A novel extended-depth-of-focus (EDOF) IOL (Mini WELL IOL, SIFI Medtech) is providing very favorable functional and safety outcomes that correspond with a high degree of patient satisfaction, according to data collected by ophthalmologists at the University Eye Clinic Heidelberg.
"We are finding that patients implanted with the Mini WELL IOL have excellent uncorrected visual acuity at far and intermediate distances along with very good uncorrected near visual acuity and a very low incidence of photic phenomenon," said Ramin Khoramnia, MD, assistant professor of ophthalmology, University of Heidelberg, and head, Refractive Surgery Department, University Eye Clinic, Heidelberg, Germany.
The lens is a biconvex multifocal aspherical IOL with a progressive optic featuring three zones. The central zone and a surrounding annular zone have spherical aberrations of opposite signs that create a continuous number of foci, and the external zone is a basic monofocal zone.
"The Mini WELL IOL provides quite sharp images at far and intermediate distances and near image quality is also quite good. In contrast, standard bifocal IOLs provide sharp images at far and near distances, but variable quality images at intermediate distance," said Dr. Khoramnia.
