QD Laser is a Japanese medical device and semiconductor company that specializes in the development of quantum dot laser technology for healthcare and industrial applications. In the healthcare sector, the company is primarily known for its Visual Support business, which produces the RETISSA series of retinal projection laser eyewear designed to assist individuals with visual impairments. This innovative technology projects images directly onto the wearer's retina, bypassing the eye's optical system and providing clear vision regardless of the condition of the cornea or lens. Beyond assistive eyewear, QD Laser develops laser-based diagnostic tools for ophthalmology, including fundus imaging and visual field testing devices. The company's core expertise lies in the mass production of high-performance semiconductor lasers, which it leverages to create unique solutions for vision correction and ophthalmic diagnostics.
