Laser Treatment for Floaters: Are There Hidden Risks? - Ophthalmology

Retinal laser treatment without scarring?


Hello, Doctor.
In the past, I visited a small clinic to check for floaters and underwent retinal laser treatment.
(Later, I found out that this clinic had numerous negative reviews.) However, subsequent examinations at several other hospitals did not reveal any signs of laser treatment.
I later inquired with the original ophthalmologist, who mentioned that the tear was located very peripherally and required a three-mirror lens to be seen.
I would like to know if it is possible for laser treatment to leave such subtle traces? Is it possible that there was actually no laser treatment at all? Could this type of laser treatment cause harm to the eyes, such as an increase in floaters or retinal degeneration? I am quite worried and unsure about what the previous eye clinic did.
Could there be any adverse effects on my eyes? Thank you, Doctor.

Hello, if it is located very peripherally, a 3-mirror lens must be used to visualize it.
Therefore, not seeing any traces does not necessarily mean that the procedure was not performed; it simply means it was not visible.
Please rest assured that peripheral laser treatment will not have any adverse effects.

Hello! Thank you for your detailed question regarding your concerns about laser treatment for floaters and the potential risks associated with it. It's understandable to feel anxious about your eye health, especially after experiencing a treatment that may not have been performed in a reputable setting.

Firstly, let's discuss the nature of laser treatment for floaters. Laser vitreolysis is a procedure that aims to reduce the visibility of floaters by using a laser to break them apart. This treatment is generally considered safe, but it is not without its risks. Potential complications can include retinal tears, retinal detachment, and increased floaters, among others. However, these complications are relatively rare when the procedure is performed by an experienced ophthalmologist.

Regarding your concern about the visibility of laser marks in your eye, it is indeed possible for laser treatment to leave minimal or no visible signs, especially if the treatment was aimed at peripheral areas of the retina. The use of specialized lenses, such as the three-mirror lens you mentioned, is often necessary to visualize certain areas of the retina, particularly those that are not easily accessible. If the laser was applied to a very peripheral area, it might not be easily detected during a routine examination, especially if the examining physician is not using the appropriate tools.

Now, concerning your worry about whether the previous clinic performed the laser treatment correctly or at all, it is difficult to ascertain without a thorough examination by a qualified eye care professional. If you have undergone subsequent examinations at reputable hospitals and no signs of laser treatment were found, it raises the possibility that either the treatment was not performed or that it was done in a way that did not leave significant traces.

As for the potential for harm from the laser treatment, if it was performed correctly, the risks should be minimal. However, if there were any complications, such as an undetected retinal tear, it could lead to further issues, including increased floaters or even retinal detachment. If you experience any new symptoms, such as sudden increases in floaters, flashes of light, or a shadow in your vision, it is crucial to seek immediate medical attention.

In terms of long-term effects, while some patients report an increase in floaters after laser treatment, this is not universally the case. Many patients find relief from their symptoms, while others may experience no change or even a worsening of their condition. It is essential to have realistic expectations regarding the outcomes of such treatments.

Given your concerns, I recommend scheduling a comprehensive eye examination with a reputable ophthalmologist who specializes in retinal health. They can perform a thorough assessment of your retina, check for any signs of previous treatments, and address any potential complications. Additionally, they can provide you with information on managing floaters and discuss any further treatment options if necessary.

In conclusion, while laser treatment for floaters can be effective, it is essential to ensure that it is performed by a qualified professional in a reputable setting. If you have doubts about the treatment you received, seeking a second opinion from a trusted eye care provider is a wise decision. Your eye health is paramount, and addressing your concerns with a professional will help alleviate your worries and ensure that you receive the best care possible. Thank you for your question, and I wish you the best in your journey toward better eye health!
