential of the water jet in cataract surgery

Summary Though cataract surgery is highly developed today, there are still problems such as endothelial cell loss after surgery and the occurrence of aftercataract. To reduce these complications we looked for techniques with a high degree of safety and precision. We found the water jet, an instrument already well established in liver surgery. We tested the possibility of improving the results of cataract surgery using the water jet method. Methods: We performed cataract surgery – phacoemulsifikation and polishing of the capsule – on freshly enucleated porcine bulbs using water jet and by conventional procedures. By scanning electron microscope examination we compared the results. Additionally we emulsified human lens nuclei obtained by extracapsular cataract extraction using the water jet. Results: The epithelial cells and lens fragments on the capsule were considerably reduced after the water jet procedure. Conclusion: The results show the possibility of improvement of cataract surgery by using the water jet. Further studies are necessary to adapt this technique to routine surgery in humans.      

Contact lens intolerance in infantile aphakia – indication for intraocular lenses?

Summary Due to the low rate of complications, lentectomy and contact lens fitting is the standard treatment for congenital cataract. However, contact lens fitting is not possible in all children. The authors report the main reasons for discontinuation of contact lenses in their patients. Method: In 134 consecutive lentectomies of 90 children, the underlying eye diseases and general diseases, the age at operation, compliance of parents and children, and social background were analyzed. Results: Twenty of the 90 children had to discontinue contact lens wearing. Twelve of these children were operated on one eye and 8 on both eyes. Only 2 children showed signs of contact lens complications. In 2 children treatment was stopped because of the poor visual prognosis and in 10 children the parents discontinued contact lens treatment because of a severe handicap of the child (n = 2) or due to misunderstanding and parental noncompliance (n = 8). Six children refused contact lenses without obvious reasons. Among the latter, children 2–4 years of age were at the greatest risk. Children with additional systemic abnormalities frequently developed contact lens intolerance. Conclusion: In children with systemic abnormalities and in the case of parental communication and compliance problems, discontinuation of contact lenses has to be expected in up to 30 % of cases. In these children and in children who object to contact lenses at the age of 2–4 years, intraocular lens implantation should be considered, especially in unilateral cataract, if successful contact lens treatment is not achievable within 8–12 weeks.      

Cataract surgery at the Virchow Clinic in Berlin. Review of the last 16 years

Purpose: The aim was to compare the different techniques of cataract surgery regarding early postoperative astigmatism and visual acuity. Patients and methods: The data of three groups of patients (100 eyes) were analyzed retrospectively (1980–1982; 1987–1990; 1991–1993). Three different techniques of cataract surgery were used. Included in the prospective study were the data for 285 eyes, which underwent phacoemulsification, self-sealing incision and controlled induction of astigmatism. Results: In the time period retrospectively investigated, we found that because of the advancements in operation methods, there was a reduction in the amount of surgically induced astigmatism. From 1980 to 1995 there was a clear increase in the number of patients with early low-grade postoperative astigmatism < 1 D (1980–1982: 6 %, 1987–1990: 19 %, 1991–1993: 64 %, 1994–1995: 84 %). There was an improvement in postoperative vision (with correction > 0.5) of 16 % in 1980–1982 to 45 % from 1987 to 1990, 58 % from 1991 to 1993, and to 76 % in 1994–1995. Conclusions: Surgically induced astigmatism, which was considered to be a sign of unwanted increased postoperative astigmatism, was reduced from 1980 to 1993. Through controlled induction of astigmatism it was possible to compensate for preoperative astigmatism in the prospective group. Improved surgical techniques led to improvements in early postoperative visual acuity.      

Pseudophakia in children with juvenile arthritis

Background: Cataract secondary to juvenile rheumatoid arthritis is a severe, vision-threatening complication in early childhood. Intraocular lens implantation is controversial. The follow-up of four pseudophakic eyes of three patients and their perioperative therapeutic regimen were retrospectively analyzed. Early and late postoperative complications are reported. Patients and methods: Both girls had lens aspiration and posterior lens implantation at the ages of 6 and 12 years, the boy at the age of 10 and 14 years. All patients had relapsing anterior uveitis. The follow-up time was 3 years (1–6 years). One girl was diagnosed with sarcoidosis, causing juvenile arthritis. Both girls had perioperative methothrexate and prednisolone therapy. The boy had azathioprine therapy at the time of his first cataract surgery; later he had no systemic therapy. Both girls' intraocular lenses were implanted at different eye hospitals. Results: Both girls had severe inflammatory reactions after surgery. At the hospitals both eyes had surgical revision for iris capture. In one case this was combined with exchanging the intraocular lens. Iris capture persisted for this eye and later vitrectomy with silicone oil filling was necessary to delay phthisis, resulting in amaurosis. For two pseudophakic eyes vitrectomy was necessary later because of severe vitreous opacities, but visual acuity was severely diminished by chronic cystoid macular edema and epiretinal membranes. The boy developed in his second eye intermittent iris bombata and persistent secondary glaucoma, visual acuity was stabilized at 0.5. Conclusions: Secondary cataract due to juvenile rheumatoid arthritis or sarcoidosis is a difficult situation for phacoemulsification with intraocular lens implantation in children. For severe inflammatory complications intense local and systemic anti-inflammatory therapy is mandatory. Visual prognosis is reduced for the uveitic posterior segment and glaucoma complications. IOL implantation can be recommended for only a very few patients.      

Retroequatorial myopexy combined with bimedial recession for near-distance disparity esotropia

Purpose: In cases of esotropia combined with a high AC/A ratio, partly accommodative convergence excess or with nonaccommodative convergence excess, two methods of surgical therapy are possible: recession of the medial recti (Parks) and retroequatorial myopexy (Cüppers). Our aim was to answer the question whether retroequatorial myopexy alone and in combination with bimedial recession are appropriate methods of reducing the strabismic angle at near and distant fixation to values under 10 PD and near-distance disparity to less than 10 PD to form the basis for single binocular vision without bifocals. Patients and methods: Eighty-three patients, aged 2–14 years (39 boys and 44 girls), were included in the study: 37 children (group A) with early-onset near-distance esotropia of 14–48 PD for distance and 26–65 PD for near objects and 46 children (group B) with acquired near-distance esotropia of 8–45 PD for distance and 26–70 PD for near objects. Inclusion criteria were a near-distanced disparity of at least 10 PD (range 10–33 PD), a follow-up of at least 3 months (median 5 months, range 3–69 months), retinoscopy in cycloplegia and full refractive correction. The amount of conventional surgery was chiefly based on the distance angle of esotropia. The myopexy was placed 12, 13 and 14 mm behind the insertion of the medial rectus. Results: In 73 of 83 patients (88 %) we were able to reduce the strabismic angle for distance and near fixation to less than 10 PD and in 73 cases even under 5 PD. In 77 of 83 patients (93 %) the near-distance disparity was reduced to less than 10 PD and in 72 patients (87 %) even under 5 PD. Postoperatively, 9 children had bifocals, but 3 of them have meanwhile discarded them. Two cases were slightly ocvercorrected and 1 case undercorrected. Seventy children (84 %) attained grade of binocularity. Conclusion: Retroequatorial myopexy (fadenoperation) alone and combined with bimedial recession is an effective procedure in treating esotropia with abnormal near-distance disparity.      

Surgery of Marfan-associated and idiopathic lens subluxations

Background: The ideal and safe surgical method for Marfan-associated or idiopathic lens subluxations is still a matter of debate. Patients and methods: Between 1990 and 1995, 23 eyes were operated for lens subluxations, mainly because of decreased visual acuity, but also because of conservatively uncontrolled secondary glaucoma. Marfan patients were 27.0 (5–62) years old at surgery; patients with idiopathic lens subluxations were 38.5 (11–63) years old. Surgical procedure depended on patient age and anatomical conditions. Results: All patients achieved an increase in visual acuity. Amblyopia existed in six patients. All problems due to glaucoma were controlled postoperatively. Our greatest concern was rhegmatogenous retinal detachment. It occurred in only one eye of a non-Marfan patient. Conclusion: The prognosis for lens surgery in Marfan-associated and idiopathic lens subluxations is good. The implantation of a posterior chamber lens provides a good and secure means of optical rehabilitation. Our preferred primary transscleral suture technique guarantees high security and stability of position. Previously feared surgical risks have been reduced by modern surgical procedures.      

Interocular inhibition in strabismus

Summary Many patients with acquired strabismus do not suffer from diplopia and confusion after an individually and age-dependent interval. They inhibit the image of the deviated eye by binocular rilvary and particularly by the physiological ability to disregard visually disturbing stimuli. In strabismus with early onset, binocular rivalry is also demonstrable, even for stimuli that do not normally lead to suppression. On the basis of anomalous retinal correspondence, this rivalry occurs between retinal points onto which the same object projects. The retinal area with the lesser eccentricity receives the dominance. The fovea of the deviated eye is therefore not suppressed. In small-angle strabismus with smaller functional differences between anomalous corresponding retinal points anomalous fusion and even stereopsis can be possible as long as strong suprathreshold stimuli are presented. Strabismic amblyopia as a consequence of interfoveal suppression can only develop before anomalous retinal correspondence dominates in the strabismic child.      

Reduced pathologic retinal findings after portosystemic shunting procedure in cirrhotic patients

Background: In patients with advanced cirrhosis and portal hypertension a portosystemic shunting procedure is often necessary. This induces haemodynamic changes in the systemic circulation. The aim of this study was to find out whether there were changes in the retinal perfusion as well. Methods and patients: 17 patients with mainly ethyl-toxic cirrhosis (13 male, 4 female; mean age 54 years, range 34–72 years) underwent ophthalmologic examination before and 3 months after TIPS (transjugular intrahepatic portosystemic stent shunt). Results: Before TIPS there were pathological findings in 11 patients: In five cases cotton-wool spots, in three cases discrete vessel abnormalities, in two cases small intraretinal haemorrhages and in one case papilloedema. In all cases these pathological findings were similar in both eyes. Three months after TIPS all these changes had completely disappeared or were at least considerably declining. Conclusions: The pathological findings in patients with advanced cirrhosis were interpreted as signs of reduced retinal perfusion. After a portosystemic shunting procedure signs of recovery were seen.      

Strabismus surgery in pseudophakic patients

PURPOSE: To analyze the results of strabismus surgery after previous cataract extraction with primary or secondary IOL implantation and to determine predicting factors of squint. MATERIAL AND METHODS: Eight patients with squint deviation after cataract surgery with primary or secondary IOL implantation were enrolled into this study. Each patient had complete ophthalmologic and orthoptic examination. Patients were divided into two groups. Group I consisted of 5 patients with secondary IOL implantation after traumatic cataract surgery, and group II consisted of 3 patients without ocular trauma, with primary IOL implantation. Five patients from both of groups had diplopia after IOL implantation. RESULTS: Strabismus surgery was performed in all cases. Surgery was combined with preoperative botuline toxin injections and Fresnel prism correction. Two patients were treated with adjustable suture technique. Treatment was successful in all cases. Five patients had no diplopia in primary position, two of them had occasional diplopia in secondary positions, while 3 patients with pour visual acuity achieved only esthetic effect. CONCLUSIONS: 1. Strabismus surgery in patients with pseudophakia is a complicated procedure which can optimize visual alignment, improve binocular vision and reduce diplopia. 2. Patients with diplopia or squint after IOL implantation ought to be informed about the possibility of strabismus surgery, both for diplopia and esthetic effect.     

Pre- and postoperative SLO fundus-controlled perimetric results of surgical removal of subfoveal choroidal neovascularization in AMD

Summary The follow-up of central scotomas and fixation – next to visual acuity – are important parameters for the evaluation of new therapies in AMD. Patients and methods: Twenty-three patients (age 67 to 91 years) with subfoveal CNV had SLO fundus-controlled perimetry before and 6–8 weeks after surgical removal of the CNV. The size and location of deep (0 dB) and relative (12 dB) scotomas were measured. Stability and location of fixation were analyzed. Results: Fifty-six percent of patients gained (10 % lost) more than 2 lines of VA; 52 % of deep scotomas decreased in size (26 % increased). No relative scotoma increased, but 63 % decreased, some remarkably. Most scotomas had steeper borders postoperatively. Five of 7 patients were able to fixate again. Fixation moved slightly more peripheral in 4 patients and was otherwise unchanged. None of 7 patients whose fixation was close to their fovea preoperatively lost that fixation. Conclusion: Subfoveal surgery may stabilize the course of subfoveal CNV in AMD at 6 weeks follow-up. In some patients the major benefit can be a reduction of relative scotoma due to reattachment of the retina. As the location of fixation changes little with surgery and is typically located within the area of relative scotoma, visual function can improve.      

Strabismus and diplopia as complications after cataract surgery with IOL implantation Strabismus und Diplopie als Komplikation

In our Department of Orthoptics we have seen an increasing number of patients suffering from diplopia after cataract surgery with IOL implantation. Between 1993 and 1997 the total number of patients with this problem was 24 (2.7 % of all patients, mean age 71 years, age range 38–88). We addressed the question of whether there is a common pattern of motility dysfunction.     

Phototherapeutic keratoectomy (PTK) after keratoconjunctivitis epidemica

Background: Persistent and recurrent nummuli after epidemic keratokonjunktivitis (EKC) often lead to reduced visual acuity and increased glare. In spite of long-term topical steroid therapy nummuli often recur. We tried to treat persistent nummuli with phototherapeutic keratectomy (PTK). Patients: PTK with an excimer laser (193 nm) was performed in 13 eyes of 9 patients with nummuli. The nummuli were observed over 3–72 months (mean: 36 months). Preoperatively, the visual acuity was 0.1–0.9 (mean: 0.39 ± 0.22) and the brightness acuity test (BAT) was 0.05–0.5 (mean: 0.25 ± 0.15). Prior to PTK all eyes had been treated with local steroids several times for recurrent nummuli. Results: During the follow-up from 15 to 56 months (mean: 33 ± 11.5 ms), 11 eyes had an increase in visual acuity: 0.3–1.0 (mean: 0.63 ± 0.26). The reduction of glare was especially beneficial for the patients: 0.3–0,9 (mean: 0.55 ± 0.21). One patient had a recurrence of nummuli in both eyes 6 weeks after PTK. The subjective-induced spheric refractive change was − 2.5 D to + 2.0 D. The astigmatic error changed between − 2.0 D to + 1.5 D. Conclusion: PTK seems to be an effective method of treating persistent, recurrent nummuli after EKC. The low rate of recurrence of nummuli after PTK is remarkable.      

Prevalence of diplopia related to cataract surgery among cases of diplopia

PURPOSE: To evaluate the prevalence of diplopia in Greece after cataract surgery among diplopia cases. METHODS: The authors retrospectively reviewed the medical records of 571 patients with diplopia over an 8-year period in order to evaluate the prevalence of diplopia related to cataract surgery. The surgical and anesthetic records were also reviewed. All patients had full orthoptic assessment including prisms with cover test in all gaze positions. The chi-square and cross-tabulation statistical tests were used for statistical analysis. RESULTS: Thirty-nine cases (6.8%) were having persistent diplopia related to cataract surgery. Type of anesthesia was peribulbar. Hyaluronidase was not used. Thirteen patients were men and 26 were women. Left eyes were involved in 22 cases (56.4%), right in 17 cases (43.6%). Mean age was 72.5 years. Patients were divided into four groups. Group 1 consisted of 29 patients related to surgical trauma due to anesthesia. Group 2 consisted of 7 patients related to pre-existing disorders. Group 3 consisted of 2 patients related to aniseikonia or anisometropia. Group 4 with 1 patient related to macular pathology. Vertical diplopia was mostly noted (28 cases). Twenty-nine patients were corrected with prisms, 9 needed strabismus surgery, and 1 needed both surgery and prisms. CONCLUSIONS: Cataract surgery is not a common cause of persistent diplopia. However, this report highlights that prevalence of diplopia related to cataract is high among cases of diplopia in general, with diplopia being mostly vertical (p=0.001), affecting females (p=0.006), and being more common in left eyes, although results did not reach statistical significance (p=0.133).     

Therapy-resistant unilateral chronic blepharokeratoconjunctivitis as the main finding in autoaggression syndrome. Clinicohistopathological findings

Summary Autoaggressive syndromes as causes of diseases underlying chronic blepharitis and keratoconjunctivitis that are refractory to treatment are often difficult to recognize. Patients: Three female patients (age 21, 25, 41 years) and one male patient (age 42 years) had suffered from a right-(4 × ) or left-(1 × ) handed treatment-refractory blepharokeratoconjunctivitis for 1, 2 ,11 and 30 months prior to admission. In each case more than 5 ophthalmologists and 2–6 eye hospitals had been consulted, and extraocular surgery had been performed 1–4 times. Results: Patients presented with a visual acuity of 0.3 p (1 × ), 0.1 (1 × ), FC (1 × ), HM (1 × ). In three patients contact eczema of the facial skin and lids and a corneal pannus were observed; in two patients we saw purulent pseudomembranous and in two patients chronic cicatrizing keratoconjunctivitis. Conjunctival smears grew P. aeruginosa, and S. aureus; impression cytology showed infiltration with neutrophils and epithelial keratinization; histopathology indicated chronic inflammatory, partly purulent subepithelial and stromal conjunctival infiltrate with hyper- and parakeratosis fibrous strands and epithelial cell loss; the lower lids showed parakeratosis, focal necrosis, intercellular edema and a lymphohistiocytic round-cell infiltrate. Furthermore, multiple allergies to antibiotics and preservatives (4 × ), lacerations of the arms and legs (2 × ) and an irritative-toxic dermatitis (1 × ) were substantiated. In the patients who agreed to a psychiatric consultation, somatized-agitated longing for care combined with a dependent and infantile personality (1 × ) and reactive depression (2 × ) were verified. Conclusions: In patients suffering from treatment-refractory unilateral chronic blepharokeratoconjunctivitis correlated with the hand, one must take into consideration the fact that other factors may be involved: possible exacerbation prior to examinations; multiple inpatient diagnostic and surgical procedures in different locations; histopathological mixed inflammatory patterns; and psychiatric syndromes.      

Congenital and Developmental Cataracts: Focus on Strabismus Outcomes at Long-Term Follow-Up

Purpose: To evaluate the incidence of strabismus in congenital and developmental cataract surgery in patients with a follow-up longer than five years. Methods: All patients with congenital and developmental cataracts observed from 1996 to 2013 with a follow-up longer than five years were retrospectively included. Results: We included 117 patients (58 females and 59 males, mean age 0.62±0.3 years, 160 eyes) with congenital cataracts and 73 patients (32 females and 41 males, mean age 6.63±0.7 years, 121 eyes) with developmental cataracts. Before cataract surgery, strabismus was present in 88 patients with congenital cataracts (75.2%) and in 30 patients with developmental cataracts (41.1%) (p=0.01). After a follow-up of 9.26±1.3 years (range, 5–14 years), a significantly greater incidence of strabismus was observed after surgery only in patients with unilateral congenital cataracts who underwent cataract removal and primary IOL implantation (p=0.02). Distance BCVA and near BCVA were better after surgery for developmental cataracts (p<0.05). Presence of binocular vision was more frequent after surgery for developmental cataracts (p=0.001). Conclusion: Incidence of strabismus and postsurgical onset of strabismus at long-term follow-up was greater in patients with congenital cataracts.     

Preliminary report: Fixation behavior and reading strategies in dyslexic and normally reading children as assessed by the scanning laser ophthalmoscope

Abstract

Introduction: One goal of pre-operative sensorimotor testing is to determine fusion potential. Potential for recovery of binocularity following surgical repair of strabismus is inversely correlated to duration of misalignment. The purpose of this study was to determine binocular vision outcomes in long-standing, large-angle, constant exotropia, when the pre-operative sensorimotor exam predicts poor sensory outcome.

Methods: Patients with constant exotropia >35Δ, present for ≥20 years, and scheduled to undergo strabismus surgery were recruited. Subjects were sorted into 3 groups based on pre-operative sensorimotor results. Group A had evidence of fusion pre-operatively, Group B demonstrated suppression on all tests, and Group C demonstrated paradoxical diplopia on at least one test.

Results: Twenty patients were included: 11 in Group A, 5 in Group B, and 4 in Group C. Binocular vision was regained following surgery by 100% in Group A, 80% in Group B, and 50% in group C.

Conclusion: Surgical realignment leads to improvements in binocular vision in most patients, even in the case of very long-standing, large, constant deviations. The presence of paradoxical diplopia or dense suppression pre-operatively does not preclude a good sensory outcome.     

Early and delayed consecutive exotropia following a medial rectus faden operation

Summary The main advantage of the bilateral medial rectus faden operation (posterior fixation suture) for the treatment of essential infantile esotropia is the low occurrence of delayed consecutive exotropia. Nevertheless, this unwanted complication also occasionally occurs after a faden operation. Patients: All patients operated on between 1988 and 1997 for subsequent exotropia following bimedial faden operations without recessions were included in this study. Surgery for exotropia consisted of uni- or bilateral lateral rectus muscle recession or in removing the faden with or without resection. Results: Within the 10 years examined a bimedial faden operation (without recession) was performed in 1569 patients. In the same period 49 patients were operated on for a consecutive exotropia after a faden operation. Thirty-four (69.4 %) of the consecutive exotrope patients showed exodeviation immediately following the surgery (group I). Fifteen (30.6 %) patients developed manifest exotropia 1–53 months later (group II). The hyperopia at the time of the first operation was 2.5 D in group I and 2.3 D in group II (spherical equivalent). A bimedial faden operation with simultaneous shortening of the anterior muscle segment was performed in four patients in group II and only in two patients in group I. Cerebral palsy was evident in three patients in group II and also so in three patients in group I. Conclusion: Exotropia appearing immediately after surgery is most likely the result of an individually overdosed operation. This conclusion is not sufficient for delayed exotropia. Motor and sensory instabilities, such as those in patients needing a faden operation with simultaneous shortening of the anterior muscle segment for the treatment of convergence excess with no deviation at far or in patients showing cerebral palsy, seem to increase the risk of delayed consecutive exotropia. The mean interval between the initial surgery and the manifestation of consecutive exotropia is lower than is known from other surgical procedures.      

Using a botuline toxin diagnostic test in a case of bilateral stilling--Türk--Duane (STD) syndrome found during preparation for cataract surgery

PURPOSE: The presentation of complex procedures in preoperative diagnosis, allowing the evaluation of reaction of a patient with bilateral STD syndrome, to a potential change in the long-lasting ocular motility disturbances and corrective head position. MATERIAL AND METHODS: The botuline toxin was injected into the medial rectus muscle of the eye with greater motility disturbance in convergent strabismus. It was discovered during preparation for cataract surgery in a 45 years old female with STD Syndrome I type. Due to reduced visual acuity the diagnosis of binocular vision were performed after bilateral cataract surgery. We were afraid that the fixed sensory status of the patient would change, and therefore we performed botuline injections. Strabismus angle, ocular motility and diplopia were assessed and compared. RESULTS: The reduction of strabismus angle was achieved with no diplopia. The patient no longer needed the corrective head position, with binocular vision present while looking straight ahead. Also, a slight improvement was obtained in the abduction motility of the eye to which botuline toxin was injected. CONCLUSION: Preoperative diagnostic botuline toxin injection into the rectus medial muscle of the eye with greater motility disturbance, gives an effect of strabismus reduction. This allows for further decisions of whether, and what type of surgical treatment should be performed.     

Binocular diplopia after cataract operation

BACKGROUND: The development of binocular diplopia after cataract surgery is a serious complication. The present retrospective study aims to improve our understanding of this phenomenon and its prevention. PATIENTS AND METHODS: A series of 11 patients with binocular diplopia after cataract surgery under local retrobulbar anaesthesia is presented. The patients were followed over a period ranging from 1 to 31 months. RESULTS: Three types of disorders were found: muscular or nervous injuries (7/11), decompensated latent heterophorias (2/11), and disclosed previous strabismus with abnormal retinal correspondence (2/11). The treatment was surgical for 3 patients, and a prismatic correction was prescribed for 6 patients. Spontaneous recovery was seen in 5 patients. CONCLUSION: Fortunately, binocular diplopia after cataract surgery is a rare complication, with multiple aetiopathologies. Muscular injuries, related to the anaesthesic technique, are the most frequent disorders responsible for diplopia and often require strabismus surgery.
