Abstract

The history of the intraocular lens implantation surgery in our country is very short. Hence there is no sufficient accumulation of experience and knowledge about it. In the view of its superiority and effectiveness in the optical correction of an aphasic eye we should make the intraocular lens implantation more popular quite soon now.
In order to experience the intraocular lens implantation surgery and evaluate its complications histopathologically the authors implanted the intraocular lens in 20 rabbits. 15 rabbits of them had been observed. The Choyce VIII anterior chamber lens was implanted into 12 eyes of 6 rabbits of which lens was extracted extracapsularly in 3 eyes and intra capsularly in 9 eyes. The Binkhorst two-loop lens was introduced into 12 eyes of 6 rabbits. In 9 eyes of them extra capsular lens extraction was done and in 3 eyes intracapsular lens extraction was performed. The Barraquer posterior chamber lens was implanted in 6 eyes of 3 rabbits in which the lens was extracted extracapsularly.
The complications developed during operation were perforation of the posterior capsule in an eye implanted with Binkhorst lens and dislocation of a Barraquer posterior chamber lens into the vitreous. Postoperative persistent corneal edema had been observed in 4 eyes with Choyce anterior chamber lens. It seemed to be caused by poor fixation of the implanted lens. In an eye with Choyce anterior chamber lens posterior synechia and increased intraocular pressure developed. At the first week, the second week and a month after operation, an eye in each group was enucleated. The enucleated eye was fixed in 10% formalin for a week and prepared for light microscopic examination. Deformation of the anterior chamber angle, pigment deposition and stretching of the trabecular meshwork were observed in the eyes with a Choyce anterior chamber lens. In an eye with Binl_horst two-loop lens some fibrosis of the pupillary ruff was present. The supporting loops of the Barraquer lens were fixed in the residual capsular bag, the ciliary sulcus, or the stroma of the ciliary body. In the observed eyes no inflammatory reaction was observed.
