## Abstract

In one aspect, a method is provided herein of marking a patient's eye for reference during a toric lens implantation procedure. The method includes providing an electrocautery device having a handle, a shaft extending from the handle, and a tip defined at the terminus of the shaft. The handle is elongated and extends along a longitudinal axis with the shaft being bent or curved such that the tip is spaced from, and not aligned with, the longitudinal axis. The method further includes using the electrocautery device to cauterize one or more points on the patient's eye, the points being located as reference marks for placement of the toric lens. Advantageously, with the subject invention, a device is used having a bent or curved shaft which may better accommodate the curvature of a patient's eye while marking.

## Claims

### Claim 1

An electrocautery device for marking a patient's eye, the device comprising:
a handle;
a shaft extending from said handle, said shaft having a gauge in the range of 25-27; and,
a conical tip defined at a terminus of said shaft,
wherein, said conical tip being tapered so as to include a tip angle in the range of 60°-120° for forming one or more points of cauterization on the patient's eye, a vertex of said tip angle being centrally located relative to a cross-section of said shaft, and
wherein, said conical tip including an exposed inner conductive wire coinciding with said vertex of said tip angle, an outer tube, and an exposed insulation layer between said inner conductive wire and said outer tube.

### Claim 2 (depends on 1)

An electrocautery device as in claim 1, wherein said gauge is 25.
