Summary
The aim of the study was to evaluate the suitability of implantating of an intraocular lens (IOL) in an anterior chamber following an intracapsular lens extraction. IOLs, manufactured by Domilens (Vetlens, France), were implanted in both eyes of five Angora rabbits which were used as model animals. The implants were adjusted by removing one of two haptics and using the other one to fix the IOL in the 12 o'clock position (in front of the corneal limbus) after turning it into a "loop" by means of a thermocauter. The intracapsular lens extraction was performed after opening the anterior eye chamber by corneal incision. The surgical wound was closed by nonresorbable material - Ethilon 10/0 using an individual suture technique. In the 3-month postoperative period we examined the animals for corneal oedema, aqueous humour opacity, irritation of the uvea, and the healing of the wound.
Corneal oedema and aqueous humour opacity were observed in one eye (out of 10 eyes operated on) and of low intensity only. Irritation of the uvea was observed in 4 cases up to day 14 post operation. It was associated with manipulating the instruments in the anterior chamber during the operation.
A favourable course of healing was indicated by the fact that on day 11 post operation we recorded a slight deposition of fibrin on several sites in only one eye; by day 17 no deposition of fibrin on the implanted lenses was observed.
