Safilens launches new contact lens for presbyopiaSafilens has announced the launch of its new monthly silicone hydrogel contact lens for presbyopia called Open 30 Presbyo.

Like its predecessor, ‘fusion 1day presbyo daily,’ the new monthly contact lens uses an innovative afocal design which is patented by Safilens as the company believes it is “a veritable revolution in contact lenses for presbyopia.”

Safilens managing director, Vincenzo Bruno, said: “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 wellbeing.”

Mr Bruno added: “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 patients.”

The new contact lens is neither multifocal nor progressive, but features a small hyper-refractive central area that keeps paraxial optical rays out of the retinal image, according to Safilens.

A study on the new concept has been the focus of the company’s research and development department for the past three years, and its use and benefits are currently being studied in partnership with universities, including Aston in collaboration with the University of Rome, as well as other universities in France and Italy.

An afocal lens is said to increase the depth of field and consequently the width of the accommodation range. According to Safilens, unlike a multifocal lens that requires a complex cerebro-ocular adaptation process, with the Open 30 Presbyo no adaptation time is needed, since simultaneous vision is not involved in the process.

The ‘LacriMass’ 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 ‘fusiontechnology,’ the combined action of hyaluronic acid and tamarind seeds polysaccharide that normalises and stabilises the physiological relationship between the tear film and the surface of the eye, providing the wearer with natural, lasting comfort.

Additionally, the afocal design offers stable, clear and well-defined images under any light condition. Unlike multifocal lenses, 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.

An afocal lens also does not have any addition areas and therefore does not cause any aberrations that are typical with multifocal lenses, said Safilens.

Open 30 Presbyo is available with a 8.70mm base curve, 14.10mm diameter and powers ranging from + 6.00D to -6.00D.
