A variety of eye pathologies can lead to the development of cataract, a condition in which the lens of the eye becomes cloudy, making it difficult for light rays to be clearly projected onto the retina. As a result, the patient sees a blurry, foggy image with muffled colours, causing difficulties with moving, reading, and driving, especially at dusk and at night.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/section>

Zonular weakness<\/h2><\/div><\/div>

The weakening of the lens\u2019s zonular apparatus is associated mostly with pseudoexfoliation syndrome, glaucoma, myopia, some forms of retinal dystrophy, traumatic eye injury, or intraocular surgery. When the cataract is hypermature, the lens becomes completely cloudy (white or milky cataract). In all these cases, the lens zonules which support the lens and keep it in the correct position undergo degradation. Subsequently, “wobbling” or subluxation of the lens may develop. In these patients, during cataract procedures, capsular tension rings made of polymer, usually PMMA (polymethylmethacrylate), are used.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/section>
