Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
83 words
A method for treating subretinal neovascular disease with a laser comprising: anesthetizing the eyeball; preparing the surgical field; introducing a fiberoptic probe behind the eyeball; visualizing the subretinal neovascular complex through one of a slit lamp, operating microscope, or indirect ophthalmoscope; positioning the probe tip relative to the subretinal neovascular complex; activating the laser energy; focusing the laser energy on the subretinal neovascular complex; obliterating the subretinal neovascular complex with the laser energy; and withdrawing the fiberoptic probe from behind the patient's eye.
Claim 2
Independent Claim
83 words
A method for treating subretinal neovascular disease with a laser comprising: anesthetizing the eyeball; preparing the surgical field; introducing a fiberoptic probe behind the eyeball; visualizing the subretinal neovascular complex through one of a slit lamp, operating microscope, or indirect ophthalmoscope; positioning the probe tip relative to the subretinal neovascular complex; activating the laser energy; focusing the laser energy on the subretinal neovascular complex; obliterating the subretinal neovascular complex with the laser energy; and withdrawing the fiberoptic probe from behind the patient's eye.
Claim 3
Dependent Claim
25 words
The method of claim 1 wherein the fiberoptic probe is curved in shape thereby allowing the placing of the probe tip behind the posterior sclera.
Claim 4
Dependent Claim
25 words
The method of claim 1 wherein placing the fiberoptic probe behind the eyeball further comprises placing the fiberoptic probe tip in contact with the sclera.
Claim 5
Dependent Claim
21 words
The method of claim 2 wherein placing the fiberoptic probe further comprises placing a quartz fiberoptic probe for transmitting laser energy.
Claim 6
Dependent Claim
25 words
The method of claim 1 wherein activating laser energy further comprises the activating laser energy of a wave-length sufficient to be transmitted by the sclera.
Claim 7
Dependent Claim
22 words
The method of claim 5 wherein the wave length transmitted by the sclera further comprises emitting a wave length approximately 1064 NM.
Claim 8
Dependent Claim
20 words
The method of claim 1 wherein the fiberoptic laser probe tip is convexed and semi-circular for delivering the energy transsclerally.
Claim 9
Dependent Claim
19 words
The method of claim 7 wherein the fiberoptic probe tip further comprises a saphire tip for delivering energy transsclerally.
Claim 10
Independent Claim
78 words
A method for photocoagulating subretinal neovascularization comprising: preparing the eyeball for the procedure; introducing a fiberoptic probe behind the eyeball; visualizing the subretinal neovascular complex through one of a slit lamp, operating microscope, or indirect ophthalmoscope; placing the fiberoptic probe tip against the sclera relative to the subretinal neovascular complex; activating the laser; concentrating the laser energy on the subretinal neovascular complex; obliterating the subretinal neovascular complex with laser energy; and withdrawing the laser probe from the patient.
Claim 11
Independent Claim
78 words
A method for photocoagulating subretinal neovascularization comprising: preparing the eyeball for the procedure; introducing a fiberoptic probe behind the eyeball; visualizing the subretinal neovascular complex through one of a slit lamp, operating microscope, or indirect ophthalmoscope; placing the fiberoptic probe tip against the sclera relative to the subretinal neovascular complex; activating the laser; concentrating the laser energy on the subretinal neovascular complex; obliterating the subretinal neovascular complex with laser energy; and withdrawing the laser probe from the patient.
Claim 12
Dependent Claim
24 words
The method of claim 9 wherein the placing of the probe tip against the sclera further comprises the placing of a convex, saphire tip.
Claim 13
Dependent Claim
25 words
The method of claim 9 wherein the activating of the laser energy further comprises activating laser energy of a wave length of approximately 1065 NM.
Claim 14
Dependent Claim
20 words
The method of claim 9 wherein the introducing of the fiberoptic probe further comprises introducing a quartz fiberoptic bearing probe.
