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...

OBJECTIVES To evaluate success rates in the correction of astigmatism with toric and spherical soft contact lens fitting. METHODS 30 patients with soft toric lenses having more than 1.25 D of corneal astigmatism (25 eyes; Group A) or having 0.75-1.25 D of corneal astigmatism (22 eyes; Group B) and 30 patients with soft spheric lenses having 0.75-1.25 D of corneal astigmatism (28 eyes; Group C...

Identity ofthe causative organism was confirmed by moderate growth ofan organism from the corneal scrapings on one solid medium, growth of the same organism in more than one liquid medium, or growth in one liquid medium that correlated with the Gram stain. *Soft contact lenses (all cosmetic daily and extended wear). tHard contact lenses (aphakia and keratoconus, daily wear). tTherapeutic contac...

PURPOSE To assess the disinfection efficacy of multipurpose solutions (MPS) against different bacterial species adhered either to silicon hydrogel or to conventional hydrogel contact lenses (CLs). The influences of the MPS formulation and the chemical composition of the lens material were investigated. METHODS This investigation followed the standard 14729, which establishes the guidelines fo...

Iris is one of the most promising biometric modalities, and is in usual use in enormously large-scale applications. The presences of a contact lens, mainly a textured cosmetic lens, create a challenge to iris recognition as it obfuscates the natural iris patterns. Earlier work used novel lens detection algorithm with Modified Local Binary Pattern analysis (MLBP) features to produce feature valu...
