Abstract
It is well known that K-readings change as a result of keratoplasty producing either steepening or flattening of the anterior corneal curvature; these changes depend on the preoperative steepness of the host cornea and the extent of donor/recipient graft size disparity. Under these conditions the preoperative calculation of intraocular lens (IOL) power is very difficult to determine and IOL power formulas can predict postoperative refractive error within 2 D of desired power in only 26–62% of cases. Furthermore, in case of unclear media it is crucial to perform a careful examination of anterior and posterior segments with echography, before performing penetrating keratoplasty, especially if combined with extracapsular cataract extraction and IOL implantation. We report our experience in 32 consecutive cases of penetrating keratoplasty combined with ECCE and IOL implantation.
