Cataract surgery restores clear vision by replacing a clouded natural lens with an artificial one. While generally successful, many individuals experience a burning sensation in their eyes during recovery. This discomfort is common and temporary, often subsiding as the eye heals. Understanding these reasons helps manage expectations.
Understanding Why Your Eyes Burn
The primary reason for a burning sensation after cataract surgery is dry eye, where the eyes do not produce enough tears or tears evaporate too quickly. Small incisions made during surgery can temporarily disrupt corneal nerves involved in tear production, leading to decreased tear secretion and an unstable tear film. This nerve impairment means the eye may not signal dryness effectively, allowing irritation to build. The bright microscope light used during the procedure can also reduce goblet cells, which are responsible for eye lubrication.
Inflammation is another cause of post-surgical burning, a natural body response to surgery. This inflammation can contribute to discomfort and affect the tear film. The healing of the corneal incision itself can also produce unusual sensations. Eye drops prescribed after surgery, essential for preventing infection and reducing swelling, can sometimes cause discomfort due to their ingredients or preservatives. Pre-existing dry eye conditions can also worsen after surgery.
Simple Steps for Relief
Simple at-home measures can provide relief for burning eyes after cataract surgery. Frequent use of preservative-free artificial tears is recommended; these drops lubricate the eye surface and stabilize the tear film, reducing irritation. Wait about 5 to 30 minutes after applying prescribed medicated drops before using artificial tears to avoid diluting the medication. Warm compresses can also soothe the eyes and improve tear film stability.
Maintaining proper hydration by drinking plenty of water helps alleviate dry eye symptoms. Protecting your eyes from environmental irritants such as wind, dust, smoke, and pollen is important during recovery. Wearing wraparound sunglasses outdoors can shield your eyes. Following the prescribed schedule for post-operative eye drops is essential, as these medications control inflammation and prevent complications.
Important Signs to Watch For
While a burning sensation is often a normal part of recovery, certain symptoms warrant immediate contact with your eye doctor. Severe or worsening eye pain not relieved by pain relievers indicates a more serious issue. A sudden decrease or loss of vision, or any significant change in clarity, should be reported without delay. Increased redness that persists, or new or worsening discharge, can be signs of infection.
New flashes of light, a sudden increase in floaters, or a shadow or curtain in your peripheral vision could signal a retinal detachment. Any unusual or concerning symptoms should prompt a call to your eye care professional. Early detection and treatment of these signs can help prevent complications and preserve vision.
