Eye knowledge
What is cataract?
All kinds of reasons such as aging, genetics, local nutritional disorders, immune and metabolic abnormalities, trauma, poisoning, radiation, etc., can cause lens metabolism disorders, leading to lens protein degeneration and opacity, which is called cataract.
What is an intraocular lens?
The main components of human crystals are protein and water, which will become fogged or turbid due to aging, and fogged crystals will prevent light and images from being projected on the retina.
What is glaucoma?
Glaucoma is a group of diseases characterized by atrophy and depression of the optic nipple, visual field defect, and decreased vision.
Clinical manifestations and treatment of cataract
Unilateral or bilateral, the onset of the two eyes may occur sequentially, and the visual acuity may be progressively reduced. Due to the opacity of the lens cortex, different parts of the lens may have different refractive powers, which may cause glare, or single eye diplopia, and increased myopia. Clinically, senile cataracts are classified There are three types: cortical, nuclear and subcapsular.
