Abstract
Abstract Method and apparatus for manual or semiautomatic computer controlled laser staking of a haptic to an optic of an intraocular lens. An Nd:YAG laser with a HeNe laser aiming beam provides laser power to a fiber optic multiplexer to deliver laser energy to a plurality of staking work stations where the haptics are melted or fused to a lens optic. A fiber optic laser stylus is brought in close proximity with a haptic and optic for application of laser power to fuse or join the haptic to the optic in a cylindrically fused fashion, producing no surface wound and effectively sealing the haptic hole.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
112 words
A staking work station comprising: a. a base; b. an x-y axis positioning table affixed to said base; c. a carousel fixture affixed to said x-y axis positioning table; d. a vertical support post affixed to said base; e. an adjustable lower clamp base attached to said support post; f. a slide bar attached to said lower clamp base; g. a laser stylus attached to said slide bar; h. a pneumatic actuator attached to said vertical support post and said slide bar to move said laser stylus relative to said fixture; and, i. switch means actuated by said slide bar when said laser stylus reaches a predetermined position relative to said carousel.
Claim 2
Dependent Claim
112 words
A staking work station comprising: a. a base; b. an x-y axis positioning table affixed to said base; c. a carousel fixture affixed to said x-y axis positioning table; d. a vertical support post affixed to said base; e. an adjustable lower clamp base attached to said support post; f. a slide bar attached to said lower clamp base; g. a laser stylus attached to said slide bar; h. a pneumatic actuator attached to said vertical support post and said slide bar to move said laser stylus relative to said fixture; and, i. switch means actuated by said slide bar when said laser stylus reaches a predetermined position relative to said carousel.
Claim 3
Dependent Claim
23 words
Staking work station of claim 1 including the use of Nd:YAG laser to affix a haptic to an optic of an intraocular lens.
Claim 4
Dependent Claim
30 words
Staking work station of claim 1 including the use of a Nd:YSG laser focused and concentrated through a micro-optic to affix a haptic to an optic of an intraocular lens.
Claim 5
Dependent Claim
148 words
A laser staking work station comprising: a. a base; b. an x-y axis positioning table on said base including x-y positioning micrometers adjusters; c. brackets on said s-y axis positioning table for clamping a carousel fixture to said x-y positioning table; d. a vertical post mounted centrally on said base for mounting of vertically adjustable upper and lower clamp bases; e. a slide mounted laser arm mounted on said lower clamp base; f. a pneumatic actuating cylinder affixed to said upper clamp base for vertically positioning of a vertically positionable laser arm and a fiber optic laser stylus affixed to a slide bar; g. an L bracket attached to said slide bar; h. a rod attached to said slide bar which contacts a depth stop micrometer; and, i. a switch attached to said lower clamp base which is actuated by said L bracket to activate YAG laser beam.
Claim 6
Dependent Claim
