Abstract

Four groups of cataract patient having phacoemusification wlth varying incision and incision length were studied. Posterior limbal lncision with 7mm, 5.25mm length and continous suture were done on group 1(40 eyes) and 2(20 eyes).Scleral tunnel incision. 2-2 5mm apart from posterior limbus wlth 6.5mm, 5mm length and no-suture were done on group 3(40 eyes) and 4(26 eyes). Mean keratometric astigmatic changes with vector analysis postoperative 2 month were statistically significant between group 1,2 and group 3,4(p<0.05), but we found no statisical significance between group 3 and 4(p>0.05). Postoperative hyphema(including mlcrohyphema) were observered on 2 eyes(5%) of group 3 and 3 eyes(11.5%) of group 4 and indence was much higher in sutureless group than posterior limbal incision group Nd-Yag laser posterior capsulotomy were done on 3 eyes with posterior capsular staining with blood Sutureless technique using phacoem usification and scleral tunnel incision could have earlier and better usual outcome and much stable wound w1th minimal induced astigmatic changes regardless of incision length.
