INTRODUCTION We have developed a suction-assisted one-piece self-retaining wide-angle contact lens for vitrectomy. DESIGN The wide-angle contact lens is a one-piece lens without the case, making it lightweight. The contact inferior surface is enhanced by four quadrant plate extensions. A metal housing is attached to the side of the plate extension with an opening at the inferior surface. A ne...

BACKGROUND To evaluate wide-field laser ophthalmoscopy (Optomap 200Tx) for screening retinal lesions before myopic refractive surgery. METHODS Seventy-eight eyes of 78 consecutive refractive surgery candidates were included in this study. All subjects underwent Optomap 200Tx, mydriatic slit-lamp lens examination and the Goldmann three-mirror contact lens examination, which was considered as t...

in view of the rapid expansion of contact lens amongst the users, new dimensions have been added to the domain of ophthalmology: giant papillay conjunctivitis, a disease caused by different kinds of contact lens, appears weeks or months after they are used, although some patients are struck years later. the predominant symptoms are increased awareness of lenses, ocular itching, blurred vision a...

PURPOSE To evaluate ocular response and subject acceptance of a new multipurpose disinfecting solution (MPDS), Complete Revitalens (RevitaLens OcuTec in the US Market), for soft contact lens care in a large "real practice" setting. METHOD This is an international multi-center, open-label assessment carried out in 10 countries across Europe and in the USA. Up to 10 subjects who were currently ...

introduction: some fungi such as aspergillus, alternaria, cladosporium and fuzadium can peneterate matrix of contact lens. alternaria is a saprop and a pathogen in plants which is rarely seen in human being. this paper reported one case of contact lens contamination with alternaria in human. case report: the patient is a 24 year old woman who had used contact lens for 7 months. since she was on...

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 (...

In this paper we develop a method for studying tight contact structures on lens spaces. We then derive uniqueness and non-existence statements for tight contact structures with certain (half) Euler classes on lens spaces.

OBJECTIVE To investigate the effect of storage temperature on the ability of contact lens solutions to inhibit growth of Fusarium species. A 2006 Food and Drug Administration inspection of Bausch & Lomb's Greenville, South Carolina, manufacturing site indicated that Bausch & Lomb failed to regulate storage and transport temperatures of their products. METHODS Six contact lens solutions were s...
