ABSTRACT:
An improved method of ophthalmological surgery is disclosed. The method is used to change the optical characteristics of an eye through subjecting the eye's cornea to ultraviolet irradiation thereby volumetrically removing corneal tissue by way of photoablative decomposition. The method comprises the further step of subjecting a central portion of the cornea to increased ultraviolet irradiation and photoablative decomposition, over and above the irradiation of other corneal tissue. The effect is an increase in qualitative visual results while not significantly changing the refractive characteristic of the cornea.
