PURPOSE To report the use of photorefractive keratectomy (PRK) with mitomycin-C (MMC) to treat concomitant myopia and visually significant infiltrates associated with epidemic keratoconjunctivitis (EKC). SETTING Ophthalmic Consultants of Long Island, Nassau University, Long Island, New York, USA. DESIGN Interventional case series. METHODS Consecutive patients with myopia and recalcitrant ...

BACKGROUND AND OBJECTIVE Photorefractive keratectomy (PRK) has been extensively evaluated for the correction of myopia. This study was undertaken to assess the safety, efficacy, and reliability of PRK in the correction of hyperopia. PATIENTS AND METHODS There were 28 eyes with refractions of +1 to +7.75 D treated for hyperopia with the Chiron Technolas 217-C excimer laser. Thorough visual ass...

PURPOSE To compare the effect of Homatropine and Diclofenac eye drops for reducing pain after photorefractive keratectomy (PRK). METHODS This randomized, double-masked, interventional study included 32 patients (64 eyes) who underwent bilateral PRK. After operation, patients received Homatropine eye drops in one eye and Diclofenac eye drops in the fellow eye for 48 h. The level of pain was ev...

Background: Mitomycin C (MMC) is used to prevent corneal opacity after photorefractive keratectomy (PRK). This study sought determine the effect of MMC on tear film function PRK in eyes with mild-to-moderate myopia.Methods: prospective, contralateral eye comparison was conducted 30 15 patients low-to-moderate myopia referred Alzahra Eye Hospital, Zahedan, Iran. The control group underwent a bal...

PURPOSE To compare the efficacy and side effects of loteprednol versus fluorometholone after myopic photorefractive keratectomy (PRK). METHODS One hundred and twenty four eyes of 62 patients who underwent PRK were enrolled in this study. One eye of each subject was randomized to receive loteprednol 0.5% and the fellow eye was given fluorometholone 0.1%. Patients were followed up for three mon...

AIM To evaluate the effect of a high dose vitamin A and E supplementation on corneal re-epithelialisation time, visual acuity and haze following photorefractive keratectomy (PRK). METHODS Two groups of 20 patients who underwent myopic PRK were supplemented with either 25 000 IU retinol palmitate and 230 mg alpha tocopheryl nicotinate or a placebo. Clinical outcomes were evaluated up to 360 da...

Photorefractive keratectomy (PRK) remodels corneal stroma to compensate refractive errors. The removal of epithelium and the ablation of stroma provoke the disruption of corneal nerves and a release of several peptides from tears, epithelium, stroma and nerves. A myriad of cytokines, growth factors, and matrix metalloproteases participate in the process of corneal wound healing. Their balance w...

Purpose. To assess refractive and visual outcomes and patient satisfaction of wavefront-guided photorefractive keratectomy (PRK) in eyes with myopia and compound myopic astigmatism, with the ablation profile derived from a new Hartmann-Shack aberrometer. Methods. In this retrospective study, 662 eyes that underwent wavefront-guided PRK with a treatment profile derived from a new generation Hart...

OBJECTIVE To evaluate the results of photorefractive keratectomy (PRK) with mitomycin C in myopia correction after five years. METHODS This is a cross sectional study which included 145 eyes of 74 patients in 18 to 51 years age group that were undergoing Photorefractive keratectomy with mitomycin C using Allegretto Wave Eye-Q 400-Hz excimer laser platform in Markazi Eye Center, Tehran, Iran. ...

To the Editor: We thank Drs. Talamo and Abad and Mr. Lim (Refractive Regression after Excimer Laser Photorefractive Keratectomy. J Refract Surg 1996;12:757[letter]) for their comments and are gratified that their findings support our hypothesis that the refractive regression after photorefractive keratectomy (PRK) is not a result of the thicker regrowth of connnective tissue or epithelium in th...
