Comparison Of The Results With Superior And Nasal Hinge Of Corneal Flaps Created By Femtosecond Laser-assisted LASIK For Myopia

PurposeTo compare curative evaluation with superior and nasal hinge of corneal flaps on visual acuity,refraction,higher order aberration and dry eye after femtosecond laser-assisted LASIK for myopia.MethodsIt was a self contra-lateral eye study.A total of 22 patients(44 eyes)who had undergone femtosecond laser-assisted LASIK for myopia.Patients were divided into two groups based on the hinge positions of corneal flaps.Visual acuity,refraction,higher order aberration,height of tear meniscus,non-invasive tear break-up time(NIBUT),McMonnies Questionnaire were recorded preoperatively and postoperatively at 1 week and 1,3 month.ResultsNo significant differences were observed in any of the parameters between left and right eyes at any time point(P>0.05).ConclusionsDifferent hinge positions of corneal flaps had no significant difference on visual acuity,refraction,higher order aberration,dry eye after femtosecond laser-assisted LASIK for myopia.
