Purpose: To evaluate patient-reported quality of vision before and after laser in situ keratomileusis (LASIK) surgery.
Subjects and methods: This study involved 140 patients who underwent LASIK surgery at Baptist Eye Clinic, Kyoto, Japan. Each patient was asked to respond to the Refractive Status and Vision Profile (RSVP) questionnaire prior to surgery and at 6-months and 5.5-years postoperative. In each patient, we defined the eye with better uncorrected visual acuity (VA) or with less refractive error as the better eye, and the other eye as the worse eye.
Results: Even in the worse eyes, the percentage of eyes with an uncorrected VA of decimal 0.5 or greater was 93.5% at 6-months and 88.6% at 5.5-years postoperative. The mean preoperative total RSVP score was 37.1, yet that score significantly improved at 6-months postoperative (p<0.001) and remained the same throughout the 5.5-year follow-up period.
Conclusion: The patient-reported quality of vision post LASIK surgery was improved and remained improved throughout the 5.5-year follow-up period
