ABSTRACT
AIM:To observe the changes of tear film on the patients after laser in situ keratomileusis ( LASIK) with corneal flap created by femtosecond laser with Oculus corneal topography. METHODS:Totally 120 myopic patients (240 eyes) were collected who underwent femtosecond laser surgery LASIK from August to September 2013, and these patients can be followed up for 3mo. Tear break-up time ( BUT) and tear meniscus height ( TMH ) with Oculus corneal topography were recorded preoperatively and postoperatively at 1wk;1, 2 and 3mo. RESULTS: Oculus BUT: there existed obvious differences (P=0. 012, 0. 000, 0. 023 0. 05 ) existed in 3mo compared with the preoperative level. TMH:there existed obvious differences (P=0. 025, 0. 019, 0. 0260. 05 ) existed in 3mo compared with the preoperative level. CONCLUSION: Femtosecond laser surgery affects the stability of the tear film at a certain time and a certain extent. The mechanism related to many factors. It is temporary and lighted.
