OBJECTIVE: To investigate the success rate of phacoemulsification following corneal and lens laceration in dogs and cats.
PROCEDURE: Retrospective review of cats and dogs presenting with corneal and lens laceration and treated with phacoemulsification.
RESULTS: The records of 33 patients (33 eyes: six feline, 27 canine) presenting to a private referral center were reviewed. Affected dogs were younger (median 18 months) than affected cats (median 30 months). The lacerations were caused by cat scratch trauma (9/33), thorn injury (6/33), and glass shards (1/33); the cause was unknown in 17/33 cases. All cats and 85.2% of all dogs were visual at the last examination. The median follow-up was 4 and 8 months for cats and dogs, respectively. In all canine cases that developed vision loss, this occurred within the first 14 weeks postoperatively. The ultimate cause for vision loss in dogs was secondary glaucoma (4/4) and retinal detachment (1/4).
CONCLUSION: Cats have an excellent outcome and dogs a very good outcome following surgery for corneal and lens laceration. The cause of the trauma, the size of the lesion, the time interval between the ocular trauma and surgery, and the type of surgery were not found to have an influence on the outcome of patients in this study. We postulate that vision loss might develop more often in cases with complications associated with the initial corneal laceration wound.
