What Is a Cataract?
A cataract is clouding of the eye's natural lens. It commonly develops with age, but trauma, medication, metabolic disease and other factors may also contribute. It can cause blurred vision, glare, reduced contrast and changes in colour perception.
Diagnosis and Timing
Diagnosis is made with a comprehensive eye examination. Surgery is considered when the cataract meaningfully affects daily activities or prevents assessment or treatment of other eye disease.
Cataract Surgery
In modern phacoemulsification surgery, the cloudy lens is removed through a small incision and replaced with an intraocular lens. Anaesthesia, surgical planning and postoperative medication are individualized.
Intraocular Lens Options
Monofocal, toric and multifocal or trifocal lenses have different optical goals and trade-offs. The choice depends on corneal measurements, retinal and optic-nerve health, lifestyle and expectations.
Recovery and Follow-up
Vision often improves progressively after surgery. Prescribed drops, eye protection and scheduled controls support safe healing. Sudden pain, marked redness or an abrupt decrease in vision requires prompt assessment.
