the effect of topical diclofenac sodium 0.1% on the corneal epithelial healing after photorefractive keratectomy

Corneal epithelial healing after photorefractive keratectomy: analytical study.

PURPOSE To characterize the velocity of epithelial migration after photorefractive keratectomy (PRK) with 3 different corneal ablation patterns. SETTING Department of Ophthalmology, Catholic University of Rome, Rome, Italy. METHODS Fifteen patients (30 eyes) with mild to moderate myopia and with simple to compound myopic astigmatism were enrolled for this study. The surgical procedure consi...

Effect of preemptive topical diclofenac on postoperative pain relief after photorefractive keratectomy.

PURPOSE To assess the prophylactic effect of preoperative application of topical diclofenac on postoperative pain control in patients having photorefractive keratectomy (PRK). SETTING Farabi Eye Hospital, Tehran University of Medical Sciences, Tehran, Iran. DESIGN Randomized masked clinical trial. METHODS In this paired-eye study, patients having bilateral PRK received 1 drop of diclofena...

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...

Corneal Epithelial Remodeling and Its Effect on Corneal Asphericity after Transepithelial Photorefractive Keratectomy for Myopia

Purpose. To evaluate the changes in epithelial thickness profile following transepithelial photorefractive keratectomy (T-PRK) for myopia and to investigate the effect of epithelial remodeling on corneal asphericity. Methods. Forty-four patients (44 right eyes) who underwent T-PRK were retrospectively evaluated. Epithelial thickness was measured using spectral-domain optical coherence tomograph...

Corneal ectasia after photorefractive keratectomy.

Two patients developed corneal ectasia after photorefractive keratectomy (PRK). Case 1 had evidence of early keratoconus preoperatively, with manifest refractions of -4.00 +2.50 x 160 (20/20) in the right eye and -7.00 +3.00 x 180 (20/30) in the left eye; thin corneas (472 microm and 441 microm, respectively); and inferior paracentral steepening in the right eye and central steepening in the le...
