Abstract

The purpose of the study was to determine whether capsular tension ring (CTR) alone or associated with the implantation of an intraocular lens (IOL) could decrease the occurrence of posterior capsular opacification (PCO) after phacoemulsification cataract surgery in dogs. Twenty eyes of client-owned dogs with immature or mature cataracts were included in this study. In all the animals, any ophthalmic or systemic concurrent disease was excluded. The eyes were randomly selected to receive CTR alone or in association with the IOL. Laser flaremetry and clinical evaluations were conducted on post-operative days 2, 7, 14, 21 and 28. Fundus photographs were taken at the 28th and then every 30 days, up to 180 days. The results showed more inflammatory response on eyes with IOLs, although among the parameters evaluated, solely the synechiae showed significant statistical differences. Nevertheless, in both techniques almost no PCOs occurred at the end of the evaluations. These results suggest that the CTRs can be useful in the prevention of the post-operative capsular opacities, with minor complications (AU)
