Patient Reported Outcomes With WaveLight Plus LASIK

Not yet recruiting
Conditions
Myopia
Astigmatism
Registration Number
NCT07084844
Lead Sponsor
Mann Eye Institute
Brief Summary

This study is a single-site, single-arm, prospective, observational study of subject satisfaction, quality of vision, and quality of life after bilateral LASIK surgery. Subjects will be assessed up to 3 months post-operatively. Clinical evaluations will include refractive outcomes, visual acuity, and administration of the adapted PROWL and the Quality-of-Life Impact of Refractive Correction (QIRC) Questionnaire.

Exclusion Criteria
  • Subjects with any prior ocular surgery

Primary Outcome Measures
NameTimeMethod
Mean score of satisfaction with uncorrected vision after wavelight plus LASIK based on PROWL-SS Questionnaire preoperative vs postoperative (question #1 [Q1] only).3 months postoperative
Secondary Outcome Measures
NameTimeMethod
PROWL-SS Questionnaire3 months postoperative

PROWL-SS can be used to assess satisfaction with vision and the existence, bothersomeness and impact on usual activities in the last 7 days of four visual symptoms - double images (8 items), glare (8 items), halos (8 items) and starbursts (8 items). Subjects select one of 6 responses for each question. Responses are scaled from 0 to 100, with 0 being a worse overall outcome and 100 being a better overall outcome for the existence, bothersomeness and impact on usual activities in the last 7 days of four visual symptoms - double images (8 items), glare (8 items), halos (8 items) and starbursts (8 items).

OSDI Score3 months postoperative

The OSDI© is assessed on a scale of 0 to 100, with higher scores representing greater disability. The index demonstrates sensitivity and specificity in distinguishing between normal subjects and patients with dry eye disease. The OSDI© is a valid and reliable instrument for measuring dry eye disease (normal, mild to moderate, and severe) and effect on vision-related function.

Uncorrected distance visual acuity3 months postoperative

% of eyes in each level of uncorrected visual acuity (e.g. 20/20, 20/16, 20/12.5, 20/10 with logMAR chart).
