PENETRATION OF HYDROPHILIC CONTACT LENSES BY ASPERGILLUS FUMAGATUS

American journal of optometry and archives of American Academy of Optometry, 1973
ABSTRACT The susceptibility of a hydrophilic lens surface and interior to microbiological degradation was tested, and precautionary measures in relation to clinical conditions are suggested.

Computer‐aided design of hydrophilic contact lenses

Australasian journal of optometry, The, 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

THE FLUID CONTENT OF HYDROPHILIC CONTACT LENSES ON THE EYE

Acta Ophthalmologica, 1983
Hydroflex m, Hydroflex 72 and Saufion PW lenses were tested (declared fluid content 38.4%, 72% and 79%, respectively). At room temperature in vitro the mean fluid content of Hydroflex m and Saufion PW was significantly higher than declared (P < 0.002), but this might be due to insufficient blotting of the lens surface.

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 ...

[Hydrophilic contact lenses and pathogenic microorganisms].

Journal francais d'ophtalmologie, 1987
A first study was conducted on 243 hydrophilic contact lenses: 65 were macroscopically abnormal and 100 were infected with fungi. Moreover on Sabouraud's medium with chloramphenicol, 30 bacterial strains were isolated of which 25 Pseudomonas sp. (10 Ps. cepacia) and 1 Serratia liquefaciens.

The Appraisal of the Problems of Hydrophilic Contact Lenses

Clinical and Experimental Optometry, 1965
Disadvantages in the use of hydrophilic gel lens have led to experiments with silicone and semi-permeable lenses. The writer hopes that they may overcome some of the problems inherent in the hydrophilic lens.

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.

Iodine disinfection of hydrophilic contact lenses.

Annals of ophthalmology, 1981
A simple and effective technique for disinfecting hydrophilic contact lenses uses a saturated solution of molecular iodine in water. This technique has disinfected lenses that were incubated in actively growing cultures of bacteria and fungi in concentrations of 10(7) to 10(8) organisms per ml. Ocular tolerance studies showed that lenses disinfected by
