[New generation of excimer laser--Asclepion Meditec MEL 70 G-Scan].

The new Asclepion-Meditec MEL 70 G-Scan represents a breakthrough in surgical application of excimer laser. The laser uses the latest generation of flying spot system which utilizes a SafeScan algorithm (patent pending) to avoid corneal surface irregularities. The system utilizes a Gaussian beam profile. In cases where the cornea has regular surface, the conventional excimer laser PRK or LASIK method will provide good results. If the cornea shows an irregular surface shape, custom-tailored, topography-based ablation, which has been adapted to the corneal irregularity, should provide better results. Asclepion-Meditec have added a TSA (Tissue saving Algorithm) module to TOSCA (Topography Supported Customized Ablations) software for carrying out topography-guided corrections. This module automatically minimises the tissue removal when calculating the correction program. MEL 70 G-Scan allows to treat all forms of refractive errors, myopia and myopic astigmatism -24 D sph, -12 D cyl, hyperopia and hyperopic astigmatism +16 D sph, +8 D cyl, mixtus and irregular astigmatism.
