Plain-English summary
A group of 17 dogs with unstable or dislocated lenses underwent surgery to have a new intraocular lens (IOL) implanted using a modified technique. Most dogs had satisfactory lens placement, and by the end of the follow-up period, 89.5% of the treated eyes were able to see. Some dogs experienced complications like increased eye pressure and corneal ulcers, but these issues were managed effectively, and the ulcers healed without problems. Overall, the new surgical method showed promising results similar to traditional techniques.

Abstract
OBJECTIVE: To describe a modified ab externo method of sulcus intraocular lens (IOL) fixation and report outcomes of eyes treated with this approach. PROCEDURES: Records of patients with lens instability or luxation that underwent a lensectomy and sulcus IOL implantation from January 2004 to December 2020 were reviewed. RESULTS: Nineteen eyes of 17 dogs had a sulcus IOL placed via a modified ab externo approach. The median follow-up time was 546 days (range 29-3387 days). Eight eyes (42.1%) developed POH. A total of six eyes (31.6%) developed glaucoma and required medical management long term to control IOP. The IOL position was satisfactory in most cases. Nine eyes developed superficial corneal ulcers within 4 weeks following surgery, all of which healed without complication. At the time of the last follow-up, 17 eyes were visual (89.5%). CONCLUSIONS: The technique described represents a potentially less technically challenging option for sulcus IOL implantation. The success rate and complications are similar to previously described approaches.
