摘要：
A method of forming edges on contact lenses prepared from laser-machinable, organic polymers wherein the edge is formed by contacting the lens with a laser beam having a wavelength which is absorbed by the polymer. The radiated energy supplied to the polymer by the laser beam is such that the ratio of heat absorbed in vaporization of the polymer to heat absorbed by the polymer bulk is maximized.
