Clinical observation of corneal refractive stability time after excision of pterygium

Abstract

AIM: To observe the corneal refractive state stability time and changes of corneal refraction after excision of pterygium.METHODS:There were 46 cases(54 eyes), who had undergone excision of pterygium, randomly selected for corneal topography examination operated on the 3rd, 7th, 14th, 30th and 90th day after surgery. And statistic analysis was undertaken.RESULTS:Astigmatism after pterygium excision decreased significantly. Ks value, astigmatism in the 3rd postoperative day compared with that in other observation phases showed differences of statistical significance(Pth days compared with that in other observation phases showed differences of no statistical significance(P>0.05). CONCLUSION: Corneal refractive status is stable in 7 days afterpterygium excision surgery.
