Cataract

A cataract is a clouding of the natural lens of the eye that causes a reduction in visual acuity.

• congenital cataract;
• age-related cataract;
• traumatic cataract;
• complicated cataract.

The principal symptom is reduced visual acuity. In addition to poorer vision, a person may experience double vision, changes in colour perception and glare.

Cataract treatment

A cataract is treated surgically with phacoemulsification and implantation of an artificial intraocular lens.

Surgery is indicated when the cataract causes visual difficulties. When a cataract is in an earlier stage, surgery may be more straightforward and recovery of visual function may be quicker.

Cataract surgery is one of the most frequently performed operations in medicine. It is carried out using a modern ultrasound method without an overnight hospital stay. The clouded natural lens is removed and replaced with an artificial lens. Visual function then recovers during the postoperative period according to the condition of the eye and the healing process.
