A cataract is known to be changed in the lens of the eye. This would make the lens of the eye become more cloudy so the light will not have the ability to enter the eye properly. There are some people who undergo surgery in order to cure this condition.
Glaucoma is known to be the condition wherein there is a buildup in the pressure of the eye. When there is too much pressure, some issues may arise because they may cause some damage to the optic nerve. The optic nerve is in charge of sending signals to the brain so that the brain can start processing the information that it gets.
Before diving into the reason why smoking harms people’s lens, it is important to note that too much of smoking can result in a lot of diseases in the body. A cataract simply means a disease of the eye, causing its opacity or the clouding of the eye’s lens. Cataract can lead to blindness unless necessary treatments are done on it. Different researches have shown that smoking has the tendency of affecting the area of the retina known as Macula. When this is affected, it leads to what is known as Macular Degeneration.
This will, in turn, reduce the sharpness of the eyes, activities like reading, driving will no longer be effectively carried out. Smoking increases your risk of having a cataract. While you might naturally develop this eyes defect, smoking will double your chance of having a cataract. Smoking can also cause the inflammation of the uvea, which is the eye’s middle layer, and this can increase your chance of developing a cataract.
Cataracts are the clouding of the natural lens of the human eye, which obstructs the provision of enough light for sight or vision. There are three different major types of cataracts, which are cortical cataracts, sclerotic nuclear cataracts, and posterior subcapsular cataracts. Cataracts do not really respect any age, but it occurs more as one gets older; that is, it increases with respect to age. It occurs well in the middle ages of about 40 to 50 years of age, but it gets worsened at age 60 upward.
Why does this happen? It simply happens due to the fact that the proteins of the eye lens decrease or degrade as time goes on. Hypertension and diabetes mellitus, which is also common among the old aged people can also aid the lens proteins degrading process. Some environmental factors such as ultraviolet light, toxins, and radiations accumulate over time, thereby improving cataracts in the eyes. This also alters the chemical processes and gene expressions within the eyes.
The eyes are very useful parts of the body responsible for sight or seeing. This organ is very delicate and should be well taken care of, and protected as much as possible. Nevertheless, there are several diseases or ailment that affect this organ. The worst case scenario that can happen to the eyes is complete blindness. As different ailments can have different effects on the eyes, complete blindness is not the only negative or resulting effect of eyes diseases. There can be partial blindness or poor sight sometimes.
A good example of a partial loss of vision is cataract. Cataract is a kind of partial loss of vision due to the clouding of the eye lens. This causes about fifty percent of the world's blindness scenario today. Cataract itself is not or does not cause complete blindness, but when it refused to be taken care of, it can lead to total loss of sight. In order to cure cataract kind of blindness, cataract surgery is simply done and implantation of intraocular lens.
The organ responsible for our sight is a real delicate one that should be well taken care of. Though this component looks small among all the components making up the body, when negatively affected, it can bring severe pain to the body. There are major problems that can affect the eyes, which include shortsightedness, long-sightedness, and color blindness, as popularly known, but they are not limited just to these three. Another defect of the eyes is referred to as a cataract.
This is simply the gradual loss of sight or poor vision due to the clouding of the eye lens. Talking about how the eye lens can be clouded, we have to check the causes of cataract. These causes include aging, radiation exposure, trauma, and aftermath of eye surgery sometimes. The lens is being clouded due to the accumulation of yellowish-brown pigment or clumps of protein, which reduces the transmission of light to the retina behind the eyes. Thus, cataract is formed.
Knowing what cataracts mean, their symptoms, and risks, the cure or treatment to cataracts should not be left behind. How are cataracts cured? The main cure for cataracts is through surgery. Still, there are several methods of surgery that can be used, such as phacoemulsification, extracapsular cataract extraction, and intracapsular cataract extraction. Meanwhile, phacoemulsification is the cataract surgery which is most widely used in the developed parts of the world.
Phacoemulsification is simply a cataract surgery process whereby the natural lens of the patient is been dissolved into liquid by ultrasonic vibration and then drained out of the eyes. Then the intraocular lens (IOL) is used to replace the natural lens. You might be thinking the surgery will be painful, but when the doctors might have put some necessary parameters into consideration, the surgery causes very little or no pain. It is usually a safe and successful surgery, and it can even help in curing some other eye infections.
There are several causes of cataract in the eyes. These causes include smoking and intake of alcohol, old age, trauma, radiation, genetics, inadequate vitamin C, medications, post-operative, and even skin diseases, plus some other diseases which can be metabolic and nutritional, congenital, and genetic syndromes. Skin is also an organ in the body, the largest organ actually; and some infections on this skin can have effect on the eyes, causing cataracts especially.
But how, which skin diseases can cause cataracts? The eye lens and the skin possess the same embryological origin, and they can be affected by some similar diseases. Some people develop shield ulcer cataracts occasionally due to eczema and atopic dermatitis infections on the skin. An autosomal recessive disorder is the ichthyosis skin disease which is associated with nuclear sclerosis and cuneiform cataracts. Another skin disorders that are associated with nuclear sclerosis and cuneiform cataracts are pemphigus and basal-cell nevus.
Cataract, a form of low vision quality due to the clouding of the eye lens, is rampant throughout the whole world. It can occur in anybody and at any place, irrespective. It only needs to be avoided by taking some necessary precautions like; avoiding smoking, and probably using sunglasses; but in some worse scenario like someone that was born with it, such a person will have to go for the treatment, which is best done as a surgery. Cataracts are the cause of about fifty percent of the blindness that occurs in the world.
This implies that the ailment affects relatively all nations without leaving the United States behind. About twenty million people in the world are affected by cataracts. About sixty percent of blindness in South America and Africa are as a result of cataracts; while even about five percent blindness in the United States is caused by cataracts. By the advanced age of about 75 upward, over fifty percent are affected with cataracts in the United States.
Cataracts can occur in people's eyes as a result of some environmental factors, and also as well as natural occurrence. When the symptoms of this infection has been suspected, some things can be put into places, such as using new eyeglasses, anti-glare sunglasses, brighter lighting, or magnifying lenses. When these above listed measures do not correct the eye defect, then the best way to cure it in this present day world is through cataract surgery. This surgery is carried out in such a way the natural lens that has been clouded would be removed and replaced by a new artificial lens.
The surgery should be carefully done and the necessary measures before and after the surgery should be taken to. However, there are some ways being claimed through which cataracts can be cured. One of these is the application of eye drops containing lanosterol. Other professed means by people is the use of local herbs in various countries, especially the developing ones. A good example is vision vital capsules in the western part of Africa.
A cataract is a worldwide eye defect, and it can surely be cured. But during the infection and this curing process, there are some precautions to be taken. Any eyes surgeon that does not take to these precautions is questionable, the eye surgery for the cataracts treatment can cause trouble and the cataract leading to probably something worse. One of the major precautions to be taken is to avoid taking some medications; this is simply because some medications worsen the effect of cataracts in the eyes; they increase the risk of suffering from cataract. The first medication to prevent totally is corticosteroids medication.
This should be avoided as the medication is known to cause cataracts. Some other medications also have their effects; they should most likely be avoided during cataract surgery. These medications include aspirin and its products, coumadin, Celebrex, Naprosyn, Plavix, and ibuprofen. Some herbs also need to be avoided, such as gingko, feverfew, fish oil, chondroitin, and a few others.
