• Resumen

  • One of the most important assessments for the success of cataract surgery or clear lens surgery is that residual refractive error after intraocular lens (IOL) implantation should be near to emmetropia. In order to do so, calculation of the IOL power should be as accurate as possible. A special dilemma arises in eyes that have previously had refractive surgery; either by corneal surgery or by a phakic IOL. The present manuscript offers a review of recently published studies that analyze and try to solve the problems to calculate IOL power in eyes with prior refractive surgery. The results reviewed in this manuscript show how IOL power calculation is a real problem in eyes that have had refractive surgery.

    Because it has yet to be proven which proposed method works best in all eyes, it behoves the surgeon to use as many methods as data are available and carefully evaluate the results
