Feinerman Vision Center is one of the leading eye care practices in the USA, because of our excellent customer service, years of experience and our top-notch facility. Feinerman Vision Center is home to one of Orange County’s best LASIK doctors, who only uses the best technology. The equipment and expertise we employ at Feinerman Vision Center allows for safe and effective procedures. This, combined with our world class customer service translates into a positive LASIK experience for our clients.
Dr. Feinerman has access to multiple laser technologies, which allows him to choose the best technology for each individual patient.
One of the lasers used during blade-free LASIK is a femtosecond laser. The femtosecond laser is used to create the corneal “flap”, which is temporarily lifted in the second step of the LASIK procedure to make the necessary adjustments to the corneal shape. At Feinerman Vision Center, we use the Ziemer femtosecond laser to create the corneal flap (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. He believes the advancement in femtosecond laser technology with the Ziemer laser 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.
The excimer laser is used to remove micron amounts of corneal tissue. This changes the corneal curvature during LASIK, which corrects refractive error. After the flap is created using the Ziemer femtosecond laser, Dr. Feinerman utilizes the excimer laser to reshape the cornea.
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.
Feinerman Vision Center is one of the first vision centers in the US to offer the new CATz (Customized Aspheric Treatment Zone) LASIK technology that takes Custom LASIK to a whole new level. This system is a unique combination of the fully-integrated Quest excimer laser, the OPD-Scan III, the OPD-Station software. This system is extremely technologically advanced, providing outstanding clinical performance and clinical outcomes.
CATz provides detailed topographic maps – one of the cornea prior to surgery, and another of the cornea as it should appear after correction with LASIK. These before and after images enable Dr. Feinerman to correct nearsightedness and astigmatism with unparalleled precision, as well as smooth out even minor irregularities.
LASIK Surgery is the process of correcting nearsightedness and astigmatism by changing the shape of the cornea. The laser fires a stream of up to 40 pulses of invisible ultraviolet light per second. Each pulse lasts only a few billionths of a second. Each pulse removes micron amounts of corneal tissue by evaporating it. To treat nearsightedness, the pulses are placed in a pattern that makes the cornea flatter. The laser produces very little heat and is controlled by the doctor during the operation.
Like regular LASIK, Topography-Assisted LASIK uses measurements of your nearsightedness and astigmatism to plan the treatment for your eye. In addition, it uses your eye’s unique corneal topography map to treat small irregularities that cannot be corrected by glasses.
