Set. 2006 7 3 281-285 JOURNAL OF Veterinary Science Phacoemulsification and acryl foldable intraocular lens implantation in dogs 32 cases Na-Young Vi Shin-Ae Park Man-Bok Jeong Won-Tae Kim Se-Eun Kim Je-Min Chae Kang-Moon Seo Department of Veterinary Ophthalmology College of Veterinary Medicine Seoul National University Seoul 151-742 Korea This study evaluated the surgical outcome and complications of phacoemulsification and the implantation of an acryl foldable intraocular lens IOL with a squared edge in dogs with cataracts. Thirty-two eyes from 26 dogs were examined. The mean follow up period was days ranging from 23 to 226 days. The complications after phacoemulsification were posterior capsular opacity PCO around the IOL n 11 ocular hypertension n 4 focal posterior synechia n 4 hyphema n 3 and corneal ulcer n 2 . The complications associated with the IOL were decenteration of the optic n 2 and ventral haptic displacement n 1 . Most cases of PCO were found only around the margin of the IOL and all eyes had vision during the observation period. In conclusion the implantation of an acryl-foldable lens with a squared edge at the time of phacoemulsification is an effective method for preserving the central visual field of dogs with cataract. Key words cataract dog foldable intraocular lens phacoemulsification Introduction Cataract extraction is a type of ophthalmic surgery frequently performed in veterinary medicine. Various surgical techniques have been used but phacoemulsification with the implantation of an intraocular lens IOL is currently the treatment of choice. IOL implantation improves the optics of the aphakic eye and reduces the formation of posterior capsular opacity PCO after surgery 1 15 . However IOL decenteration or luxation can cause visual alterations or increase the risk of postoperative complications 1 15 . Another potential disadvantage of IOL implantation is transient intraocular inflammation 11 In order to achieve postoperative .
