A cataract is a clouding of the eye’s natural lens that develops gradually, usually due to aging, but can also result from injury, diabetes, or prolonged exposure to UV light. Early warning signs include blurred or dim vision, faded colors, glare from lights, difficulty seeing at night, and occasional double vision. When cataracts start to significantly affect daily activities, surgery is typically recommended. The treatment involves removing the cloudy lens and replacing it with a clear artificial lens, known as an intraocular lens (IOL), and the procedure is usually performed by an ophthalmologist on an outpatient basis. When choosing a hospital, it’s important to consider the surgeon’s experience, hospital accreditation, available technology, and patient reviews. In India, cataract surgery costs can range from ₹15,000 to ₹1,20,000 per eye, depending on the type of surgery and lens used, though government schemes may offer subsidized or free surgery for eligible patients. Pre-operative guidance includes a thorough eye exam, medication review, and arranging transportation, while post-operative care focuses on using prescribed eye drops, avoiding strenuous activities, and attending follow-up appointments. Overall, cataract surgery is safe, highly effective, and can dramatically improve quality of life by restoring clear vision.
