Plain-English summary
A group of 28 dogs that had their eye lenses removed due to various issues, such as trauma or complications during surgery, received a special type of artificial lens that was fixed in place. Out of 30 treated eyes, 26 remained functional and the dogs could see well for an average of nearly 21 months after the procedure. While three dogs experienced a minor issue with the lens shifting, there were no major complications directly linked to the new lens. Unfortunately, three dogs lost their vision due to retinal detachment, and one had to have its eye removed because of a tumor regrowth.

Abstract
OBJECTIVES: To report the outcomes following the insertion of a rhexis-fixated prosthetic intraocular lens (IOL) in dogs undergoing lens removal. MATERIALS AND METHODS: The results are from 30 eyes of 28 dogs, undergoing lendectomy, in which the lens capsule could not accommodate a conventional prosthetic endo-capsular IOL. The reported cases had sustained either spontaneous or traumatic lens capsule rupture, or accidental intra-operative iatrogenic lens capsule disruption, or had required a planned, large, anterior or posterior continuous curvilinear capsulorhexis, all of which precluded insertion of a prosthetic IOL within the lens capsule. An acrylic IOL (XVET; Medicontur) was modified and positioned across the anterior and/or posterior capsulorhexes. RESULTS: Other than haptic luxation in three cases, no complications were seen that were directly attributable to the rhexis-fixated lens. Over a follow-up period from three to 76 months (mean 20.7 months) 26/30 eyes remained visual. Blindness developed in three eyes due to retinal detachment and one eye was enucleated due to regrowth of a ciliary body adenoma. CLINICAL SIGNIFICANCE: Rhexis fixation provided an alternative method to implant a prosthetic IOL when the lens capsule was unable to accommodate a conventional endo-capsular IOL.
