| Summary: | The purpose was to review and document the methods used to calculate the power of the intraocular lens (IOL) to be implanted in cataract surgery in the specific scenario of eyes with keratoconus (KC). This review was conducted of all scientific articles published in English that focused on the parameters and formulas used to calculate the power of the IOL to be implanted in eyes with KC undergoing cataract surgery. There are few publications that show in detail how IOL power is calculated in those particular cases. If the keratometric value is used based on the standard refractive index (1.3375), this results in a postoperative refractive error with a tendency to hyperopia. The SRK/T formula is the formula yielding the best outcomes. The greater the severity of KC, the greater the deviation of the postoperative refractive status deviation from the target outcome. |
