In 1851, helmholtz in Germany invented ophthalmoscope, which was truly independent of ophthalmology and became a subject.

The most common ophthalmic diseases in ophthalmology are: central serous retinopathy, dry eye, sympathetic ophthalmia, nyctalopia, blindness, amblyopia, astigmatism, trachoma, cataract, diabetic retinopathy, conjunctivitis, presbyopia, achromatopsia, iridochromism, retinitis pigmentosa, central retinal artery occlusion, retinal detachment, myopia, hyperopia, pinprick, snow blindness, aragonima, glaucoma, muscae volitantes and the like.

For the above ophthalmic diseases, many diseases need to be treated by surgery, and the common ophthalmic surgery types are: ophthalmic eye plastic surgery, ocular surface surgery, glaucoma surgery, lacrimal surgery, ocular tumor surgery, excimer laser treatment of myopia, cataract phacoemulsification surgery, foldable intraocular lens implantation, multifocal intraocular lens implantation, intraocular lens implantation with iris, etc.; orbital tumor surgery, treatment of thyroid-related eye diseases, implantation of hydroxyapatite artificial eye seats, assembly of artificial eyes, vitreous body with high ophthalmic difficulty, retinal surgery, treatment of complex retinal detachment, severe diabetic retinopathy, extraction of nonmagnetic foreign bodies in the ball, standard trabecular resection, combined trabecular resection and the like.
