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 ...

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.

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

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 ...

Imaging surfaces of hydrophilic contact lenses with the atomic force microscope
Biomaterials, 1993Soft contact lens (SCL) surfaces were imaged with atomic force microscopy (AFM). High-resolution images of unworn SCL were obtained under nearly physiological medium. We present images of surfaces of collagen bandage lens under dry or aqueous conditions and of SCL of different water content and fabrication processes.

Eyeblink activity with hydrophilic contact lenses
Acta Ophthalmologica, 1988Abstract A televised discrimination task was used to assess visual performance with spectacles and then with hydrophilic (‘soft’) contact lenses in a small group of human subjects. Concurrent recording of eyeblink activity indicated that an increased blink rate recorded during the first month of soft contact lens wear was confined to the immediate post‐

A Study of the Reproducibility of Spin Cast Hydrophilic Contact Lenses
Clinical and Experimental Optometry, 1976A study was conducted using ten existing contact lens patients over a period of 10 weeks. This involved 200 lens changes to test the reproduclbility of spin cast hydro‐philic contact lenses to obje...
