Are there differences in lasers used for LASIK?
Yes and no. All lasers utilized for LASIK deliver 193 nanometers of ultraviolet light. How that ultraviolet light is delivered helps to differentiate various lasers. There is a trend towards smaller spots, wider treatment areas, and tracking devices to help monitor eye movement during the procedures. Each laser company will attest to their laser’s superiority. What is more important, is your surgeon’s confidence in the reproducibility of results, the reliability of the laser, and the surgeon’s own nomogram based on that laser’s results. A nomogram is a program that a surgeon uses to enter a treatment plan based on historical data of clinical results for certain age groups and refractive errors. Vision Correction Centers monitor their results on an ongoing basis and make appropriate changes in their nomogram as deemed necessary. It is at this time, a highly refined tool.
