WAIKOLOA, Hawaii — Swept-source OCT and total keratometry can help improve IOL calculations in patients who have previously undergone laser vision correction, according to a presentation here.
At Hawaiian Eye 2022, Preeya K. Gupta, MD, said there are several reasons why a post-refractive cornea can cause problems when determining which IOL to use.
First, there is a keratometric index of refraction error caused by some calculation techniques.
“1.3375 is used to convert the radius of anterior corneal curvature into diopters,” she said. “The problem is that it assumes a
