Abstract
Abstract A substantially self-sealing episcleral incision having an approximate central point 1.5 to 3.0 millimeters posterior to the limbus. Portions of the incision extending from the approximate central point extend laterally away from the curvature of the limbus. The configuration of the self-sealing incision allows the incision to seal as the eye is inflated following surgery and therefore requires no sutures for sealing. Accordingly, the probability of astigmatism is eliminated or greatly reduced and the reliance on sutures is eliminated.

Claims Analysis
Total Claims: 33
Claim 1
Independent Claim
61 words
A method of making a substantially self-sealing episcleral incision comprising; providing incision making means; making an incision in the sclera with said means; and said incision having an appropriate central point 1.5 to 3.0 millimeters posterior to the limbus wherein portions of said incision extend away from said approximate central point and extend laterally away from the curvature of said limbus.

Claim 10
Independent Claim
75 words
A method of making a substantially self-sealing episcleral incision comprising: providing incision making means; making an incision in the sclera with said means; and said incision comprising two substantially linear portions joining at an apex 1.5 to 3.0 millimeters posterior to the limbus, said linear portions extending from said apex laterally away from the curvature of said limbus and further, said linear portions having an angle in the range of 80 to 175 degrees therebetween.
Claim 11
Independent Claim
75 words
A method of making a substantially self-sealing episcleral incision comprising: providing incision making means; making an incision in the sclera with said means; and said incision comprising two substantially linear portions joining at an apex 1.5 to 3.0 millimeters posterior to the limbus, said linear portions extending from said apex laterally away from the curvature of said limbus and further, said linear portions having an angle in the range of 80 to 175 degrees therebetween.
Claim 12
Dependent Claim
27 words
