EYECOS Clinic has developped a revolutionary laser technique to correct forever the Iris Congenital Heterocromy. Neweyes is safe, effective and natural. This outpatient treatment is applied in only 5 to 7 days, using 5 minutes painless laser sessions. It is not a surgical procedure, with intraocular implants, wounds, healing, stitches and risk of infection, NEWEYES is only laser, where anesthetic drops are enough to avoid discomfort.
Since January 2012 we use successfully Neweyes, with very high satisfaction levels and extremely low complications, because no visual structure is altered. After treatment patients never complain of photophobia, discomfort, red eyes, or bad vision.


In the past, EYECOS was also world pioneer introducing since 2000 PRESBILASER, a lasik procedure to correct Presbyopia, the most frequent refractive error after forties. PRESBILASER eliminates the need of reading and multifocal glasses, and is also an outpatient technique, without typical risks of surgical procedures, only laser with topical anesthesia. Patients can recover normal life after one day. Now, PRESBILASER has been adopted by all the ophthalmolgy clinics, as a routine technique in Spain.
