Optometric technology advances much like other kinds of technology. It seems to happen slowly until we’re amazed at how far we’ve come in a short period. One company has the leading edge until another leapfrogs them with even better technology. With designing, manufacturing and fitting scleral lenses, the news changes frequently, and names like Zen Lens, Bostonsight, Eaglet Eye Surface Profiler and EyePrintPro often come up in the news and online discussion groups. Today, a new technology called the ScanFitPRO Scleral Lens has grabbed all the attention, especially for Keratoconus patients who want to see clearly finally and who also don’t have time for multiple visits to their Optometrist.

EyePrintPRO and ScanFitPRO Scleral Lenses

ScanFitPRO scleral lens

Do you have complex corneas? Are you tired of blurry vision, dry eyes, and poor-fitting contact lenses? Find out how the Eaglet Eye Surface Profiler and the ScanFitPRO scleral lens can change how you see the world.

EyePrintPro is a technology developed by EyePrint Prosthetics that takes a physical mold of your eye, much like a mold made of your teeth at the dentist’s office. This extraordinarily precise mold is then sent to the EyePrint labs, where they design custom scleral lenses based on the physical shape of your eye. Their method creates highly accurate results and a very high first-fit success rate. Where standard diagnostic tools result in patients requiring test fittings of an average of 2.4 lenses (plus or minus one lens) before arriving at a lens that is comfortable and works well for the patient, lenses based on EyePrintPRO impressions require an average of just 1.5 lenses (plus or minus 0.6 lenses).

One of the obvious drawbacks of this method is that it requires that the patient sit patiently while the mold material is placed directly onto the eye and allowed to cure. Although it’s not as uncomfortable as it sounds and produces extremely accurate lenses, the prospect of having this done is a deterrent for many patients.

How the Eaglet Eye Surface Profiler Improves on EyePrintPro

We are a training center for the Eaglet Eye Surface Profiler at the California Keratoconus Center. The Eaglet system improves steadily over time, not only with the innovations developed by their own scientists but by collaborating with other lens laboratories. With the free flow of information between Eaglet and Zen Lens, Bostonsight, and other companies, we can now profile a patient’s eye and get data on over 350,000 separate points on the cornea.

With the Eaglet data and the algorithms from the specific lens laboratory, our specialists custom design the shape of the lenses and the landing area, where the lens will rest on your eye. The result is a more comfortable and easy-to-wear lens and a lens with a 52% first-fit success rate.

But the folks at EyePrintPRO aren’t sitting still. They have been working with Eaglet to develop a method that takes the data directly from the Eaglet and feeds it directly into their lens lathe with almost no manipulation to create a ScanFitPRO scleral lens. If any adjustments are required, they are usually very minor, such as elevation or power.

The result of this combined Eaglet+ScanFitPRO process is a first-fit success equivalent to that of the EyePrintPro but with a no-touch scan instead of a physical mold. For the patient, that means a greater chance of first-fit success and fewer visits to our office for a lens that works for them.

ScanFit Scleral Lenses Are Ideal For Complex Corneas

We recently saw a young 15-year-old woman who had had a severe eye infection one year ago that caused severe ectasia, a condition where the cornea changes shape, becomes very weak, protrudes, and distorts the patient’s vision. She had a shunt tube in her eye to help reduce the pressure and had no iris, the colored part of the eye.

We presented her with many lenses, but the ScanFitPRO scleral lens was ideal for her because the shunt tube is very close to the cornea, causing a bump in it. Our design of her lens included a small wave of the lens over the bump to prevent contact and avoid complications with the shunt. We also made her an additional soft contact lens with an artificial iris so that, cosmetically, her eyes looked the same.

Will A ScanFit Lens Work For You?

Do you have complex corneas? Have you been unable to achieve clear, trouble-free vision with other conventional or scleral lenses? Then the ScanFitPRO Scleral Lens may be perfect for you. That said, a ScanFitPRO Lens is only as good as the prescription made for it. And at the California Keratoconus Center, we specialize in designing scleral lenses with the Eaglet Eye Profiler. If you are ready to see clearly or have a few questions, call the Center today at 818-891-6711 and ask to speak with one of our Keratoconus specialists. Or make an appointment online.
