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 ...

Problem Analysis With Hydrophilic Contact Lenses
Clinical and Experimental Optometry, 1972The 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, 2001The 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, 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 ...

Measured and Laboratory-Stated Parameters of Hydrophilic Contact Lenses
Optometry and Vision Science, 1977One 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 ...

Hydrophilic Contact Lenses For Correcting Irregular and High Astigmatism
Archives of Ophthalmology, 1972Fifty eyes with either advanced keratoconus (17), recent corneal transplants (20), or high astigmatism (13) were fitted with soft hydrophilic contact lenses. In all eyes, spectacle correction did not allow for reasonable visual acuity, and hard contact lenses were either intolerable, dangerous to the underlying ocular pathological condition, or did not

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.

Contribution of regimen steps to disinfection of hydrophilic contact lenses
Contact Lens and Anterior Eye, 2004The effect of regimen steps on overall performance of contact lens disinfection processes was evaluated. Hydrophilic lenses were inoculated with Staphylococcus aureus, Pseudomonas aeruginosa, Serratia marcescens, Candida albicans, or Fusarium solani. Contributions of regimen steps and rinse volumes to disinfection abilities of OPTI-FREE EXPRESS, Solo ...
