Visual Performance of Hydrophilic and Hydrophobic Multifocal Intraocular Lens (IOL) Implantation After Endophacoemulsification in Diabetic and Nondiabetic Cataractous Dogs
Phacoemulsification lens extraction and artificial intraocular lens (IOL) implantation offer a favorable success rate and is considered as the most appropriate technique for the treatment of cataract. Endophacoemulsification is a more refined method of phacoemulsification.
- To study the preoperative, intraoperative and postoperative variables.
- To compare the incidence of posterior capsular opacification (PCO).
- To select suitable IOL specific to diabetic or nondiabetic dogs.
A period of 24 months from March 2013 to February 2015 at the Small Animal Ophthalmology unit of the Madras Veterinary College Teaching Hospital, Chennai, India were screened for the incidence and stage of cataract. A total of 24 cases were included in the study. The cases were divided into 2 groups, group I and group II of 12 each and each group was again subdivided into subgroup A (nondiabetic) and subgroup B (diabetic) consisting of 6 dogs each.
Highest incidence was recorded in Spitz (34%). Gender wise, males had more incidence (58.49%) compared to the female dogs. The age group of 6 to 10 years had the highest incidence of 40.25 per cent. An improved grade scores in dogs implanted with multifocal hydrophobic IOLs were seen.
From the study it could be concluded that the lower PCO rates were observed in hydrophobic acrylic IOLs when compared with the hydrophilic acrylic IOLs. Nondiabetic and diabetic dogs with multifocal hydrophobic IOLs had better improvement when compared with multifocal hydrophilic lenses, due to fewer complications in the acute postoperative period (80 days).
