SYSTEMS AND METHODS TREATING FOR CORNEAL ECTATIC DISORDERS

In order to treat corneal ectatic disorders, systems and methods can precisely apply photoactivating light to specified areas of a cornea treated with a cross-linking agent. An example system includes a light source that provides a photoactivating light to photoactivate a cross-linking agent applied to an eye. The system includes optical element(s) that transmit the photoactivating light to the eye according to a pattern defined by a plurality of treatment zones. The treatment zones are delivered to different respective areas on the eye. The plurality of treatment zones includes at least a first treatment zone and a second treatment zone. The first treatment zone provides a first dose of the photoactivating light. The second treatment zone provides a second dose of the photoactivating light. The first dose is greater than the second dose. The first treatment zone is disposed within an inner boundary of the second treatment zone. 为了治疗角膜扩张型疾病，系统和方法可将光活化光精确地施加到利用交联剂处理后的角膜的指定区域。示例系统包括光源，光源提供光活化光来使施加到眼部的交联剂光活化。系统包
