Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study evaluates a questionaire designed to measure satisfaction and ophthalmic-related quality of life (QoL) of 300 civilian participants prior to and three months following state-of-the-art laser in situ keratomileusis (LASIK).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The LASIK Quality of Life Collaboration Project (LQOLCP) is a government partnership among the FDA's Center for Devices and Radiological Health (CDRH), the Department of Defense, and the National Eye Institute (NEI). This project examines patient-reported outcomes (PROs) following LASIK surgery. This three-phased project is part of FDA's ongoing effort to better monitor and improve the safety and effectiveness of lasers used in LASIK surgery. PROWL-2 is the third phase of the larger LQOLCP project. The primary objective of PROWL-2 is to explore the psychometric properties of a computer-based questionnaire assessing the patient-reported outcomes of satisfaction and ophthalmic-related quality of life before and over a period of 3 months following LASIK. This questionnaire initially developed and examined in PROWL-1 (a military population) will be examined psychometrically in a civilian population. PROWL-2 is a prospective, multi-center, observational study in which a participant's pre-operative status will serve as the baseline for one-month and three-month post-surgical comparisons. Three hundred (300) participants planning to undergo refractive surgery using LASIK for myopia, hyperopia, or astigmatism will be enrolled in this study from five (5) clinical sites across the United States. Additionally, routine clinical data will be collected pre- and post-operatively (e.g., best corrected visual acuity, manifest refraction, wavefront aberrometry, conreal topography, and other clinical assessments) and questionnaires will be independently administered pre-operatively and at the one-month and three-month post-operative visits.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Investigators will be instructed to base subject eligibility on the Professional Use Information for their specific laser and keratome system, including but not limited to subjects who:
* Are aged 21 years or older.
* Have the ability to give informed consent.
* Speak and read English fluently.
* Have not previously had any form of refractive surgery, including prior LASIK or cataract surgery.
* May benefit from increased spectacle independence.
* Have been determined to be a good candidate for the LASIK procedure based on the investigator's assessment of medical and ophthalmic health, general cognitive function, and physical and social limitations.
* Have a treatment target of bilateral emmetropia. Of note, an eye must be treated within 7 days of the fellow eye.
* Express willingness and potential ability to return for all follow-up examinations through the 3-month follow-up exam under the care of the treating investigator.
* Have access to a computer with internet service.
