[0024] The specific application scenario of this embodiment is as follows: By setting an arc-shaped support base 130 inside the storage compartment 100 to provide support for the bottom of the covering sheet 220, the corneal covering 200 can be better protected during long-term storage, improving the stability of the corneal covering 200 during storage and preventing deformation and damage. It also provides good support for the bottom of the corneal covering 200. The corneal covering 200 has a cavity inside, which facilitates the storage of eye drops, thereby moisturizing the patient's cornea and improving comfort.
[0025] Example 2: As Figures 1-3The device includes a storage compartment 100, with an arc-shaped support base 130 on its inner wall. A corneal cover 200 is stored within the storage compartment 100. The corneal cover 200 is used for strabismus surgery. The corneal cover 200 has an internal cavity. A light-shielding plate 230 is located at the top of the corneal cover 200, and a cover sheet 220 is located at the bottom. Eye drops are stored inside the corneal cover 200. A top cover 120 is rotatably connected to the top of the storage compartment 100. A locking buckle 110 is rotatably connected to the outer wall of the front end of the storage compartment 100 via a pivot. A round rod 121 is fixedly installed on the outer wall of the front end of the top cover 120. The locking buckle 110 and the round rod 121 engage to lock the storage compartment 100 and the top cover 120.
[0026] The specific application scenario of this embodiment is as follows: by setting the storage compartment 100 and the top cover 120 together, the corneal cover 200 can be conveniently stored. By setting the latch 110 and the round rod 121 to lock, the corneal cover 200 can be conveniently locked and stored inside the storage compartment 100, thereby improving the protection of the corneal cover 200.
[0027] Example 3: As Figure 4 The device includes a storage compartment 100, with an arc-shaped support base 130 on the inner wall of the storage compartment 100. A corneal cover 200 is stored on the inner wall of the storage compartment 100. The corneal cover 200 is used for strabismus surgery. The corneal cover 200 has an internal cavity. The top of the corneal cover 200 is a light-shielding plate 230, and the bottom of the corneal cover 200 is a cover sheet 220. Eye drops are stored inside the corneal cover 200. An inlet pipe 210 is fixedly connected to the top outer wall of the corneal cover 200. The inlet pipe 210 is used to inject eye drops into the internal cavity of the corneal cover 200. An end cap 211 is threadedly connected to the top outer wall of the inlet pipe 210. A handle 240 is fixedly installed on the top outer wall of the corneal cover 200.

An inlet tube 210 is used to inject eye drops into the corneal cover 200. An end cap 211 seals the top of the inlet tube 210. The cover sheet 220 is made of polyvinyl alcohol and has the function of permeating eye drops. By setting the cover sheet 220, the eye drops in the cavity inside the corneal cover 200 can slowly permeate to the surface of the patient's cornea through micropores, thereby keeping the surface of the patient's cornea moist, improving the patient's eye comfort, and enhancing the protection of the patient's eyes.
[0029] The working principle of this utility model is as follows: When used by those skilled in the art, the locking buckle 110 is rotated to disengage it from the outer wall of the round rod 121. Then, the upper cover 120 is opened, and the end cap 211 at the top of the water inlet pipe 210 is opened. Eye drops are drawn using a syringe and delivered into the water inlet pipe 210, thereby delivering an appropriate amount of eye drops into the internal cavity of the corneal cover 200 through the water inlet pipe 210. During strabismus surgery on a patient, this is achieved through… Holding the handle 240, take the corneal cover 200 and place it over the patient's cornea, inserting it around the eyelids to cover the cornea. The micropores on the surface of the cover 220 allow the eye drops inside the cover 200 to slowly penetrate the cornea under gravity, preventing dryness when the patient cannot blink and improving corneal comfort.
[0030] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
