Why do I still see shadows after laser treatment?


Hello, Doctor He.
I had laser treatment for floaters a week ago, but I can still see shadows.
Is this normal? The doctor who treated me said my floaters were caused by retinal detachment, which led to the leakage of the vitreous gel in my eye.
(He explained it very professionally; I translated it into my own understanding.) The ophthalmologist performed laser surgery to repair my retina.
However, he mentioned that the shadows from the floaters would not disappear immediately and would gradually fade away over time.
He said as long as the shadows do not increase or I do not experience flashes of light, the treatment is considered complete.
Is this true? I found many articles shared by others online stating that the shadows disappear right after laser surgery, which contradicts what my ophthalmologist said.
Which one is correct? Should I seek a second opinion from another ophthalmologist? Do you have any good advice for me? Thank you!

The term "floaters" generally refers to the shadows we see, which are not affected by laser treatment and therefore do not disappear.
Another situation is when the shadow is caused by a localized retinal detachment; after laser treatment, some parts may reattach, and this type of shadow can disappear.
This is for your reference.

More Info


After undergoing laser treatment for floaters, it is not uncommon to still perceive shadows or "floaters" in your vision. This can be a source of confusion and concern, especially when the expectations set by your doctor and the experiences shared by others seem to differ significantly.
Firstly, it's important to understand what floaters are. Floaters are tiny clumps of gel or cells that form in the vitreous, the clear gel-like substance that fills the eye. As we age, the vitreous can shrink and become more liquid, leading to the formation of these floaters. In some cases, they can be exacerbated by conditions such as retinal tears or detachments, which may have been the case for you, as your doctor indicated that your floaters were related to retinal issues.

The laser treatment you received is designed to address these floaters, particularly when they are associated with retinal tears or detachments. The procedure works by using laser energy to break up the floaters or to seal retinal tears, which can help prevent further complications. However, it is crucial to recognize that the resolution of floaters does not happen immediately. Your doctor’s statement that the shadows may take some time to disappear is accurate. The process of the vitreous gel reorganizing and settling can take weeks to months, and during this time, you may still see floaters or shadows.

It is also worth noting that the perception of floaters can sometimes increase after treatment. This can be due to the changes in the vitreous gel and the way light interacts with it post-treatment. The fact that your doctor mentioned that as long as the floaters do not increase or if you do not experience flashes of light, the treatment is considered successful, is a reassuring sign. Flashes can indicate further retinal issues, so monitoring for those is essential.

If you are still experiencing significant discomfort or if your symptoms worsen, it is reasonable to seek a second opinion from another ophthalmologist. Different doctors may have varying approaches and insights, and it can be beneficial to have multiple perspectives on your condition. However, it is also important to give your eyes some time to adjust after the treatment.

In summary, seeing shadows or floaters after laser treatment is not unusual and can be part of the healing process. Your doctor’s advice to monitor the situation and to be alert for any new symptoms is sound. If you have ongoing concerns or if your symptoms change, do not hesitate to reach out to your healthcare provider for further evaluation. Remember, your vision is vital, and ensuring its health is paramount.
