Abstract:AIM: To evaluate the clinical effect of fresh amniotic membrane transplantation in combination with bandage type corneal contact lens in the treatment of pterygium.
METHODS: This study was a prospective analysis of 600 pterygium excision patients(600 cases, 600 eyes)in the He Eye Hospital from January 2016 to June 2016. The patients were randomly and evenly divided into two groups: observation group and control group, 300 cases in each group(300 eyes). Observation group wore the bandage type corneal contact lens after surgery and took it down at fifth day. The control group did not. The degree of pain after surgery were evaluated at 2h, 1, 3 and 5d after surgery. The clinical outcomes in these two groups were compared in a 12mo postoperative follow-up observation.
RESULTS: There were no significant differences between the observation and control group in the percentage of age and gender and size of the pterygium(P>0.05). After surgery, the degree of pain of treatment group significantly decreased compared to control group, the difference was statistically significant(P<0.01). There were no significant differences between the 2 groups comparing treatment outcomes as the recurrence rate(P>0.05).
CONCLUSION: Bandage contact lenses could significantly release pain response after pterygium excision. But it can not reduce the recurrence rate.
