PURPOSE To evaluate the feasibility and efficacy of mini-scleral design (MSD) contact lenses to treat keratoconus patients who were unsatisfied with the results of corneal inlay. METHODS In this prospective interventional case series, 9 eyes of 6 keratoconus patients who were unsatisfied with the results of corneal inlay were fitted with MSD contact lenses. Demographic data, uncorrected visua...

PURPOSE UVB radiation from sunlight is known to be a risk factor for human cataract. The purpose in this study was to investigate the ability of a class I UV-blocking soft contact lens to protect against UVB-induced effects on the ocular tissues of the rabbit in vivo. METHODS Eyes of rabbits were exposed to UVB light for 30 minutes (270-360 nm, peak at 310 nm, 1.7 mW/cm(2) on the cornea). Eye...

The evolution of contact lens technology and clinical practice over the past three decades has been remarkable, with dramatic improvements in material biocompatibility, better lens designs and care systems, and more flexible and convenient modalities of wear. However, our approach to the aftercare examination has remained conservative, with the general modus operandi having not fully evolved fr...

The aim of this paper was to assess soft contact lens replacement habits of patients of Contact Lens Clinic, Zagreb University Hospital Department of Ophthalmology, Zagreb, Croatia. During spring of 2010, a survey was conducted in Contact Lens Laboratory, Zagreb University Hospital Department of Ophthalmology, Zagreb, Croatia. 47 completed surveys were collected and analyzed. The results of the...

ed from the full reports. DEFINITION AND CLASSIFICATION OF CLD While clinicians practicing in the area of contact lenses all are familiar with CLD, a variety of terms and verbiage have been used to describe this problem. Typically these patients present with symptoms of ocular discomfort of some sort (e.g., dryness, irritation, discomfort, fatigue, and so forth), and it is common Copyright 2013...

PURPOSE We evaluated the usefulness of commercially available materials for protecting the cornea from drying during vitrectomy with a wide-angle viewing system. METHODS THREE VITREORETINAL SURGEONS EVALUATED FUNDUS VISIBILITY DURING VITRECTOMY ON THE IMAGES OF FIVE STUDY MATERIALS USED ON THE CORNEA: balanced saline solution, a viscoelastic agent, a vitrectomy contact lens, a rigid gas perme...

PURPOSE The purpose of this study was to examine ocular surface and tear film, contact lens, care solution, medical, and patient-related factors that are associated with corneal staining in contact lens wearers. METHODS In this cross-sectional/nested case-control study, in addition to the assessment of corneal staining with fluorescein, a variety of tear film and ocular surface, contact lens,...

purpose : to evaluate the accuracy of the two methods the clinical history method (chm), and the contact lens method (clm), in refractive corneal power determination and comparing the accuracy of srk ii, srk t and holladay ii (h ii) formulas for intraocular lens (iol) power calculation in patients who had laser in situ keratomileusis (lasik) surgery for myopia with or without astigmatism method...

purpose: the impact of photo refractive keratectomy compared with using glasses or contact lens on patient’s quality of life (qol) in myopia. method: in this retrospective cohort study, 102 myopic patient who had undergone prk (at least 6 months ago) and 106 myopic patients using glasses or contact lens were included. changes in vision related qol, uncorrected and best corrected visual acuity (...

CONTEXT Fusarium keratitis is a serious corneal infection, most commonly associated with corneal injury. Beginning in March 2006, the Centers for Disease Control and Prevention received multiple reports of Fusarium keratitis among contact lens wearers. OBJECTIVE To define the specific activities, contact lens hygiene practices, or products associated with this outbreak. DESIGN, SETTING, AND...
