ESSential Multifocal
Description
The ESSential GP Multifocal family is a series of lenses that simplifies multifocal fitting by combining the best attributes of simultaneous and translating multifocal designs.
Family includes ESSential GP multifocal and ESSential Xtra, with the option of adding a front-surface annular component called a concentric S-form add (CSA) enhancement to either design.
The ESSential family simplifies the process of fitting multifocals and meets the needs of a variety of patients - including not only presbyopes, but also myopes, hyperopes and astigmastic patients – while being able to easily transition from contact lenses to spectacles. In addition, emmetropes and near emmetropes, are often perceived as difficult to fit, but these patients can achieve good vision at distance, intermediate and near with ESSential lenses.
Series I features the least amount of eccentricity and the largest optic zone. It is appropriate for early to intermediate presbyopes with +1.25D aspheric power gradient.
Series II provides an ADD zone closer to the center of the lens for more ADD power. Gradient generates 1.50 to 2.00D for near to intermediate vision.
Series III has the greatest amount of eccentricity and the ADD zone begins the closest to the center of the lens, providing the smallest optic zone. Series III offers +2.25 to 2.50D of ADD power.
- Empirically Fit - No trial sets needed.
- Utilize an alignment fitting philosophy that ensures long-term corneal integrity and stable vision.
- Can be a translating or simultaneous back-aspheric lens with low eccentricity to help prevent corneal molding.
- The uniformity of the aspheric design gives you the ability to transition your patients from one series to the next with consistency as their near needs advance or change.
- "S-Form Technology," a proprietary manufacturing process, produces a smooth flattening effect that creates a greater posterior power gradient and a greater near point power effect, while providing better contrast sensitivity. S-Form provides ADD correction from +0.75 to +3.00D depending on the series selected.
- Concentric S-Form Add (CSA) can be added to the anterior surface of the lens with 3 various distance zones and up to a combined ADD correction of +4.00D when more ADD power is needed without compromising intermediate or distance.
Presbyopes, Myopes, Hyperopes, and Astigmats
Standard base curves range from 6.90 to 8.30mm and diameters from 8.8 to 10.5mm
