Graefes Arch Clin Exp Ophthalmol
July 2012
Background: Precise IOL calculation in post-refractive surgery patients is still a challenge for the cataract surgeon. The purpose of this study is to test whether adding Orbscan II values into the double-K method improves IOL calculation in this group of patients.
Methods: A prospective study with 43 eyes previously submitted to refractive surgery that underwent cataract extraction.
Purpose: To assess the outcome of Ferrara intracorneal ring segments for keratoconus.
Setting: Private practice and university hospital, Porto Alegre, Brazil.
Methods: In this retrospective noncomparative interventional case series, 51 keratoconus eyes of 47 patients that had Ferrara intracorneal ring segment implantation were reviewed.
