LASER-ASSISTED THERMAL SEPARATION OF TISSUE

摘要

A laser-assisted method for fully or partially separating tissue such as collagen containing tissue is provided. In one embodiment, the method pertains to a capsulorhexis whereby the laser-assisted method is applied to the lens capsule. A light-absorbing agent is added into or onto the tissue. A light beam with a wavelength capable of being absorbed by the light absorbing agent is then directed at the tissue to cause a thermal effect at the tissue following a predetermined closed curve with the goal to avoid irregularity or potential tears in the resulting rim of the tissue.

主权项

1. A device for treating tissue in the anterior lens capsule of an eye, the device comprising:
a laser device programmed to direct a treatment laser beam along a predetermined closed curve on the anterior lens capsule in a single pass starting at an initial point interior to the closed curve, then along the closed curve, and then to a final point interior to the closed curve.
