Custom LASIK

Custom LASIK has taken LASIK to a whole new level.

Allegretto Custom LASIK at Feinerman Vision Center Newport BeachThat’s because custom LASIK doesn’t just attempt to fix your eyeglass prescription. It does that, but also addresses other causes of night vision problems called “higher order aberrations”. By removing higher order aberrations (ie. spherical aberration and coma), night vision usually improves after custom LASIK.

“In fact, recent studies with wavefront driven or wavefront optimized treatments, including the USA FDA sponsored PROWL1 and PROWL2, night vision symptoms were less after surgery than they were before surgery” — Gregg Feinerman, MD, FACS

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 that cause difficulty with night vision. The procedure is customized to your eye, which improves the quality of your vision compared to conventional LASIK. Before your 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. Custom LASIK procedures are fairly quick, with recovery occurring at a rapid rate. Dr. Feinerman performs custom LASIK on all of his surgeries, providing they are good candidates.

Custom LASIK (wavefront technology) has been a major breakthrough for the field of vision correction. LASIK patients can now benefit from CONTOURA customized LASIK treatments with the new ALLEGRETTO laser.  It 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 is the way it uses wavefront 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 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.Picture of Alcon's Wavefront Topographer

CONTOURA is Topography guided LASIK.  That means it links your eye scans (topography) to the laser treatment, correcting the irregularities found on your specific eye.  Customer satisfaction has been very positive, with more than 98% of patients reporting they would choose it again.  CONTOURA even outperforms glasses and contacts (baseline best corrected visual acuity) in over 30% of eyes.  When compared to baseline, it actually improves many common symptoms associated with LASIK.  Thus, CONTOURA redefines visual acuity outcomes and delivers a high level of personalization.

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 images 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.

Like regular LASIK, Topography guided 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.
