A new product from Morcher takes advantage of the pinhole effect to enhance depth of focus and will allow patients who have previously had cataract surgery with a monofocal lens a second chance to improve unaided reading vision if they missed out on the opportunity to have a multifocal lens at the time of their primary surgery.
The new implant has a 1.30mm central pinhole and is placed in front of the previously implanted monofocal lens. The pinhole aperture achieves 3D of near focus in the non-dominant eye and aids reading vision. The surgery is performed through a tiny 2.4 mm incision under local anaesthetic and would take less than 10 minutes to perform. It has the added benefit of being reversible with easy removal of the implant leaving behind the underlying intraocular lens in case of dissatisfaction.
Some patients may require additional YAG laser or laser eye surgery to achieve optimal vision.
