Post-Vitreous Surgery: Is Floaters Normal? - Ophthalmology

Share to:

Post-vitrectomy


Hello Doctor: On February 17, I underwent a minimally invasive vitrectomy due to vitreous hemorrhage in my left eye, which was found to be caused by a small retinal tear.
In the days following the surgery (as of February 22), the air bubble in my eye has gradually decreased in size, but I have noticed some small floaters, such as tiny dots and lines.
Is this normal? I have heard that after a vitrectomy, there shouldn't be any more floaters, so I would like to inquire about this.

Hello: The appearance of small floaters in your vision is a normal phenomenon and is one of the common symptoms following a minimally invasive vitrectomy.
These floaters may be due to residual vitreous or blood clot tissue after the surgery.
Over the course of a few days or weeks post-surgery, the floaters may gradually diminish, and your eyes will adapt to them, typically not causing significant impact on your vision.
However, if you experience a sudden increase in the number of floaters or if they become very prominent, or if you have other unusual symptoms such as eye pain, blurred vision, or flashes of light, it is advisable to seek medical attention immediately to rule out any other ocular issues.

More Info


After undergoing a vitrectomy for vitreous hemorrhage, it is not uncommon for patients to experience floaters, which are small spots or lines that appear in your field of vision. This phenomenon can be particularly concerning for patients who have just had surgery, as they may have been informed that the procedure would eliminate such visual disturbances. However, it is important to understand the nature of floaters and the healing process following vitrectomy.

Floaters are typically caused by changes in the vitreous gel, which fills the eye. During vitrectomy, the surgeon removes the cloudy vitreous gel that may be causing vision problems, and in its place, a saline solution or gas bubble is often introduced. As the eye heals, the remaining vitreous gel can condense and pull away from the retina, leading to the appearance of floaters. These floaters can take various forms, such as small dots, lines, or cobweb-like structures, and they may be more noticeable against bright backgrounds or when looking at a clear sky.

In your case, the appearance of these floaters a few days post-surgery is generally considered normal. The fact that the air bubbles in your vision are diminishing is a positive sign of healing. However, it is essential to monitor your symptoms closely. If you notice a sudden increase in the number of floaters, flashes of light, or any significant changes in your vision, you should contact your ophthalmologist immediately. These could be signs of complications, such as retinal detachment, which requires prompt medical attention.

The healing process after vitrectomy can vary from person to person. While some patients may experience a gradual reduction in floaters over time, others may continue to see them for an extended period. In many cases, patients report that floaters become less bothersome as they adjust to their new visual environment.
To aid in your recovery, it is crucial to follow your surgeon's post-operative care instructions. This may include avoiding strenuous activities, protecting your eyes from bright lights, and attending follow-up appointments to monitor your healing progress. Your doctor may also recommend specific exercises or visual therapies to help your eyes adjust and improve your overall comfort.

In summary, the presence of floaters after vitrectomy is generally a normal part of the healing process. While they can be bothersome, they often diminish over time. However, remain vigilant for any changes in your vision and maintain open communication with your healthcare provider to ensure a smooth recovery. If you have any further concerns or questions about your symptoms, do not hesitate to reach out to your ophthalmologist for personalized advice and support.
