About Cataracts and Its Causes
As humans age, the eyes deteriorate naturally thus leading to eye complications. One of these complications is called a cataract. If this cataract is untreated, it will lead to severe visual impairment and even blindness. The cataracts form inside the lens that is located behind the iris. The function of the lens is to focus light that passes through the eye producing the retinal images. As a human being grow older, these eye lenses flexibility reduces and the protein inside forms a clump clouding the lens. When a cataract develops, the clouding enlarges and thickens which causes blockage of light that enters the lens. This prevents the images from reaching the retina thus blurring your vision. Cataracts develop unevenly in both eyes. The unevenness may probably be because the other eye is more affected by the cataract than the other one.
If you want to restore your vision, cataract surgery is highly recommended because it is an effective and proven method. Cataract surgery can be quite expensive and as other surgery goes, there are risks because some patients may have an allergic reaction to anesthesia. There are also patients that can have complications during the surgery but this type of surgery has a high success rate and is highly recommended. It is also one of the safest and most effective types of surgery. About 90 percent of cases have a better vision afterwards. The need for other things after surgery might be possible such as wearing eyeglasses. This is because the vision cannot be fully repaired like 20/20 vision.
If you take the option to improve distance vision after having a monofocal lens surgery, you will still need to use glasses when reading. You will also have to wear eyeglasses after for distance if you wish to improve your short-sightedness. Usually, after surgery, you will feel itching and mild discomfort and some fluid discharge are also common. Your eye will be sensitive to touch and light but after one or two days, this moderate discomfort should disappear. You will have to use eyedrops to help the healing and decrease the risk of infection.
Most of the time, there will be a need for a pair of reading eyeglasses after unless you choose presbyopia-correcting IOLs. At times, you might need progressive lenses in order to deal with the mild residual refractive errors and presbyopia. For your comfort, there are glasses that are prescribed after the cataract surgery.
