Stahl vision laser eye center in Dayton Ohio

CustomVision™ Wavefront LASIK & PRK

At a Glance: If you have been waiting to have LASIK because you wanted the latest and best technology, the best prices, and the best results, well then your wait is over. Advances in measurement technology, using topography based measurements and wavefront analysis now allow us to correct the fine aberrations unique to each persons eyes to improve the image quality, contrast, and definition of the vision people experience with LASIK plus PRK. A Wavefront Map is like taking a fingerprint of the total optics of the eye, from the cornea to the retina, and is an infinitely more precise way of measuring the optics of your eye. A topography measurement measures the fine imperfections in the cornea, where most of the irregularities occur. Recently approved topography based LASIK (Topo-LASIK or Contoura LASIK) is the first FDA approved advancement in LASIK in over a decade! Topo-Lasik has the highest satisfaction rate of any LASIK procedure. And Topo-LASIK had the highest percentage of patients seeing 20/20 and better than 20/20. But our exclusive CustomVision technology doesn’t stop there. Dr. Stahl’s trademarked CustomVision technology uses exclusive nomograms to take our vision results far beyond the results found in FDA trials, and those found at other centers. Customized treatments go by several names including Topo-LASIK, Contoura LASIK, CustomCornea, Custom LASIK, Wavefront Guided LASIK, Wavefront Optimized LASIK, and Dr. Stahl’s own trademarked CustomVision™. CustomVision™ is a refinement of LASIK using advanced nomograms and wavefront imaging technology combined with topography measurements to achieve high contrast vision. We perform CustomVision™ using the Wavelight Allegretto Wave® Eye-Q Excimer Laser— the fastest and most advanced laser platform available providing exceptional levels of safety and effectiveness.

Wavefront technology has been used in astronomy and imaging technology to improve imaging, contrast, and definition for decades. Its use in laser eye surgery started in the late 1990’s when it was recognized that correcting more than just nearsightedness, farsightedness, and astigmatism could improve how well someone can see after
their LASIK surgery, especially in low light conditions.

High Contrast Vision Beyond 20/20 is a Reality for Many

Glossary: A Wavefront Map is a more precise measurement of your eye’s vision system. Wavefront Guided LASIK is used in Custom LASIK treatments like CustomVision™ is a refinement of Custom LASIK by Stahl Vision to achieve High Contrast Vision.

High Contrast Vision is similar to the high definition vision that you might have experienced while watching your high definition television (HDTV)-only it’s YOUR eyes providing the vision quality and not your TV! At Stahl Vision we strive to produce this level of vision correction quality for our patients through using the advanced technology of Wavefront Mapping and Wavefront Guided LASIK.

About High Contrast Vision and Optical Aberrations
Many patients do not realize that their eyes are an imperfect optical system. As light rays from distant objects pass through the individual optical components of the eye, they are subject to being distorted by the imperfections found in the Cornea and the Crystalline Lens. These distortions that are created are referred to as “aberrations.” Some aberrations can create common refractive errors, such as nearsightedness or myopia, farsightedness or hyperopia and astigmatism-these are called “Low Order Aberrations”. Low Order Aberrations such as these that cause common blurring of vision can be corrected with eyeglasses or contact lenses or by conventional Laser Vision Correction using LASIK or PRK. However, even with the best glasses and contacts may people still complain about their night vision and don’t like to drive at night.

One of the reasons for poor night vision is because of the tiny imperfections, or aberrations, in their vision, which exist in addition to being simply nearsighted or farsighted. These additional tiny aberrations include, spherical aberration, coma, trefoil, and quadrifoil-and are collectively known as “High Order Aberrations”. These aberrations, which cannot be corrected with glasses or contacts, can cause disturbing problems like halos and glare with your night vision. High Order Aberrations can actually give rise to visual symptoms that we can understand and perhaps have experienced, such as:

Starbursts – Patterns of Small Lights Around Light Sources
Haloes – Circles of Light Around Light Sources
Ghosting – A Faint Duplicate of Each Object Similar to Double Vision
Glare – Intensification of Light Sources

High Order Aberrations often involve night vision and the reduced clarity caused by imperfect vision in low light. They can be inborn or caused by trauma or disease or by Cataracts or Dry Eye Syndrome. They have also sometimes been side effects of traditional LASIK surgery.

These High Order Aberrations are entirely unique to a particular patient-much like a fingerprint. For these patients, to achieve the best vision correction results, the use of a Custom Wavefront Guided Laser Eye Surgery such as CustomVision™ to create a completely customized reshaping of the surface of the Cornea may be the best treatment option and can actually deliver High Contrast Vision Beyond 20/20!

Thanks to CustomVision™ LASIK and Stahl Vision, we are able to diagnose and correct these aberrations resulting in better clarity and improving night vision. Many patients are telling us they have never seen this well before.

Using this advanced technology, years of experience, and tracking the results of thousands of patients to fine tune results for each person based on their unique eyes. Dr. Stahl is achieving the best results they have ever measured: 99.3% of patients are 20/20 or better, and 81% are better than 20/20!

*For many patients, this is better than they have ever seen with glasses or contacts.
*Wavefront patients measured bilaterally.

Wavelight Allegretto Wave® Eye-Q Laser

Our commitment to the quality, safety and precision of the surgical results we achieve for patients is illustrated by the incorporation of the Wavelight Allegretto Wave® Eye-Q Excimer Laser System. Stahl Vision provides our patients Laser Eye Surgery using with the Wavelight Allegretto Wave® Eye-Q Excimer Laser System for the correction of nearsightedness, farsightedness and astigmatism including CustomVision™.

The Wavelight Allegretto Wave® Eye-Q Excimer Laser System ensures safe and precise laser energy delivery at high speed for vision correction procedures such as Custom LASIK and PRK. Using the Allegretto Wave® Eye-Q. Drs. Stahl & Knowles are able to apply tiny laser pulses to the Cornea to sculpt its surface with the utmost accuracy. The high-speed eye-tracker follows the eye’s fastest movements, checking the eye’s positions 4000 times per second while ensuring an accurate placement of each laser pulse on the Cornea. This makes the Allegretto Wave® Eye-Q the safest, most effective eye surgery laser currently available today.

Smart Energy Control
You can have peace of mind that the amount of energy in the laser has been calibrated to exactly the right level. After the beam has been created, it passes through three checkpoints on its way to your eye. At each of these points, the energy level is checked and adjusted if necessary, ensuring that the beam is perfectly attuned at its destination.

Eye Tracking Technology
Due to the remarkable speed of both the eye and the Allegretto Wave® procedure, the laser beam will be constantly and minutely adjusted to the position of your eye at any given time. Every four to six milliseconds, the eye’s location is measured, and the internal mirrors of the laser are automatically aligned. Just before the pulse is released, a second check is made to confirm that your eye has not moved. If, at any time, your eye moves too quickly to be measured or moves out of range, the laser will stop and wait for your eye to move back into position.

Speed
Currently, the Allegretto Wave® Eye-Q Laser is the fastest vision correction lasers for LASIK available in the United States. For most patients, the actual laser application only takes 2-15 seconds, depending on the amount of correction necessary. Of course, spending less time under the laser means an easier and less stressful experience during your Laser Eye Surgery procedure.

Custom Wavefront Treatments
The Allegretto Wave® Eye-Q Excimer Laser Technology allows Drs. Stahl & Knowles to deliver a treatment shape using CustomVision™ that can both correct and optimize your vision through precise nomograms. CustomVision ™ with Allegretto Wave® Eye-Q Excimer Laser technology allows us to provide better night vision and glare control for our patients by creating a more precise corneal shape after your correction.

At Stahl Vision, patient safety & results are our top priority. While most of our patients are very pleased with their results, like all medical procedures, there are risks involved.

Nomograms for LASIK

Glossary: The Stahl Formula is an advanced nomogram that corrects the laser setting for each individual patient. Nomograms can correct for differences in patients such as age and gender, differences in technique or procedure such as between LASIK or PRK and differences in local conditions or seasonality such as humidity and laser calibration.

About Laser Eye Surgery Nomograms
One of the most critical factors that can affect your outcome after LASIK surgery is the nomogram that the LASIK surgeon uses. A nomogram is a unique group of detailed settings that is programmed into the laser for each patient. Some centers don’t use a nomogram at all. But the best results are achieved when your treatment is tailored specifically for you-for each person based on their age, gender, prescription, and dozens of other factors! And the very best nomograms come from years of experience, tens of thousands of patients, and honestly a lot of hard work.

Using this advanced technology, years of experience, and tracking the results of thousands of patients to fine tune results for each person based on their unique eyes. Dr. Stahl is achieving results among the top in the nation. With the Stahl Formula nomogram 99.3% or patients are 20/20 or better, and 81% are better than 20/20! *For many patients, this is better than they have ever seen with glasses or contacts, often with better night vision as well.

How Do We Create Our World Class Nomograms?
• First, we carefully control the laser suite climate-specifically the temperature and humidity, as well corneal hydration-to keep them constant.
• Then we use the very latest wavefront measurement technology to precisely analyze and monitor each patient before and after his or her Laser Eye Surgery. We use this both to develop their treatment plan and to track their results.
• By using computer modeling we correct for variables such as gender, age, the difference between wavefront measurements and conventional refraction, effect of correcting High Order Aberration on Low Order Aberrations such as nearsightedness, farsightedness and astigmatism and many other variables. From these calculations we are then able to create a “nomogram”.
• To implement and apply the nomogram, we use software designed and developed by Dr. Brian Stahl to customize an individual treatment plan for each patient.
• The nomogram is only as good as the laser used to deliver it, so we perform our Laser Eye Surgery procedures with our Wavelight Allegretto Wave® Eye-Q Excimer Laser using CustomVision™.
• Then we do it all over, and over and over-each successive nomogram becoming more accurate than the first. We never stop improving our results.
• If you are looking for this level of quality and attention to detail, then you won’t find anyplace better than here at Stahl Vision Laser Eye Surgery Center with Dr. Brian Stahl and Dr. James Knowles.

With yesterday’s technology, LASIK surgeons basically tried to help people achieve equivalent equal vision to what was obtained with their glasses or contacts. By using Wavefront technology and topography measurements to guide CustomVision™ treatments, vision can often be corrected beyond glasses and contacts. It’s the difference between regular and high definition TV- with CustomVision™, we are striving for High Contrast Vision.

Wavefront map guides the patient’s custom LASIK treatment.
The Wavefront measurement and topography measurements used to drive this technology is 25 times more precise than conventional methods used to take measurements for glasses and contacts. Using both technologies allows us to plan the very best treatment for your individual eyes. And when Coupled with the rapid tracking system of the Wavelight Allegretto Wave® Eye-Q Excimer Laser, this precise map or “fingerprint” of the eye can then be translated onto the surface of the eye rapidly and safety.

Night vision with custom LASIK treatments.
Many people wearing glasses and contacts complain about their night vision and don’t like to drive at night. One of the reasons for poor night vision is because of the tiny imperfections in their vision in addition to being nearsighted or farsighted. These tiny aberrations, which cannot be corrected with glasses or contacts, can cause disturbing problems like halos and glare with your night vision. With the marriage of wavefront technology and topography measurements, we are able to detect, diagnose and determine the ideal way to correct these aberrations resulting in better clarity and improving night vision. Patients are 4 times more likely to have an improvement in their night vision than a worsening with this advanced technology. Many patients are telling us they have never seen this well before.

But CustomVision™ doesn’t just stop there. By using advanced nomograms based on the results of tens of thousands of patients, and 20 years of experience, Dr. Stahl has taken our visual results to an even higher level! Our results far exceed those of the FDA trials, and exceed the results of other centers. By “fine tuning” the results for each individual person based on their unique eyes with our nomograms and using CustomVision™ technology driven with wavefront and topography guided LASIK, Drs. Stahl & Knowles are achieving the best results they have ever measured: 99.3% of patients are 20/20 or better, and 81% are better than 20/20!
*For many patients, this is better than they have ever seen with glasses or contacts.
