Definitions
- the present invention relates to a perfusion solution for eye surgery for use in cataract surgery, intraocular lens implantation surgery, or glaucoma surgery. More particularly, the present invention relates to a perfusion solution for ophthalmic surgery suitable for protecting intraocular tissues, aspirating and removing surgical residues in the eye, and preventing corneal epithelium and conjunctiva from drying, in order to perform the surgery safely and effectively. .
- Conventional technology Conventional technology
- the perfusate used as a surgical aid plays an important role.
- the aqueous humor flows out of the anterior chamber by incising the periphery of the cornea with a scalpel at the start of the operation.

- Osmotic pressure and pH are physiologically harmonized with ocular tissues and endothelial cells.
- D-3-hydroxybutyric acid or a salt thereof used as an active ingredient in the present invention is known as a biological component of humans and most other mammals, is biosynthesized in the process of fatty acid formation in the liver, and is produced by blood. It is transported to the cornea and other extrahepatic peripheral tissues and is used as an efficient energy source (see Leninja Ishinsei Kagaku, 2nd ed., P. 625, 1993 and NATURE, No. 4841, p. 597). , 1962).
