Plain-English summary
A group of rabbits with cataracts that affected their vision underwent surgery to remove the cloudy lenses and replace them with artificial ones. Out of the 15 rabbits, 13 had successful phacoemulsification surgery, which helped restore their ability to follow visual cues. Most rabbits had a clear visual axis after the procedure, improving their quality of life. However, there were some complications, including one rabbit that unfortunately died during recovery. Overall, the surgery showed promising long-term results for these rabbits.

Abstract
OBJECTIVE: To describe the presentation of 15 rabbits with naturally occurring cataracts referred for phacoemulsification surgery, the procedure in 13 cases and the follow-up in 12. ANIMALS INCLUDED: Fifteen rabbits (30 eyes), nine of which stopped following visual cues in association with cataract progression. MATERIALS AND METHODS: Rabbits underwent preoperative ophthalmic and ocular ultrasound examination. RESULTS: Thirteen rabbits (22 eyes) had mature cataracts. Ten were bilateral and three unilateral. Two rabbits had an anterior chamber abscess. The cataract in one of these was incipient. One rabbit had bilateral immature cataracts. One rabbit had a subluxated lens, and one had a retinal detachment. Thirteen rabbits (22 eyes) underwent phacoemulsification. Eighteen, 13.5-mm capsular tension rings (CTRs) and seventeen, 13-mm IOLs (Acrivet, Berlin, Germany) were fitted including one 41D 60V-model, and three 49D and thirteen 58D 20S-models. Intraoperative complications included one unilateral posterior-capsular tear, one lens subluxation, and one expulsive choroidal hemorrhage. One rabbit died during anesthetic recovery. Nine cases were PCR-tested for Encephalitozoon cuniculi, and only three were positive. The median follow-up time was 12 months (4-24 months). Rabbits that were not following visual cues preoperatively did so postoperatively, and surgery resulted in a clear visual axis for the follow-up period in every case except in two, due to reasons other than the surgery. CONCLUSIONS: Phacoemulsification with CTR and IOL implantation offers good long-term results and can improve the quality of life of pet rabbits. Retinal detachment, lens luxation, expulsive choroidal hemorrhage, and anesthetic death are potential complications.
