purpose: to evaluate corneal thickness changes after soft contact lens (scl) removal in lasik candidates. methods: fifty lasik candidates (100 eyes) with history of daily wear scl for at least 6 months were enrolled in this descriptive study. central corneal thickness was measured by ultrasonic pachymetry immediately after lens removal and then repeated daily at the same time, until the thickne...

acanthamoeba keratitis is a vision- threatening infection and the most important risk factors are contact lenses characteristic symptoms include disproportionately severe ocular pain, epithelial ulcer, ring stromal infiltrate and resistance to antimicrobial treatment. the aim is to report the first cases of acanthamoeba keratitis in yazd in a retrospective study confirmed on histopathological a...

BACKGROUND Microbial corneal infection is the most serious complication of contact lens wear. Contact lens cases are a recognised potential source of pathogens associated with corneal ulcers. METHODS This survey established the incidence of protozoal, bacterial, and fungal contact lens case contamination in 101 asymptomatic daily wear cosmetic contact lens wearers from a domiciliary contact l...

purpose: to determine the sensitivity and specificity of confocal scan in the diagnosis of fungal and acanthamoeba keratitis based on the results of corneal and/or contact lens case smear and culture. method: confocal scan and corneal and/or contact lens case smear and culture were performed in all patients with a clinical diagnosis of infectious keratitis who were referred to labbafinejad medi...

OBJECTIVE To evaluate the risk factors that may contribute to microbial keratitis in contact lens wearers. MATERIAL AND METHOD This prospective case-control study included 52 patients with contact lens related keratitis treated between 1 December 2006 and 15 October 2007 at the Faculty of Medicine, Siriraj Hospital. Controls were sixty-three contact lens users attending with disorders unrelat...

Contact lenses are used as a method of correcting refractive errors. However, their use can be associated with periods of discomfort as well as occasional pathophysiological reactions. This inaugural edition of Optometry Rounds presents the latest findings to allow Optometrists to improve the experience of their patients who wear contact lenses, as well as to share knowledge with respect to con...

PURPOSE To measure the MRD (margin reflex distance) in rigid contact lens wearers and controls by a new method, based on computerized image processing. METHOD The patients were selected from the Contact Lens Sector of the Ophthalmology Service at the "Complexo Hospitalar Santa Casa de Porto Alegre", and they were divided into two groups: the first was formed of rigid contact lens wearers (63 ...

PURPOSE To examine the rates of contamination of contact lens storage cases of refractive surgery candidates and compare the growth yields of the traditional method of culturing and a broth-based method. METHODS Thirty contact lens storage cases of 16 asymptomatic refractive surgery candidates were studied. Samples from the lens storage case fluid were inoculated into Bactec Peds Plus F broth...
