PDT Laser (Photodynamic Therapy Laser) is a specialized ophthalmic laser system used primarily for the treatment of choroidal neovascularization (CNV), particularly in conditions such as wet age-related macular degeneration (AMD), central serous chorioretinopathy, and ocular tumors. This therapy involves the use of a photosensitizing drug, typically verteporfin, which is activated by the laser at a specific wavelength—usually around 689 nm. Once activated, the drug generates reactive oxygen species that selectively damage abnormal blood vessels without harming surrounding healthy retinal tissue. The PDT laser system is designed for precision and safety, offering clinicians full control over the treatment parameters.
