HYDROPHILIC CONTACT LENSES

Archives of Ophthalmology, 1969
To the Editor. —Bausch and Lomb Inc., are soon to release their hydrophilic contact lens, known as SOFLENS, on the market. I have been working with these lenses for the last year and have been fitting them on selected patients since July 1968. As there is little information yet available on this new lens, which is very different from the conventional ...

Hydrophilic Contact Lenses in Corneal Disease

Archives of Ophthalmology, 1971
A series of six patients illustrates that a hydrophilic contact lens may be fitted upon an edematous corneal epithelium containing bullae. The lens is well tolerated and may be worn continuously for prolonged periods without adverse effects. The lens produces a rapid and dramatic relief of pain and the accompanying symptoms of chronic bullous ...

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

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.

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).

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.

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 ...
