How Long After Laser Treatment for Retinal Holes Will Floaters Improve? - Ophthalmology

How long does it take for floaters caused by a retinal tear to improve or disappear after laser treatment?


Due to a sudden onset of a large number of floaters in both eyes at the end of May, a dilated eye examination in mid-June revealed retinal holes in both eyes.
Consequently, retinal laser treatments were performed on both eyes within two weeks.
I would like to ask the doctor, after the formation of scar tissue from the laser treatment for retinal holes that caused the floaters, how long will it take for the floaters to gradually improve after 2 to 4 weeks?

Hello, Stargazing Coffee: Floaters will not disappear due to laser treatment, as floaters originate in the vitreous body, while laser treatment is performed on the retina.
The two are unrelated.
However, floaters may change over time and may decrease in number.
At the Department of Ophthalmology, Puzi Hospital in Taiwan: 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 seek medical attention at a healthcare facility.
I hope to have the opportunity to serve you.

More Info


After undergoing laser treatment for retinal holes, many patients experience concerns regarding the persistence of floaters, a common visual disturbance characterized by small spots or strands that drift across the field of vision. Floaters are typically caused by changes in the vitreous gel that fills the eye, particularly when it begins to liquefy or pull away from the retina, which can happen with age or due to other factors such as retinal tears or holes.

In your case, having undergone laser treatment for retinal holes, it is important to understand that the floaters you are experiencing may not improve immediately after the procedure. The laser treatment itself is designed to create a scar around the retinal hole, which helps to seal it and prevent further complications, such as retinal detachment. However, the floaters may persist for some time as the vitreous continues to change.

Generally, it can take several weeks to a few months for floaters to improve after laser treatment. The timeline can vary significantly from person to person, depending on individual healing processes and the extent of vitreous changes. In many cases, patients report that floaters become less noticeable over time, particularly as the brain learns to ignore them. This phenomenon is known as neuroadaptation, where the brain adjusts to the presence of floaters, making them less distracting.

In the initial 2 to 4 weeks following the laser treatment, you may notice some changes as the scar tissue forms and stabilizes. During this period, it is crucial to monitor your symptoms closely. If you experience any sudden changes in your vision, such as an increase in floaters, flashes of light, or a shadow in your peripheral vision, you should seek immediate medical attention, as these could be signs of complications.

Additionally, it is important to maintain regular follow-up appointments with your eye care provider. They can assess the healing process and provide guidance on managing floaters. If floaters remain bothersome after a few months, there are options such as vitrectomy, a surgical procedure that removes the vitreous gel and can significantly reduce floaters, but this is typically considered only in severe cases due to the associated risks.

In summary, while floaters after laser treatment for retinal holes can be concerning, they often improve over time as the eye heals. Expect a gradual reduction in their prominence over several weeks to months, and keep in close contact with your eye care professional to ensure your recovery is on track. If you have any further questions or concerns, do not hesitate to reach out to your healthcare provider for personalized advice and support.
