There are a number of reasons that people undergo vitrectomy eye surgery, and one of these is a condition known as ‘floaters.’
Floaters are small pieces of debris that float in the vitreous humour, a clear jelly like substance that fills the part of the eyeball between the lens and the retina. Floaters become more common as you get older as a normal part of the aging process.
Floaters cast a shadow onto the retina and sufferers are sometimes able to see this shadow as a back dot, a cloud-like spot, or a long narrow strand.
Floaters are harmless and in many cases don’t affect vision as the brain learns to ignore them. However, if floaters get stuck in your line of vision and don’t move, or they become clustered together, severely affecting your ability to see, vitrectomy eye surgery may be recommended.
During vitrectomy eye surgery the vitreous humour of the affected eye will be removed, along with any floaters, and will be replaced with saline solution.
Vitrectomy eye surgery is rarely recommended for floaters unless they are having a dramatic impact on your vision, because there are some risks associated with the procedure.
