Conventional LASIK vs. Custom LASIK
If you’re tired of being dependent on glasses and contact lenses, LASIK surgery may be a great option. The LASIK procedure is generally quick, convenient, virtually pain-free, and many patients are able to stop using glasses or contacts completely after they’ve recovered from surgery.
Thanks to continual advances in technology, custom LASIK has emerged. While conventional and custom LASIK are both safe and effective solutions to nearsightedness, farsightedness and astigmatism, there are a few key differences between the two procedures.
The primary difference between the two is that custom LASIK incorporates wavefront technology to diagnose and treat the specific imperfections of your eye. The procedure is tailored specifically to your vision correction needs. Before custom LASIK surgery, three-dimensional measurements of the eye’s corneal surface and its visual abnormalities are obtained via wavefront technology. These measurements are then entered into a computer program, which calibrates and guides the laser during surgery.
Both traditional and custom LASIK procedures are fairly quick, with recovery procedures and timelines being somewhat similar.
Custom LASIK Options
ALLEGRETTO WAVE® Eye-Q
Custom LASIK (wavefront technology) has been a major breakthrough for the field of vision correction. LASIK patients can now benefit from customized LASIK treatments with the new Optimized LASIK system of the ALLEGRETTO WAVE®. The ALLEGRETTO WAVE® Eye-Q customizes every treatment based on the patient’s individual prescription and the shape of their cornea, aiming to reduce glare and halos and improve night vision.
One of the most innovative features of the ALLEGRETTO WAVE is the way it uses wavefront-optimized technology to automatically compensate for the curvature of the cornea. In earlier laser correction systems, the “optical zone,” or area of correction, was centered on the front of the cornea; the result was a flattened circular area that ended with an abrupt edge, causing unwanted side effects like poor night vision, glare, and halos.
Wavefront Optimized® LASIK was developed to consider the unique curvature of the eye, preserving the natural, aspheric shape of the cornea, for less induced spherical aberration. This provides improved quality of vision and eliminates or reduces the spherical distortions that can cause glare and may affect night vision.
Ziemer Custom LASIK (Z-LASIK)
The Ziemer femtosecond laser is completely controlled and guided by our board certified ophthalmologist, Dr. Feinerman. It is completely bladeless. Z-LASIK is unique because it uses extremely small and rapid laser pulses to create the corneal flap (essential to the LASIK procedure). The lower energy released with each pulse using Ziemer technology is the main factor in improved overall safety. This gives our patients faster healing time and faster visual recovery than any other technology in the world.
Orange County-based LASIK expert Dr. Gregg Feinerman has performed thousands of LASIK procedures since 1998. He believes this advancement in femtosecond laser technology has significant advantages over the older Intralase technology. Dr. Feinerman wants to provide the best patient care and highest level of safety for his Orange County area LASIK patients. Furthermore, he believes the more accurate Ziemer femtosecond laser will enable more people to safely undergo LASIK eye surgery.
Is Z-LASIK Safer Than Intralase?
Z-LASIK actually allows a more precise creation of the LASIK flap and a more evenly shaped corneal flap. This more evenly shaped corneal flap actually enables a more uniform surface for the excimer laser treatment that follows the flap creation. The pulse energies are much lower (nanojoules) than that of Intralase (milijoules), which provides safer delivery of the energy. Additionally, the Ziemer’s delivery optics are very tightly focused for more precision. Therefore, some experts like Dr. Feinerman believe that Z-LASIK is safer and better than Intralase.
Dr. Feinerman was the first surgeon in California to acquire the Ziemer laser. He made the decision to invest in the new technology due to these safety factors. Feinerman Vision Center offers what we believe is the safest LASIK experience with exceptional results. Not only is this laser technically better than Intralase; but it also allows a thinner more precise LASIK Flap than what can be achieved with a mechanical blade-driven microkeratome.
