Problems solved by technology

[0002] At present, eye preparations generally include drops for daily use and drops for surgery, and drops for surgery are more researched on drops during surgery, and less research is done on drops before surgery. At the same time, existing pre-operative drops For eye cleaning, normal saline is generally used to clean the cornea, but the use of normal saline to rinse the eyes has a high osmotic pressure, which is irritating to the eye and cannot effectively disinfect the cornea, which in turn leads to eye damage. Insufficient cleansing of the eye area makes it easy to cause secondary infection of the eye or recurrence of eye diseases during or after the follow-up operation

preparation example Construction

[0020] The present invention also provides a kind of preparation method of preoperative corneal washing solution, comprising the following steps:

[0021] The mydriatic agent, the analgesic, the bactericide and the pH regulator are mixed, the pH is adjusted to 6-7.5, and then mixed with the electrolyte balance regulator to obtain a mixture.

[0022] The mixture and activated carbon are mixed according to the mass ratio of 1:0.01-0.03. Activated carbon can remove certain pigments or impurities in the preoperative corneal irrigation fluid, reduce the content of germs or other impurities in the preoperative corneal irrigation fluid, and make it more comfortable to use.

[0023] The mixture was mixed with activated carbon and filtered. Filtration is to pass through activated carbon filter, 0.44μm filter membrane, and 0.22μm filter membrane in order to remove impurities or bacteria with large particle size in activated carbon and preoperative corneal irrigation fluid.

Abstract

The invention relates to the field of eye-drop preparations and particularly relates to a pre-operation cornea flushing fluid and a preparation method and application of the pre-operation cornea flushing fluid. The pre-operation cornea flushing fluid is mainly prepared from various raw materials by weight: 0.5-1 part of an electrolyte balance regulator, 0.3-0.7 part of a pH regulator, 0.1-0.4 partof a bactericide, 0.06-0.12 part of a mydriatic, and 0.01-0.03 part of a pain killer. The pre-operation cornea flushing fluid can flush the cornea well before the operation, the particulate matter possibly adhered to the surface of the cornea is cleared, a therapist captures the diseased region conveniently, meanwhile, the cornea is sterilized, the pupillary is dilated, the pain is alleviated, the operation effect of the eye operation is improved, the secondary postoperative infection is prevented, and the osmotic pressure and the pH of the flushing fluid are appropriate, so that the irritation of the flushing fluid on the eye is reduced.
