According to Verdict, a new wearable vision simulator called the SimVis can help cataract patients virtually experience how cataract surgery will improve their vision.
Cataracts are a leading cause of vision loss that affects more than 24 million Americans age 40 and older. Cataract surgery is one of the most common surgeries performed today and restores vision in the majority of patients. In a simple, 30-minute outpatient procedure, a surgeon can replace the clouded lens with a clear, artificial lens called an intraocular lens (IOL).
Preview Your IOL with SimVis Visual Simulator
Scientists at the Spanish National Research Council (CSIC) created the SimVis so cataract patients could get a realistic idea of what their vision would be like after cataract surgery. The SimVis can mimic the effects of a multifocal intraocular lens (IOL), which allows patients to see clearly at several distances. Although the SimVis is not yet commercially available, the device has exciting possibilities for cataract surgery candidates as well as surgeons.
CSIC researcher Susana Marcos and her team at Visual Optics and Biophotonics Laboratory, Spain, have extensively researched vision simulation devices. Because the SimVis is non-invasive, Marcos believes the device may ease patients’ fears of cataract removal and will help “to reduce uncertainty and to manage expectations” (Novuslight).
How SimVis Vision Simulator Works
The SimVis is an adaptive optics (AO) vision simulator that uses mirrors, lenses and light modulators to mimic various types of intraocular lenses. The wireless, lightweight headset can be worn alone or in a helmet. Through a program launched through a mobile app or tablet, surgeons can test patient preference of specific lenses and make accurate recommendations for IOLs.
Additional details about the SimVis technology are published in the February 7, 2019 issue of Scientific Reports.
