Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a device for facilitating corneal wetting during cataract surgery. BACKGROUND

[0002] During the delicate and critical ophthalmic operation of cataract surgery, the wetting state of the cornea is crucial for the smooth progress of the operation and the postoperative recovery of the patient. Cataract surgery requires precise operation on the inside of the eyeball under a microscope. The cornea, as an important transparent structure in the anterior part of the eyeball, directly affects the clarity of the surgeon's field of vision and the precision of the operation.

[0003] A dry cornea will change the refraction of light on the surface of the cornea, causing the surgeon's field of vision to be unclear. In cataract surgery, the surgeon needs to rely on a clear field of vision to accurately determine the position and shape of the lens and the position of the surgical instruments. Any interference in the field of vision can affect the precision and safety of the operation, increasing the risk of complications such as posterior capsule rupture and zonular rupture, causing unnecessary pain and risk to the patient. In the traditional cataract surgery scenario, corneal wetting mainly relies on manual water application. When there is an assistant in the surgical team, the assistant can apply water to the patient's cornea in a timely and appropriate manner to maintain the wetting state of the cornea. However, there are many limitations in practice. On the one hand, many hospitals face a shortage of human resources, and it may not be possible to arrange a dedicated assistant to be responsible for the task of water application during the operation. On the other hand, even with the assistance of an assistant, due to the uncertainty of the surgeon's operation rhythm and progress during the operation, it is difficult for the assistant to accurately grasp the timing and frequency of water application, making it difficult to ensure that the cornea is always in an ideal wetting state.
