GROW YOUR PRACTICE WITH WAVEFRONT TECHNOLOGY

Aberrometers like Coburn Technology’s Huvitz HRK-8000A are your first step in an aberrometry reading.

Wavefront aberrometry allows for a high rate of fitting success.

Contact lens materials and designs have continued to improve and evolve yet many eyecare professionals are not embracing the advancements and implementing them into practice.  When we look at the demand for toric and multifocal contacts, for example, we see a need that far exceeds utilization.

An estimated 25% of patients have astigmatism greater than .75D and could/should be fit in toric contact lenses An additional 56% of patients are presbyopic and have the need for mutifocal contact lenses. The actual percentage of patients wearing toric lenses is only 16%. For multifocals, it’s only 4%.

The way we see it: Our profession is underserving the needs of patients. That’s the bad news. The good news: This makes for a tremendous opportunity for practice growth.

EMBRACE THE NEW
Many of our colleagues have talked about the virtues of wavefront aberrometry in increasing speed, efficiency, and profit within their practices. We, too, are embracing this technology and have found it to be an invaluable tool in expanding our specialty contact lens practice.

We have used Optimized Wavefront Refraction (OWR) for surgical patients for years and are now utilizing this technology for Wavefront-Guided Contact Lenses (WFGCL). We’ve had some experience with the WaveForm Medical Lens in treating and correcting vision in patients with keratoconus and post-refractive surgery, so we were intrigued when we were asked to participate in a clinical study to evaluate a Wavefront-Guided Multifocal Contact Lens (WFGMFCL).

Our success rate in first-time fitting of the WFGMFCL exceeded 90%.  More impressive than the success, however, was the ease of the fitting process, with most of the fitting done by a trained technician.

FITTING PROCESS
Aberrometers like Coburn Technologies’ Huvitz HRK-8000A or Marco’s Nidek OPD 2-3 are your first step in an aberrometry reading. Next, a specially designed WaveForm diagnostic fitting lens is placed on the patient’s eye and allowed to settle for 10 to 15 minutes.

Another reading is then taken which measures the entire optical system including the diagnostic lens. A key point to note here is that the diagnostic lens has three fitting marks; during the second aberrometry reading these marks are analyzed relative to the pupil position.

The data is then transmitted to WaveForm and the proprietary software calculates and designs the needed lens that is then sent to a lathe cut so that a truly customized WFGMFCL is produced.

DESIGN SUCCESS
From a clinical and practical standpoint, the ability to design the contact lens optics to maximize centration over each individual’s pupil placement, along with identifying lens rotation, seems to be the key factor in fitting success. We also found that using the aberrometry data allows for better corrections for those patients with significant higher order aberrations. This is especially true for patients who complained of decreased vision under low light conditions such as nighttime driving and the patient who is 20/20 but still complains of blur.
