Erratum in: “A Novel Intraocular Lens Simulator that Allows Patients to Experience the World Through Multifocal Intraocular Lenses Before Surgeries” by Kyung-Sun Na, Seong-Jae Kim, Gahee Nam, Minji Ha, Woong-Joo Whang, Eun Chul Kim, Hyun-Seung Kim, and Ho Sik Hwang (

After the article was published, the corresponding author requested that in the Discussion, the sentence “However, this device has a disadvantage that subjects experience flickering when they see the world through it, and the device does not test the real IOLs” be changed to “However, the device does not test the real IOLs.” This change has been made to the article online.
The author had thought that subjects experience flickering when they saw the world through it, but found that the subjects in fact do not experience flickering with this system: “Temporal Multiplexing is compatible with the physical limits of TLs and with the perceptual limits of the subjects. Measurements of the DTSF [Defocus Temporal Sensitivity Function] in subjects revealed that defocus variations at frequencies >40 Hz are not perceived. This bandwidth can be achieved by commercial TLs allowing multifocal visual simulators free of temporal artifacts” (Dorronsoro C, et al. IOVS 2019;60:ARVO E-Abstract 6465).
