Abstract

Objective: To compare the incidence of dry eye after Femtosmile versus Femtolasik. Patients and Methods: In this study we selected 100 eyes of 50 patients divided into two equal groups: group (1); 50 eyes in which Femtosmile (FS) was performed and group (2); 50 eyes in which Femtolasik (FL) was performed. Comparison of the outcomes within 2 weeks, 1, 3, 6 and 12 months postoperatively. Results: There is evidence of dry eye symptoms in both groups after surgery as proved by Schirmer's test, tear meniscus height (TMH) and tear break-up time (TBUT). There is reduction in all of them in both groups. However, these signs and symptoms of dry eye were mostly transient. It returns to near normal values with 3 months and maximum 12 months. It was observed that FS eyes showed less reduction in tear parameters than eyes in FL group with statistically significant difference (p <0.05). Conclusion: Both FS and FL induce transient dry eye symptoms postoperatively. The evidence is mixed and changes after Lasik is controversy between studies, but most of them support dry eye parameters and recovery in corneal sensitivity after FS. FS shows better recovery than FL in the short-term follow-up.
