Vision Related Quality of Life in Myopia; Photorefractive Keratectomy versus Nonsurgical Optical Correction

Purpose: to compare quality of life (qol) in myopic patients who underwent photorefractive keratectomy (prk) with that of myopic spectacle or contact lens users.methods: this observational comparative study was performed on 102 low to moderate myopic patients who had undergone prk at least 6 months ago and 106 myopic spectacle or contact lens wearers. vision related qol and its correlation with demographic variables, visual acuity and refractive status were compared between the two groups. qol was measured using a validated translated version of the visual function questionnaire (vfq-25) which contains 25 questions in 12 subscales with a total score of zero to 100.results: mean total qol score was 97.0±4.4 and 86.1±10.7 in prk and nonsurgical groups respectively [mean difference (d)=11, p0.05). overall, 10 out of 12 qol subscales were significantly higher in the prk group (p0.9) and ocular pain (d=3.1, p=0.3) were not significantly different between the study groups.conclusion: correction of myopia using prk is associated with higher qol scores in most subscales as compared to spectacle or contact lens wear
