APPARATUS FOR TREATING PRESBYOPIA

摘要

An apparatus and method are disclosed for treating near vision loss or deficiency, such as presbyopia. In contrast to conventional techniques, a peripheral ablation is provided in an annular zone of the cornea ranging from 5.5 to about 10+mm to increase the dioptic power of this peripheral zone. The central zone disposed within the peripheral zone of the cornea is left untreated, is corrected for other vision deficiencies or is corrected so that it reverts to its characteristics prior to the peripheral ablation.
