Custom LASIK Treatment Exclusive

Allegretto Wavelight Laser

Allegretto Wavelight Laser - LASIK Technology Denver Colorado

The Allegretto WaveLight utilizes PerfectPulse Technology™, which is responsible for the speed, precision, and safety of the laser. This control can track the eye’s movement 200 times per second. Every few milliseconds, the eye is measured and the Allegretto WaveLight automatically aligns itself, immediately before the laser pulse is delivered. If the eye moves, the laser pulse moves, if the eye moves too much, the laser can pause. LASIK was highly successful even before the advent of eyetracking which has made it that much safer.

The State-of-the-art Allegretto Wavelight Laser takes an innovative approach to laser vision correction. This technology can reduce or eliminate glare and halos at night. It is also fitted with a tracking system to make sure each pulse of laser energy is precisely delivered. Unlike other lasers, the Allegretto WaveLight adjusts to the patient’s corneal eye curvature. This allows for corneal reshaping in the patter of a smooth spherical curve, an improvement over most if not all other excimer laser systems.

This technology also has the largest corneal correction zone in excimer laser vision correction. The Wavelight Allegretto with its wavefront optimized pattern, reduces or eliminates glare and haloes in patients with large pupils. No other laser can match this feature or achieve this result.

VISX Star S4

VISX Star S4 LASIK TechnologyThe VISX Star S4™ is an excimer laser manufactured by Johnson & Johnson. The Star S4™ laser is FDA approved to treat nearsightedness, farsightedness, and astigmatism. This amazing piece of technology contains the 3D ActiveTrak™ eye tracker, which tracks horizontal, vertical and up and down motion of the eye in real time, which allows every laser pulse to be more precise, even with eye movement.

The VISX Star S4™ includes Iris Registration technology. This allows for increased precision, especially for patients who have astigmatism. With Iris Registration, each and every laser pulse is targeted and delivered with unsurpassed precision.


Clinical Studies

The results of the FDA’s clinical study on visual acuity show that 6 months after the VISX CustomVue™ procedure:

  • 100% of patients could see 20/40 or better
  • 98% achieved 20/20 or better
  • 70% were 20/16 or better


Overall, many patients were pleased with their quality of vision, with four times as many patients satisfied with their night vision when compared to wearing their glasses or contacts.

The WaveLight® EX500 Excimer Laser

This innovative FDA approved laser offers amazing 500Hz speed, PerfectPulse Technology®, which helps reduce procedure times and can improve outcomes and increase patient comfort. Patient recovery times are also minimalizing by reducing inflammation, swelling and dryness.

In the past, patient eye movement was sometimes a difficult issue to overcome. However, the WaveLight® EX500 excimer laser has the fastest multidimensional eye tracker which is more than twice as fast as previous models, moving from 400 times per second to an incredible 1050 times per second. That’s 10 times fastest than the human eye can move!

The WaveLight® EX500 excimer laser’s perfect pulse technology ensures safety and precision for our LASIK and PRK patients. It delivers an accurate pattern of pulses to the peripheral edge of the cornea (the portion of the eye being treated during laser vision correction), which can reduce the risk of nighttime glare and halos. The laser can also monitor corneal thickness before, during and after the treatment, which helps Dr. Cutarelli maintain constant awareness of his patients’ corneal thickness during the LASIK procedure.

This major advancement in refractive surgery increases speed, accuracy and safety and allows Dr. Cutarelli to treat a wider range of patients, such as those with high amounts of nearsightedness, farsightedness and even astigmatism. Cutarelli Vision is proud to be the first in the Denver area to offer this amazing technology to Colorado.

WaveLight® FS200 Femtosecond Laser

WaveLight® FS200 Femtosecond Laser

At Cutarelli Vision, we take pride in offering our patients innovative laser vision correction technologies. That’s why we’re proud to be the first in Colorado to offer the WaveLight® FS200 Femtosecond Laser by Alcon.

LASIK is a two-step procedure; the first step involves creating a protective flap (femtosecond laser) before reshaping the cornea to the desired shape (excimer laser). The WaveLight® FS200 Femtosecond Laser offers one of the fastest flap creative times, approximately 6 seconds, which can help improve precision and visual outcomes. This tremendous 200Hz speed also reduces patient discomfort and allows for a faster recovery time.

Dr. Cutarelli who has performed over 70,000 vision correction procedures believes the WaveLight® FS200 is one of the finest femtosecond lasers ever developed. It combines an extremely low energy pulse and uses unique patterns for creating personalized corneal flaps. Dr. Cutarelli can use the WaveLight® FS200 to create an individialized protective flap to any size, shape, location and depth, allowing for a wider range of surgical options.

CustomVue® Wavefront-guided LASIK

CustomVue LASIK uses WaveScan® digital technology to improve the visual outcomes of LASIK. Originally developed for the Hubble Space Telescope to reduce distortions when viewing distant objects in space, WaveScan technology can identify, measure and correct imperfections in your eyes 25 times more precisely than with standard methods used for glasses and contact lenses. First, a patient will have a Wavescan measurement to get measure any amounts of nearsightedness, farsightedness or astigmatism. Then, the laser captures the “unique” imperfections in the eye that cause glare, halo or other abnormalities. This detailed information is transferred to the laser, allowing Dr. Cutarelli to map and correct your eye’s optical imperfections with precision.

Wavefront LASIK

Wavefront-guided LASIK Denver

Wavefront-guided LASIK is personalized for you, resulting in sharper, clearer vision and reduced risk of side effects such as glare, night vision difficulties, and halos which can sometimes occur following standard LASIK procedures.

An FDA clinical study showed the following results from patients 12 months after undergoing Custom LASIK:

  • 100% could pass a driving test without glasses or contact lenses
  • 98% could see 20/20 or better without glasses or contact lenses
  • 70% could see better than 20/20 without glasses or contact lenses

Intralase Femtosecond Laser

Intralase All-laser LASIK

LASIK flap creation systems are not created equal! LASIK is a two-step process. The first step involves creating a protective corneal flap and the second step involves using an excimer laser to reshape the cornea to the desired shape to give you good uncorrected vision. At Cutarelli Vision, we perform LASIK surgery with a microkeratome. We feel that Intralase is the safest and most precise form of vision correction. Although a blade or “microkeratome” is very safe, the Intralase can be safer. Because Intralase can make extremely precise, thin protective flaps, LASIK also allows Dr. Cutarelli to perform LASIK on patients who would not have been a candidate due to thin corneas.

The Intralase Femtosecond (FS) LASER is used to create the corneal flap. We are pleased with the amazing precision offered by the Intralase machine, and hope we can pass along this great precision in the vision of our patients.

Eyes treated with the IntraLase have fewer visual errors (haze, glare, sensitivity), less discomfort, and less dryness than a microkeratome. The Intralase offers flaps of precise thickness, and greater control of the flap design, which reduces risks, while producing superior visual outcomes.

Moria M2 Microkeratome

LASIK Microkeratomes

Microkeratomes have the longest track record for the creation of the LASIK flap. The Moria M2 microkeratome has been exquisitely designed by an ophthalmic device company in France with over 150 years of history. The Moria M2 creates the thin protective flap in the cornea during the initial step of a LASIK procedure. The Moria M2 has perhaps the best predictabilty for flap quality, precision, and accuracy.

A 2003 study by Jaime Javaloy, MD, PhD, Maria T. Vidal, MD, Antonio Quinto, OA, Victoria de Rojas, MD, PhD, and Jorge L. Alió, MD, PhD showed that the Moria M2 microkeratome had overall better predictability in flap thickness and the apparent quality over the Hansatome or the ACS. Most microkeratome study data and anecdotal opinion is based on the inferior performance of the Hansatome microkeratome and should not be extrapolated to the Moria M2 microkeratome, which has superior performance over other microkeratomes particularly for eyes with previous radial keratotomy (RK). Moria M2 in highly experienced hands will perform as well as femtosecond flap creation devices. Dr. Cutarelli has perhaps the most experience in Colorado with Moria microkeratomes.
