Importance of Performing Corneal Topography Before Cataract Surgery

Abstract

Corneal topography assessment has become increasingly important for surgical planning in patients scheduled for cataract surgery. One of the main reasons is the increased expectations for reduced spectacle dependence following cataract surgery, whether patients are selecting an advanced technology intraocular lens (ATIOL), such as a toric or multifocal IOL, or even when choosing a monofocal IOL Preoperative topography enables surgeons to determine whether a patient is an appropriate candidate for an ATIOL, and also enables surgeons to identify corneal conditions that are contraindications to certain types of IOLs, especially as many corneal conditions are not visible on slit lamp exam. This article will focus on the value provided by preoperative corneal topography prior to cataract surgery and discuss clinical situations where it has been critical in guiding IOL selection.
