What is Cataract Surgery?
Cataract surgery is a procedure to remove the cloudy lens of the eye, which develops as a result of cataracts, and replace it with an artificial lens. Cataracts cause blurry vision and can affect daily activities. The surgery restores clear vision and is typically performed on an outpatient basis.
Indications for Cataract Surgery
Cataract surgery is performed to treat cataracts that impair vision and make tasks like reading, driving, or recognizing faces difficult. It’s recommended when cataracts significantly interfere with daily life or other eye conditions, such as glaucoma, are present. Without surgery, cataracts can lead to vision loss.
Preparation for Cataract Surgery
Before cataract surgery, the ophthalmologist will conduct a thorough eye examination to measure the size and shape of the eye, allowing for the selection of an appropriate artificial lens. Patients may be asked to avoid certain medications and use prescribed eye drops to reduce the risk of infection.
Cataract Surgery Procedure
During the procedure, the surgeon makes a small incision in the eye to remove the cloudy lens. This is often done using ultrasound to break up the lens before removing it. The artificial intraocular lens (IOL) is then inserted in its place. The surgery typically takes about 30 minutes, and patients remain awake but comfortable.
Recovery after Cataract Surgery
Recovery is generally quick, with most people experiencing improved vision within a few days. Patients may need to use eye drops and avoid strenuous activity for a few weeks. Follow-up visits will monitor the healing process.
Risks of Cataract Surgery
Though cataract surgery is generally safe, there are some risks, including infection, bleeding, swelling, or retinal detachment. Rare complications may require further treatment.
Benefits of Cataract Surgery
Cataract surgery significantly improves vision, allowing patients to return to normal activities with enhanced clarity. It can greatly improve the quality of life by restoring vision, reducing glare, and improving color perception.
