Experiencing red eyes after LASIK surgery is a common concern and a normal part of the healing process. This temporary side effect occurs as the eyes adjust to the changes from the procedure. This article explains the reasons behind post-LASIK redness and offers practical strategies for managing this temporary condition, helping you navigate your recovery with greater ease.
Why Your Eyes Appear Red
Redness after LASIK stems from several physiological responses. One common reason is a subconjunctival hemorrhage, appearing as red splotches on the white part of the eye. This occurs when tiny, fragile blood vessels on the eye’s surface rupture due to pressure or manipulation during corneal flap creation, similar to a minor bruise. These spots are not painful, do not affect vision, and usually resolve within a few weeks.
Dry eyes are another frequent cause of redness, reported by 50-95% of patients. The procedure can temporarily disrupt nerves in the cornea responsible for tear production, leading to insufficient lubrication, irritation, and redness. This dryness can also cause discomfort, itching, and a gritty sensation. Additionally, the body’s natural healing process can cause temporary corneal inflammation, increasing blood flow and resulting in visible redness.
At-Home Strategies for Relief
Managing red eyes at home involves supporting natural healing and maintaining lubrication. Frequent use of preservative-free lubricating eye drops, or artificial tears, is recommended to alleviate dryness and irritation. These drops moisturize the eyes and support the tear film; some professionals suggest frequent use initially, gradually reducing frequency.
Protecting the eyes from environmental irritants is also beneficial. Wearing sunglasses outdoors can shield sensitive eyes from bright light and UV rays, which can exacerbate discomfort. Avoiding dusty or smoky environments, and refraining from swimming pools or hot tubs for at least a week, helps prevent irritation and infection. Limiting eye strain by taking breaks from screens (following the 20-20-20 rule) and avoiding prolonged reading can reduce fatigue and prevent redness from worsening.
Ensuring proper rest and sleep is important for overall healing and can reduce eye strain. Applying a clean, soft, cold compress gently over closed eyelids for 10-15 minutes, a few times a day, may help reduce swelling and provide soothing relief, but direct pressure or ice should be avoided. Always adhere to specific post-operative instructions provided by your surgeon, as these guidelines are tailored to your individual recovery and are important for optimal healing.
When to Seek Professional Guidance
While temporary redness is a common part of LASIK recovery, certain symptoms warrant immediate medical attention. Contact your surgeon if you experience sudden, severe, or increasing eye pain that does not subside. Any significant or unexpected vision changes, such as worsening blurriness, decreased visual acuity, or persistent halos and glare, require prompt evaluation.
Other concerning signs include eye discharge, increased sensitivity to light that is more pronounced than typical post-operative sensitivity, or swelling around the eye. If redness worsens, persists for an extended period, or is accompanied by fever, these could indicate an underlying issue that needs professional assessment. Following your surgeon’s advice helps address potential complications swiftly.
