Abstract
Abstract A laser may be used to soften the cataractous tissue prior to removal with the wedge-tipped probe. The cataract softening or other laser energy used during the surgical procedure being performed may be delivered through the operating microscope. In the case of cataract softening, when the laser is so delivered, no delay is required between cataract softening and cataract removal.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
120 words
A method of applying a laser one of to and into an eye during ophthalmic surgery comprising: providing an operating microscope on a support structure; mounting means for producing laser light to one of said operating microscope and said support; generating a beam of laser light with said means for producing laser light; directing said laser light from said source of laser light through said operating microscope; providing a hand-held probe and a fiber optic cable for conducting said laser light to said hand-held probe, said fiber optic cable being operatively coupled to said hand-held probe and being operatively coupled to one of said source of laser light and said operating microscope; and impinging said laser light upon an eye.
Claim 2
Independent Claim
120 words
A method of applying a laser one of to and into an eye during ophthalmic surgery comprising: providing an operating microscope on a support structure; mounting means for producing laser light to one of said operating microscope and said support; generating a beam of laser light with said means for producing laser light; directing said laser light from said source of laser light through said operating microscope; providing a hand-held probe and a fiber optic cable for conducting said laser light to said hand-held probe, said fiber optic cable being operatively coupled to said hand-held probe and being operatively coupled to one of said source of laser light and said operating microscope; and impinging said laser light upon an eye.
Claim 3
Dependent Claim
