Objective To describe the visual outcome following phacoemulsification in English Cocker Spaniels (ECS) affected by cataracts and suspected progressive retinal atrophy (PRA). Animals studied Fifty‐four client‐owned dogs. Procedures A multicenter, retrospective study was performed including ECS with suspected PRA which underwent phacoemulsification. PRA was suspected on ophthalmic examination before and after surgery, and/or after electroretinography (ERG) was performed. Visual outcome was assessed by menace response per eye at seven time periods post‐surgery (P1= 25‐90 days, P2 = 91‐180 days, P3 = 181‐364 days, P4 = 365‐549 days, P5 = 550‐729 days, P6 = 730‐1094 days, and P7 ≥ 1095 days). Descriptive statistics were performed. Generalized estimating equations were used to identify predictors associated with vision after surgery. Odds ratio and confidence intervals were reported. Significance was set at P < 0.05. Owners were invited to participate in a questionnaire. Results Phacoemulsification was performed in 85 eyes. Median age at surgery was 9.09 years (min. 2.17 years, max. 13.49 years). At all re‐examinations, up to and including P5, significantly more eyes were visual than before surgery (P ≤ 0.003). Odds for vision were significantly increased for eyes that underwent surgery. Electroretinograms were performed in 75/85 eyes that underwent surgery, demonstrating low b‐wave amplitudes. There was no significant effect of the age, gender, vision before surgery, presence of dazzle reflex, cataract stage or abnormality on gonioscopy on visual outcome. The questionnaire response rate was 48.2%. Most participants (92.5%) felt that cataract surgery led to improvement of the dog's quality of life. Conclusions English Cocker Spaniels with suspected PRA may benefit from phacoemulsification with vision up to 2 years following surgery.

Purpose: To assess outcome of phacoemulsification in cats. Methods: Records of 71 cats (82 eyes) from five referral centers were reviewed. Groups were divided by cause of cataract (congenital/juvenile [n = 32], traumatic [n = 33], and secondary to uveitis [n = 6]), and group comparisons were performed for the most common complications: postoperative ocular hypertension (POH), uveitis, corneal ulceration, synechia/dyscoria, and posterior capsular opacity (PCO) in three different time periods: immediately postoperatively, at 1-90 days, and at >90 days. Results: Median follow-up was 198 days (interquartile range 64-518 days). The overall visual success rate of the cats with a 12-month follow-up was 92.6% (25/27 eyes). POH occurred in 35/82 (42.6%) eyes. Immediately postoperatively, uveitis was the most common complication in 28/82 eyes (34.1%) followed by corneal ulceration in 22/82 eyes (26.8%). At 1-90 days, uveitis in 41/81 eyes (50.6%) remained the most common complication, followed by synechia/dyscoria in 21/81 eyes (25.9%), corneal ulceration in 16/81 eyes (19.7%), and PCO in 15/81 eyes (18.5%). At >90 days, PCO in 17/47 eyes (36.1%), followed by synechia/dyscoria in 16/47 eyes (34%), was the most common complications. The number of eyes with synechia/dyscoria in the trauma group was higher (13/33 [39.3%]) than in the congenital/juvenile group (5/31 [16.1%]) at 1-90 days (P = .039). No statistical difference was found for the other group comparisons. Three eyes in total were enucleated owing to endophthalmitis, post-traumatic ocular sarcoma, and secondary glaucoma. Conclusion: Uveitis in the short-term and PCO and synechia/dyscoria in the longterm were the most common complications following phacoemulsification in cats. K E Y W O R D S carbachol,
