XPand 3D's Electronic Shutter Glasses Offer New Treatment for Amblyopia

By Eye² Staff


The common solution for treating children with amblyopia, or lazy eye, has been months of eye patching and the use of atropine drops, which has left many children untreated due to the long and demanding nature of the treatments. Now XPand 3D, a major supplier of 3D eyewear for cinema, home entertainment and gaming, is launching an innovative electronic eyeglass that treats children with amblyopia on the fly.

Externally, the glasses look like a normal prescription pair, but internally they feature an electronic shutter controlled by a preprogrammed microchip incorporated into the glasses frame. The microprocessor controls the shutter, creating short intermittent occlusions of the strong eye in order to treat the lazy eye without any difficulty or discomfort for the child.

XPand recommends that children should wear Amblyz throughout the day, regardless of the activity. The battery of the device should be recharged every night. The occlusion of the good eye will be performed automatically with prescribed intervals.

Amblyz glasses were developed by XPand in conjunction with ophthalmologists and optometrists. Clinical studies using an Amblyz prototype were conducted at three leading medical centers in Israel (Hadassah University Hospital in Jerusalem, Shiba Medical Center in Tel HaShomer, Israel and Meir Medical Center in Kfar Saba, Israel). XPand reports that the study results show excellent acceptance by children and parents of the LCG device. Further results also show that use is easy and compliance was high. Significant near and far vision improvements were observed as soon as five weeks into therapy. Overall results indicate high efficacy of the treatment (average of more than three LogMAR lines, comparable to best reported patching studies). No side effects were observed.

Amblyz glasses are available from select eyecare professionals.
