Corneal aberrometer linked to laser shows promise for quality customized ablation
OCULAR SURGERY NEWS EUROPE/ASIA-PACIFIC EDITION June 2003
The CSO/Schwind system focuses on corneal aberrations, translating topographic maps into aberrometric maps.
A new system for customized ablation linking topography, aberrometry and laser is proving effective in treating corneal irregularities induced by previous surgery, “It’s an entirely new concept. Topographic maps are translated into aberrometric maps, which are able to give a precise image of what corneal irregularities produce in terms of image distortion,” said Ugo Cimberle, MD, at the winter meeting of the European Society of Cataract and Refractive Surgeons.The analysis of the corneal aberrometer focuses on the cornea rather than the entire eye, and this is the best and most reasonable choice possible,The cornea is the principal lens of our eye. Most image distortions come from there, and we work with the laser on its surface. Correcting aberrations on the cornea produced by other parts of the eye is, in my opinion, extremely improper, because it induces irregularities on the cornea and alters its natural conformation. We end up with a cornea that is worse rather than better,The system consists of the Eye-top (CSO), linked to the Esiris excimer laser (Schwind) through the ORK-W (optimized refractive keratectomy) program.
