Changes in corneal wavefront aberrations with aging.
PURPOSE To investigate whether corneal wavefront aberrations vary with aging. METHODS One hundred two eyes of 102 normal subjects were evaluated with videokeratography. The data were decomposed using Taylor and Zernike polynomials to calculate the monochromatic aberrations of the cornea for both small (3-mm) and large (7-mm) pupils. RESULTS For a 3-mm pupil, the amount of total aberrations ...
متن کاملRepeatability of corneal first-surface wavefront aberrations measured with Pentacam corneal topography.
PURPOSE To assess the repeatability of corneal wavefront aberrations derived from Pentacam (Oculus) corneal topography. SETTING Flinders Eye Centre, Flinders Medical Centre, Bedford Park, South Australia, Australia. METHODS Forty-five normal participants and 10 participants with keratoconus were tested. Intraobserver and interobserver repeatability was determined using 4 observers within an...
متن کاملChanges of Corneal Wavefront Aberrations in Dry Eye Patients after Treatment with Artificial Lubricant Drops
Purpose. To evaluate the corneal aberration changes in dry eye patients after treatment with artificial eye drops. Methods. Thirty mild to moderate dry eye patients treated with artificial eye drops and twenty comparable dry eye patients were recruited as controls. Anterior corneal aberrations over 3 mm and 5 mm analytical zones including total, 3rd to 5th high order aberrations (HOAs), spheric...
متن کاملEvaluation of total and corneal wavefront high order aberrations for the detection of forme fruste keratoconus.
PURPOSE To investigate the application of anterior corneal and ocular aberrations in detecting mildly ectatic corneas. METHODS This study retrospectively reviewed the data of 220 eyes separated into three groups by the NIDEK Corneal Navigator System automated corneal classification software: normal (N) (n = 123); forme fruste keratoconus (N topography with contralateral KC) (n = 34); and KC (...
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...
