Cataracts usually develop very slowly. These cloudy areas of the eye’s lens cause blurry vision, double vision, and sensitivity to light. When your symptoms start to interfere with your daily life, it’s time to visit a cataract surgeon near Chicago. During your cataract procedure, the cloudy lens will be removed and replaced with an intraocular lens (IOL). This lens is a flexible, synthetic lens that functions just like a natural, healthy lens would. It receives light and focuses it on the retina at the back of the eye. This allows your brain to receive images via the optic nerve.
Your cataract surgeon can walk you through the types of IOLs available to you. He or she might suggest an aspheric IOL, which mimics the natural variations in the curve of the eye’s lens. This could help you enjoy sharper vision. On the other hand, your ophthalmologist may recommend a toric IOL if you have nearsightedness, farsightedness, or astigmatism. This lets you see things clearly, without the blurriness that astigmatism causes.
