Abstract:
Objective To evaluate the visual quality and functions of the civil pilots after corneal refractive surgery (CRS) and to explore the safety and long-term stability of CRS.Methods Two hundred and ninety-seven pilots,who were treated in Ophthalmology Department of West China Hospital,Sichuan University,were selected as subjects in this study.Their visual acuity,refraction,corneal topography,contrast sensitivity and break-up time (BUT) were detected and the subjective questionnaires were surveyed.The pilots were divided by spherical equivalent (SE) into emmetropia group:the SE of any eye was ≤+0.50 D or ≥-0.50 D,refractive error group:the SE of any eye was-0.75--6.00 D and CRS group:the pilots had the history of CRS.Results ①There were 99 pilots (198 eyes) in emmetropia group [SE (0.00±0.50) D];90 pilots (180 eyes) in refractive error group [SE (-2.06±1.75) D];108 pilots (216 eyes) in CRS group [SE (0.00±0.74) D].The SE of 68.1％ pilots in CRS group was within ±0.50 D,90.3％ pilots was with in ±1.00 D.②The uncorrected visual acuity of 85.6％ pilots (185 eyes) of CRS group was ≥1.0 while 98.6％ pilots (213 eyes) achieved ≥0.5.③There were significant differences on BUT,glare contrast sensitivity function-12,corneal astigmatism,surface asymmetry index (SAI) among 3 groups (H =6.910-26.075,P ＜ 0.05).There were no significant differences in the index of visual quality between emmetropes and CRS group except BUT and SAI (H =2.465,4.449,P＜0.017).There were no significant differences in symptom,social activity,mental and psychology domains between emmetropes and CRS group (P＞0.017).Conclusions The long-term visual quality and functions of the pilots by CRS show stable effects and compatible to the criteria of emmetropic pilots.
