HYDROPHILIC CONTACT LENSES IN CORNEAL DISORDERS
Acta Ophthalmologica, 1984Hydrophilic ‘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, 1985An 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 ...

Hydrophilic Contact Lenses in Corneal Disease
Archives of Ophthalmology, 1971A 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 ...

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

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

THE FLUID CONTENT OF HYDROPHILIC CONTACT LENSES ON THE EYE
Acta Ophthalmologica, 1983Hydroflex 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, 2000Abstract 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, 1987A 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, 1965Disadvantages 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.
