AIM:To evaluate the effect of contact lens applied in pterygium excision. ·METHODS:Totally 33 patients 40 eyes underwent pterygium excision combined with conjunctival flap transplantation in our hospital and they were divided equally into A group(contact lens for 5 days) and B group(routine ensheathe withnot contact lens)at random. Corneal irritation and healing of epithelium were observed in these two groups. ·RESULTS:Corneal irritation in A group was much better than that of the B group on the postoperation day 1 and 3. Shorter time healing of epithelium was seen in A group. ·CONCLUSION:Contact lens can alleviate corneal irritation significantly after pterygium excision; shorten the healing time of epithelium.
