Cataracts are a plague to eyesight and vision. A cataract is a cloudiness in the lens of the eye that causes a decrease in vision. Since the eye lens is clear, it allows light to enter and focus on whatever the person is seeing. When a cataract develops, this lens becomes cloudy and cuts off the light entering the eye, making it difficult to see and focus.
Cataracts are a leading factor in half the cases of blindness, most commonly seen in older adults. If left untreated, they can grow into a serious problem. At this point in time, surgically removing cataracts is still the only known cure in the field of medicine, especially when the cataract is at an advanced state. The three best types of surgeries to remove cataracts are Phacoemulsification, Extracapsular cataract surgery, and Intracapsular cataract surgery.
To give a brief overview of what each type of surgery covers;
Phacoemulsification cataract surgery– A procedure that takes less than an hour to perform, the cataract is removed to restore the lens of the eye to its prior clear cloud-free state. It is a commonly sought after procedure.
Extracapsular cataract surgery – A procedure deployed in the cases of advanced cataracts. The lens of the eye is removed while the elastic capsule covering the lens is left mostly intact in order to artificially fit in an intraocular lens (IOL). The recovery period of time post-surgery is longer in order to allow the stitches to heal.
Intracapsular cataract surgery – Even more, advanced than extracapsular cataract surgery, this procedure completely removes the eye lens as well as the surrounding elastic capsule, leaving the eye without a lens (aphakic). The vision is corrected by placing extremely thick eyeglasses or by wearing contact lenses. This method is used rarely or in extreme cases as it is useful in the event of trauma to the eye.
Prior to surgery, a patient undergoes a complete and thorough eye exam, along with eye tests, in order to ensure that they are suitable and not at risk for the surgery. After briefing on the best type of intraocular lens suited to the patient, the doctor may prescribe eye drops to be used before the surgery.
Once the surgery is completed, the patient might be instructed to wear an eye-patch until the next exam, and give eye drops to help with the healing as well as prevent the risk of infection. During the recovery and after, it is advisable to wear dark sunglasses when outside after removing the eye-patch. Remember to wash hands thoroughly before touching the eye. Most importantly, it is best not to strain the eye with any strenuous activities.
