Intraocular lens in laboratory animals.

This report summarized the findings in 40 rabbit eyes undergoing extracapsular cataract extraction, 20 of which underwent intraocular lens implantation. The parameters of postoperative evaluation are shown to be limited by the susceptability of the rabbit cornea to corneal edema in the early postoperative phases. The only apparent parameter of statistical importance in this series, however, was the day at which the intraocular lens implanted eye returned to normal compared to the day that the non-implanted eye returned to normal. The fact that there is a 13-day difference in these eyes and the fact that this difference is statistically significant may be important. Pathologic examination of lens implanted eyes has shown that the surgical objectives of intracapsular loop fixation are quite feasible. Microscopic study also showed that there is minimal tissue response to the materials placed in the anterior chamber in this type of surgery.
