People above 65 years of age are usually affected by cataract disease. It starts with huge flow of water from the eyes and then later hampers the proper functioning of retina. As the retina gets damaged, the person cannot see things properly as his eyes fail to focus light. Since retina is nothing but a tissue which converts light signals to electrical impulses and transports them back to brain. And once it gets damaged, people even fail to recognize things. Well working retina is transparent, but the eye suffering from cataract will have a yellowish retina and distracts the intensity of the light falling on the eye, impacting the vision.

Although cataract surgery is one of safest surgeries of the modern day, there are some kinds of risks involved. About 98% of cataract surgeries are successful but I am talking about that 2%. You never know, even you can fall in that nullified category. So, before you opt for cataract surgery, it is very important to understand the risk factors involved in it.

There is a high probability of eye getting infected which is also termed as Endophthalmitis. The mechanism involved in surgery is such that it can leave your whole eye infected. And to prevent this, surgeons pour few drops of antibiotic liquid on the eyes before they get operated. This drug nullifies the chance of getting infected to a great extent but still 1 out of every 3000 patients do suffer from this infection.

Well this conclusion is very rare but still there is a possibility that it might happen. During the surgery, the macula (which is the central part of the retina) may get inflamed and might result in burning the vision. As macula starts swelling during the surgery, so there is great chance of its getting inflamed but it is injected with some steroids, which kills such danger. There is one more deadly risk of cataract surgery. There is possibility that the retina might get detached with the eyes, this is also called as retinal detachment. The detachment of retina from the back of eye can damage the vision of that eye for a lifetime. But this occurs to about half of the once percent of all cataract surgeries.

The most frightful and deadly risk is that the cataract surgery might even lead to choroidal hemorrhage. Choroids are actually the blood vessels which carry blood to the retina. This obviously means that they are a vital part of the eye. But during cataract surgery, there is a possibility that these choroids start bleeding. And this is common to the patients who have high blood pressure. So, if the surgeons are successful in stopping the process quickly, then it might not harm the vision of that person. But, if he fails to do so, then the patient might loose his vision forever.

These were few of the risks that are involved in the cataract surgeries, which you should be aware of. But the technology involved in these surgeries is so sophisticated that the probability of these hazards is almost nullified. So, people can opt for cataract surgeries if they are suffering from eye cataract.
