LASIK Technology

At Diagnostic Eye Center in Houston, we take pride in providing our patients throughout the Houston area with the latest technology in laser vision correction. Our modern LASIK center is equipped with the Alcon WaveLight® Refractive Workstation.

The Wavelight® FS200 Femtosecond Laser

The WaveLight’s revolutionary approach to laser eye surgery technology minimizes problems associated with older generation lasers, such as night vision reduction, glare, and halos.


Faster Flap Creation: Featuring the nation’s fastest flap creation times, the 200 kHz WaveLight® FS200 Femtosecond Laser delivers precise, predictable outcomes:

  • Standard flap creation in approximately 6.0 seconds
  • Automated vacuum control of the patient interface for consistent suction
  • Minimized IOP and ocular distortion during suction
  • Fast visual regeneration


Built for Speed and Superb Outcomes: Featuring a 400 Hz repetition rate, the WaveLight® Allegretto Wave® Eye-Q Excimer Laser delivers one of the world’s fastest ablation times at only 1.4 seconds per diopter, resulting in consistent outcomes.

  • High speed 400 Hz eye tracker actively tracks the fastest eye movement and verifies location before releasing
  • pulses
  • Thermal optimized shot distribution helps minimize the potential for thermal buildup
  • Crossline projector provides precise centration

What are my options if I wear bifocals?

If you’re over the age of 45, you may wear bifocal glasses or contacts.  This is because of a condition called presbyopia.  Presbyopia occurs when the lens inside the eye naturally loses its ability to focus on objects up close.  LASIK can only correct distance vision or near vision, but not both at the same time. For patients under the age of 40-45, this is not an issue, as the focusing mechanism in their eyes still allows them to see near.

For patients who wear bifocals or reading glasses now, there are three options for vision correction surgery.

Distance Only: One option is to correct only the distance vision and then wear drugstore readers as needed for close vision.  For patients that want the best possible vision at distance, such as those that drive for a living or those with very active lifestyles, this may be the preferred option.  With the option of new Vuity eye drops for near vision, patients can even be less dependent on reading glasses than before.

Monovision: Another option is called monovision, in which one eye is corrected for distance and the other is corrected for near.  The brain learns which eye to use, depending on whether you are focusing on a distant or near object.

Oftentimes, monovision is implemented with contact lenses, but it can also be done with refractive surgery, such as LASIK, or with cataract surgery. It is important to understand that monovision may not be the best option for everyone.

You should discuss this option thoroughly with one of our doctors to determine if you would benefit from monovision correction. We generally recommend a brief trial period with contact lenses to ensure you are comfortable with monovision correction before proceeding with LASIK.

Refractive Lens Exchange: Premium intraocular lenses now provide another alternative through a procedure called Refractive Lens Exchange.  These lenses are implanted in the eye and can correct distance and near vision simultaneously. Your doctor will discuss your options with you at your consultation.
