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.

Wavelight Allegretto Laser


There are two types of custom LASIK: wavefront optimized and topography guided.  Dr Feinerman chooses the best type for each individual depending on the results of the eye scans and clinical exam. LASIK patients can now benefit from both types of Custom LASIK with the 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.

For wavefront optimized LASIK, the Allegretto laser uses wavefront guided technology to automatically compensate for the curvature of the cornea.  This reduces 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.Picture of Alcon's Wavefront Topographer

Topography guided LASIK is the highest level of Custom LASIK.  The Allegretto laser’s version of topography guided LASIK is called Contoura. That means it links the scans of your eye (wavefront topography) to the laser treatment, specifically correcting the irregularities found on your eye. Contoura LASIK treats higher order aberrations on your cornea, which is more than just treating your eyeglass prescription. 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.

Nidek Quest Laser

Nidek Quest Laser

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 an even higher 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 wavefront 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 treating higher order aberrations (smoothing out even minor irregularities).

The Nidek Quest laser also performs both types of custom LASIK (wavefront optimized and topography guided).  As discussed above, 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.
