Abstract
Abstract A method for performing endolaser microsurgery on ocular and like tissues utilizing a laser delivery system and an intraocular probe for delivering the laser energy to the tissues comprising the steps of forming an incision in the conjunctiva surrounding the sclera, introducing the probe through the incision, moving the probe anteriorly beneath the conjunctiva to a site remote from the initial incision, and ablating by laser a drainage fistula through the sclera for relieving intraocular pressure.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
76 words
A method for performing endolaser microsurgery on ocular and like tissues utilizing a laser delivery system and an intraocular probe for delivering the laser energy to the tissues comprising the steps of forming an incision in the conjunctiva surrounding the sclera, advancing the probe through the incision, moving the probe anteriorly beneath the conjunctiva to a site remote from the initial incision, and ablating by laser a drainage fistula through the sclera for relieving intraocular pressure.
Claim 2
Independent Claim
76 words
A method for performing endolaser microsurgery on ocular and like tissues utilizing a laser delivery system and an intraocular probe for delivering the laser energy to the tissues comprising the steps of forming an incision in the conjunctiva surrounding the sclera, advancing the probe through the incision, moving the probe anteriorly beneath the conjunctiva to a site remote from the initial incision, and ablating by laser a drainage fistula through the sclera for relieving intraocular pressure.
Claim 3
Dependent Claim
22 words
The method of claim 1 in which said initial incision is formed by the application of pulsed laser energy through said probe.
Claim 4
Dependent Claim
24 words
The method of claim 1 in which said initial incision in the conjunctiva is at a site remote from the sclerostomy or sclerostomy site.
Claim 5
Dependent Claim
18 words
The method of claim 1 and including the additional step of aspirating the ablated tissue through said probe.
Claim 6
Dependent Claim
21 words
The method of claim 3 in which said re-securing step includes suturing the displaced conjunctiva at the site of said incision.
Claim 7
Independent Claim
96 words
A method for performing endolaser microsurgery on ocular and like tissue utilizing a laser delivery system and an intraocular probe for delivering the laser energy to the tissues comprising the steps of forming an incision in the conjunctiva surrounding the sclera, introducing and advancing the probe through the incision, moving the probe anteriorly beneath the conjunctiva to a site remote from the initial incision, and ablating by laser a drainage fistula through the sclera for relieving intraocular pressure, said initial incision in the conjunctive being made at a site remote from the sclerostomy or sclerostomy site.
Claim 8
Independent Claim
96 words
A method for performing endolaser microsurgery on ocular and like tissue utilizing a laser delivery system and an intraocular probe for delivering the laser energy to the tissues comprising the steps of forming an incision in the conjunctiva surrounding the sclera, introducing and advancing the probe through the incision, moving the probe anteriorly beneath the conjunctiva to a site remote from the initial incision, and ablating by laser a drainage fistula through the sclera for relieving intraocular pressure, said initial incision in the conjunctive being made at a site remote from the sclerostomy or sclerostomy site.
Claim 9
Dependent Claim
24 words
A method as defined in claim 6 in which said initial incision is formed by the application of pulsed laser energy through said probe.
Claim 10
Dependent Claim
20 words
A method as defined in claim 6 and including the additional step of aspirating the ablated tissue through said probe.
Claim 11
Independent Claim
93 words
A method for performing endolaser microsurgery on ocular and like tissues utilizing a laser system and an intraocular probe for delivering the laser energy to the tissues comprising the steps of forming an incision in the conjunctiva surrounding the sclera, advancing the probe through the incision, moving the probe anteriorly beneath the connunctiva to a site remote from the initial incision, and ablating by laser a drainage fistula through the sclera for relieving intraocular pressure, said initial incision in the conjunctiva being made at a site remote from the sclerostomy or sclerostomy site.
Claim 12
Independent Claim
93 words
A method for performing endolaser microsurgery on ocular and like tissues utilizing a laser system and an intraocular probe for delivering the laser energy to the tissues comprising the steps of forming an incision in the conjunctiva surrounding the sclera, advancing the probe through the incision, moving the probe anteriorly beneath the connunctiva to a site remote from the initial incision, and ablating by laser a drainage fistula through the sclera for relieving intraocular pressure, said initial incision in the conjunctiva being made at a site remote from the sclerostomy or sclerostomy site.
Claim 13
Dependent Claim
24 words
A method as defined in claim 9 in which said initial incision is formed by the application of pulsed laser energy through said probe.
Claim 14
Dependent Claim
20 words
A method as defined in claim 9 and including the additional step of aspirating the ablated tissue through said probe.
Claim 15
Dependent Claim
23 words
A method as defined in claim 9 in which said re-securing step includes suturing the displaced conjunctiva at the site of said incision.
