The femtosecond laser cataract correction device is a next-generation femtosecond laser cataract surgery instrument that combines 3D imaging and navigation technology to analyze eye structures and create a three-dimensional eye map to assist with precise calculations and predictions for surgery. The new femtosecond laser-assisted cataract surgery uses a fully computer-controlled infrared laser to perform three steps, including corneal incision, capsulotomy, and lens fragmentation. This allows doctors to perform precise incisions and evenly fragment the lens, resulting in more accurate implantation of artificial lenses and improving the accuracy and postoperative visual quality of multifocal lenses. This new technology is safe, reliable, and highly accurate, reducing the risk of surgical trauma, postoperative infections, inflammation, and other complications.
