Abstract

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.

Claims (11)

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.

2. The method of claim 1 , further comprising collecting the anatomical information using an aberrometer.

3. The method of claim 1 , the calculating the laser ablation pattern further comprising:

calculating the laser ablation pattern using the anatomical information of the eye, the measured configuration, and wavefront data of the cornea.

4. The method of claim 3 , further comprising calculating an ablation profile using the wavefront data of the cornea.

5. The method of claim 1 , wherein the corneal flap configuration comprises a flap geometry.

6. The method of claim 1 , further comprising making a reference mark on the corneal flap used to track a corneal position during the laser surgery.
