A surgical apparatus and surgical techniques for presbyopia correction and other eye disorders such as glaucoma and cataracts by laser removal of the sclera tissue are disclosed. The disclosed preferred embodiments of the system consists of a beam spot controller (3), a fiber delivery unit (4, 5) and a fiber tip (6). The basic laser beam (1) includes UV lasers and infrared lasers having wavelength ranges of (0.15-0.36) microns and (0.5-3.2) microns and diode lasers of about 0.98, 1.5 and 1.9 microns. Presbyopia is treated by a system which uses an ablative laser (1) to ablate the sclera tissue in a predetermined patterns (9) outside the limbus (8) to increase the accommodation of the ciliary body of the eye (7). Both scanning and fiber delivered systems are proposed. The surgery apparatus also includes non-laser device of radio frequency wave, electrode device, bipolar device and plasma assisted device.
