Abstract
While corneal refractive surgery produces excellent visual outcomes, the changes it produces in anterior corneal curvature make it more difficult to accurately calculate corneal refractive power for intraocular lens (IOL) calculations. The development by Hill, Wang, and Koch of the ASCRS online calculator in 2007 facilitated more accurate IOL power calculations in eyes that have undergone corneal refractive surgery. Since then, novel techniques such as optical coherence tomography (OCT) have been utilized to further improve IOL power calculation accuracy.
The following chapter discusses the preliminary results of one such study presented by Wang et al. at the annual ASCRS meeting in 2013. Their prospective study included a group of 28 eyes of 24 patients at one institution enrolled between November 2010 and March 2012. The study validates the OCT-based IOL power formula developed by Tang et al. and compares it to methods using the ASCRS calculator.
