MICROBIOLOGY AND HYDROPHILIC CONTACT LENSES

Optometry and Vision Science, 1971
ABSTRACT Contact lenses made of poly (2‐hydroxyethyl methacrylate) are capable of autoclaving and repeated exposure to steam or boiling water. These procedures are effective methods of maintaining the microbiological safety of hydrophilic contact lenses on the shelf and while being worn by ...

Hydrophilic Contact Lenses*,†

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.

Visual Performance with Soft Hydrophilic Contact Lenses

Optometry and Vision Science, 1985
An 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 DISORDERS

Acta Ophthalmologica, 1984
Hydrophilic ‘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).

Fungal Invasion of Seven Hydrophilic Contact Lenses

American Journal of Ophthalmology, 1993
In 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.

TWO YEARS EXPERIENCE WITH HYDROPHILIC CONTACT LENSES

Optometry and Vision Science, 1970
ABSTRACT Three years of study, research and development have been devoted toward the improvement of hydrophilic contact lenses originally developed in Czechoslovakia. Patients have been part of this program since September 1967.

Hydrophilic Contact Lenses in Corneal Disease

Archives of Ophthalmology, 1971
A 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, 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.

Hydrogen Peroxide Sterilization of Hydrophilic Contact Lenses

Archives of Ophthalmology, 1975
A 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, 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.
