Abstract
Presbyopia is treated by a method which uses various lasers to remove a portion of the scleral tissue and increase the accommodation of the presbyopic patient's eye. Stable accommodation is achieved by the filling of the sub-conjunctival tissue to the laser-ablated scleral areas. The proposed laser wavelength ranges from ultraviolet to infrared of (0.15-0.36) microns, (0.5-1.4) microns and (0.9-10.6) microns. Both scanning and fiber delivered systems are proposed.

A laser beam ophthalmic surgery method for treating presbyopic patient by removing a portion of the scleral tissue of an eye in a predetermined pattern and area, whereby the accommodation of the presbyopic eye increases via the movement of the ciliary body and zonular fiber connected to the lens of the eye, the predetermined pattern having a depth of about (60%-90%) of a scleral tissue thickness.
