What are the complications after cataract surgery?
We now have a deeper understanding of cataracts—a common ophthalmic condition with various types, including complicated cataracts, traumatic cataracts, metabolic cataracts, senile cataracts, and congenital cataracts. Because their underlying causes differ, appropriate preventive measures must be adopted accordingly. So, what are the potential complications following cataract surgery?
What Are the Complications After Cataract Surgery?
Complications following cataract surgery may include infection, intraocular hemorrhage, and other symptoms. Although cataract surgery boasts a very high success rate, no surgical procedure—regardless of how successful—can guarantee a 100% absence of complications. Infection is among the most serious postoperative risks: bacterial or fungal intraocular infection occurs at an overall incidence of approximately 3 per 10,000 cases. Should patients develop symptoms such as ocular redness, swelling, or sudden, severe vision loss, immediate medical intervention is essential to control the infection and preserve visual function. Explosive intraocular hemorrhage, while extremely rare, carries a small but non-negligible risk (approximately several per 10,000 cases); however, if it does occur, it can severely impair vision and requires prompt, aggressive management.

When detected early, most complications are fully treatable. In the majority of cases, topical eye drops suffice for treatment. While bleeding may also occur after other ocular surgeries—including cataract surgery—the volume is typically minimal and rarely affects vision. One of the most common postoperative complications is glaucoma; some patients experience elevated intraocular pressure following surgery, which can be managed medically or surgically. Additionally, certain cataract patients may develop retinal disorders postoperatively, leading to retinal complications. Some of these conditions resolve spontaneously, but most require pharmacological or surgical intervention.

Cataract patients should consume foods rich in zinc, as zinc deficiency promotes cataract formation. Good dietary sources of zinc include herring, sardines, lean meats, peanuts, walnuts, and oysters. We hope this information proves helpful to you.
