Methods And Apparatus for Treating Keratoconus
First Claim
1. A method of treating keratoconus in an eye of a patient, the method comprising:
- measuring a surface of a cornea of the eye to acquire eye topography data;
based on the eye topography data, selecting a topographic pattern from a plurality of topographic patterns displayed in a graphical user interface;
entering a plurality of vision corrective parameters for the eye of the patient into the graphical user interface;
actuating a processing module associated with the graphical user interface to obtain a surgical plan based on the selected topographic pattern and the plurality of entered vision corrective parameters;
reviewing intrastromal corneal ring segment (ICRS) implantation surgery parameters specified by the surgical plan and displayed in the graphical user interface, wherein the ICRS implantation surgery parameters include specification of at least one ICRS; and
performing implantation surgery of the at least one ICRS into the eye of the patient according to the surgical plan.

Abstract
A method of treating keratoconus in an eye of a patient includes measuring a surface of a cornea of the eye to acquire eye topography data. The method includes, based on the eye topography data, selecting a topographic pattern from topographic patterns displayed in a graphical user interface. The method includes entering vision corrective parameters for the eye of the patient into the graphical user interface. The method includes actuating a processing module to obtain a surgical plan based on the selected topographic pattern and the entered vision corrective parameters. The method includes reviewing intrastromal corneal ring segment (ICRS) implantation surgery parameters specified by the surgical plan and displayed in the user interface. The ICRS implantation surgery parameters include specification of at least one ICRS. The method includes performing implantation surgery of the at least one ICRS into the eye of the patient according to the surgical plan.
