ABSTRACT:
The invention provides laser-staked intraocular lenses and a method for producing these lenses. The invention method uses a apertureless Nd YAG laser for staking PMMA fixation members onto PMMA lens optic bodies. The resultant laser-staked lenses are free of heat-induced optical deformities and mechanical blemishes and have a strong bond at the junction between the optic body and the fixation member without gaps for the potential accumulation of bio-burden.
