Regardless of whether the surgeon does LASIK or surface ablation, there is an additional choice in “how” the laser will be applied to the cornea. Conventional ablations make use of data obtained during manifest and cycloplegic refractions. This data, that is generated by humans (surgeon, technician etc) based on their examination of your eye, is what tells the laser how much to treat and how to treat. The ablation profile will contain a spherical component and an astigmatic component. Conventional ablations essentially treat what glasses have been treating for hundreds of years. Wavefront-guided treatments allow optical properties beyond spherical and cylindrical defocus to be corrected. Wavefront aberrometers (automated machines) capture data that describe the optical aberrations of a patient’s eye. This data, that is generated by an automated machine (wavefront aberrometer) based on an average of 3 automated recordings, is what tells the laser how much to treat and how to treat.
Whether the additional information obtained with wavefront-guided treatments is translated into better ablations and improved acuity compared with conventional LASIK can be determined by comparing the FDA trials data. In wavefront-guided LASIK, 89% of patients achieved uncorrected visual acuities of 20/20 or better . By contrast, with conventional treatment, patients reached 20/20 or better only 72% of the time. Therefore more people can expect to achieve uncorrected vision of 20/20 with wavefront-guided LASIK. The likely reason for this difference is that wavefront-guided treatments treat higher order aberrations as well (conventional treatments do not treat higher order aberrations).
Not sure about wavefront laser eye surgery, but LASIK eye surgery is generally considered to be a safe and effective method of treating near-sightedness, far-sightedness, and astigmatism and millions of people undergo this procedure every year throughout the world.
No surgery is without risks or complications, however, and this must be understood and accepted before making the decision.
The most common side effects of LASIK eye surgery are dry eyes and glare. The incidence of these are debated between proponents and opponents of the surgery. The FDA considers the risks to be low enough to approve the technology required for LASIK (microkeratomes, excimer lasers, etc.)
Safety can be increased by selecting a skilled surgeon using the best technology. Studies show that experience is one of the most important factors in selecting a surgeon.
There is a good San Diego Lasik website. It has lots of info and some very informative Lasik articles.
