Abstract

In order to compare the amount of surgically induced astigmatism among sutureless group(Group 1),10-0 nylone suture group(Group 2),and using tissue adhesive group(Group 3),we analysed a series of rabbit cataract surgery cases in these three groups. We performed cataract surgery on 30 eyes of 15 rabbits by Irrigation and aspiration technique. After cataract surgery,10 eyes by sutureless technique,10 eyes were closed by conventional 10-0 nylon suture technique, and 10 eyes by tissue adhesive(Beriplast) technique.We collected keratometric data before and after surgery(At 1,2,4,8 weeks).In postoperative astigmatic change,three groups had the distinct features in the evolution for postoperative astigmatism.The group 1 showed early against-the-rule(ATR)astigmatism,which advanced ATR and showed about 0.5D astigmatic change at 8 weeks.The group 2 showed early with-the-rule(WTR)astigmatism about 1.13D,which advanced toward ATR from 1week.The group 3 showed little ATR about 0.2D,which was minimal change in astigmatism.At 8 weeks after operation,there was no signifi-cant difference in the astigmatic change among the three groups(P>0.05), which were no complications observed. In this study,the tissue adhesive(Beriplast)seem to be a simple,effective and less induced astigmatic changing corneoscleral suture technique than other suture techniques
