The optics laboratory designed lenses with technology of space telescopes able to reduce up to in a 40% blindness caused by degeneration age related macular.
The magazine 'Biomedical Optical Express' just presented this technological breakthrough that enables a surgical treatment against the leading cause of total loss of eyesight in older of 55 years. The minitelescopios iolAMD, designed by the team of Professor Pablo Artal in collaboration with Dr. Qureshi of the London Eye Hospital Pharma, implanted in ten minutes and without the need for sutures to be the first manufactured with a flexible material.
Thousands of affected age-related macular degeneration (DME) You can again lead, read, watch television and recognize faces thanks to the latest optical development created by the optics laboratory of the University of Murcia (LOUM). The research team directed by Pablo Artal, Professor of optics and renowned world expert in Adaptive Optics, has served its own space telescope technology to create intraocular lenses capable of reducing the progressive and irreversible vision loss suffering from those affected by the serious eye disorder.
Macular degeneration associated with age is the leading cause of blindness in adults of 55 years in Western countries, with more than 25 millions of patients around the world. The patient loses central vision by damaging the blood vessels that supply the macula, an area of the retina that is responsible for our sight is more sharp and can appreciate the details. Patients with DME in acute phase were doomed to blindness to the absence of an effective and safe drug or surgical treatment. Until today.
The prestigious scientific journal 'Biomedical Optical Express' describes in its latest issue the technological advance that the physicist Pablo Artal research team has developed for the minitelescopios in close collaboration with Dr. Qureshi, Director and founder of the famous London Eye Hospital (United Kingdom). The purpose of this famous ophthalmologist was to intervene to DME affected using the same type of microsurgery used in cataract operation.
Inspired by Galileo Galilei
"We are inspired by the first telescope which Galileo Galilei built in" 1609 to demonstrate that the earth revolved around the Sun. It is a refractive telescope, with a positive lens and other negative. Starting from there solved the problems presenting other optical procedures failed to treat the DME also played Galileo telescope. The main advantage of bringing our lenses is that we have been able to manufacture them with a flexible material, It is injected into the eye through a small-incision so that it does not require sutures, which significantly reduces the risk of infection and postoperative complications. It's like make the leap from an operation open heart to a cut of the size of a lock slot", detailed teacher Artal.
Another of the innovations that make these minitelescopios a promising treatment involves the application of modified optical. Professor Artal points out that "iolAMD lenses moving vision of the patient to the peripheral area of the eye, avoiding the damaged central area. In this way, the patient controls their vision without the need of turning your head sharply whenever he focuses on an object and, In addition, advanced optical design solves serious problems of adaptation to peculiarities that owns each eye", detailed teacher Artal.
Currently are being carried out clinical trials in more of 200 patients from the United Kingdom, Germany and Italy. The recipients of these innovative minitelescopios have experienced an improvement in vision of between a 20% and a 40%, According to preliminary data that manages the London Eye Hospital. Professor of optics of the UMU stresses that "it is not a cure, but return that percentage of vision a person with DME may mean to give you the opportunity to drive or read". However, the final results of these clinical trials will validate soon with its publication in accredited journals.
