Safilens launches Open 30 Presbyo

February 10, 2016 Posted by Safilens


Safilens has announced the launch of its Open 30 Presbyo, a new monthly silicone-hydrogel lens for presbyopia. The new monthly, like its predecessor fusion 1day presbyo daily, uses an innovative afocal design patented by Safilens which is a veritable revolution in contact lenses for presbyopia: the lens is neither multi-focal nor progressive but features a small hyper-refractive central area that keeps paraxial optical rays out of the retinal image. The study of this new concept has been the focus of Safilens R&D department for the past three years, and its use and benefits are currently being studied in team with universities.
An afocal lens increases the depth of field and consequently the width of the accommodation range. Furthermore, unlike a multi-focal lens which requires a complex cerebro-ocular adaptation process, no adaptation time is needed, since simultaneous vision is not involved in the process. TheLacriMass™ design allows for non-uniform distribution of the tear film on the outer surface of the lens, increasing its thickness in the peripheral areas, where the major causes of eyestrain arise. The lens also benefits from the revolutionary fusiontechnology™: the combined action of hyaluronic acid and TSP (Tamarind Seeds Polysaccharide) normalizes and stabilizes the physiological relationship between the tear film and the surface of the eye, providing the wearer with natural, lasting comfort.
The result is a lens with extraordinary performance features: the afocal design guarantees stable, clear and well-defined images under any light condition. Unlike multi-focal lenses in fact, an afocal lens uses more than 90% of the light to put an image into focus and is not influenced by poor lighting or the dimension of the pupil. Last, an afocal lens does not have any addition areas and therefore does not cause any aberrations that are typical with multi-focal lenses. Open 30 Presbyo is available with an 8.70 mm. base curve, 14.10 mm. diameter and powers ranging from + 6.00D to – 6.00D.
“After the excellent results obtained with fusion 1day presbyo we just had to develop a monthly that had the same standard of visual comfort and well-being”, commented Vincenzo Bruno, Safilens Managing Director. “Afocal design offers multiple benefits: it prevents all the aberrations caused by stronger lenses, a reduction in the number of parameters (only 61), a simpler fitting process and easy adaptation also for the most demanding myopic patients”.
