Technical Field
The present utility model relates to an ophthalmic lens protector, and in particular to an ophthalmic lens protector for fundus oculi retinal examination.
Background
The lenses such as the three-sided mirror, the holotoscope and the gonioscope are commonly used auxiliary diagnosis and treatment equipment for ophthalmology, and by means of different types of lenses, a clinician can observe various eyeground and glaucoma related diseases, including the range of retinal detachment, the positioning of retinal holes, the understanding of anterior chamber angle conditions and the like, and in addition, the lenses can assist in completing retinal laser photocoagulation under surface anesthesia and the like, so that the lens is an indispensable important tool used every day in daily clinical work of ophthalmologists. However, the lens needs to be contacted with the face, conjunctiva and cornea of a person through the couplant during the use process, and cross infection risks can be brought to the person to be inspected if the lens is not properly sterilized.
The conventional method adopted for disinfecting the lens is to wash with running water and match with glutaraldehyde for soaking. However, this sterilization method has the following adverse effects: 1. repeated cleaning can cause damage to lens friction of the lens, so that the permeability and definition of the lens are reduced, and the observation effect is affected; 2. long glutaraldehyde soaking can cause liquid to penetrate into the lens and damage the lens; 3. if the cleaning is insufficient, the residual disinfectant may damage the eye surface structure of the inspected person, resulting in accidental injuries such as facial inflammation, keratoconjunctivitis and the like; 4. because a long time of soaking is required to achieve the disinfection effect, the clinician and the person to be examined consume a lot of waiting time, and the working efficiency is low.
Therefore, finding a simpler and more convenient method to achieve disinfection or protection of lenses is a problem that needs to be solved in the clinical use process of lenses at present. The utility model aims to design a protection device, which can protect the lens on the basis of not affecting the observation effect of the lens, and can prevent the lens from directly contacting with the eye body, so that the lens is used for one lens, is convenient to use and replace, and can effectively prevent the risk of cross infection possibly caused by the direct contact of the lens with the eyes of a person.
