Pros and cons of wavefront-guided photorefractive keratectomy

摘要

1. Introduction: Photorefractive keratectomy (PRK) is a widely used keratore-fractive procedure for the correction of refractive error. Conventional PRK aims to treat lower order aberrations, sphere and cylinder, whereas wavefront-guided (WFG) PRK aims to treat both lower and higher order aberrations (HOAs). The currently available literature shows that WFG PRK is not only safe and predictable, but also has excellent visual outcomes and patient satisfaction [1-5]. Nonetheless, there are important considerations when counseling patients regarding refractive surgical options and expectations. Here we review the pros and cons of WFG PRK.
