Intrastromal Correction of Ametropia by a Femtosecond Laser

2014-07-23 21:14:05 | BioPortfolio


This study evaluates the intrastromal correction of ametropia with a femtosecond laser made by 20/10 PERFECT VISION. This laser generates a beam of ultrashort, infrared pulses which enables very precise cuts in the cornea. By these cuts lamellae of the cornea are separated locally, and in the consequence the curvature of the cornea is changed, and the correction of the diagnosed ametropia can be achieved. On the contrary to cuts which are generated with a sharp knife, the cuts generated when using a laser can be generated just inside the cornea without opening the surface of the cornea. This means the procedure is minimal-invasive.

The study hypothesis is: Different types of ametropia can be corrected safely and on long-term by intrastromal cuts.
