THE INTRACAPSULAR EXTRACTION OF DISPLACED LENSES IN DOGS - A RETROSPECTIVE STUDY OF 57 CASES (1984-1990)

Records of 48 dogs (57 eyes) that underwent intracapsular lens extract ion (ICLE) of displaced lenses were reviewed. Preoperatively, 73% (19/ 26 eyes) of eyes with anterior luxations had secondary glaucoma compar ed to 43% (10/23 eyes) with subluxations and 38% (3/8 eyes) with poste rior luxations. Forty-one of 57 eyes (72%) had vision and intraocular pressure (IOP) less than 30 mm Hg four to six weeks after surgery. Thi s percentage declined to 61% (22/36 eyes) in three months and 53% (8/1 5 eyes) in 12 months. Eyes with glaucoma before ICLE had a fewer succe ss rate (66%) than eyes without (82%). Since secondary glaucoma was th e most common cause of failure, this study suggests that removal of a subluxated lens or a posteriorly luxated lens should be recommended be fore the lens moves into the anterior chamber.
