Through objective and impartial intraocular lens testing, our Visual Optics platform
provides ophthalmologists with the reference materials they need to select the optimal IOL for their cataract surgery patients.
However, amid the flood of information, there is not enough objective, reliable data to help ophthalmologists and patients decide which multifocal IOL to use.
When a new lens is launched, large-scale clinical studies on it take quite a while to appear.
There are small-scale clinical studies conducted to obtain FDA approval, but since they are company-led studies on that lens, this has to be taken into account.
Sometimes a surgeon implants a lens based only on the manufacturer's explanation, and the outcome differs from expectations and disappoints; the ophthalmologist can simply use a different lens next time, but the patient is left bewildered.
Studies that photograph the USAF 1951 resolution target and show defocus curves through optical experiments come out relatively quickly, but they are taken under overly ideal conditions (for example, monochromatic light instead of white light, and high-contrast charts instead of everyday scenes), so they differ from what real patients experience and are results that even clinicians, not just patients, find hard to grasp intuitively.
On this site, we insert IOLs currently on the market into a portable model eye (mobile model eye), developed by Professor Ho Sik Hwang of the Department of Ophthalmology, Catholic University of Korea, and validated through publication in an SCIE journal, then photograph distant buildings (day, night) and night streets, and to quantify resolution we photograph the USAF 1951 resolution target while continuously approaching from 6 m to 15 cm. Through this, we aim to objectively show whether distant objects appear hazy as if fogged, whether there is spreading at night (light spread, halos, glare), and how things look at intermediate and near distances.
Using the currently available Tecnis monofocal IOL (ZCB00) as the reference (control), we objectively show and compare the results of new IOLs such as Eyhance, Symfony, Synergy, Puresee, Vivity, Panoptix, Lisa tri, Gemetric, Intensity, Precizon presbyopic, Precizon Go, and Odyssey — including diffractive multifocal, refractive multifocal, continuous-focus, and extended-depth-of-focus IOLs — to help ophthalmologists and patients choose the IOL for cataract surgery.
However, be sure to consult the ophthalmologist performing your surgery.
