LASIK NYC Technology – Diagnostic Tools

Print Friendly


Precise, in-depth screening

Dr. Ilan Cohen is considered one of the top cornea and refractive surgeons in the New York Tri-State area. Because patient safety and satisfaction are paramount to him, Dr. Cohen performs in-depth screening with advanced diagnostic tools as the first crucial step toward safe laser eye surgery.

Thanks to this industry-leading diagnostic technology, Dr. Cohen can quickly and accurately evaluate your eyes and determine your candidacy for LASIK, PRK, Visian ICL (implantable contact lenses), cataract surgery, and all other New York and New Jersey laser vision correction procedures.

The center of the cornea is the primary focus of laser eye surgery, and these tools give Dr. Cohen the ability to accurately measure its shape, contour, thickness and irregularities before and after surgery. Corneal topography, for example, creates a map of the elevations and depressions on the surface of your cornea. Think of it like a topographical map of the earth’s terrain which provides a 3-D illustration of mountains and valleys.

To ensure that the surgical recommendations he makes will always be as safe and precise as possible, Dr. Cohen insists on using the finest diagnostic tools manufactured by the leaders in optical lenses, such as Oculus, Zeiss, Alcon, Bausch and Lomb, WaveTec, Abbott Medical Optics Inc. (AMO), and so on. Here are a few of the state-of-the-art tools we use at 5th Avenue Eye Center:

Oculus Pentacam®

lasik nyc-Oculus-Pentacam-advanced-diagnostic-toolsDr. Cohen considers the Pentacam® (Oculus GmbH, Wetzlar, Germany) to be the ultimate diagnostic tool for corneal topography when planning cataract, lens implant and laser vision correction surgery. In less than 2 seconds per eye, the Pentacam’s high resolution rotating Scheimpflug camera scans the anterior eye (cornea, anterior chamber, iris, and lens) and measures up to 25,000 data points on the front and back surfaces of the cornea which are then stitched together into a 3-D model.

Bausch & Lomb Orbscan® II

Orbscan IIThe Orbscan® II (Bausch & Lomb, Rochester, NY) is another tool used to analyze the contours of your cornea and determine if it has a suitable shape, and is healthy and thick enough for LASIK or cataract surgery. To have successful LASIK surgery, for instance, your cornea must have enough tissue for both the corneal flap and to correct your refractive error. If the 3-D Orbscan® topographical map measures corneal thinning or keratoconus, you may be a better candidate for another laser eye surgery, such as LASEK or PRK. Orbscan® measures up to 9,000 different points on the cornea in less than 2 seconds.

Alcon Allegretto WaveLight® Analyzer

WaveLight AnalyzerThe newest generation of laser vision technology incorporates the individual wavefront measurements of your eye into the formula so that your treatment can be customized to suit the unique curvature of your cornea. The Allegretto WaveLight® Analyzer scans your cornea, measures the complete optics of the eye, and collects wavefront aberration data. The results may broaden your possible treatment options from the wavefront-optimized LASIK procedure to the highly sophisticated wavefront-guided treatment. If you are a qualified candidate, your surgeon will use this data to customize your LASIK procedure. The precise measurements are delivered directly to the Allegretto Wave® Eye-Q excimer laser to carry out your treatment.

AMO WaveScan WaveFront™ System

AMO WaveScan WaveFrontOne way to measure the focusing errors of your individual eye prior to laser vision correction is to measure its wavefront with specialized cameras. This can be accomplished with an advanced diagnostic tool like the WaveScan WaveFront™ System (AMO Manufacturing USA, LLC, Milpitas, CA). The WavePrint™ Map produces a measurement of how light rays travel through your eye compared to the way light travels through an eye that is optically perfect. Basically, it gives your surgeon a “fingerprint” of your unique vision, and, along with other measurements, becomes your surgeon’s blueprint for customizing your vision correction. This wavefront analysis is transferred to the excimer laser for your Custom LASIK procedure.

Zeiss IOLMaster®

Zeiss IOLMasterIn cataract surgery and other lens replacement procedures, the natural crystalline lens of your eye is replaced by a new, clear intraocular lens (IOL). These IOLs come in different sizes and powers, so it’s very important that measurements of your eyes prior to surgery are as precise as possible. The high-precision Zeiss IOLMaster® uses short light waves to measure your eyes and is three times more accurate than the standard ultrasound (long sound waves) method. The IOLMaster® delivers fast and accurate measurements of the eye length and surface curvature, and the device never touches the cornea so there is no discomfort. This is another advanced diagnostic tool that allows us to provide you with the best visual outcomes.

The difference between good and great vision after laser vision correction surgery can be attributed to the technological breakthroughs that allow highly skilled surgeons like Dr. Cohen to accurately and precisely measure more elements of your eye than were ever imaginable. If you have any questions at all or simply want to know more about LASIK NYC, PRK, Visian ICL, cataract surgery, and other laser vision correction options at locations in Manhattan, Glendale NY, the greater NYC area, or Old Bridge, New Jersey and surrounding cities, we welcome you to call us at (212) 764-2020 or (866) 731-3937, or click below to schedule a consultation with Dr. Cohen.
