Title	Improving outcomes of Customised Repair with a new platform: MEL 80 / Atlas
Abstract Nr.	145

Purpose	To develop and evaluate a new approach for repair of eyes after previous refractive Excimer laser surgery, combining Topography and Wavefront analysis
Methods	The calculation for the ablation patterns is done with a new Zeiss-platform for customization. The existing CRS-Master with the Shack-Hartmann-Aberrometer “WASCA” was completed with an “Atlas” Topographer. The calculation now is based upon Topographic AND Aberrometric information while taking the topographic picture as the master information but taking additional aberrometric information (e.g. the spherical aberration) of the whole eye into account. This enables the correction of corneal irregularities which are not described with sufficient resolution by aberrometers, and additionally improves the wavefront outcome of the eye
Results	Cases with decentrations, asymmetric cylinders, central irregularities and too small optical zones were selected to demonstrate the efficacy and safety of this platform. Results of the first eight treated eyes demonstrated a higher success rate than customized treatment based only upon topography. The subjective complaints disappeared in all but one eye. Topography Wavefront and BSCVA improved in 7/8 eyes. Results will be further analyzed in detail upon completion of the 3 months follow–up of twenty more treated eyes .
Conclusion	Customized laser, using a combined approach including Topography and Aberrometry data is highly successful and safe.
