The hours immediately following cataract surgery play a vital role in how well your eyes heal and how quickly your vision stabilises. Cataracts occur when the eye’s natural lens becomes cloudy, often due to ageing, leading to blurred vision, glare sensitivity, and difficulty performing daily tasks. With cataracts affecting millions globally, modern cataract surgery has become one of the safest and most successful medical procedures. However, experts stress that proper aftercare is just as important as the surgery itself. According to ophthalmologist Dr Thanemozhi Srinivasan, the first 48 hours after cataract surgery are particularly delicate, as the eye incision is still healing and vulnerable to infection, inflammation, and pressure changes. Careful attention during this period can significantly improve recovery outcomes and long-term eye health.
During cataract surgery, the cloudy lens is replaced with an artificial intraocular lens through a tiny incision that heals naturally without stitches. While the procedure is quick and minimally invasive, the eye remains sensitive for the first two days. Dr Srinivasan explains that most post-surgical complications occur due to poor early care, making it essential to follow medical advice strictly during this window.
Patients are advised to rest adequately after surgery and maintain a safe sleeping position. Lying on the back or on the side opposite the operated eye helps minimise pressure, while keeping the head slightly elevated promotes comfort. Wearing the protective eye shield at night is crucial to prevent accidental rubbing during sleep.
Strict adherence to prescribed eye drops is another key factor in recovery. Antibiotic and anti-inflammatory drops help prevent infection and control swelling. Hands should be washed thoroughly before application, the dropper tip should never touch the eye, and a gap of at least five minutes should be maintained between different medications.
Keeping the eye clean is also important. Any mild discharge can be gently wiped away using sterile cotton dipped in cooled boiled water, always cleaning from the inner corner outward and using fresh cotton each time. Protective eyewear such as sunglasses or eye shields should be worn outdoors to shield the eye from dust, wind, bright sunlight, and accidental contact.
Mild discomfort, watering, or a gritty sensation is normal after surgery and usually settles within a few days. If required, mild pain relief such as paracetamol or ibuprofen may be used, along with prescribed eye medications.
Equally important are the activities to avoid during the first 48 hours. Bending forward, stooping, or lifting heavy objects can increase pressure inside the eye and interfere with healing. Rubbing or touching the eye should be strictly avoided, even if itching occurs, as this can introduce bacteria and raise the risk of infection.
Patients should also keep water, soap, shampoo, and cosmetics away from the eyes for at least two days. Eye makeup should be avoided for several weeks, as recommended by the doctor. Driving immediately after surgery is discouraged due to temporary visual blur, and patients should wait for medical clearance before resuming driving.
Swimming pools, hot tubs, and saunas must be avoided, as water in these environments can harbour harmful bacteria that may lead to serious eye infections. While mild redness, light sensitivity, watering, or small floaters are common and usually resolve on their own, patients should remain alert.
Immediate medical attention is necessary if there is increasing pain, worsening vision, flashes of light, a sudden increase in floaters, or a curtain-like shadow across the field of vision. Early reporting of these symptoms can prevent severe complications and protect eyesight.
