What exactly are the risks for lasik eye surgery?

Some of the risks of lasik eye surgery: over- or under-treatment the inability to wear contact lenses permanent loss of vision reduction in the quality of vision including the development of glare, halos, and starbursts difficulty with night-driving reduced vision in dim lighting conditions. I'm not sure of the exact statistics, but I think it's less than 1% of people who have serious complications. Upwards of 5% of people have less serious complications, the most common of which can be treated. New World iCare offers a LASIK surgery center with ALLEGRETTO WAVE Eye-Q, a 400 Hz ablation rate makes the Eye-Q one of the fastest lasers in the world and its unique PerfectPulse Technology ensures safety and accuracy in combination with outstanding visual results. For added safety, the laser has an extremely fast eye tracker that can respond to any eye movement in just six milliseconds. Previously, only lower-order aberrations (such as nearsightedness, farsightedness, and astigmatism) could be measured and treated either with Glasses, Contacts or Conventional LASIK treatments. Higher-order aberrations, which often linked to the visual glare and halos that cause night vision problems, earlier could not be corrected and that continued to affect quality of vision. With the advent of Wavefront technology and Customized LASIK, however, New World iCare in Mumbai, India have the diagnostic tools to measure 22,000 unique points along the optical pathway to determine and ultimately correct both lower-order and higher-order aberrations. Using the precision provided by the WavePrint map, Customized LASIK has the potential not only to correct how much you see, but also how well you see. Allegretto WaveLight technology also features a unique approach to corneal sculpting. The normal curvature of a healthy cornea is prolate or higher in the center. Most laser systems flatten centrally to create an oblate cornea. This oblate shape causes spherical aberration, which degrades the quality of vision, especially at night, and often produces glare or halos. The Allegretto laser not only treats the cornea centrally, but also peripherally. The laser uses proprietary monograms to adjust the asphericity of the cornea to perform a prolate ablation based on the anterior curvature readings. This prolate curvature, in part, accounts for the excellent quality of vision during the day and night.
