A method and apparatus are provided to increase the accuracy and safety of ablative laser treatments of the eye. In an illustrative embodiment, tissue is removed from the cornea, via a laser, to provide an effluent from the cornea. The effluent is aspirated and deposited into a chemical analyzer. The amount of effluent that has been deposited is quantitated. Data relating to a dimension of the ablated cornea is inputted to a computer and data relating to the quantitized effluent is also inputted to the computer. The computer uses the quantitized effluent data and the inputted dimension data to estimate the number of diopters of treatment accomplished. The estimated number of diopters of treatment accomplished is compared to a desired number of diopters of treatment and the laser treatment is modified based on the comparison for most accurate optical results.

A novel method and apparatus are provided for correcting an off-center laser ablation in the cornea, in which the original ablated area has a center that is offset from the correct center of the optical cornea. The method comprises the steps of determining the correct optical center of the cornea and the offset location of the ablation; performing a supplemental laser ablation on the cornea with the laser beam covering generally the original ablated area, and with the energy of the supplemental laser increasing in a direction from the offset center toward the correct center; introducing a laser shield to cover the entire original ablated area; and performing another laser ablation with the correct optical center as the center of the ablated area.

The surgical instrument apparatus emits a narrow beam of light that exits a point on the blade. The light crosses in front of the blade at a point predetermined by the surgeon. The light is reflected off the Descemet's membrane when the tip of the blade reaches the proper depth and bounces back into an entrance point on the blade. The reflected light is received by a light sensor that is coupled to a transmitter. The transmitter sends a signal to a receiver coupled to a tone generator. When the tone is generated, the surgeon knows that the incision has reached the proper depth.

A UV-mask for treating keratoconus. The UV-mask could be made by having an image representing a surface of the patient's cornea with a topography map indicating an area of abnormal corneal thickness. The image is printed onto a sheet. The sheet is cut on or around the area of abnormal corneal thickness to create a transparent window in the sheet. The sheet is further cut on or around the corneal surface to result in a UV-mask. Also disclosed is a UV-mask for use in UV-irradiation treatment of keratoconus. Also disclosed are methods of treating keratoconus in an eye of a patient using a UV-mask.
