From Dr Edmondo Borasio:
The 1st and most advanced App for Ophthalmologists released for the iPhone/iPod Touch/iPad! A must-have tool for all Anterior Segment surgeons. EYE PRO 2011 includes Astig PLOT! (The previous version, "Eye Pro" has only got the Trial version) ** QUITE SIMPLY, THE MOST ADVANCED AGGREGATE ASTIGMATISM PLOTTER ON THE PLANET! **All the features of the old Eye Proand much more! Check out all the screenshots at: www.edmondoborasio.com.FEATURES:Astig PLOT (AMAZING NEW TOOL!): Create amazing astigmatism plots for congress presentations or scientific paper submissions! Plots aggregate astigmatism data on an autoscaling doubled-angle polar plot! Shows each individual astigmatism and the mean on the plot Calculates and shows the Mean Astigmatism and SD (after conversion to cartesian notation) Calculates Surgically Induced Astigmatism (SIA) and SD Plots the astigmatism centroid Send plot via email Files can be read from URL or via iTunes (PC or Mac)AstigMaster: Calculates the Surgically Induced Astigmatism vector (SIA) for single patients, either using K values or Refractions. Also shows the cartesian (X;Y) conversion of the SIA vector.Standard Biometry: SRK/T, Hoffer Q formula (correct versions approved by their Authors)Biometry post Laser Refractive Surgery: BESSt 2 Myopia, BESSt 2 Hyperopia, BESSt 1 formula (1) Double K adjustment for SRK/T, Hoffer Q, BESSt 1Visual Acuity Converter: Converts VA between LogMar, Snellen and Decimal notationCorneal / Spectacle Plane Converter: Converts Refractions between Corneal and Spectacle Plane for any given BVDCartesian / Polar Notation Converter (2) Converts Astigmatism and Axis (or Meridian) from the traditional Polar Notation (e.g. +3.25 x30 Degrees) to Cartesian Notation (e.g. X=1.63; Y=2.81) which is essential if you want to average multiple refractions for statistical analysis.Optical formulas: Thick Lens Equation (Gaussian Optics Formula) Thin Lens Equation (to convert from Ant r to CP and viceversa) Custom Keratometric Index-based calculationsAstigmatism correction reduction calculator: Predicts the final astigmatism following incision or Toric IOL misalignmentToric IOL calculator: Estimates the axis of an implanted Toric IOL starting from pre an post-op refractionsNotes:(1) BESSt 2.0 formula (Myopic / Hypermetropic algorithm): the latest version of BESSt allows more accurate estimation of IOL Power in eyes which underwent Laser Refractive Surgery for either Myopia or Hypermetropia. BESSt 2.0 only requires Pentacam measurements, without ANY need of pre-refractive surgery information. (2) This amazing tool is ESSENTIAL for statistical analysis and allows to easily convert each Refraction from the classical Polar notation (e.g. +3.25 x 30 Degrees) to Cartesian notation (e.g. X=1.63; Y=2.81) in order to perform standard statistics such as Average and SD on a group of eyes. The final result can then be converted back to traditional Polar notation for descriptive purposes.
