Most cataract surgeries are successful in treating the condition, but there are some cataract surgery complications to be aware of. One of the most serious complications is called posterior capsule opacity, or PCO, which causes blurry vision after the surgery. There is also a risk of experiencing retinal detachment, infections, bleeding, or vision loss after undergoing cataract treatment. Additionally, there are various temporary symptoms that should go away shortly afterward, including redness, itchiness, blurry vision, and swollen eyelids.
One of the most common cataract surgery complications is posterior capsule opacity, also frequently called PCO. During cataract surgery, the lens of the eye is replaced with an intraocular lens implant, placing it into the original capsule in the eye. Unfortunately, the capsule may be damaged during the surgery, causing hazy, blurred vision instead of the clear vision that typically results. The good news is that this issue can be repaired with another surgery that just removes the capsule altogether, leading to clear vision in most cases.
Other cataract surgery complications include those that are often risks after any surgery, such as excessive bleeding or infections. Loss of vision, double vision, or eye inflammation can also all occur, though such issues may sometimes be repaired with further surgery. One of the most serious and well-known cataract surgery complications is retinal detachment, which may not occur for several months after the operation. The most common symptoms of retinal detachment include a sudden increase in floaters and light flashes, as well as vision loss in one part of the eye. If caught early, this issue can usually be treated, but it may lead to total vision loss if ignored.
Like many other types of operations, there are some temporary cataract surgery complications that may occur afterward. For example, some patients may notice blurry vision directly after the surgery, but it should clear up soon after, resulting in clearer vision than before the operation. Additionally, the eyes may feel itchy and seem like they are stuck closed, and some patients also sometimes feel pain or discomfort for the first few weeks after the operation. Another one of the most common temporary cataract surgery complications is redness of the eyes, usually along with a feeling that there is debris in them. The good news is that these symptoms usually disappear within weeks or even days of the surgery, and can often be treated by an eye doctor if they seem to persist.
