白内障手術 – 水晶体超音波乳化吸引術下での核断片化 - 4K 映像素材

This close-up intraoperative photo captures a stage of cataract surgery, specifically phacoemulsification of a dense cataract. The image shows surgical instruments inside the anterior chamber of the eye. One handpiece is likely the phaco probe, which uses ultrasonic energy to emulsify the opaque lens nucleus, while the second instrument (chopper) assists with fragmenting and stabilizing the lens. Distinct star-shaped fractures are visible within the lens nucleus, indicating segmentation and emulsification in progress. The cornea and iris are retracted with a speculum, and reflections from the surgical light are visible on the corneal surface.
