The cataract treatment mostly consists in the surgical procedure. The natural lens of the eye is removed and replaced with a new one (artificial lens). In most surgical procedures intraocular lens is used. The intraocular lens is made from silicone, plastic or acrylic. But there are some exceptions in which some patients can not tolerate the intraocular lens, and then the surgery consists in replacing of the natural lens with regular contact lenses or glasses.
Subcapsular cataract
The opacity under the posterior capsule of the lens affects disproportionately the vision because the opacity is located in the intersection point of the rays of light from the seen object. These cataracts are particularly annoying in case of bright light as described on Did You Know Homes blog.
Cataract removal – Cataract operation
Cataract removal is a procedure through which a clouded lens is removed. The cataract is removed so that the vision improves. The operation consists in the fact that the natural lens is replaced with an artificial one. Cataract removal is usually recommended to patients who can’t see good because of this disease. There are two possibilities to remove the cataract: the first is with surgical instruments and aspiration, and the second with an ultrasonic energy for breaking and removing the lens.
Cataract stages – cataract lenses
As the cataract grows, the patient symptoms are getting worse. The progression of the cataract will make you understand that you need treatment. Intraocular lenses are of two types: monofocal or multifocal intraocular lenses. Multifocal intraocular lenses correct the sight near and at distance.
