Surface Morphology Following Photorefractive Keratectomy

Ophthalmic Surgery, Lasers and Imaging Retina, 1993
ABSTRACT To examine the effects of surface dehydration on corneal surface morphology before and after photorefractive keratectomy, corneas of fresh porcine eyes were deeprthelialized and then immediately fixed or treated according to one of six protocols (four eyes per protocol): dehydrated under the illumination of an operating microscope ...

Photorefractive keratectomy after radial keratotomy

Journal of Cataract and Refractive Surgery, 1994
We report the results of a prospective study that evaluated the efficacy, predictability, and safety of excimer laser photorefractive keratectomy (PRK) to correct residual myopia after radial keratotomy (RK). Using a 193 nm excimer laser, we performed PRK on ten undercorrected myopic eyes that had previous RK surgery.

Photorefractive Keratectomy in 472 Eyes

Journal of Refractive Surgery, 1993
ABSTRACT Between July 1990 and July 1992, 472 eyes were treated with photorefractive keratectomy (PRK) using the ExciMed UV200 193-nanometer excimer laser (Summit Technology, Inc. Watham, Mass). The sphere equivalent refractions ranged between - 1.25 and - 9.60 D, with less than 1 .25 D of astigmatism. Eyes with refractive error up to -6.00 D
