Cataract Surgery Astigmatism
According to the World Health Organization, Cataract is a major cause of blindness in the world. Cataracts occur when the natural lens fogs in your eyes. After the cataract is formed, the lens becomes increasingly blurry because the cataract interferes with the light entering your retina. You can have cataracts in one eye or both. Cataracts can occur at any age, but in general cataracts are considered part of the aging process.
Cataracts are a natural process. In the Indonesian dictionary, cataract is an eye disease that causes the lens of the eye to become cloudy. With the opacification of the lens inside the eye, cataracts can cause a decrease in vision. The lens of the eye is responsible for focusing the object clearly, if the lens is turbid, then the vision that was obvious becomes blurred and difficult. Cataracts can occur at any age, but with age, the likelihood of cataracts will also increase. When we were young, our lenses were usually like clear glass, allowing us to see it. As they get older they start to become frozen, like bathroom glass. The incidence of cataracts is even higher in those aged over 75 years. However, the good news about cataract treatments is very successful with the latest surgical techniques.
Astigmatism is a refractive error caused by an uneven curve in the cornea or eye lens. Astigmatism can also mean the cornea is more oval than a ball. Cornea is called the window of the eye. Cornea is called the window of the eye. Before reaching the lens of the eye, the light entering the eye must pass through the cornea first. Then, the light entering the eye continues to reach the retina which acts like a film on the camera to capture what we see. Astigmatism is an irregularity in the corneal arch (somewhat like a sway in a bowling ball) and this shake causes the image to be distorted when they reach the retina and make the view blurred. Sharing astigmatism can be corrected with glasses or contact lenses. Cataract patient with astigmatism who does not want to wear glasses to correct vision deficiency, implant Toric lenses can give him the desired freedom. Those who use Aspheric lens implants and choose Toric Aspheric lenses give them the optical clarity they want.
There are two methods to correct astigmatism simultaneously with cataract surgery, namely intraocular toric lens and limbal relaxation incision (LRI). A toric intraocular lens is a modification of a standard intraocular lens (used in almost all cataract surgeries) which has the necessary astigmatism correction built into the lens. The torque IOL functions like a torik contact lens for astigmatism. That is, torric IOLs have different strengths in different lens meridians to improve the number of nearsightedness or farsightedness in different parts of the eye which are characteristic of astigmatism. If you have astigmatism, toric IOL can reduce your need for glasses after cataract surgery. Limbal relaxation incision (LRI) can be performed during surgery to eliminate or reduce astigmatism. In this procedure, one or more bow-shaped incisions are made near the edge of the cornea. LRI usually heals well and can last forever, however, everyone heals differently. LRI has a certain level of variability produced in the short and long-term. If astigmatism is still a problem after cataract surgery, additional surgical procedures can be done to reduce or eliminate it after your eyes are fully recovered from your cataract procedure. The third way to improve astigmatism occurs after cataract surgery and after the eye has time to heal. LASIK or PRK can be done as an off-label method (not FDA-approved use) to reduce or eliminate astigmatism. In LASIK and PRK, the Excimer laser is used to reshape corneal irregularities. CRP can be done faster than LASIK and is usually more uncomfortable for the first few days. LASIK will require more healing time than the date of cataract surgery and is much more uncomfortable. There is usually an additional cost for this method of correction of astigmatism.
