Red Eye After Smile Surgery

SMILE (Small Incision Lenticule Extraction) has transformed laser vision correction by providing a minimally invasive approach with a markedly reduced chance of post-operative issues, such as red eyes. Though rare, comprehending the potential reasons for red eyes following SMILE and recognising when to consult a professional can empower and reassure individuals contemplating the treatment.


Reduced Risk, Not Zero Risk: A Multifaceted Approach

Compared to traditional LASIK procedures, SMILE offers several advantages that contribute to its lower risk of redness:

  • Minimally invasive approach:
    Unlike LASIK, which involves creating a corneal flap, SMILE uses a femtosecond laser to form a lenticule within the corneal tissue. This eliminates the need for significant disruption to the surface and underlying blood vessels, reducing the likelihood of immediate bleeding and subsequent redness.
  • Pre-operative precautions:
    Many surgeons use specialised eye drops before surgery to narrow blood vessels. This further reduces the risk of bleeding and subsequent redness during the procedure.
  • Quicker recovery:
    SMILE has a faster healing process compared to LASIK because of minimal tissue disruption. This allows the eye to heal faster, shortening the duration of potential redness, if any, during the initial recovery phase.


Understanding Potential Redness: Differentiating Normal from Concerning

Although uncommon, temporary redness may still develop after undergoing SMILE surgery. Here is an analysis of potential factors:

  • Initial irritation:
    Post-surgery, the eyes are naturally sensitive, and the anaesthetic drops utilised in SMILE can cause transient irritation to the ocular surface, resulting in slight redness. This typically subsides within a few hours and generally does not necessitate specific treatment.
  • Broken blood vessels:
    Although infrequent, a few minuscule blood vessels may rupture during the procedure, leading to small red marks on the eye whites (subconjunctival haemorrhage). These marks are benign and usually fade within a few days to a week without requiring intervention.


When to Seek Professional Advice: Prioritising your Eye Health?

While temporary redness is usually normal, it is essential to distinguish it from potential issues that demand immediate medical attention. If you notice any of the following along with redness, consult your surgeon promptly:

  • Severe redness:
    Intense, persistent redness that worsens could signal an underlying problem like infection or inflammation.
  • Pain:
    Eye pain with redness may indicate infection or complications.
  • Loss of vision:
    Any changes in vision, even blurriness or reduced clarity, warrant immediate medical attention.
  • Increased light sensitivity:
    Significant discomfort or sensitivity to light is a concerning symptom requiring professional assessment.


Preventing Infection: Proactive Measures for a Smooth Recovery

Infections post-SMILE are rare, but maintaining excellent hygiene and diligently adhering to your surgeon’s post-op guidance is vital for a smooth recovery. Follow these key steps:

  • Thorough hand hygiene:
    Wash your hands thoroughly and regularly, especially before touching your eyes. This simple practice significantly reduces the risk of introducing bacteria to your eyes.
  • Avoid eye contact:
    Prevent bacteria transfer by refraining from touching your eyes.
  • Use prescribed eye drops:
    Follow your surgeon’s instructions precisely for the correct dosage and frequency. These drops typically include antibiotics to prevent infection, aid healing, and reduce dryness that may contribute to redness.
  • Stay clear of irritants:
    During the initial healing phase, avoid dusty environments, swimming pools, hot tubs, and harsh chemicals that can irritate your eyes and heighten infection risks.


Final Reflection

Following SMILE surgery, although rare, red eyes may occur temporarily. Recognising potential causes and signs of complications is vital. Adhering to your surgeon’s guidance, maintaining hygiene, and promptly seeking medical help if needed enhance the chances of a smooth recovery.

Remember, maintaining open communication with your surgeon is key. Do not hesitate to ask questions, share concerns, and seek clarification about your unique situation. Their expertise significantly impacts your recovery and provides reassurance throughout your journey to a clearer vision.

By following this detailed advice and emphasising transparent communication with your surgeon, you can approach SMILE surgery confidently. Experience improved vision benefits with minimal discomfort and risk.
