Abstract
Recent cataract surgery has a trend to use clear corneal incision that does not require conjunctival peritomy and has fewer complications such as hyphema and ciliary body damage etc. Clear corneal incision also provides less corneal astigmatism and thereby better naked visual acuity. However the side effects of clear corneal incision such as includes wound leakage and associated endophthalmitis, endothelisal cell damage, irregular corneal astigmatism and instability of wounds have been reported continuously. Thus, we have introduced the 3.5mm sized mid limbal incision technique which may compensate the above complications and have rapid visual rehabilitation. Postoperative corneal astigmatism and uncorrected visual acuity of patients with clear corneal incision were compared with the results of scleral pocket incision. The corneal astigmatic changes of both group showed trivial against- the-rule change(0.44-0.12D) in early post operative period. Mid limbal incision group presented a little highter against-the-rule change at post operative 1 wee, but no significiant diffeence was noted sice postoperative 1 month. Uncorrected visual acuity showed no difference between two groups. From these results, we conclude mid limbal incision is an effective procedure that can compensate the disadvantage of both clear corenal incision and scleral pocket incision.
