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...
متن کاملVisual performance after excimer laser photorefractive keratectomy for high myopia
PURPOSE To evaluate the efficacy, safety, predictability, and visual performance of excimer laser photorefractive keratectomy (PRK) for myopia greater than -8 diopters (D). METHODS Fifty-four patients (104 eyes) with myopia from -8D to -13D and cylinder up to -4D received surface ablation technique with the Allegretto wave version 1009-1 excimer laser to correct their refractive error. The pa...
متن کاملRefractive regression after photorefractive keratectomy.
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...
متن کاملPhotorefractive keratectomy for hyperopia after radial keratotomy.
BACKGROUND Progressive hyperopia is a common complication following radial keratotomy. METHODS Ten eyes of ten consecutive patients with hyperopia after radial keratotomy between +1.75 and +4.00 diopters (D) were treated with the hyperopia module of the Nidek Model EC-5000 excimer laser. The mean preoperative uncorrected visual acuity was 0.38 (20/60+). RESULTS After excimer laser photorefr...
متن کاملContact lens fitting after photorefractive keratectomy.
AIMS/BACKGROUND This study evaluated contact lens fitting and the longer term response of the photorefractive keratectomy (PRK) cornea to lens wear. In PRK for myopia problems such as regression, anterior stromal haze, irregular astigmatism, halo aberration, and anisometropia have been reported. Certain patients therefore require contact lens correction to obtain best corrected visual acuity (B...
