A method for changing the shape of the cornea of an eye to correct refractive disorders comprises employing laser radiation having a selected wavelength, beam pattern, and beam power profile, and employing this radiation for a selected time duration, wherein the wavelength, beam pattern, beam power profile and time duration are chosen to selectively kill or injure keratocytes and to avoid shrinking the collagen in a selected treatment volume of the cornea which has a posterior boundary which is at least 10% of the total stromal depth, and preferably between 50-90% of the stromal depth.

Method for correcting refractive disorders

A laser system applies energy of the proper wavelength to the cornea of the eye and the stroma of the cornea is thereby heated and changes permanently, causing the shape of the cornea to change. Laser treatment patterns are disclosed for correcting nearsightedness, farsightedness and astigmatisms.

Correction of the optical focusing system of the eye using laser thermal

An intraocular lens assembly for implantation into a posterior eye chamber is provided having a central lens and an outer ring interconnected therewith. The assembly when implanted is operatively engaged by the ciliary muscle of the eye which causes changes in the focusing power of the lens in order to achieve accommodation.
