Plain-English summary
A group of dogs with displaced lenses underwent surgery to remove the lenses, which can cause vision problems and secondary glaucoma (increased pressure in the eye). After the surgery, about 72% of the dogs had improved vision and normal eye pressure four to six weeks later. However, this success rate dropped over time, especially for dogs that had glaucoma before the surgery. The findings suggest that it's better to remove a lens before it causes more serious issues like glaucoma.

Abstract
Records of 48 dogs (57 eyes) that underwent intracapsular lens extraction (ICLE) of displaced lenses were reviewed. Preoperatively, 73% (19/26 eyes) of eyes with anterior luxations had secondary glaucoma compared to 43% (10/23 eyes) with subluxations and 38% (3/8 eyes) with posterior luxations. Forty-one of 57 eyes (72%) had vision and intraocular pressure (IOP) less than 30 mm Hg four to six weeks after surgery. This percentage declined to 61% (22/36 eyes) in three months and 53% (8/15 eyes) in 12 months. Eyes with glaucoma before ICLE had a lower success rate (66%) than eyes without (82%). Since secondary glaucoma was the most common cause of failure, this study suggests that removal of a subluxated lens or a posteriorly luxated lens should be recommended before the lens moves into the anterior chamber.
