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.

Topography Guided Custom Ablation Treatments

The Contoura™ Vision is an advanced technology that performs Topography-guided custom ablation treatments (T-CAT) for patients who are nearsighted. This breakthrough technology allows ophthalmologists to treat a wider range of patients. By creating large optical zones, which allow doctors to fully replicate the cornea in a way that was not possible before, and ultimately provide them with better outcomes. It is designed to treat primary myopic vision, with or without astigmatism. The treatment is safe, effective, and can help you achieve enhanced visual acuity.   

KAMRA™ Inlay

The KAMRA™ inlay is a special lens made of a biocompatible material called polyvinylidene fluoride. It is thinner than a contact lens, with a smaller diameter (3.8mm). A small opening of about 1.6mm in the center of the lens acts like the aperture of a camera. It only allows focused light to reach the retina, increasing depth of focus. This small device is placed within the corneal tissue to improve close focus with a small aperture while leaving your distance vision unaffected. The KAMRA™ inlay offers many benefits, including improving close focus by as much as three lines on an eye chart.

Wavelight® FS200

Dr. Holzman's officeThe 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.

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.

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.
