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
