Contact 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...
متن کاملTopical tetracaine with bandage soft contact lens pain control after photorefractive keratectomy.
PURPOSE A major disadvantage of photorefractive keratectomy (PRK) is pain and discomfort in the first three postoperative days. We tried to assess the efficacy and safety to the cornea of a limited amount of topical tetracaine given to patients for use when needed to manage severe pain. METHODS Sixty-nine eyes of 49 patients who underwent PRK between June 21, 1996 and June 15, 1998 by a singl...
متن کاملIntraocular lens power calculation for cataract surgery after photorefractive keratectomy.
OBJECTIVE To assess intraocular lens (IOL) power calculations in patients undergoing cataract surgery after excimer laser photorefractive keratectomy (PRK) for myopia. METHODS Four eyes of two patients underwent phacoemulsification with IOL implantation after PRK for myopia. The estimated refractive error that would have been induced had the IOL predicted for emmetropia been implanted was cal...
متن کاملCorneal 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 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...
