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 ...

Femtosecond laser-assisted cataract surgery compared with phacoemulsification: the FACT non-inferiority RCT.

Health Technology Assessment, 2021
BACKGROUND Cataract surgery is one of the most common operations. Femtosecond laser-assisted cataract surgery (FLACS) is a technique that automates a number of operative steps. OBJECTIVES To compare FLACS with phacoemulsification cataract surgery (PCS).
