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.
Are you going to undergo surgery but afraid of your vision after cataract surgery? This can be very daunting for anyone who wants nothing but a successful surgery to go through. You don’t have to worry a lot about most patients that undergo the surgery end up having good and healthy eyes. Their vision improves and they can even pass the DMV vision test even without the aid of eyeglasses.
As a patient, you also need to consider that there is important when it comes to waiting for more time so that your eyes can adjust fully to the cataract surgery. It is normal to feel discomfort in your eyes and your body are recovering, but this is not something that you will be feeling for a long time.
Symptoms That You Could Encounter After Surgery
It is n question that you will have better vision after cataract surgery and in certain circumstances, there can be some things that you will have to deal with after. One of those would be trouble in seeing cars or even traffic lights at night. Sometimes you might also have trouble seeing spots on your clothes, on the dishes, and on the counters. Some people have problems in recognizing facial gestures while there are people who need additional light so that they can read.
Other symptoms include feeling tired after or while watching TV. It is normal to have difficulty in seeing when it is after the surgery and this is because of the reduction in contrast sensitivity.
These symptoms are very common and the difficulty that people experience is also connected with the need to the brain to be able to adjust with the new vision and the lenses that you now have. It is called neuro-adaptation and that is what you call the adjustment process where the eyes are slowly altering in order to cope with the surgery.
Patients with multifocal IOL will commonly experience the reduction in contrast sensitivity and this is because they have been designed along with several focal points in order to accommodate the various distances that the eyes can see. The structure then challenges the various types of neurons that are present in the visual cortex. These neurons are responsible for the processing of the area as well as the distances in vision and can result in increased neural noise level as well as reduced detection point; thus the low contrast sensitivity.
It is important that you are aware of the before and after guidelines for your cataract surgery so that you are prepared for the outcome. In the long run, your vision will eventually improve which is why you don’t have to worry about the symptoms that you are experiencing now as it is only the natural reaction of the body to changes.
