Problems solved by technology

One is to use balanced salt solution to moisten the cornea, but because it dries too quickly (generally 30S~60S), it is necessary to frequently use balanced salt solution during the operation, which will increase the operation time, and the droplets splashed on the surface of the lens will also affect the cornea. patient's vision
The other is to use corneal protectant, usually 1.5mL at a time, but the disadvantage of using corneal protectant is that it will cause distortion of the fundus image, and it needs to be applied every 20 minutes, and the operation time will also increase

Abstract

The invention discloses an intraoperative protective mirror. The protective mirror comprises an outer lens surface and an inner lens surface, and is characterized in that the outer lens surface and the inner lens surface consist of two arc surfaces; and the outer lens surface and the inner lens surface are connected into a whole to form a bowl-shaped transparent lens body. The invention also discloses an application of the intraoperative protective mirror in the vitrectomy. A method comprises the following steps of: finishing operation preparation, and smearing a corneal protective agent on the corneal surface; placing the intraoperative protective mirror above the corneal protective agent after the corneal protective agent is smeared; and after the contact surface of the intraoperative protective mirror and the corneal protective agent has no bubbles, carrying out the operation. The protective mirror can avoid or reduce the use of a balance liquid and the corneal protective agent, save the operation time, make images more clear in the operation, reduce the operation difficulty and improve the comfort level of the patient.

Description

technical field [0001] The invention relates to the technical field of ophthalmic medical device products, in particular to an intraoperative protective mirror and its application. Background technique [0002] In ophthalmic surgery, a clear fundus image in the surgical field is one of the most important factors affecting the surgical outcome. In modern ophthalmic surgery, wide-angle viewing system is widely used in ophthalmic surgery because of its advantages of providing a panoramic view of the operating area. There are two types of wide-angle observation systems, a contact system and a non-contact system. The contact system can provide better optical resolution and a wider field of view, but it is easily affected by the tilt of the patient's eyeball, which makes the stability of the fundus image extremely poor, thereby affecting the surgical effect. Non-contact systems are more widely and commonly used because of their image stability regardless of eye tilt and ease of ...
