Epi-Bowman keratectomy versus alcohol-assisted photorefractive keratectomy: wound healing and complications

Photorefractive keratectomy: implications of corneal wound healing.

Photorefractive keratectomy: implications of corneal wound healing

Photorefractive keratectomy (PRK) with an argon fluoride laser (193 nm) was developed to alter the refractive power of the eye predictably and permanently. At PRK the central corneal epithelium is debrided mechanically and a disc 4 to 6 mm in diameter is ablated into the anterior stroma using computer controlled algorithms to control the depth of the wound. Theoretically for corrections of up t...

Alcohol-assisted versus Mechanical Epithelium Removal in Photorefractive Keratectomy

PURPOSE To compare the outcomes and complications of alcohol-assisted versus mechanical corneal epithelial debridement for photorefractive keratectomy (PRK). METHODS This randomized controlled trial included 1,250 eyes of 625 patients undergoing PRK for correction of myopia and myopic astigmatism. Each patient was randomly assigned to alcohol-assisted or mechanical epithelial removal. RESUL...

Laser-assisted subepithelial keratectomy (LASEK) without alcohol versus photorefractive keratectomy (PRK).

PURPOSE To evaluate epithelial healing and visual outcome after laser-assisted subepithelial keratectomy (LASEK) without alcohol de-epithelialization and to compare this technique to photorefractive keratectomy (PRK) in myopia. METHODS In a series of 1953 patients undergoing bilateral myopic PRK, an epithelial flap could be obtained by manual de-epithelialization in the left eye of 56 patient...

Results and Complications of Photorefractive Keratectomy

Materials and Methods: This retrospective study was conducted at Laser Vision Center, Model Town, Lahore. It comprised of 200 patients(400 eyes) that underwent PRK on Summit Apex Plus excimer laser from 20 Feb 2004 to 3 June 2005. All consecutive patients with complete relevant data were included in the study. Three months postoperatively, the uncorrected visual acuity and complications in each...
