Plain-English summary
A group of 19 dogs, mostly terriers around 8.6 years old, had surgery to fix their eye problems caused by lens luxation (when the lens is dislocated) or subluxation (when the lens is partially dislocated). After the surgery, which involved removing the lens and placing a new one, about 70% of the dogs kept their vision for an average of over three years. Some dogs did experience complications like glaucoma or retinal detachment, but these issues were less common than in previous studies. Overall, the surgery showed promising results for dogs with these eye conditions.

Abstract
OBJECTIVE: To evaluate the postoperative results of lensectomy and sulcus intraocular lens fixation (SIOLF) via an ab interno approach in dogs with progressive lens subluxation or early luxation. STUDY DESIGN: Retrospective study. ANIMALS STUDIED: Twenty eyes from 19 dogs presented to the Animal Eye Clinic for lens luxation or subluxation between 1999 and 2006. METHODS: Medical records were reviewed to evaluate preoperative lens position, vision status, intraocular pressure (IOP), and whether surgery was performed on an emergent or elective nature. Lensectomy and SIOLF were performed and postoperative status including vision, glaucoma, and retinal detachment was assessed. RESULTS: Average age was 8.6 years (range 4-14 years) and 55% (11/20) were terriers. Patients were followed a mean of 29.2 months (range 1-92 months) after surgery. Retinal detachment or secondary glaucoma was observed in 1 of 20 (5%) and 5 of 20 (20%) eyes, respectively, with 1 of 20 (5%) exhibiting both. Mean preoperative IOP was 16 mmHg and preoperative lens position was equally divided between luxated and subluxated lenses. Surgery was performed more frequently as an elective procedure (18/20; 90%) due to normalized IOP vs. an emergency procedure (2/20; 10%). Vision was retained in 70% (14/20) of eyes with a mean time to vision loss of 41 months in the remaining eyes due to glaucoma, retinal detachment, or retinal degeneration. CONCLUSIONS: Complications of glaucoma and retinal detachment after SIOLF in this study were less when compared with previously reported incidence rates in the literature for lensectomy alone which may reflect improved patient selection.
