Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
55 words
An eye restraining device, comprising: means adapted to be secured against the sclera of an eye for positioning and aligning the eye, said positioning and aligning means being a ring-shaped means adapted to be in contact with the sclera of the eye for causing the cornea of the eye to project above the ring-shaped means.
Claim 2
Dependent Claim
55 words
An eye restraining device, comprising: means adapted to be secured against the sclera of an eye for positioning and aligning the eye, said positioning and aligning means being a ring-shaped means adapted to be in contact with the sclera of the eye for causing the cornea of the eye to project above the ring-shaped means.
Claim 3
Dependent Claim
31 words
