Incidence, outcomes, and risk factors for retreatment after wavefront-optimized ablations with PRK and LASIK.

Purpose: To analyze and compare retreatment rates after wavefront-optimized photorefractive keratectomy (PRK) and LASIK and determine risk factors for retreatment.

Methods: A retrospective chart review was performed to identify patients undergoing PRK or LASIK with the wavefront-optimized WaveLight platform from January 2005 through December 2006 targeted for a piano outcome and to determine the rate and risk factors for retreatment surgery in this population.

Results: Eight hundred fifty-five eyes were analyzed, including 70 (8.

Higher-order aberrations after wavefront-optimized photorefractive keratectomy and laser in situ keratomileusis.

Purpose: To analyze the changes in higher-order aberrations (HOAs) that occur after wavefront-optimized photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK).

Setting: Emory Eye Center and Emory Vision, Atlanta, Georgia, USA.

Methods: This retrospective analysis comprised eyes that had PRK or LASIK from June 2004 through October 2005.
