Optical Biometry Versus Ultrasound Biometry [PDF]

open access: yesThe Egyptian Journal of Hospital Medicine, 2020
Background: Implantation of an intraocular lens (IOL) is the gold standard in modern-day cataract surgery. Over the last decade, IOL power calculations have become a focal point of cataract surgery. Objective: To compare the sensitivity and specification of optical biometry and applanation ultrasound biometry in the measurement of intraocular lens ...

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 ...
