It is important to go for eye examinations at your nearest eye clinic these days. This is the generation that is always glued to their smartphones and TVs. Since vision is an integral part of the human life, delaying your regular eye checkup can mean dealing with potential un-called for consequences further down the road. This post will list the most common eyesight problems encountered by patients and what are the corrective steps taken to manage them better.
Initially, when a person goes for an eye test and tests are positive for refractive error in the vision, the solution is to wear glasses or contact lenses that can help in correcting your vision. To put this observation in perspective, as many as two-thirds of the human populace wears spectacles for this purpose, the chances increasing after the age of 65. Sometimes surgery can also be an option.
When a person is faced with common vision problems, such as short-sightedness, long-sightedness and astigmatism, the issue can be solved by prescribing the right corrective lenses to the patient. When the issues mutate into a more advanced form of vision issues, such as cataracts, glaucoma (Bono actually wears tinted glasses because of it), retinal detachment and macular degeneration, then the solution requires a more hands-on approach such as surgery or medical treatments.
The good news is that thanks to advances in medicine and technology in these decades, many eye ailments are curable and treatable. Improved quality of life is well within reach for young children to senior citizens. When it comes to treating shortsightedness, an optician will help you determine the correct solution for you. A test that involves the patient to focus on images visually is undertaken. Your retina determines the rest. When your eye is examined the optician can then be in a better position to prescribe you either conventional spectacles or contact lenses.
If patients feel that wearing spectacles or lenses might interfere with their lifestyle, they can also go for surgery that can take care of their short-sightedness. Radial keratotomy is one way of treating it. The process involves the cornea and some tiny incisions made into it so that the center is flattened and images are correctly focused on the retina as a result. The surgical procedure is performed on one eye at one time and it’s known to work successfully.
There is a risk of complications with this procedure too. The cornea can be infected, resulting in the fluctuation of vision. It’s rare. Instead of radial keratotomy, laser treatment is another alternative with no risk of infected cornea. The laser can remove the microscopic tissue that results in short-sightedness. Laser treatment offers results similar to or better than radial keratotomy. The laser beam removes microscopic amounts of tissue from the centre of the cornea. This effectively flattens the cornea so that light rays focus correctly on the retina.
For long-sightedness, sometimes it can resolve itself naturally. When it doesn’t, the matter can be aided with the help of lenses or glasses. Only the people who particularly get eyestrain are the ones for whom the surgery option is the best bet. As for astigmatism, an uneven cornea can be corrected by a lens that can neutralize its effect to corrected-ness.
If the patient is facing the issue of cataracts in their eyes, the hardened natural lens in the eyes can potential obscure vision. Cataracts used to be difficult to treat in the old days. It required a week’s stay in the hospital and a procedure that involved the administration of anesthetic to patients. Thanks to the discovery of a process named lens phacoemulsification, tiny lens fragments in the cataract can be removed via ultrasound with some incisions. These incisions rarely require any stitches. An artificial lens is then inserted so that the vision is perfect. The whole procedure lasts 1 to 2 hours only.
