Abstract
Description
Technical Field
[0001] This utility model relates to the field of eye surgery instruments, and in particular to an eyelid opener. Background Technology
[0002] Cataracts refer to the clouding of the lens inside the eye, changing it from transparent to opaque, obstructing light from entering the eye and thus affecting vision. In the early stages, when the clouding is mild or covers a small area, it does not affect vision. However, it gradually worsens until it significantly affects vision or even causes blindness. Vision loss caused by cataracts cannot be corrected by wearing glasses, so surgery is required.
[0003] Currently, conjunctival sac effusion during cataract and glaucoma surgeries can impair the surgeon's surgical field and interfere with the procedure. During surgery, placing gauze strips along the lower eyelid margin is often effective in preventing conjunctival sac effusion; however, as the fluid flows and the patient's eyeball moves, the gauze strips frequently slip off and into the collection bag. Furthermore, some negative pressure suction eyelid speculums can cause postoperative dry eye after cataract surgery and have not been widely adopted. Summary of the Invention
