Refractive Surgery Technology: Innovative Approaches to Enhanced Vision

Dr. Andrew E. Holzman incorporates several state-of-the-art technologies in order to provide patients with individualized care. Our technological devices allow us to obtain detailed information about your eyes and your vision, so that we can create a treatment plan unique to you. During your consultation with Dr. Holzman, you will learn more about which of our technologies will be used to improve your vision safely and precisely. Contact us today to learn more about the refractive surgery technology we use at our Washington, DC-area practice.

Wavelight® FS200

The WaveLight® FS200 Femtosecond Laser provides precise and efficient treatments resulting in reliable patient outcomes.  For highly advanced LASIK treatments, the WaveLight® FS200 Femtosecond Laser offers customized flap creation options relative to individual adjustment of flap size and shape, adjustable hinge position and hinge size, and variable angles for the side cut incision.


The IntraLase® FS Laser allows Dr. Holzman to create a micro-thin corneal flap in a shorter, more precise procedure. While traditional LASIK surgery involves using a microkeratome blade to create the corneal flap, IntraLase® allows your doctor to use laser technology to create a customized corneal flap without the use of a blade. This laser technology shortens surgery time, and allows for a faster recovery.

Wavelight® EX500 Excimer Laser

The WaveLight EX500 Excimer Laser system combines a number of innovations in refractive technology to produce fast, effective and reliable procedures.1–4 Its proven, state-of-the-art technology results in excellent Wavefront Optimized® and Wavefront-Guided laser vision correction.

Allegretto Wave™

The Allegretto Wave™ laser system provides individualized vision enhancement. The system uses advanced eye-tracking technology to provide precise correction. This system can treat a wide variety of refractive errors, making it a viable option for many patients. The Allegretto Wave™ provides patients with enhanced daytime and nighttime vision. 


Wavefront technology offers precise diagnostic measurements of the eye. It detects visual imperfections called aberrations, which include lower-order aberrations and higher-order aberrations. Refractive errors such as nearsightedness, farsightedness, and astigmatism are lower-order aberrations. Higher-order aberrations are more complex visual errors that can result in glare, halos, starbursts, blurred vision, or double vision. With the advent of Wavefront technology, we can correct both lower- and higher-order aberrations to provide extremely clear and precise vision.

VISX CustomVue™

The STAR S4 IR® laser system provides CustomVue® laser vision correction. Eye-tracking technology allows the laser to adjust according to any eye movement that may occur when the patient is lying down. CustomVue® reduces thermal effects on the cornea, making vision correction more precise, more efficient, and safer than ever before.

Other Technologies

We use several other technologies to provide patients with high-quality care and enhanced vision. Advanced diagnostic systems help us determine if you are a candidate for LASIK surgery. The Humphrey® ATLAS™ Eclipse Corneal Topography System creates a 3-D map of your cornea, providing necessary information to determine the amount of corneal tissue that will be removed during surgery. The Orbscan™ II by Bausch & Lomb measures the front surface of your eye, helping to determine your candidacy for LASIK. We use the Colvard Pupillometer to measure the dilation of your eyes, and the OCULUS Pentacam® to obtain information about the elevation of your cornea. By obtaining extremely precise measurements of your eyes prior to surgery, we can reduce the chance of complications and make the best surgical recommendations for you.
