Corneal-thickness response to ultra-thin Bausch & Lomb Soflens (polymacon) contact lenses.
A study was conducted to test the hypothesis that a more favorable corneal-edema response for hard-to-fit patients might be expected from ultra-thin Bausch & Lomb Soflens (polymacon) contact lenses than from standard-thickness lenses because of the additional oxygen reportedly available to the cornea. Corneal edema was monitored by measuring changes in corneal thickness over 6 hr of lens wear with an electronic pachometry assembly. Statistical analysis showed significantly less edema for a group of hard-to-fit patients wearing ultra-thin lenses than for a group of successful patients fitted with standard-thickness lenses.
