Elipsys is a superior design based on research and 45 years of experience manufacturing GP lenses. From the outset the Elipsys system offers the simplest fit for both regular and irregular cornea offering a great deal of comfort.
GP contact lens system with eccentricity control and peripheral support
A clinical study carried out in 2003 with the aim of achieving an aspheric design that demonstrated that in visual acuity, comfort and contrast sensitivity was superior to any other aspheric design on the market today.
After a clinical study conducted over 18 months in 133 eyes and 79 patients of all ametropia in regular and irregular cornea with corneal astigmatism up to 2D, it is demonstrated under questionnaire in patients that it is a superior design for the following:
- Visual acuity: The key was to incorporate a spherical optical zone while variable aspherical optical zones offer lower quality of vision.
- Comfort: The key was in the adjustment of the eccentricity value to the population mean being ideal for different eccentricity values.
- Contrast sensitivity: The key was to adjust the values of optical zone and peripheral control to obtain the best relation in the lacrimal meniscus to optimize the best cornea/lens centering.
Spherical-spherical design on the posterior face with peripheral support control that allows a better corneal alignment optimizing the tear exchange, maintaining its centering and stability.
Multispherical geometry on the front face.
Indicated for patients from regular corneas to irregular corneas with keratoconus or other corneal ectasias.
Design with variable diameter optical zone that allows it to remain centered and stable in most irregular corneas.
The new concept of “peripheral support control” is ideal for corneas with different levels of eccentricity. Based on a statistical analysis a nomogram has been created identifying various eccentricity levels for different corneal conditions.
