Laser corneal flap cutting system and associated methods

摘要

A method for performing wavefront-guided laser surgery on a cornea includes the step of calculating a corneal flap configuration based upon collected anatomical information on an eye and wavefront data on a cornea of the eye. Such data may be collected by, for example, an aberrometer, although this is not intended as a limitation. The calculated configuration is transmitted to a processor in controlling relation to a corneal flap-cutting device. The flap-cutting device is used to create a corneal flap based upon the calculated configuration. A system for performing wavefront-guided laser surgery on a cornea includes a processor for receiving the anatomical information and wavefront data. A software package is adapted to calculate the corneal flap configuration and to control a conical flap-cutting device to cut a corneal flap commensurate with the calculated corneal flap configuration.

主权项

1. A method for performing laser surgery comprising:
measuring, by an aberrometer, a configuration of a corneal flap created by a femtosecond laser in a cornea of an eye; transmitting, by athe aberrometer, the measured configuration of the created corneal flap to a processor; calculating, by the processor, a laser ablation pattern for the eye using anatomical information of the eye and the measured configuration of the flap created in the cornea of the eye; and controlling, by the processor, a treatment laser to create the laser ablation pattern in the cornea.
