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 of time. One company has the leading edge until another company 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 come up often in the news and in online discussion groups. Today, a new technology called the ScanFitPRO Scleral Lens, has grabbed all the attention, especially for Keratoconus patients who want to finally see clearly, and who also don’t have time for multiple visits to their Optometrist.

EyePrintPRO and ScanFitPRO Scleral Lenses

Do you have complex corneas? 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 the way you see the world.

EyePrintPro is a technology developed by EyePrint Prosthetics that literally takes a physical mold of your eye, much like a mold is made of your teeth at the dentists’ office. This very high precision 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 extremely accurate results and a very high rate of first-fit success: Where standard diagnostic tools result in patients requiring an average of 2.4 lenses (plus or minus 1 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 a material is placed directly onto the eye and allowed to cure. Despite the fact that it’s not as uncomfortable as it sounds and that it 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

Here at the California Keratoconus Center, we are a training center for the Eaglet Eye Surface Profiler. 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, Dr. Leonard custom designs the shape of the lenses and the landing area, which is where the lens will rest on your eye. The result is not only a more comfortable and easy to wear lens, but also a lens that fits perfectly more than 52% of the time.

But the folks at EyePrintPRO have been working with Eaglet to develop a method that takes the data directly from the Eaglet and feeds it directly into their own 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 in a first-fit success, and fewer visits to our office for a lens that works for the patient.

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 also had a shunt tube in her eye to help reduce the pressure in her eye. She also had no Iris, the colored part of the eye.

We presented her with a choice of many lenses, but the ScanFitPRO scleral lens was most ideal for her because the tube is very close to the cornea, causing a bump in her cornea. 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 for 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 types of 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.
