What to expect before and after cataract surgery

Cataract surgery is a common and highly effective procedure designed to restore vision by removing the eye’s cloudy natural lens and replacing it with a clear artificial intraocular lens (IOL). Before the surgery, patients undergo a thorough eye examination to determine the severity of the cataract and choose the appropriate type of IOL based on their vision needs and lifestyle.

On the day of the surgery, patients receive local anaesthesia to numb the eye. The procedure itself is usually quick, often completed in less than 30 minutes. Most people remain awake but comfortable throughout. It is an outpatient surgery, meaning patients can go home the same day. After the surgery, vision might be blurry initially as the eye begins to heal and adjust to the new lens.

Improvement typically occurs within a few days. Patients are advised to use prescribed eye drops for several weeks and to wear an eye shield, particularly at night, to protect the healing eye.

During recovery, activities such as heavy lifting, bending over, and rubbing the eye should be avoided. Most people return to their normal routine within a few days, although full healing can take several weeks. Follow-up visits with the ophthalmologist are essential to monitor healing and ensure the best possible outcome.

While side effects like glare or haloes around lights may occur, they usually diminish over time. With proper care and adherence to post-operative instructions, cataract surgery significantly improves vision and quality of life for the vast majority of patients.
