ABSTRACT:
A technique is described for liquefying, or gelifying, a hardened, cataractous lens nucleus and aspirating the same. Heat or heated solution is delivered to the lens nucleus in vivo so that the heat or heated solution is placed in contact with the hardened nucleus in order to heat and liquefy the same. The lens nucleus is irrigated simultaneously with a cooled solution to thereby limit to a very small area where the heat or heated solution is present in the eye. This allows the surgeon precise control over which intraocular anterior segment structures are exposed to the heat or heated solution. The liquefied lens nuclear material is then aspirated from the eye. The above allows the removal of a lens nucleus through a 1 to 2 mm corneal or limbal incision which is smaller than the smallest incision allowable with previously known small incision cataract techniques. The above benefits the patient as it allows small incision cataract removal to be done in a way that is non-traumatic to intraocular structures. The above benefits the surgeon, and the patient, in that it is a relatively straightforward and easy surgical maneuver for the surgeon to perform. This is in stark contrast to current phacoemulsification, which is potentially very traumatic to intraocular structures, and which is a relatively difficult surgical maneuver to perform.
