摘要：
Optical lens bodies and haptics therefore are prepared from polymeric materials wherein all surfaces of the materials are substantially biologically inert to occular tissue, all surfaces are substantially free of surface defects when viewed through a 10 power optical microscope, the materials have a contact angle with water of at least 85.degree., a contact angle with glycerol of least 75.degree. and a surface energy less than 30 erg/cm.sup.2.
