Corneal wavefront aberrations and subjective quality of vision after small incision lenticule extraction

Purpose To analyse in depth the associations between objectively measured corneal higher‐order aberrations (HOAs) and subjectively perceived visual quality after small incision lenticule extraction (SMILE) as quantified with the standardized and clinically validated quality of vision (QOV) questionn...

Description
Summary:Purpose To analyse in depth the associations between objectively measured corneal higher‐order aberrations (HOAs) and subjectively perceived visual quality after small incision lenticule extraction (SMILE) as quantified with the standardized and clinically validated quality of vision (QOV) questionnaire. Methods This cross‐sectional study included patients after bilateral simultaneous SMILE for the treatment of myopia and/or myopic astigmatism with plano target refraction. Scheimpflug imaging (Pentacam HR; Oculus Optikgeräte GmbH, Wetzlar, Germany) was used to objectively quantify corneal HOAs. The standardized and validated QOV questionnaire was employed to gauge patients’ subjectively perceived visual quality regarding frequency, severity and bothering effect of visual disturbances. Results A total of 394 eyes of 197 patients with a mean age of 32.4 ± 7.7 years and a mean postoperative follow‐up of 24.3 ± 14.1 months were included. SMILE induced a statistically significant (p
