Wavelight Plus Sightmap-LASIK vs. Wavefront-Optimized-LASIK

28. september 2026 oppdatert av: 59th Medical Wing

Clinical Outcomes of Contralateral Wavelight Plus-LASIK vs. Wavefront-Optimized LASIK

The goal of this clinical trial is to learn if the wavelight plus Sightmap (WLP) method or the wavefront-optimized (WFO) method for calculating LASIK customization treatment gives better vision, better satisfaction, and fewer symptoms afterward. The main questions it aims to answer are:

  1. Does the WLP method provide better vision than WFO method?
  2. Does the WLP method provide better patient satisfaction and less symptoms than WFO method?

Researchers will compare two methods for calculating LASIK customization treatment to determine which one is better.

Participants will:

  1. Receive LASIK in both eyes: one eye will receive WLP-LASIK and the other will receive WFO-LASIK.
  2. Be in the study for about three months and will have six clinic visits: a pre-op qualification exam, the surgery visit, and follow-up visits on 1 day, 1 week, 1 month, and 3 months after surgery.
  3. Have several eye test to assess vision and complete a symptom questionnaire. This questionnaire will take approximately ten (10) minutes to complete in person during.

Detaljert beskrivelse

Both WLP method and WFO method for calculating LASIK customization treatment are FDA-approved and are both performed routinely as standard of care surgery in the US Military. However, there is limited literature comparing quality of vision after WLP-LASIK and WFO-LASIK refractive surgery. Our objective is to study the 3-month visual outcomes (high and 5% low contrast visual acuity, refractive error, higher order aberrations, contrast sensitivity) and subject-reported satisfaction with vision and quality of vision (i.e., double vision, glare, starburst, halos, etc.) using the PROWL-SS questionnaire following contralateral WLP-LASIK and WFO-LASIK. This is a prospective randomized contralateral study, including 49 subjects. Once consented to participate in the study, subjects will have a comprehensive ocular examination to determine eligibility to undergo simultaneous WLP-LASIK surgery in one eye and WFO-LASIK on the contralateral eye to correct myopia. Surgical treatment will be randomized so there is a 50% chance to receive WLP-LASIK on the right eye and WFO-LASIK on the contralateral eye. Subjects will receive standard of care topical ophthalmic antibiotic and steroid drops. Visual outcomes and patient self-reported symptoms will be assessed at day 1, week 1, month 1, and month 3.

Possible Symptoms Score ranges from 1 (extremely bothersome) to 5 (not at all bothersome). Lower value indicates worse symptoms.
