The SynergEyes VS scleral lens features scleral toricity and linear landing zones. The popularity of the scleral lens modality is colossal amongst specialty contact lens practices and continues to grow in general optometric practices. There are three major categories for scleral lenses: restoration and support of the ocular surface, visual rehabilitation and correction of corneal irregularity and pain attenuation.

This month marks the one-year anniversary of the launch of UltraHealth contact lens and thousands of patients are now benefitting from the vision, comfort and eye health that UltraHealth offers.

In this webinar, Dr. Jeffrey Sonsino talks about the new UltraHealth Hybrid Contact Lens, and how he uses it as an alternative to GP's and sclerals.

In Oklahoma, Denise Roddy, OD, of Tulsa, is known for her expertise in fitting specialty contact lenses. “Most patients referred to me have failed elsewhere,” Dr. Roddy says of the patients she receives from other corneal specialists including other ODs as well as MDs. Some patients, like one particular retired nurse educator whom Dr. Roddy saw recently, travel more than 100 miles for her care.

On-K fitting, or alignment fitting, is described as having the radius of curvature of the optical zone of the contact lens equal to the radius of the flattest K reading. This is one of the most straightforward methods of contact lens fitting. The goal in fitting Duette lenses is to have the GP portion parallel to the radius of the cornea, similar to the alignment fitting of traditional GP lenses.

For both UltraHealth and Clearkone, the fit (apical clearance) is determined for both lenses using a vault system. But the biggest difference between the two lens types, beyond the material composition, is the use of the skirts.

Shortly after UltraHealth was introduced, I became one of the top fitters of the lens in the U.S. We have a moderately busy keratoconus practice, seeing between 21-35 keratoconic patients per week among other complex anterior segment cases.
