The aim of an accurate intraocular lens power calculation is to provide an intraocular lens iol that fits the specific needs and desires of the individual patient the development of better instrumentation for measuring the eyes axial length al and the use of more precise mathematical formulas to perform the appropriate calculations have significantly improved the accuracy with which the . The hill rbf calculator is an advanced self validating method for iol power selection employing pattern recognition and sophisticated data interpolation it has been optimized for use with the haag streit lenstar using optical biometry for all axial measurements and high density autokeratometry. Iol power calculations have become a focal point of cataract surgery formulas include barrett universal ii hill rbf olsen holladay hoffer q haigis srk t ladas the power of the intraocular lens implant can be calculated accurately when the corneal refractive power media type and axial length are properly measured. Iol calculation formulas explained when planning cataract surgery one of the most crucial stages for treatment success is choosing the correct intraocular lens iol power 1 to reach the targeted refraction the selection must be performed according to the anatomical and optical parameters of the eye 2 in most cases the target refraction is emmetropia but in some cases depending on the . Biometry is the method of applying mathematics to biology the term was originally used by whewell initially in the 1800s for calculating life expectancy the refractive power of the eye primarily depends upon the cornea the lens ocular media and the axial length of the eye when planning for cataract surgery in order to achieve the desired post operative refraction the required power of
