How long does it take for the symptoms of floaters caused by a retinal tear to improve after laser treatment?


At the end of May, I suddenly experienced a significant increase in floaters, so I went to the clinic for an examination in mid-June.
After a dilated eye exam, it was found that there were holes in the retinas of both eyes.
Consequently, I underwent laser repair for both eyes within two weeks.
I would like to ask the doctor: After the laser repair for retinal holes, how long does it typically take for the floaters caused by the retinal holes to gradually improve and potentially disappear, considering the scar tissue formation occurs 2 to 4 weeks post-procedure?

Hello, Stargazing Coffee: Floaters will not disappear due to laser treatment because floaters originate in the vitreous body, while the laser is applied to the retina.
The two are not related.
However, floaters may change over time, and it is possible for them to decrease in number.
At the E-Hospital in Puzi, Taiwan, the ophthalmology department is open on Monday, Tuesday, Thursday, and Friday mornings from 8:00 AM to 12:00 PM, and Wednesday afternoons from 2:00 PM to 4:30 PM.
Online responses can only serve as a reference; it is necessary to visit a medical institution for treatment.
We hope to have the opportunity to serve you.
Sincerely, Dr.
Gao Pilin.

More Info


After undergoing laser repair for retinal holes, it is common to experience floaters, also known as "muscae volitantes." These floaters are often caused by the changes in the vitreous gel of the eye, which can occur after the laser treatment. The timeline for improvement can vary significantly from person to person, but I can provide some general insights based on medical knowledge.

Typically, after laser treatment for retinal holes, the body begins to heal and form scar tissue within a few weeks. The initial phase of healing, where you might notice an increase in floaters, usually occurs within the first 2 to 4 weeks post-treatment. During this time, the floaters may seem more prominent as the vitreous gel continues to shift and settle.
As the healing progresses, many patients report a gradual decrease in the visibility of floaters over the following months. However, it is important to note that while some floaters may diminish or become less bothersome, others may persist. This is because floaters are often a result of the natural aging process of the eye, and once they form, they may not completely disappear.
In terms of the timeline for improvement, many patients notice a reduction in the prominence of floaters within 3 to 6 months after the laser procedure. However, some individuals may continue to experience floaters for a longer duration. It is essential to have realistic expectations and understand that while floaters can become less noticeable, they may not entirely resolve.

If you find that your floaters are significantly impacting your vision or daily life, it is advisable to discuss this with your ophthalmologist. They can assess your specific situation and determine if any further intervention is necessary. In some cases, if floaters are particularly bothersome, a procedure called vitrectomy may be considered, where the vitreous gel is removed to alleviate the floaters. However, this is typically reserved for severe cases due to the associated risks.

Additionally, it is crucial to monitor for any changes in your vision, such as flashes of light or a sudden increase in floaters, as these could indicate complications that require immediate medical attention. Regular follow-up appointments with your eye care provider will help ensure that your recovery is on track and that any concerns are addressed promptly.

In summary, while floaters may take several weeks to months to improve after laser repair for retinal holes, individual experiences can vary. It is essential to maintain open communication with your eye care professional throughout your recovery process to ensure the best possible outcome for your vision.
