Abstract:AIM:To introduce a modified pterygium excision, so as to improve the operation quality.
METHODS:To cut the neck of the pterygiumat at limbus, then tear pterygiumat from opposite direction of head on the basis of the original excision. When resistance occurs, point of a knife(15°knife, pointed blade or diamond knife)was employed for cutting on the direction of tangent to cornea. In the process, the operation gave priority to tearing and was supplemented by cutting. A conjunctival flap was taken from the superior temporal and same size as the cut area. Conjunctival transplantation should be firmly stitched on the sclera.
RESULTS:The implementation was taken on 660 eyes. There were only 8 eyes relapsed, and the smoothness and transparency of cornea was superior to the conventional method. Recovery time was shortened obviously.
CONCLUSION:The modified method of reversal tear-cutting, conjunctival autograft and sclera reinforcement fixation is more effective than the conventional transplantation for treating pterygiumat.
