Studies of aqueous humor proteins in rabbits after posterior chamber lens implantation.

Abstract

In 13 rabbits, 1 month to 1 year after posterior chamber lens implantation/polymethylmetacrylate/, the level of aqueous humor proteins was evaluated and the proteins separation in polyacylamide gel was performed. The studies were also carried out in unoperated eyes of the same animals and control group was composed of the eyes before surgery. It was found that in pseudophakic eyes an increased level of proteins remained during the whole year/the highest one month after surgery, slowly decreasing afterwards/, with the appearance of additional fractions. The moderate increase of the proteins concentration was also observed in unoperated eyes. The increase of aqueous humor proteins in pseudophakic eyes indicates that the presence of polymethyl metacrylate is not completely indifferent to the eyeball in spite of the suggestions derived from the clinical observations.
