Improving the treatment of corneal disease

: Italian researchers contributed to, in the Department of Ophthalmology at the University of Siena, in improving molecular surgical technique, known as "linking the Cruz" (Cross-Linking), for the treatment of keratoconus (Keratocone). Be infected tissues soft and weak and expand with time. Thus, the cornea loses its ability to collect light. Resulting in impaired visibility. In the absence of treatment, this disease soon turns into a disaster chronic health requires a new cornea transplant.

In terms of how this technique, the cornea is composed of a complex of tissue connected to each other through links eroded in patients with keratoconus. This gives the technique of the eye incentives for the restoration of these links are also consolidates the mechanical resistance of the eye. So we are talking about molecular surgery because we are not in front of traditional surgery but the treatment is designed to change the molecular structure of the cornea.

The cornea is treated with liquid is then shed a laser beam, ultraviolet, it. Process lasts one hour, maximum, and result in an improvement in visual capacity, except to stop the progression of the disease, temporarily.

Technology is being applied "for linking the cross" when the disease keratoconus in its first stage where there is a possibility to save the patient from blindness. As it should be the thickness of the cornea the patient's eye 400 micrometers, at least. Therefore, this technique include, in most cases, the sick children.
