Floaters After Smile Surgery

SMILE (Small Incision Lenticule Extraction) surgery has gained popularity as a refractive procedure for correcting vision issues such as nearsightedness, with or without astigmatism. Although generally safe and effective, rare patients may experience floaters following SMILE surgery, which can raise concerns and impact their newfound visual freedom.

This article delves deep into the phenomenon of post-SMILE surgery floaters, exploring their causes and implications.


Understanding Floaters

Floaters are minuscule specks, delicate threads, or wisps resembling cobwebs that gracefully glide across your visual field. They materialize as a result of alterations in the vitreous humor, the gel-like substance that fills the interior of your eye.

These modifications can be attributed to a multitude of factors, encompassing the natural progression of age, ocular trauma, as well as various eye ailments.


Causes of Floaters After SMILE Surgery

Several factors can contribute to the occurrence of floaters after undergoing SMILE surgery:

  • Inflammation:
    The healing process post-surgery can trigger inflammation in the eye, which can affect the vitreous humor and result in temporary floaters.
  • Pre-existing floaters:
    Individuals who already have floaters may notice an increase in their prominence after surgery, likely due to heightened awareness of their vision.
  • Gas bubbles:
    During the SMILE procedure, a small gas bubble is used to create the lenticule. While these bubbles are typically absorbed quickly, there may be residual bubbles that remain, appearing as floaters.
  • Retinal tear:
    Although rare, SMILE surgery can, in certain cases, cause a tear in the retina. This can lead to sudden flashes of light and an escalation in the number of floaters. Seeking prompt medical attention is imperative in such circumstances.


Are Floaters Common After SMILE?

According to research, the occurrence of floaters after SMILE surgery is relatively rare, affecting less than 5% of patients. However, it’s important to note that individual experiences may differ, and certain factors, such as pre-existing eye conditions or complications during surgery, can potentially elevate the risk.


Types of Floaters and Their Significance

Not all floaters are the same. Their appearance, quantity, and movement can provide insights into their origin and potential risks:

  • Small, translucent floaters:
    These are often harmless and temporary, associated with post-surgical inflammation or pre-existing conditions.
  • Large, dark floaters:
    These can be more worrisome, possibly indicating a buildup of blood or debris in the vitreous humor.
  • A sudden increase in floaters:
    A sudden surge in the number or size of floaters, accompanied by flashes of light or vision loss, may suggest a retinal tear and necessitates immediate medical assessment.


Managing and Treating Floaters

Most floaters that occur after SMILE are temporary and typically fade away within a few weeks or months. However, some tips may help manage them in the meantime:

  • Stay hydrated:
    Maintaining proper hydration can help preserve the consistency of the vitreous humor and potentially reduce the visibility of floaters.
  • Protect your eyes:
    Shielding your eyes from bright light by wearing sunglasses may make floaters less noticeable.
  • Avoid strenuous activities:
    Engaging in heavy lifting or straining can increase eye pressure and exacerbate floaters.
  • Regular eye check-ups:
    It is important to schedule follow-up appointments with your ophthalmologist to monitor your vision and promptly address any concerns. In rare instances where floaters persist and cause visual impairment or indicate a retinal tear, your doctor may recommend the following options:
  • Laser vitreolysis:
    This minimally invasive procedure utilizes laser pulses to fragment and eliminate larger floaters.
  • Vitrectomy:
    In severe cases, surgery might be necessary to extract blood or debris from the vitreous humor.


When to Seek Immediate Medical Attention?

Although most floaters after SMILE are generally not a cause for concern, it is important to promptly seek medical attention if you experience any of the following symptoms:

  • Sudden increase in the number or size of floaters in your vision
  • Flashes of light in your visual field
  • Eye pain or redness
  • Loss of vision
  • Early diagnosis and intervention are crucial in effectively managing serious complications such as retinal tears.


Living with SMILE and Floaters

In the majority of SMILE patients, floaters are a rare and temporary occurrence that typically resolves on its own. By gaining an understanding of the causes, types, and management strategies, you can approach this experience with confidence and fully enjoy the benefits of your improved vision.

Remember, maintaining open communication with your ophthalmologist is crucial for effectively navigating any vision changes that may arise following SMILE surgery.
