A selective photodisruption system for the prevention and treatment of after cataract
The selective photoremoval system utilizes high-resolution imaging and adaptive energy-controlled laser technology to selectively remove lens epithelial cells and fibers, solving the problems of prevention and treatment of polymorphic keratitis (PCO) in existing technologies, reducing the incidence of PCO and avoiding structural damage and complications, thus providing non-invasive treatment.

AI Technical Summary
Existing technologies for the prevention and treatment of secondary cataracts (PCO) suffer from poor preventive effects and excessively high treatment costs. In particular, Nd:YAG laser posterior capsulotomy carries unavoidable risks of structural damage and complications, while pharmacological interventions have risks of cytotoxicity and insufficient target specificity. Materials science improvements have not been able to effectively prevent the occurrence of PCO.
The selective photoremoval system includes a high-resolution imaging module, a pulsed laser source, and an adaptive energy control module. It identifies target tissue through high-resolution imaging, generates a three-dimensional laser scanning path, and uses pulsed laser to selectively remove lens epithelial cells and proliferating fibers, ensuring that the integrity of the posterior lens capsule structure is not damaged, while controlling the energy within the energy window.
It achieves selective removal of diseased tissue without damaging the lens capsule structure, fundamentally prevents PCO, reduces the incidence, avoids the risks of Nd:YAG laser, and provides truly non-invasive treatment results.
