LASIK Technology

Understanding LASIK

LASIK, or "laser-assisted in situ keratomileusis," is a specialized procedure to correct common vision problems, including nearsightedness (myopia), farsightedness (hyperopia), astigmatism, and presbyopia. Like other types of refractive surgery, the LASIK procedure reshapes the cornea, allowing the light that enters the eye to be properly focused on the retina for clearer vision. Patients benefit from improved vision and reduced (or eliminated) dependence on prescription eyeglasses and/or contact lenses.

At Silk Vision, we employ the most advanced treatment and surgical technologies to deliver world-class LASIK right here in Northern Virginia. Explore the options available to you, so that you can better discuss them with Dr. Silk or the team at Silk Vision if you are interested in this elective vision correction surgery.

WaveLight® EX500 Excimer Laser

WaveLight® EX500 Excimer Laser

The WaveLight® Refractive Suite is the fastest refractive surgery platform available in the U.S. and the EX500 Excimer Laser is the only excimer laser to operate at 500 Hz. This allows Silk Vision to dramatically enhance the precision, reliability, and safety of the laser vision correction procedure.

Its innovative engineering and swivel bed is designed to optimize time between the flap creation and laser procedures, while reducing the potential for:

  • Stromal dehydration of the cornea
  • Flap shrinkage
  • Sensitivity to eye movements
  • Patient fixation fatigue

The cutting edge of laser technology, designed with precision and efficiency in mind.

The EX500 replaces its predecessor the EYE-Q laser, also manufactured by Alcon. It combines several innovations to enhance the success of treatment and visual results for patients. The LASIK procedure is bespoke to each eye, with customized pupil-center centration options among different lighting conditions.

With a powerful 1050 Hz-type multi-dimensional eye tracker, synchronized at 500 Hz, the WaveLight® EX500 Excimer Laser offers safety and exceptional precision, including movement tracking with just 2 milliseconds of latency and dynamic pupil tracking from 1.5 mm to 8.0 mm. Featuring enhanced beam path technologies, the WaveLight® EX500 Excimer Laser sets the standard for laser precision and durability.


Contoura Vision

Contoura Vision

Contoura Vision is used at Silk Vision & Surgical Center to provide patients in the greater Annandale area with the latest in topography-guided LASIK. The Contoura Vision system allows Dr. Silk to provide a fully personalized LASIK experience by providing measurements and data specific to the patient’s eyes, which are then used to skillfully map the LASIK procedure.

Contoura Vision is an exceptional option for patients with combined astigmatism and nearsightedness, thanks to its highly precise diagnosis of both corneal irregularities and refractive error.

Contoura Vision differs from standard Wavefront-guided LASIK because it measures far more points of curvature on the cornea. While Wavefront-guided LASIK measures approximately 200 points of curvature, the Contoura Vision system measures 22,000 points, which allows for a personalized treatment plan based on contours unique to each patient’s cornea. This ‘map’ is programmed into the laser used for LASIK, allowing Dr. Silk to smooth out any irregularities of the cornea for outstanding visual outcomes.

Visual outcomes are exceptional with Contoura Vision; many patients experience 20/20 vision or better when using this topography-guided LASIK technology. Contoura is also known to reduce negative visual outcomes sometimes associated with the LASIK procedure, such as glare and light sensitivity.
