ABSTRACT

The intraocular lens implant marked a great breakthrough in the cataract surgery, allowing the optimization of the refractive results of the patients. Intraocular lens power calculation has greatly improved during recent years. However, achieving the emetropia in some situations has become a real challenge for surgeons, because the number of cataract patients, who go every day to the ophthalmological service with previous cornel refractive surgery, is increasing. The calculation of the intraocular lens power for those eyes that have experienced corneal refractive surgery will be a matter under permanent discussion until we can rely on a method capable of directly measuring the corneal power following radial keratotomy or photoablative procedures. As an alternative for treating these patients, several authors have added multiple algorithms to avoid the refractive surprise. A literature review was made with the aim of describing the main methods to calculate the intraocular lens power post corneal refractive surgery depending on the available data.
