Vision loss of any degree can be frightening and frustrating. It can have a significant impact on the quality of life. Cataracts are the most common source of vision loss usually comes with age. Fortunately, there are ways to improve the visual imparities that come with cataracts by using implantable lenses, such as AcrySof Toric lenses.
Your eyes have two natural lenses that are responsible for focusing light to your retina. The outer focusing lens is called the cornea; the inner lens is called the crystalline lens. When light enters the eye, it first passes through the cornea, then through the crystalline lens. As it passes through these two lenses, the rays of light are bent so that they meet at a single point on the retina. The retina then sends the electrical pulses to the brain where they are interpreted as a picture. The crystalline lens is made up mostly of water and protein. As you age, sometimes those proteins clump together, causing the lens to become discolored and blurry. When this happens, it is known as cataract. In order to restore visual acuity, it is necessary to replace the natural crystalline lens with an intraocular lens implant.
Unfortunately, many people that suffer from cataracts also suffer from astigmatism. Astigmatism occurs when there is an irregularity in the shape of the eye’s refractive surface that can distort vision. While there are a variety of implantable lenses available, AcrySof Toric lenses have the advantage of being able to correct cataracts and treat astigmatism. This can result in less need for the use of glasses or contact lenses for distance after they are implanted.
