Refractive surprise after cataract surgery secondary to smeared optics of swept-source optical coherence tomography biometer: a case report

open access: yesBMC Ophthalmology, 2020
Background Inaccurate biometry can lead to the wrong intraocular lens implantation and result in refractive surprise following cataract surgery. It is important to be sceptical of biometry results that do not match the refractive or clinical picture and ...

Evaluation of Wang-Koch optimisation of axial length for intraocular lens power calculation in myopic eyes

open access: yesAfrican Vision and Eye Health, 2022
Background: Refractive outcome has become more relevant in myopic patients. Refractive surprises are mainly caused by errors in axial length (AL) measurement.
