Fungal Invasion of Seven Hydrophilic Contact Lenses

American Journal of Ophthalmology, 1993
In six patients we reviewed the clinical, microbiologic, and histopathologic findings of seven hydrophilic contact lenses that had been infiltrated by fungi. Three patients had visual blurring or irritation and redness while wearing a contaminated lens; of these, two were unaware of any lens deposits.

Hydrophilic Contact Lenses*,†

Clinical and Experimental Optometry, 1966
SUMMARY It has been the author's experience both in Harrisburg, Pennsylvania, and Prague, Czechoslovakia, to see a number of patients wearing this lens who report complete comfort. Some patients reported a total unawareness of the presence of a lens in the eye. Visual acuity was a problem with the older hydrophilic lenses, apparently not the new.

Computer‐aided design of hydrophilic contact lenses

Clinical and Experimental Optometry, 1986
This paper discusses the problems of visualizing new contact lens designs. We have developed computer-aided design (CAD) software that greatly improves lens visualization: this is illustrated for a spherical hydrophilic lens. Designers have the options of displaying magnified cross-sections of any part of the lens, making detailed measurements of these

HYDROPHILIC CONTACT LENSES IN CORNEAL DISORDERS

Acta Ophthalmologica, 1984
Hydrophilic ‘bandage’ lenses were fitted in 107 patients with corneal disorders not satisfactorily responding to conventional medical treatment. An over‐all beneficial effect on both ocular discomfort, visual acuity and corneal disorder was found (P < 0.002).

Visual Performance with Soft Hydrophilic Contact Lenses

Optometry and Vision Science, 1985
An instability of the visual correction is sometimes associated with soft hydrophilic contact lenses. However, this problem does not seem to have detracted from the commercial success of this form of refractive aid. To facilitate the quantification of visual performance during soft lens wear, a televised test system was developed and has been fully ...

Hydrogen Peroxide Sterilization of Hydrophilic Contact Lenses

Archives of Ophthalmology, 1975
A new, simple, and effective procedure for the sterilization of soft contact lenses utilizes hydrogen peroxide, an inexpensive and readily availiable solution.

Problem Analysis With Hydrophilic Contact Lenses

Clinical and Experimental Optometry, 1972
The introduction of Griffin Bionite hydrophilic and hygroscopic contact lenses to Australian practitioners, for use in the first open market in the world, occurred in July, 1970. Intensive clinical research, under close supervision of United States F.D.A.

Bacterial adhesion to surface hydrophilic and hydrophobic contact lenses

Biomaterials, 2001
The aim of this paper was to determine the adhesion of two physico-chemically characterized bacterial strains to a surface hydrophilic (CL A, water contact angle 57 degrees) and hydrophobic (CL B, water contact angle 106 degrees) hydrogel contact lens (CL) with and without an adsorbed tear film in a parallel plate flow chamber. Hydrophobicity (by water

Fungal growth in hydrophilic contact lenses

International Contact Lens Clinic, 2000
Abstract Fungal colonization of 330 hydrophilic contact lenses obtained from wearers was investigated. In vitro cultures from lens care solutions and observations by optical and scanning electron microscopy (SEM) of lenses were used to study the morphology of the fungal colonies, identify the invading fungi taxonomically, and investigate fungal ...

Measured and Laboratory-Stated Parameters of Hydrophilic Contact Lenses

Optometry and Vision Science, 1977
One hundred thirty-one new hydrophilic lenses made by 3 manufacturers were randomly selected from an optometry clinic for measurement and inspection. Approximately 60% of the base-curve specifications fell within the following ranges for the measured dimensions: Bausch & Lomb Soflens contact lenses, less than 0.150 mm; Milton Roy Naturvue lenses, less ...
