However, some people who undergo eye surgery such as LASIK say they see floaters afterward. SEE RELATED: Eye floaters and flashes: What's the difference? Other surgery that can result in floatersĪs mentioned earlier, eye surgery typically doesn't cause floaters. In severe cases, the original IOL may need to be replaced with a new one to eliminate persistent dysphotopsias. But if they are persistent and bothersome, see your cataract surgeon. In most cases, flashes of light in the eye after cataract surgery disappear in a relatively short period of time. Some researchers say up to 50% of patients experience some form of dysphotopsia in the first few days following cataract surgery. Positive and negative dysphotopsias are associated with the material, design and placement of the IOL used in cataract surgery. In some cases, people may notice shadows ( negative dysphotopsias) rather than light flashes in their peripheral vision after surgery. When light flashes ( positive dysphotopsias) occur after cataract surgery, they usually appear briefly in your peripheral vision or slightly off to the side of objects you’re looking at. Light flashes and other unwanted images, or dysphotopsias, are fairly common in the first hours and days after the procedure. SEE RELATED: Eye floaters and flashes FAQ Light flashes after cataract surgeryĮye floaters aren’t the only nuisance that can be experienced after cataract surgery. When the cataracts are removed and more light is clearly focused on the retina again, the eye floaters cast darker, clearer shadows, making them more visible than before. Compare it to how well you cast a shadow on a sunny day compared to an overcast or cloudy day. Because the level of light is reduced, the floaters don’t cast much of a shadow, making them less visible. When light enters the eye, these opaque bits of collagen cast a shadow on the retina that creates the appearance of floaters.Ĭataracts scatter light and therefore reduce the amount and clarity of light focused on the retina. Rather, floaters were already present in the eye but obscured by the cataract, and after clear vision is restored by the surgery, the floaters become more visible.Įye floaters are caused by tiny clumps of a protein called collagen that are suspended in the vitreous (the gel-like substance within the eye). That does not mean cataract surgery is the cause of eye floaters. While this is the result eye surgeons strive for, it’s common for patients to complain of eye floaters after cataract surgery. When the eye’s natural lens becomes cloudy due to aging or other factors, it is removed and replaced with a clear intraocular lens (IOL) to bring things back into focus.Īfter cataract surgery, vision is much clearer and sharper than before. Eye floaters after cataract surgeryĬataract surgery is a very common procedure to restore vision. Plus, the procedure that can bring relief from those pesky eye floaters. Learn why eye floaters are seen so often after common eye procedures such as cataract surgery, and which eye surgeries can bring eye floaters into focus. So, why are eye floaters so common after eye surgery? Many times, eye floaters are already present and become more noticeable once your vision improves. With every vision procedure, however, there are also potential risks and side effects that may occur, with eye floaters being one of the most common. Whether it’s cosmetic or a means of preserving your eyesight, vision surgery can offer a solution to many eye-related issues. There are many reasons an individual may have eye surgery.
