Description

technical field [0001] The invention relates to the technical field of eye drops, in particular to a lanosterol eye drop and a preparation method thereof. Background technique [0002] All kinds of reasons, such as aging, heredity, local nutritional disorders, immune and metabolic abnormalities, trauma, poisoning, radiation, etc., can cause lens metabolic disorders, resulting in lens protein denaturation and turbidity, which is called cataract. Obstruction cannot be projected on the retina, resulting in blurred vision. It is more common in people over 40 years old, and the incidence rate increases with age. [0003] At present, there is no clinical drug that can effectively treat cataracts, and affected individuals can only improve vision through surgery to replace intraocular lenses. Recent literature has demonstrated that steroid molecules can reduce the severity of cataracts in the eyes of animals (Quinlan 2015). Among them, lanosterol (Lanosterol) has been proven to r...
