Multifocal intraocular lenses for correcting presbyopia come out with new models from various companies every year. However, in the flood of information, there is not enough objective and good data to help our ophthalmologists decide which multifocal intraocular lens to use for their patients. When a new lens comes out, it takes a long time for large-scale clinical studies on that lens to come out. Of course, there are small-scale clinical studies conducted to get FDA approval, but since they are studies led by the lens company, this should be taken into account.
There are some cases where ophthalmologists and patients are disappointed because it is different from their expectations. Studies showing the defocus curve by taking pictures of the USAF 1951 resolution target through optical experiments come out relatively quickly, but they are taken in overly ideal environments (for example, using monochromatic light instead of white light, using high-contrast targets instead of scenes seen in everyday life), so they are different from what actual patients experience, and the results are difficult for patients as well as ophthalmologists to understand intuitively.
In this site, we implanted an actual intraocular lens into a mobile model eye developed by Professor Hosik Hwang and verified in a SCIE journal. We then photographed distant buildings (day and night) and nighttime scenes. To quantify the resolution, we approached the USAF 1951 resolution target continuously from 6 m to 15 cm. This objectively demonstrates how distant objects appear, whether they cause halo, glare and starburst at night, and what they look like at intermediate and near distances.
The Tecnis monofocal IOL as a reference (control group),the results of new multifocal IOLs such as Eyhance, Symfony, Synergy, Puresee, Vivity, Panoptix, Lisa tri, Gemetric, Intensity, Precizon presbyopic, and Precizon Go, Odyssey are objectively shown and compared to help ophthalmologists and patients choose a best multifocal IOL for their surgeries. However, be sure to consult with the ophthalmologist performing the surgery.
