[Intraocular lens (IOL) power calculation after keratorefractive procedures].
OBJECTIVE
To compare various methods of estimating corneal power for IOL calculation for cataract surgery after corneal refractive surgery.


METHODS
Review of the medical literature and case reports.


RESULTS
For more accurate IOL power calculations we need pre- (Kpre) and post-treatment keratometry records (Kpost) if using 3rd generation formulae, or Kpost records when using 4th generation formulae.


CONCLUSIONS
Prior to performing a keratorefractive procedure it is advisable to have pre-treatment refraction and keratometry (K and method) registered. 3rd generation formulae with Aramberri's double-K correction, or 4th generation formulae are recommended.
