Abstract: : Purpose: To evaluate visual performance following LASIK surgery for myopia and myopia with astigmatism using the Refractive Status and Vision Profile (RSVP) questionnaire. Methods: As part of an ongoing prospective study of visual performance after LASIK, the RSVP questionnaire was self-administered by 50 patients. Eligiblity was limited to myopes ages 18-34 with a spherical equivalent refraction of ≤5.0 D and astigmatism ≤1.5 D. Changes in total RSVP score and subscales scores (concern, functioning, driving, symptoms, optical problems, glare, and trouble with corrective lenses)were assessed. Outcome variables included best-corrected spectacle visual acuity, postoperative uncorrected visual acuity (UCVA) and residual spherical equivalent refractive error. Results:: The mean age of 22 men and 28 women was 28.2 years. Mean preoperative spherical equivalent refractive error was -3.25 +/-1.03 D. Preoperative best-corrected Snellen visual acuity was 20/20 or better in all eyes. At 3 months postoperatively, data were collected from 34 patients. UCVA of 20/20 or greater was recorded in 88.2% (60/68) of eyes. Mean 3-month postoperative spherical equivalent refraction was -0.08 +/-0.48 D. Two eyes were retreated for residual refraction at 4 months postoperatively. Twenty-three patients reached 6-month follow-up. Ninety-eight percent (45/46) of eyes achieved UCVA of at least 20/20. Mean spherical equivalent refraction at 6 months was -0.09 +/-0.25 D. A change of ≥2 units in total RSVP or subscale scores was considered significant. Three months after surgery, 52.9 % (18/34) of patients reported an improvement in total score. Overall, no patients noted significant worsening. Five of 10 subscales showed improvement while 3 subscores showed a decline at 3 months. At 6 months postoperatively, 56.5% (13/23) reported an increase in total score compared to a decrease in 4.3% (1/23) of patients. Three subscales recorded improvement, 2 showed worsening and no significant change was noted in 5 categories. Conclusion: Using traditional outcome measures and the RSVP questionnaire to evaluate visual performance, a substantial number of patients report equivalent or improvement in quality of vision following LASIK compared to preoperative vision with glasses or contact lenses.
