Does Lasik Get Rid Of Eye Floaters?

Eye floaters are an intriguing visual phenomenon that can be as frustrating as they are fascinating. 

If you’ve ever noticed tiny specks, threads, or cobweb-like shapes drifting across your field of vision, then you’ve encountered eye floaters firsthand. 

For individuals considering LASIK surgery, a common question arises: does LASIK get rid of eye floaters?

In this blog post, we will dive deep into the relationship between LASIK and eye floaters, exploring what floaters are, their causes, and whether LASIK can effectively address them. Our goal is to provide valuable, well-researched information to help you make informed decisions about your eye care.


Understanding Eye Floaters

What Are Eye Floaters?

Eye floaters are small, shadowy shapes that appear to drift through your vision. They are most noticeable when looking at something bright, like a clear blue sky or a white computer screen. Floaters can take various forms, such as:

  • Black or gray dots
  • Squiggly lines
  • Thread-like strands
  • Cobwebs or rings

Floaters follow your eye movements, yet swiftly dart away when you try to focus on them directly.


Causes of Eye Floaters

Floaters are caused by age-related changes in the vitreous humor—the gel-like substance that fills the inside of your eye. As we age, the vitreous humor starts to liquefy and shrink, causing tiny collagen fibers within it to clump together. These clumps cast shadows on the retina, which we perceive as floaters.

Common causes of floaters include:

  • Ageing: Floaters commonly appear in individuals aged 50 to 75.
  • Myopia: Nearsighted individuals are more prone to floaters.
  • Eye Trauma: Injuries to the eye can lead to floaters.
  • Inflammation: Conditions like uveitis can cause inflammation in the eye, leading to floaters.
  • Posterior Vitreous Detachment (PVD): In the back of your eye, there’s a gel-like substance called the vitreous that normally holds its shape and connects to the retina, the light-detecting layer. PVD occurs when this gel detaches from the retina.


What is LASIK?

Laser-Assisted In Situ Keratomileusis, or LASIK, is a popular refractive eye surgery designed to correct common vision problems such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. 

The procedure entails creating a thin flap in the cornea, using a laser to reshape the underlying corneal tissue, and then repositioning the flap. 

The goal is to improve the eye’s focusing ability, thus reducing dependence on glasses or contact lenses.


LASIK and Eye Floaters – The Connection

Now, let’s address the key question: Does LASIK get rid of eye floaters? The straightforward answer is no. LASIK surgery does not eliminate or treat eye floaters. Here’s why:

1. Different Areas of the Eye

LASIK focuses on the cornea, the eye’s outermost layer, all this to correct refractive errors. In contrast, floaters originate from changes in the vitreous, the gel-like substance within the main cavity of the eye. Since these two areas are distinctly separate, LASIK’s reshaping of the cornea has no impact on the vitreous or the floaters within it.

2. Mechanism of Action

LASIK employs a laser to reshape the corneal tissue, correcting vision problems by improving how light focuses on the retina. In contrast, floaters result from tiny particles moving within the vitreous, casting shadows on the retina. The mechanisms causing floaters and the methods LASIK employs to improve vision are entirely unrelated.

3. Floaters’ Natural Progression

Floaters often diminish over time without any intervention as the brain adapts and learns to ignore them. This process is known as neuroadaptation. LASIK does not influence this natural progression, nor does it accelerate the brain’s adaptation to floaters.


What Can Be Done About Floaters?

While LASIK isn’t a solution for floaters, several other options are available for managing this condition:

1. Observation and Adaptation

In many cases, floaters are benign and do not require treatment. Over time, they may become less noticeable as the brain adapts and learns to disregard them. Regular eye exams can help ensure that the floaters are not symptomatic of a more serious condition.

2. Vitrectomy

For severe cases where floaters significantly impair vision, a vitrectomy can be performed. This surgical procedure entails removing the vitreous humor and substituting it with a saline solution. While effective, vitrectomy carries risks such as retinal detachment and cataracts, and is generally considered only when floaters severely impact quality of life.

3. Laser Therapy

Laser vitreolysis is a less invasive option that uses a laser to break up floaters into smaller, less noticeable fragments. While this procedure is less risky than vitrectomy, it may not be suitable for everyone and is not always 100% effective.

4. Medication and Supplements

Although no medications or supplements can directly eliminate floaters, maintaining overall eye health through a balanced diet and eye-specific vitamins may help reduce the risk of developing floaters in the first place. Omega-3 fatty acids, vitamin C, and antioxidants are known to support eye health.

5. Adapting to Floaters

In many cases, individuals can adapt to floaters over time. Paying less attention to floaters and focusing on other visual tasks can help.


When to See a Doctor

While floaters are generally harmless, there are instances when you should seek medical attention:

  • Sudden Onset: If you experience a sudden increase in floaters or see flashes of light, it could indicate a retinal tear or detachment, which requires immediate medical attention.
  • Vision Loss: Any loss of vision or a curtain-like shadow over your visual field should be evaluated by an eye care professional.
  • Pain and Redness: Floaters accompanied by eye pain, redness, or swelling could signify an underlying inflammatory condition.


Wrapping Up

LASIK is a life-changing procedure for those with refractive errors, offering clear vision and freedom from glasses and contact lenses. However, it is not a cure for eye floaters. Understanding the nature of floaters and exploring alternative treatments can help manage this common issue effectively.

If you are considering LASIK for vision correction, consult with your eye care professional to discuss your specific needs and concerns. For floaters, seeking advice from a retinal specialist can provide you with the best options tailored to your condition.

By staying informed and proactive about your eye health, you can make the best decisions for your vision and overall well-being.
