Researchers at the Universitat Politècnica de València, University of Valencia, Instituto de Investigación Sanitaria La Fe and the companies AJL Ophthalmic SA and Aiken-Tecnología Ocular Preventiva SL have designed a new type of intracorneal inlay to correct presbyopia and farsightedness., according to a report in Medical Xpress.

The design is based on a diffractive with micro-holes that permit the flow of nutrients in the corneal stroma. Also, this new type of prosthesis allows doctors to customize the treatment of presbyopia (far-sightedness). Unlike its commercial counterparts, due to its high-efficiency, the prosthesis can be implanted in both eyes without producing binocular vision. The design is easily adaptable to the shape of the intraocular lens and contact lens.

According to Juan Antonio Monsoriu, researcher at Politècnica de València, standard treatment for farsightedness has included bifocal and progressive contact lenses, multifocal intraocular lenses, etc. The most current alternatives include the use of intracorneal inlays. However, "these prostheses are limited because of the reduction of the retinal image quality produced by the diffractive light passing through the micro-holes necessary for the proper flow of nutrients," says Juan A. Monsoriu.
