Effect of laser in situ keratomileusis with femtosecond laser on visual quality / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

?AIM:To compare the changes of the contrast sensitivity after LASIK with femtosecond laser and microkeratome and to explore the influence of different methods making corneal flap on visual quality.? METHODS: There were 212 eyes in 106 myopes underwent excimer operation . According to the different methods of operation, they were divided into two groupsmicrokeratome group ( SBK group ) and femtosecond laser group ( FS group) . FS group a total of 112 eyes in 56 patients received LASIK with femtosecond laser. SBK group a total of 100 eyes in 50 patients received LASIK with microkeratome. Contrast sensitivity was detected preoperatively, and 1wk, 3mo postoperatively and compared between the two groups.? RESULTS: At 1wk after operation, the contrast sensitivity under photopic environment decreased in the two groups, compared with those before operation ( P0. 05). No statistical significant difference was found in contrast sensitivity under photopic environment at 1wk, 3mo between the two groups ( P>0. 05 ). At 1wk after the operation, the contrast sensitivity under scotopic environment decreased in both groups compared with those before operation ( P0. 05). After 1wk, contrast sensitivity with glare stimulation in both groups decreased, compared with those before operation ( P0. 05).?CONCLUSION:LASIK with femtosecond laser can get a better visual quality than LASIK with microkeratome.
