This article describes the development and application of laser light sources in ophthalmic surgery, focusing on the excimer laser and the femtosecond laser. In addition to mechanical processing and semiconductor diagnostic instruments, the femtosecond laser applied on ophthalmic surgery has been a technology breakthrough. Our company has developed a "Femto-R1" eye surgery equipment, which integrates femtosecond laser and various technologies. This achievement not only competes internationally but also helps to enhance Taiwan's competitiveness in high-end medical device.
