How to improve IOL power calculations in keratoconusOne source of error in IOL power calculation is the use of the classical keratometric approach for the characterisation of the corneal optics. This approach is based on the assumption of only one corneal surface and a fictitious index of refraction (keratometric index, nk) for obtaining an estimation of the corneal power (Pk).
Study: Not all topography devices are alikeSubclinical haze after CXL can affect corneal topography measurements; a comparison shows that measurements with four different devices cannot be used interchangeably.
