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

BMC 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 ...
