Why is presbyopia such a big deal? Currently, in Europe alone, there are around 340 million people over the age of 45 in need of some degree of correction for near vision1. Studies estimate that 1.8 billion people worldwide will be presbyopic by 20501. However, considering contact lens wear, presbyopia tends to increase patient dropout.

For most eye care professionals, the problems associated with multifocal contact lenses are obvious: reduced contrast sensitivity, undesirable ghosting and diminished low-contrast visual acuity, engendered by a well-known set of factors, including the centration, design and near add power of the contact lens, as well as to the patient’s spherical aberrations and pupil size2.

Despite these issues with multifocal contact lenses being common knowledge among professionals, it remains a challenge for even the most experienced fitters to stop their patients from complaining and ultimately dropping out of their lenses due to inadequate vision.

mark’ennovy, leading independent provider of precision contact lenses, and the Brien Holden Vision Institute, world-renowned non-profit organisation for innovative vision care solutions, have teamed up to develop EDOF, a brand-new soft contact lens for presbyopes. The monthly individually crafted silicone hydrogel lens, powered by the Brien Holden Vision Institute’s patented Extended Depth of Focus technology, is positioned to take on the shortcomings of other multifocal soft contact lenses.

Dr. Fabian Conrad from the Brien Holden Vision Institute comments, “The optimization of higher order aberrations having taken into consideration different pupil sizes, decentrations and aberrations support clear vision at all distances minimising unwelcomed visual disturbances like ghosting and haloes.”

 

“The Brien Holden Vision Institute’s patented technology supports a comfortable adjustment to the EDOF, enhancing the overall wearing experience,” states Neil Goodenough, mark’ennovy’s Group R&D Director.

 

EDOF comes to market alongside MYLO, a new soft silicone hydrogel lens specifically for Myopia Management, also powered by the Brien Holden Vision Institute’s patented Extended Depth of Focus technology. Both lenses are now available in a wide range of powers, diameters and base curves.
