The eyeball method model is an intuitive teaching aid often used in ophthalmology teaching and clinical training, which can clearly display the external shape and internal structure of the eyeball. Its usage method needs to be carried out step by step and in a standardized manner.

First, place the model on a stable operating table and check whether the cornea, iris, lens, retina and optic nerve are intact to ensure it is convenient for demonstration.

When in use, you can start by observing the overall external structure of the eyeball, explain the morphological characteristics of the cornea and sclera, and then gradually break down the stratified parts of the model. Reveal the iris, pupil, lens and vitreous cavity in sequence, and focus on explaining their roles in imaging and visual function.

When continuing the operation, the connection between the retina and the optic nerve can be demonstrated to help learners understand the visual conduction pathway. In the teaching process, it is recommended to explain by combining Pointers or numbered marks to make it easier for students to establish spatial positioning and functional connections.

After the operation is completed, all components should be restored and properly stored to extend the service life of the model.

Through this model, students can have a more intuitive understanding of the anatomical structure and physiological functions of the eyeball, deepen their comprehension of common eye diseases such as cataract, glaucoma and retinopathy, and provide visual references for subsequent clinical learning and diagnosis and treatment.
