The days when patients dare not question a doctor’s authority are definitely behind us.

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.

Many articles have been written about proper patient selection being critical for success with multifocal lenses. We're told to choose patients who have realistic (i.e., low) expectations, non-critical vision needs, and a history of diminishing success with monovision.
