Objective To compare the clinical effect of LASIK flap made by femtosecond laser and by microkeratome for high myopia. Methods According to the type of flap creation the patients with myopia undergoing the LASIK were divided into two groups,i.e 90 patients(180 eyes) with the Intralase FS60 as group A,100 patients(200 eyes) with the LASIK as group B. The postoperative I month and 3 months uncorrected visual acuity(UCVA),high order aberration,dry-eyes syndromes including tear film break-up time(BUT),Schirmer I test in two groups were compared. Results The uncorrected visual acuity between 2 groups had no significantly difference at the first month and the 3 rd month of postoperation(P0.05). Aberration:The high order aberration in group A was lower than that in group B with big pupil(P 0.05). One month and three months after the operation,the average BUT and Schirmer I test outcome were not significantly different between the two groups(P0.05). Conclusion Both traditional LASIK flap made and LASIK flap made by femtosecond laser can all achieve good visual acuity and improve quality of life,but the latter is much better than traditional LASIK made flap in improving vision quality.
