Over the past few centuries eyesight correction has been evolving. Eyeglasses, which have been tested by centuries of use, were only the beginning. Then came contact lenses which provided a more fashionable look. A couple decades ago, surgical eyesight correction was developed, providing people with a more permanent solution. The most popular method of performing eye surgery is called LASIK, which stands for laser-assisted in situ keratomileusis. LASIK San Francisco uses lasers to change the shape of the front part of your eye that does most of the focusing in your eyes. This part of your eye is called the cornea. Using lasers to change their shape will improve your vision. In the early development stages of LASIK, there were several complaints that came up after treatment. So for the past ten years, technicians have been creating new LASIK technologies that will improve the overall results and safety of LASIK eye surgery. 1. Wavefront Technology
Wavefront technology was developed in the early 21st century. Wavefront LASIK technology uses harmless rays of light that are sent into the eye and reflected off the retina. This allows the visual system to be measured with a 3-D map, giving precise specification for your eye. The recorded measurements of your visual system are then transferred to the actual laser to reshape the cornea during Wavefront LASIK surgery, providing the most accurate and precise results achieved by any laser vision correction system. 2. All-Laser LASIK
Also called IntraLasik and produced by the IntraLase Corporation, IntraLASIK provides remarkable accuracy, and may enable patients who have previously been dismissed as high risk to be re-evaluated for vision correction surgery. This level of precision reduces patient anxiety and significantly reduces or eliminates the possibility for complications that may occur with conventional LASIK . This level of safety is a first in vision correction technology. IntraLASIK can truly make vision correction surgery one of the most rewarding decision of your life. A choice to be made with confidence. IntraLASIK is considered by many to provide a safer approach to vision correction surgery. This is a result of the superior precision of a computer controlled laser as compared to that of a hand-held mechanical device. IntraLASIK reduces the risk of complications reported with conventional LASIK. Most patients agree that the added level of safety and assurance offered by IntraLASIK is well worth the additional cost when considering vision correction surgery. 3. Advanced Control Eyetracking (ACE) Technology
This was developed by Technolas Perfect Vision. The Eyetracker locks on to specific details in the iris. This information allows lasers to automatically adjust to eye movements during the surgery, to accurately reshape the cornea according to the surgical plan made before the operation. Based on a study of 2,000 LASIK San Francisco cases, the use of ACE increases the chance of curing astigmatism and reduces the chance of going back to the surgeon for another operation. 4. Bausch & Lomb's Orbscan® IIz
Bausch & Lomb's Orbscan® IIz is a fully integrated multidimensional diagnostic system that elevates diagnostics beyond mere topography. Unlike current topography systems which scan the surface of the eye at standard points, the Orbscan II acquires over 9000 data points in 1.5 seconds to meticulously map the entire corneal surface (11 mm), and analyze elevation and curvature measurements on both the anterior and posterior surfaces of the cornea. By providing more comprehensive pre-op diagnostics and planning, exclusionary criteria such as keratoconus, pre-keratoconus, and corneal thinning can be identified to optimize outcomes in both primary treatments and enhancements. The Orbscan II may help explain decreased visual acuity post-op, and is designed to allow the surgeon to more accurately prescribe retreatments, if necessary. The latest technology in eye surgery is the microwave systems being developed by Avedro, Inc. Instead of using needles or lasers, Avedro, Inc. is developing an eye correction system that involves microwaves. There is no tissue cutting involved with this new technology. However, it is important to note that this new technology is not meant to be permanent and is targeted only for patients with minimal nearsightedness. There are always new developments occurring in eyesight correction. Some will be more expensive than others. Regardless of price, it is important for you to do your own research and ask your surgeon which eye correction procedure will work best for you.
