Summary The problem of corneal operative wound healing in cataract phacoemulsification in dogs is relevant in veterinary ophthalmology. The aim of the study was to identify factors influencing the corneal healing process after cataract phacoemulsification in dogs. The study included 60 dogs of different breeds: group 1 (n = 20) - dogs receiving postoperative glucocorticosteroids (GCS) topically and systemically, group 2 (n = 20) - dogs receiving postoperative nonsteroidal anti-inflammatory drugs (NSAIDs) systemically and GCS topically, group 3 - dogs with diabetes mellitus who received in the postoperative period, NSAIDs are systemic and GCS locally. Postoperative examinations were performed on Days 1, 3, 7, 14, and 21 after surgery, with each group taking into account corneal wound tightness (per Seidel test), epithelialization (per fluorescein test), suture, infiltration, vascularization, and corneal fibrosis (per biomicroscopy). As a result of the study, it was found that in groups 1 and 2, epithelialization periods were 3-7 days, the start times of vascularization and infiltration were 7-14 days, and fibrosis - 21 days, the degree of corneal fibrosis was determined to be insignificant, and in group 3 the epithelialization time was increased to 14 days, the onset of vascularization and infiltration was 7-14 days, and fibrosis was 21 days, the degree of corneal fibrosis was severe in 25% of cases. Conclusions: Postoperative therapy regimens after cataract phacoemulsification in dogs may include systemic GCS or NSAIDs (if there are contraindications to the systemic use of GCS) and locally GCS without significant differences in the timing and quality of corneal healing, and in dogs with diabetes mellitus, with the use of systemic NSAIDs and locally GCS, epithelialization times have been increased by 7 days, and the degree of fibrosis by 25%, the possibilities of reducing these parameters have yet to be studied.
