A new presbyopia contact lens, powered by Brien Holden Vision Institute’s Extended Depth of Focus technology has been launched by mark’ennovy.
Studies estimate that 1.8 billion people worldwide will be presbyopic by 2050.1 However, when faced with presbyopia, patients tend to drop out from wearing contact lenses.
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 size.2
Speaking of the new lens, Dr. Fabian Conrad from the Brien Holden Vision Institute comments, “The optimisation 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.”
Neil Goodenough, mark’ennovy’s Group R&D Director, said “The Brien Holden Vision Institute’s patented technology supports a comfortable adjustment to the EDOF, enhancing the overall wearing experience”.
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 available in a wide range of powers, diameters and base curves.
