Simultaneous Vision (SimVisGekko, 2EyesVision) is a visual simulator that provide patients with the experience of vision with multifocal intraocular lenses (mIOLs) before actual implantation, helping to manage patients’ expectations.
This innovation arose out of the scaling down of technologies that originated in astronomy, such as adaptive optics, into a system useful to ophthalmologists for prescribing correction for presbyopia and simulating multifocal lenses, according to Susana Marcos, PhD.
Despite the availability of mIOLs, she pointed out, only 7% of patients opt for this correction modality after cataract surgery.
Prof. Marcos, a research professor at the Instituto de Optica Daza de Valdés, Consejo Superior de Investigaciones Científicas, Madrid, said she believes that the key may be the difficulty explaining multifocality to patients.
In addition, it is difficult for patients to make a decision about mIOL implantation if they cannot visualize what their vision will be preoperatively, a scenario that leaves them with a great deal of uncertainty about both their expectations and the actual surgical results.
A solution to this may be use of the mobile SimVisGekko that would ease their decision-making process.
“Visual simulators will help to sell more premium lenses and screen out prospective unhappy patients,” Prof. Marcos explained. “This technology would be valuable for patients, clinicians, and IOL manufacturers.”
The device provides practical utility in the clinic, in that it improves patient satisfaction, facilitates comparison of corrective solutions, and saves time by providing an easy explanation of multifocality.
It also provides business advantages by reducing patient complaints and refunds, provides a competitive advantage to doctors who adopt the device early, and increases the number of mIOL prescriptions.
SimVisGekko is wearable, binocular, see-through, provides a 20-degree field of view, is programmable on a tablet and simulates multifocal and extended-depth-of focus corrections and provides monovision or modified monovision correction.
“This facilitates testing a range of preoperative corrections,” she pointed out.
