Corneal biomechanical properties after laser-assisted in situ keratomileusis and photorefractive keratectomy
BACKGROUND The purpose of this study was to evaluate the effects of laser-assisted in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK) on corneal biomechanical properties. METHODS We used the ocular response analyzer to measure corneal hysteresis (CH) and corneal resistance factor (CRF) before and after refractive surgery. RESULTS In all, 230 eyes underwent LASIK and 115 ey...
متن کاملComparison of corneal wavefront aberrations after photorefractive keratectomy and laser in situ keratomileusis.
PURPOSE To compare changes in the corneal wavefront aberrations after photorefractive keratectomy and laser in situ keratomileusis. METHODS In a prospective randomized study, 22 patients with bilateral myopia received photorefractive keratectomy on one eye and laser in situ keratomileusis on the other eye. The procedure assigned to each eye and the sequence of surgery for each patient were ra...
متن کاملComparison of Changes in Corneal Biomechanical Properties after Photorefractive Keratectomy and Small Incision Lenticule Extraction
OBJECTIVES To compare the postoperative biomechanical properties of the cornea after photorefractive keratectomy (PRK) and small incision lenticule extraction (SMILE) in eyes with low and moderate myopia. MATERIALS AND METHODS We retrospectively examined 42 eyes of 23 patients undergoing PRK and 42 eyes of 22 patients undergoing SMILE for the correction of low and moderate myopia. Corneal hys...
متن کاملLong-term corneal keratoctye deficits after photorefractive keratectomy and laser in situ keratomileusis.
PURPOSE To measure changes in keratocyte density up to 5 years after photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK). METHODS This was a prospective, nonrandomized clinical trial. Eighteen eyes of 12 patients received PRK to correct a mean refractive error of -3.73 +/- 1.30 D, and 17 eyes of 11 patients received LASIK to correct a mean refractive error of -6.56 +/- ...
متن کاملChanges in the posterior cornea after laser in situ keratomileusis and photorefractive keratectomy.
PURPOSE To study the changes in posterior corneal elevation after laser in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK) using Scheimpflug topography with the Pentacam anterior segment imaging system (Oculus, Inc.). SETTING Department of Ophthalmology, Albany Medical Center, and a private clinical practice, Albany, New York, USA. METHODS In this prospective study, 121 co...
