Abstract
This article is a document which gives a brief information about the cataract operation and it is also an informative guide for people who will undergo cataract surgery (Harvard Medical School, Harvard Health Publishing, 2020; 2024; 2022). Cataracts occur when proteins in the lens of your eye clump together and make it difficult for light to pass through clearly. When the clumps are small, you may not notice the changes very much because they are subtle. Objects may lose sharpness, vision may blur slightly, and distant objects may start to appear blurrier, while near vision temporarily improves in a phenomenon called myopic shift. Light rays pass through the cornea to the lens, which focuses images on the retina—a layer of light-sensitive tissue at the back of the eye. Light rays first pass through the vitreous humor, a clear, gel-like substance that fills most of the eye. The retina captures images, which are then sent to the brain via the optic nerve.Usually, cataracts develop gradually in both eyes. However, some people lose more vision in one eye than the other. As the cataract thickens, your vision becomes blurrier. You may have difficulty seeing when driving at night or reading small print and other details. Over time, however, cataracts can cause colors to fade, making driving at night difficult and making everyday tasks like reading or recognizing faces increasingly difficult. A yellowish haze can color everything you see and contribute to loss of detailed vision. At first, updating your eyeglass prescription may give you clear enough vision. Eventually, however, the blur will worsen and impair your vision to the point where you will need cataract surgery to drive or do most other activities of daily living. Cataracts are a very common eye condition, especially as we age. Cataracts are more than just a condition that causes blurry vision and makes it difficult to distinguish colors. Untreated cataracts can limit vision to the point of blindness. The only definitive treatment for cataracts is surgery. The procedure has an outstanding track record of safety and success.
