12/01/1985 - "All lenses were made to the Syntex specifications for the Polycon lens and the groups were comparable with regard to age, sex, refractive error, corneal astigmatism, and any pre-existing ocular pathology. "
11/01/1982 - "Both flexure and induced residual astigmatism increased as center thickness decreased, and were greater than with PMMA or Polycon lenses of similar dimensions. "
03/01/1982 - "Our results indicate that Polycon lenses undergo significantly more flexure and alter residual astigmatism more on toric corneas than PMMA lenses at all center thicknesses evaluated. "
03/01/1982 - "Flexure and residual astigmatism with Polycon and polymethyl methacrylate lenses on toric corneas."
03/01/1982 - "The present study was designed to evaluate the flexure and residual astigmatism of gas permeable Polycon contact lenses on toric corneas and compare the results with those obtained with PMMA lenses on the same corneas. "

04/01/1979 - "Lenses were worn in a double-masked and random sequence for periods of 6 hr. Patients developed less corneal edema with Polycon lenses than with PMMA lenses. "
03/01/1980 - "An evaluation was made of the incidence of corneal edema with polymethylmethacrylate (PMMA) contact lenses and Polycon (silafocon A) lenses of identical design. "
04/01/1977 - "Forty-six patients who were unable to wear polymethylmethacrylate (PMMA) contact lenses, owing mainly to corneal edema and associated symptoms, were fitted with gas-permeable hard Polycon lenses of the same dimensions. "
04/01/1979 - "Steeper-fitting PMMA and BP Flex lenses produced more corneal edema than optimum-fitting lenses made of the same materials, while steeper-fitting Polycon lenses produced only slightly more edema than the optimum-fitting Polycon lenses."
04/01/1979 - "Those patients who developed little corneal edema with optimum-fitting PMMA lenses also developed little edema with the BP Flex and Polycon lenses. "

04/01/1977 - "None of the 46 patients exhibited observable edema with the POLYCON lenses. "
03/01/1980 - "Edema occurred significantly more frequently with PMMA than with Polycon lenses."
04/01/1979 - "Steeper-fitting PMMA and BP Flex lenses produced more corneal edema than optimum-fitting lenses made of the same materials, while steeper-fitting Polycon lenses produced only slightly more edema than the optimum-fitting Polycon lenses."
04/01/1979 - "Those patients who developed little corneal edema with optimum-fitting PMMA lenses also developed little edema with the BP Flex and Polycon lenses. "

01/01/1986 - "Fitting polycon lenses in keratoconus."
01/01/1983 - "Long-term wear of Polycon contact lenses in keratoconus."

12/01/1985 - "All lenses were made to the Syntex specifications for the Polycon lens and the groups were comparable with regard to age, sex, refractive error, corneal astigmatism, and any pre-existing ocular pathology. "
