Effect of corneal refractive surgery on accommodative and binocular dysfunctions among civilian pilots in Southwest China

Abstract Background To analyze whether corneal refractive surgery (CRS) is associated with the distribution of different accommodative dysfunctions (ADs) and binocular (BDs) in civilian pilots. A further aim was to percentages visual symptoms ADs and/or BDs this population. Methods One hundred eight pilots who underwent CRS from January 2001 July 2012 (age: 30.33 ± 4.60 years) were enrolled, mean preoperative SE − 1.51 1.15 D (range: 1.00- 5.00 D). Ninety-nine emmetropic 29.64 3.77 age- sex-matched group also enrolled. Refractive status, tests each subject performed. Visually related quantified using 19-item College Optometrists Vision Development Quality Life (COVD-QOL) questionnaire. The 19 items summed obtain symptom scores that might indicate dysfunctions. chi-square test used differences between groups. Mann-Whitney U compare normal vision. Results No significant difference observed groups overall prevalence (15.7% 15.2% groups, respectively; P = 0.185). present 4.63% 3.03% group, respectively. 11.1% 12.1% respectively, yielding no or (AD: 0.094; BD: 0.105). Pilots had significantly more than vision ( p < 0.001). Conclusions for low-moderate myopia not impact functions. commonly occur both emmetropia undergo CRS, are increased symptoms. This study confirms importance a full assessment functions detecting remedying these specific
