About Us

Our Story

NVI was founded by Dr. J.T. Lin, the inventor of flying-spot LASIK a procedure currently used in ALL eye hospitals worldwide. Dr. Lin is also the founder and CEO of LaserSight, Inc. (a Florida company, listed in NASDAQ in 1991).

NVI has office at Taipei (Photon Medical, Inc.), R&D Center (Medical Photon Tech, Corp) and factory at the BioScience Park, Xiamen, China. It has awarded by 3 Projects supported by Xiamen-200 Program since 2013.


The Company core technologies include (covered by over 15 patents): diode lasers for dental, cosmetic and ophthalmology applications, nano-tech for laser-assisted cancer therapy, and low-power laser for photodynamic therapy.

NVI currently offers many new products under the model names of: UV-360, UV-310, EYE-800, DEN-800, CN-800, Lit-600 and IR-1500. The Company currently has on-going clinical trials in China and USA for various new protocols.

Dr. Lin has the following world record in medical system designs
