Astigmatism Correction
Cataract surgery is a procedure designed to remove the clouded lens of the eye, which typically affects vision, and often involves replacing it with an artificial lens. Cataracts occur when the normally clear lens becomes opaque, leading to visual impairment. The surgery is usually performed on an outpatient basis and takes approximately 30 minutes. During the procedure, the surgeon makes a small incision in the cornea, extracts the cloudy lens, and inserts an artificial lens into the eye. Most patients experience significant improvements in their vision and can return to normal activities within a few days. Cataract surgery is considered safe, with a high success rate, and most patients report enhanced vision and an improved quality of life following the procedure.
About Cataract Surgery
Cataract surgery is a widely performed and safe procedure in India, carried out by skilled ophthalmologists. This operation involves removing the cloudy lens of the eye and replacing it with an artificial lens to enhance vision. In India, cataracts are prevalent, largely due to high levels of sunlight exposure, and the procedure is readily accessible at numerous hospitals and clinics across the country.
The lens of the eye is responsible for refracting light rays to help you see clearly. When a cataract forms, the lens becomes cloudy, akin to viewing through a foggy or dusty car windshield. This can result in blurred, hazy, or less vibrant colors.
Procedure of Cataract Surgery
Cataract surgery typically entails the removal of the cloudy lens and its replacement with a clear artificial lens, known as an intraocular lens (IOL). The surgery is usually performed on an outpatient basis and generally takes less than an hour. Below are the key steps involved in the procedure:
-
Anesthesia: The procedure begins with the administration of anesthesia, which may be local or general, based on the patient’s preference and the surgeon’s recommendation.
-
Incision: The surgeon makes a small incision in the cornea to access the cloudy lens.
-
Lens Removal: Using ultrasound or laser energy, the surgeon breaks up and removes the cloudy lens while keeping the lens capsule intact.
-
IOL Implantation: The IOL is then inserted through the incision and carefully placed into the lens capsule, effectively replacing the natural lens to restore clear vision.
-
Closure: After positioning the IOL, the surgeon will close the incision using tiny stitches or may use self-sealing incisions.
-
Recovery: Post-surgery, patients might experience mild discomfort, light sensitivity, and blurred vision. It is essential to use prescribed eye drops and avoid rubbing the eyes for several weeks. Additionally, patients should refrain from strenuous activities and heavy lifting for a few days.
Choosing a qualified and experienced surgeon with a proven track record of successful cataract surgeries is crucial for ensuring a safe and effective procedure. Overall, cataract surgery is a common and generally safe operation that can significantly improve vision and enhance the quality of life for many individuals.
