PURPOSE: This retrospective study introduces and evaluates transscleral fixation using a horizontal mattress suture of a conventional injectable acrylic intraocular lens (IOL) inserted through a 3-mm corneal incision in dogs.
MATERIALS AND METHODS: This technique was applied to four groups: lens subluxation (group SL, n = 15), anterior or posterior lens luxation (group APLL, n = 9), lens capsule tear or rupture (group LCTR, n = 7), and dislocation of the lens capsule containing an IOL (group IOLD, n = 4).
RESULTS: Patients were followed up for an average of 366.7 days (range: 94-830 days) after the surgery. Each IOL was well-centered and the overall visual success rate was 74.3% (26/35). Retinal detachment (4/35) was the most common cause of blindness, followed by glaucoma (3/35), hyphema of unknown etiology (1/35), and severe uveitis accompanied by deep corneal ulcer (1/35).
CONCLUSION: This technique enables sulcus fixation of an IOL, inserted through a 3-mm corneal incision, which is less traumatic than conventional techniques, without the need for specifically designed IOL for sulcus fixation. In this series, this technique enabled to contribute to restore emmetropic vision in dogs.
