[The use of cyanoacrylate tissue adhesive in the pterygium excisions with amniotic membrane transplantation].

PURPOSE: To find the proper way to use the cyanoacrylate tissue adhesive (CTA) in the pterygium excisions with amniotic membrane transplantation and To evaluate the therapeutic effects of it.

METHOD: A prospective randomized clinical trial was carried out in 27 patients (32 eyes) who would have pterygium excision. They were divided into 2 groups randomly: 15 eyes in the CTA group, 17 eyes in the suture group. We evaluate the benefits of them with the respect to surgery time and postoperative sighs and symptoms.

RESULTS

Average surgery time was 15.8 minutes for CTA group and 23.7 minutes for sutures, P < 0.05. The postoperative sighs were much more light in CTA group. The average pain was significantly lower when CTA had been used, P < 0.05. And the amniotic membrane was attached much better. The two groups have no significant difference in the other aspects.

CONCLUSION

Using CTA instead of sutures when attaching the amniotic membrane in pterygium surgery shortens surgery time significantly and improve the postoperative sighs and symptoms. It's easy, safe and effective.
