Intense UV radiation increases the risk of cataracts

Protect the skin against ultraviolet radiation with sunscreen - a mandatory daily program for many, especially during the holiday and travel season. However, very few sun worshipers also pay attention to protecting their eyes from intense UV radiation. But if you leave your eyes exposed to the sun's rays unprotected, the risk of developing cataracts, a progressive lens clouding, increases later. Only surgical measures can then restore visual acuity in cataracts.

Fuzzy, matt and veiled perception of the environment - this is how many people describe the symptoms of the onset of cataracts. If left untreated, colors lose clarity as the disease progresses and vision continues to decrease. "The only helpful treatment for patients with cataracts is the operative replacement of the body's own with artificial lenses," says Dr. Kaweh Shayan-Araghi, medical director of the Artemis Eye Clinic Frankfurt and board member of the professional association of ophthalmologists. A minimally invasive micro-cut technique enables a gentle procedure and leads to precise results. A cut of 2.2 millimeters is sufficient to use ultrasound to shred and disinfect diseased lenses. This is followed by the insertion of a folded artificial lens through the same pin-sized opening. Depending on the personal requirements and needs of the patient, there are several lens shapes to choose from. In addition to cataracts, multifocal lenses also fix short-sightedness and long-sightedness. The toric shape of the multifocal lens also treats astigmatism. Mainly performed on an outpatient basis, the procedure nowadays generally does not require a hospital stay and is one of the most common operations. In Germany, doctors now rid some 600,000 patients of cataracts every year.

But if you want to prevent surgery, you should protect your eyes, especially in summer. In order to be safe from the unpleasant consequences of enjoying the sun, it is advisable to wear sunglasses with a built-in UV filter and CE mark. In addition, sunglasses should cover the eyes as completely as possible. “Experts know a variety of causes that favor cataracts. Patients with pre-existing conditions such as diabetes mellitus or dialysis and cortisone patients are at increased risk. Likewise, cigarette smoke and intense UV radiation are considered risk factors that should not be underestimated, ”adds Dr. Schayan-Araghi. Double plus: In addition to cataracts, sunglasses protect the eyes from retinal diseases such as macular degeneration. (pm)
