Objective To investigate the objective optical quality and intraocular scatter after femtosecond laser and mechanical microkeratome LASIK for myopia correction.Methods This was a retrospective study.Seventy-two myopic eyes of 72 patients who conformed to the criteria for LASIK in preoperative examinations were enrolled.Patients had a best corrected visual acuity (BCVA) of ≥ 1.0.Thirty-five eyes of 35 patients were treated with LASIK with femtosecond laser flap preparation (F-LASIK),male∶female ratio=1∶1.3; 37 eyes of 37 patients were enrolled in the control group with microkeratome flap preparation (M-LASIK),male∶female ratio=l∶2.7.Optical quality parameters were measured in each patient 1 year after the LASIK surgeries:modulation transfer function cutoff frequency (MTFcutoff,cycles per degree,c/d),Strehl2D ratio (SR) and objective scatter index (OSI).Results Mean age was 26.71±5.89 years in the F-LASIK group and 28.67±6.62 years in the M-LASIK group;mean spherical equivalent refraction (SE) was-6.18±2.25 D in the F-LASIK group and-6.62±1.78 D in the M-LASIK group.Neither group had a reduction in BCVA.The safety index was 1.06±0.12 in the F-LASIK group and 1.05±0.14 in the M-LASIK group (t=0.382,P＞0.05),while the efficacy index was 1.04±0.15 in the F-LASIK group and 1.04±0.14 in the M-LASIK group (t=0.156,P＞ 0.05).Mean postoperative MTFcutoff was 33.44±6.77 c/d after F-LASIK,which was significantly greater than the mean value of 29.14±9.08 c/d in the M-LASIK (t=2.264,P＜0.05); mean SR was 0.18±0.01 in the F-LASIK,which was significantly greater than the mean value of 0.16±0.01 in the M-LASIK (t=2.439,P＜0.05).Mean OSI was similar between the two groups,with 0.77±0.39 in the F-LASIK group and 1.07±0.63 in the the M-LASIK group (Z=-1.809,P＞0.05).Conclusion Patients acquire better objective optical quality after femtosecond laser LASIK.However,further study is needed to investigate the factors associated with MTFcutoff and intraocular scatter.
