Cataract is a progressive condition in which the natural lens of the eye loses its transparency, leading to blurred vision. Normally clear, the lens becomes opaque over time due to structural protein changes. This prevents light from focusing accurately on the retina. Although most commonly age-related, cataract may also develop due to trauma, diabetes, long-term steroid use, genetic predisposition, or certain metabolic disorders.

What Are the Symptoms of Cataract?

Patients typically complain of blurred or hazy vision. Sensitivity to light may increase, and headlights can become disturbing during night driving. Colors may appear faded or dull. Frequent changes in glasses prescription are common. In advanced stages, double vision or significant vision loss may occur.

How is Cataract Diagnosed?

Diagnosis is made through a comprehensive eye examination. Slit-lamp biomicroscopy is used to evaluate lens opacity. Retinal examination and intraocular pressure measurement may also be performed. The process is painless and quick.

How is Cataract Treated?

Surgery is the only effective treatment. In modern phacoemulsification, the cloudy lens is fragmented using ultrasonic energy and removed through a small incision. An artificial intraocular lens is then implanted. The procedure usually takes 10–15 minutes and is performed under topical anesthesia.

What is the Postoperative Process?

Patients are generally discharged the same day. Mild irritation or tearing may occur initially. Regular use of prescribed drops is essential. Vision usually improves within a few days and stabilizes over the following weeks.

Is Cataract Surgery Safe?

Cataract surgery is one of the most commonly performed and successful operations worldwide. With proper patient selection and an experienced surgeon, complication rates are low. Modern technology provides highly satisfactory visual outcomes.
