Method for cleaning intraocular lens

Abstract

According to the cleaning method for the intraocular lens, the cleaning medium is set to be at the specific temperature, so that the intraocular lens is in a hardened state during cleaning and is not prone to deformation during cleaning, the surface viscosity of the intraocular lens in the hardened state is reduced, the adhesion to impurities and chippings is weakened, cleaning is more facilitated, and the cleaning efficiency is improved. And the cleanliness of the cleaned intraocular lens is improved, so that postoperative complications such as inflammation caused by impurities and debris on the surface of the uncleaned intraocular lens implanted into eyes are avoided. The cleaning method of the intraocular lens comprises the following steps: a preparation step: providing a cleaning tank with an upper opening to contain a liquid cleaning medium, and fixedly arranging the intraocular lens 1 in the cleaning tank to be soaked in the cleaning medium; and a cleaning step in which ultrasonic vibration is applied to the cleaning tank to clean the intraocular lens, and in the cleaning step, the cleaning medium is maintained at a specific temperature so that the intraocular lens is in a hardened state.

Description

How to clean intraocular lens technical field The present invention mainly relates to artificial lens field, be specifically related to a kind of cleaning method of artificial lens. Background technique An intraocular lens is an artificial lens that can be implanted in the eye to replace people who have become cloudy due to cataract disease The natural crystal in the eye, or used in refractive surgery to correct vision in the human eye. Intraocular lenses are made of transparent polymer materials made. These polymer materials can be hard or soft. Intraocular lenses made of hard materials that must pass A larger incision (usually larger than 6 mm) can be implanted into the eye, and a larger incision means various complications after surgery. The greater the possibility of morbidity, so it has basically been eliminated in developed countries. Intraocular lenses made of soft materials are also often Known as foldable intraocular lenses, they can be folded or rolle...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a cleaning method for intraocular lens, which can solve the problem that in the prior art, the intraocular lens is often easily dropped and deformed when cleaning after processing, and the surface of soft materials is highly viscous, which makes the surface easy to absorb fine particles. Particles lead to poor cleanliness of the surface of the intraocular lens after cleaning, which can easily cause complications such as posterior capsule opacity (PCO) if it enters the eye
