Cataract (मोतियाबिंद)

Overview

A cataract is a common eye condition where the normally clear lens of the eye becomes cloudy, leading to blurred vision, difficulty with glare, and eventually vision loss if left untreated. Cataracts typically develop with age but can also result from genetics, medical conditions (like diabetes), long-term sun exposure, or eye injuries. While cataracts can affect one or both eyes, they don’t spread from one eye to the other. The good news is that cataracts are highly treatable, and modern surgical techniques can restore vision effectively.

Routinely performed procedures

    1. Phacoemulsification (Phaco Surgery): The most common procedure, where a small incision allows an ultrasound device to break up the cloudy lens. The pieces are removed, and an artificial lens (IOL) is implanted. This quick procedure has a short recovery time.

    2. Extracapsular Cataract Extraction (ECCE): For advanced cataracts, ECCE requires a larger incision to remove the lens in one piece, then inserts an IOL. Recovery is longer, but it’s effective for dense cataracts.

    3. Femtosecond Laser-Assisted Surgery: This advanced laser technique makes precise incisions and softens the cataract for removal, yielding excellent outcomes.

    4. Posterior Capsule Opacification (PCO) Treatment: A YAG laser capsulotomy treats post-surgery cloudiness, restoring vision quickly and painlessly.

Frequently Asked Questions!

Cataracts primarily develop due to aging, as the proteins in the eye lens start to break down and clump together. Other causes include prolonged exposure to UV radiation, certain medical conditions like diabetes, smoking, eye injuries, and prolonged use of steroid medications.

 

Common symptoms of cataracts include blurry vision, faded colors, increased sensitivity to glare, trouble seeing at night, and seeing “halos” around lights. An eye exam by an ophthalmologist is essential for diagnosing cataracts accurately.

 

You should consider surgery when cataracts start interfering with your daily activities, like reading, driving, or recognizing faces. If you’re experiencing persistent vision problems that affect your quality of life, surgery can be a good option.

 

Cataract surgery is one of the safest and most commonly performed procedures, with a high success rate. However, like any surgery, it has potential risks, including infection, bleeding, inflammation, retinal detachment, and vision changes. Discuss any concerns with your doctor to understand your specific risk factors.

 

Most patients experience significant vision improvement within a few days after surgery, but complete healing can take up to 6 weeks. During this time, it’s essential to avoid strenuous activities, protect your eye from dust, and use prescribed eye drops to prevent infection and promote healing.
