Multi-Site Study of Patient Reported Vision Quality and Dry Eye Following LASIK.

Area of Science:

• Ophthalmology
• Refractive Surgery
• Patient-Reported Outcomes

Background:

• Laser-assisted in situ keratomileusis (LASIK) is a common refractive surgery.
• WaveLight technology offers advanced options for correcting myopia and myopic astigmatism.
• Assessing patient satisfaction is crucial for evaluating the success of refractive procedures.

Purpose of the Study:

• To evaluate patient satisfaction with vision after WaveLight LASIK.
• To assess the incidence and bothersomeness of visual disturbances post-surgery.
• To determine the prevalence of dry eye symptoms following the procedure.

Main Methods:

• An ambispective, multicenter observational study.
• Included patients who underwent Wavefront Optimized or Contoura LASIK using the Wavelight EX500 laser.
• Utilized modified PROWL, OSDI, and dry eye questionnaires for data collection.

Main Results:

• 95% of patients reported high satisfaction with their vision post-LASIK.
• Visual disturbances like double images, glare, halos, and starbursts were infrequent and minimally bothersome.
• The mean Ocular Surface Disease Index (OSDI) score indicated a normal ocular surface in most patients.

Conclusions:

• WaveLight LASIK demonstrates high patient satisfaction with vision approximately 12 months post-procedure.
• Visual disturbances are reported with low frequency and low bothersomeness.
• The procedure is highly recommended by patients, with a majority experiencing no dry eye symptoms.
