Effect of laser <i>in situ</i> keratomileusis with femtosecond laser on visual quality
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. <p>METHODS: There were 212 eyes in 106 myopes underwent excimer operation.According to the diffe...

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. <p>RESULTS: At 1wk after operation, the contrast sensitivity under photopic environment decreased in the two groups, compared with those before operation(<i>P</i><0.05). The differences of contrast sensitivity before and 3mo after operation were not significant(<i>P</i>>0.05). No statistical significant difference was found in contrast sensitivity under photopic environment at 1wk, 3mo between the two groups(<i>P</i>>0.05). At 1wk after the operation, the contrast sensitivity under scotopic environment decreased in both groups compared with those before operation(<i>P</i><0.05). In SBK group, it decreased more than in FS group(<i>P</i><0.05). After 3mo, the decline of 14.2c/d spatial frequency contrast sensitivity under scotopic environment in the SBK group was more than other frequency. No statistical significant difference was found in the rest frequency contrast sensitivity under scotopic environment before and after operation(<i>P</i>>0.05). After 1wk, contrast sensitivity with glare stimulation in both groups decreased, compared with those before operation(<i>P</i><0.05), while in SBK group, it decreased more than in FS group(<i>P</i><0.05).After 3mo, except that the decline of 14.2c/d spatial frequency contrast sensitivity with glare stimulation in the SBK group was significant compared with those before operation, the contrast sensitivity under glare stimulation in both groups had no significant differences compared with before operation(<i>P</i>>0.05).<p>CONCLUSION: LASIK with femtosecond laser can get a better visual quality than LASIK with microkeratome.http://ies.ijo.cn/cn_publish/2016/6/201606030.pdffemtosecond laserametropiacontrast sensitivitylaser <i>in situ</i> keratomileusislaser <i>in situ</i> keratomileusis |
