If you suffer from nearsightedness, farsightedness, or astigmatism, and you feel that glasses or contact lenses limit your activities, LASIK may be right for you. Look beyond a lifetime of glasses and contact lenses…and enjoy a better way to see. When you’re deciding to have surgery on your eyes, you want to know what you can expect. Many surgeons tell you general LASIK results, but most don’t offer specific information about their results with people just like you … and most won’t put it in writing. But we will. No matter what your current situation is, we’ll provide you with specific information about your likelihood of achieving 20/20 vision. There’s no guessing and no generalities. Just the actual data to help you make an informed decision.
With recent advances, more and more people are becoming prime candidates for laser vision correction, even when they’ve been told in the past they were not.

Our Lasik Technology

WaveLight® EX500 Excimer Laser System
We perform all of our treatments on the WaveLight® EX500 Laser, the fastest refractive surgery platform available in the U.S.. The only excimer laser to operate at 500Hz, with an average treatment time of 1.4 seconds per diopter*. Built on trusted WaveLight excimer technology, the WaveLight® EX500 Excimer Laser is the next leap forward in fast, accurate refractive laser treatments.

Wavefront Optimization
The WaveLight® EX500 Excimer Laser utilizes wavefront optimized technology to capture and automatically compensate for the unique curvature of your eyes, allowing your doctor to customize your laser vision correction treatment and preserve the highest quality of vision.
With earlier laser systems, the “optical zone”, or area of correction, was centered on the front of the cornea; the result was a flattened circular area that ended with an abrupt edge, causing unwanted side effects like poor night vision, glare, and halos.
The illustration below demonstrates the use of additional pulses to the cornea periphery which preserves the aspherical shape of the cornea. This compensation, combined with the incredible small 1mm size of the laser beam, produces a smooth, effective optical zone that results in higher quality vision.
PerfectPulse™ Technology and Smart Energy Control
The Allegretto laser is the fastest and most precise laser system with the ability to treat the widest range of nearsightedness, farsightedness, and astigmatism. The PerfectPulse Technology™ safely and accurately controls every single laser pulse from start to finish. It is applied to help ensure safe and precise work at high speed.
Smart Energy Control automatically measures and balances the energy level to ensure that each laser pulse delivers the same accurate result. After the beam has been created, it passes through three check points, where the energy level is checked and adjusted if necessary, ensuring that the beam is perfectly attuned to its destination.
Eye Tracking Technology
High-speed eye tracking is used to follow the eye’s fastest movements. Every 4-6 milliseconds, the eye’s location is measured and the internal mirrors of the WaveLight are automatically aligned. Just before each pulse is released, a final check is made to confirm the position of the eye. This happens 200 times every second, once for every laser pulse.
As a result of these unique technologies, the WaveLight® EX500 Excimer Laser is completely controlled, achieving the most accurate level of correction possible.

Oculus Pentacam
The Oculus Pentacam is an essential tool for diagnosis and management of corneal, cataract, and refractive surgery.
The innovative technology of the Pentacam has enabled physicians to analyze the front surfaces of the eye with an accuracy that was previously not available, thus permitting them to diagnose eye conditions and diseases with greater confidence.
The pentacam captures a high resolution image of the anterior eye segment and provides information from the anterior corneal surface to the posterior crystalline capsule. The images generated are three-dimensional rotating models used for corneal topographic and chamber analysis. They are movable presentations that are highly reliable and precise.
Key advantages of the rotating image process are:
- Precise measurements of the central cornea
- The correction of the eye’s movement
- The easy fixation for the patient
- Extremely short examination time
Best Diagnostic Technology for LASIK Treatment
We use only the most advanced diagnostic equipment to determine your candidacy with the utmost confidence. During your free 60-minute consultation, we’ll perform a thorough examination including:
- auto-refraction
- pupillometry
- corneal topography
- pachymetry
These tell us about, not only your prescription but the size of your pupils, the shape, health and thickness of your cornea, and the level of aberrations present in your visual system. All are critical in determining if LASIK is right for you.

From the consultation room to the laser suite, you’ll notice the difference! Our goal has always been to provide the best technology, superior surgical results, and a laser vision correction experience so outstanding you’ll want to tell all your friends.
What is 20/20 Vision?
Generally speaking, if your visual acuity is determined to be 20/20, you see at 20 feet what a person with normal vision sees at 20 feet. Comparatively, if you have 20/40 vision, you see at 20 feet what a person with normal vision could see from 40 feet. And, if you’re one of the lucky ones who has 20/15 vision, you can see at 20 feet what others would have to move up to 15 feet to see.
Will I See 20/20 After LASIK?
After LASIK, most patients see as well, if not better, than they did with their glasses or contacts. As a matter of fact, one thing that makes our office special, is that we’ll provide you with our actual results with other patients as your same prescription – in writing. Whatever your prescription, we’ll provide you with specific information about your likelihood of achieving 20/20 vision. No guessing. No generalities. Just the actual data to help you make an informed decision.

LASIK Eye Surgery Results
Results matter most. So be sure to research what other patients are saying about their own experience with your surgeon. Specifically, look for reviews about how they were treated, before, during and after their LASIK procedure.
Also, pay attention to their reviews about their vision after LASIK. How well do they see? Are they happy with their vision? Your LASIK experience should be both enjoyable and effective. Taking time to identify top surgeons with outstanding patient care will help you achieve both.

I highly recommend Dr Warren and this practice for EYE procedures. I had a PRK procedure done (didn’t qualify for LASIK based on my eyes). The procedure was about 5 minutes and Dr Warren walked me through every step as he was preforming it. This eased my nerves and made the entire process easy. Great and clean facility. Great techs, optometrists, and ophthalmologists!July 28, 2025
