Patients with cataracts can choose from several types of artificial lenses, which are surgically implanted in the eye to replace cloudy lenses that obstruct vision. A new vision simulator could help these patients see how the world would look with each type of implanted artificial lens, before they have surgery.
In The Optical Society's journal for high impact research, Optica, researchers in Spain describe and demonstrate their new hand-held device called the simultaneous vision simulator, or SimVis. With SimVis, patients can experience how a certain implanted lens would affect their vision by simply looking through the device.
“There are many different intraocular lenses in the market, which provide different balances of near and far vision,” said Aiswaryah Radhakrishan, researcher at the Instituto de Optica, Consejo Superior de Investigaciones Científicas, Spain. “We have discovered a way to simulate these intraocular lenses and demonstrated a prototype device that allows patients to test different solutions before surgery and choose the one that best suits their needs.” Click to read more.
