PHOTODISRUPTIVE LASER TREATMENT OF THE CRYSTALLINE LENS

Title:

PHOTODISRUPTIVE LASER TREATMENT OF THE CRYSTALLINE LENS

Document Type and Number:

WIPO Patent Application WO/2010/075571

Kind Code:

A3

Abstract:

Apparatus and methods of treating a hard lens region of an eye with a laser where one method includes identifying a boundary of the hard lens region, selecting a laser-parameter to enable a photodisruptive procedure in the hard lens region and to control a spreading of bubbles in the hard lens region, modifying a mechanical property of a posterior portion of the hard lens region in a proximity of the identified boundary by the photodisruptive procedure, and modifying a mechanical property of a portion anterior to the modified posterior portion of the hard lens region by the photodisruptive procedure. The laser bubbles can be applied to form incisions which are non transverse to an axis of the eye and intersect the lens fibers.
