Microwave Sterilization of Hydrophilic Contact Lenses
American Journal of Ophthalmology, 1986We used standard 2,450-MHz microwave irradiation to achieve sterilization of hydrophilic contact lenses contaminated with a variety of bacterial, fungal, and viral corneal pathogens. A three-dimensional rotisserie was used to overcome the problem of "cold spots" within the microwave oven.

Continuous Wear of Hydrophilic Contact Lenses
Archives of Ophthalmology, 1973A hydrophilic contact lens was fitted on the normal right cornea of ten informed volunteers and worn continuously for ten days. No evidence of an overwearing syndrome was encountered in any of the subjects. Edema and a burning sensation occurred in several subjects, but these symptoms were transient, minor, and self-limited.

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 ...

Fungal Invasion of Seven Hydrophilic Contact Lenses
American Journal of Ophthalmology, 1993In 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.

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, 1986This 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
