Abstract:
AIM:To investigate the correlation between chronic dry eye and refractive regression after laser in situ keratomileusis (LASIK)for myopia.METHODS:Two hundred and twenty-five eyes of 225 patients were enrolled in this study.Examinations including Schirmer test,tear break-up time(BUT),corneal sensation,and ocular surface staining were performed before and 6 months after LASIK.Dry eye symptoms were assessed using the McMonnies Dry Eye Symptom Survey.Data were analyzed on history and treatment response.RESULTS:Refractive regression after LASIK was related to chronic dry eye.It occurred in 8(25.0%)of 32 patients with chronic dry eye and in 18(9.3%)of 193 patients without dry eye(P＜0.01).CONCLUSION:The risk of refractive regression was increased in patients with chronic dry eye.
