Cataract surgery is common, but understanding the potential complications is crucial for a smooth recovery. Stay informed about post-operative issues to ensure optimal eye health.
Cataract surgery is one of the most common eye procedures, and while it is very safe, patients may still experience a few complications during recovery. Being aware of potential issues helps you know what to watch for and when to call our eye doctors for guidance. It is important to recognize the signs early to protect your eye health and ensure the smoothest recovery possible.
After cataract surgery, a variety of problems, ranging from mild to serious, may occur. Most issues are temporary and resolve on their own, but some require medical attention to prevent lasting damage. Here’s the thing: knowing what complications look like can empower you during your recovery, and following aftercare instructions is key.
Infections can occur after any surgical procedure, and cataract surgery is no exception. The risk increases if proper wound care and aftercare guidelines are not followed. One serious type of infection is endophthalmitis, which occurs when microorganisms enter the eye after the operation. Symptoms include:
If you notice these signs, it is critical to contact our eye doctors immediately for appropriate treatment, often initiated with antibiotics. Inflammation, on the other hand, is a common response following surgery, especially if a larger or denser cataract was removed. Although inflammation is usually temporary, persistent inflammation can delay healing and must be monitored closely.
Swelling and pain in the eye are typical after cataract surgery. These symptoms often result from the natural healing process and may be managed with over-the-counter pain relief medications such as NSAIDs. Small amounts of swelling are expected as the eye adjusts to the new intraocular lens (IOL) and recovers from the procedure. However, if either swelling or pain begins to worsen, or if you experience new discomfort, it is a sign that something might be off, and you should reach out to our office immediately.
It is not unusual to have increased light sensitivity following cataract surgery. Many patients find that their eyes are more sensitive to sunlight and artificial light for several weeks after the procedure. Wearing sunglasses can help during this period, but if light sensitivity becomes severe or is accompanied by other symptoms such as pain or significant vision changes, it might indicate a more serious problem like inflammation or even an infection. Blurred vision is also a common side effect, often noticed in the days or weeks after surgery. In the beginning, blurry vision may be due to swelling or the adjustment to the new artificial lens. The condition is expected to improve gradually; however, if it persists beyond a week or so, a follow-up with our eye doctors is warranted.
Many individuals experience dry eyes after cataract surgery. This occurs because the tiny nerves that signal your eye to produce tears can be affected during the incision process. For most people, dry eye symptoms are mild and temporary, lasting anywhere from a few weeks to three months. The discomfort may feel like a sand-like sensation in the eye, but using preservative-free artificial tears can help manage the dryness. If the sensation of dryness or grittiness continues or worsens, our team can recommend additional treatments to soothe your eyes during the healing process.
Following cataract surgery, some patients notice the appearance of floaters or small dots and lines in their vision. These are usually caused by the natural movement of the vitreous gel inside the eye and often become more noticeable after the cloudy lens has been replaced with a clear intraocular lens. In addition, certain patients experience unwanted visual phenomena, such as glare, halos, or streaks of light—a condition known as dysphotopsia. Positive dysphotopsia refers to these extra flashes and halos, which may appear more prominently at night. Negative dysphotopsia, where a patient sees a crescent-shaped shadow or arc of light, also occasionally occurs. Although these visual disturbances can be bothersome, they typically improve on their own as your eyes adjust. Should these unwanted images persist for more than three to four months, follow-up with our eye doctors is essential to explore possible treatment options.
The insertion of an intraocular lens during cataract surgery is a precise part of the procedure. In rare cases, however, the new lens can shift from its intended position. A dislocated IOL can lead to symptoms such as double vision, continued blurry vision, or even a loss of sight in the affected eye. This misalignment can be caused by surgical trauma or previous damage to the eye. When this happens, it may require additional surgery to reposition the lens or, in some cases, replace it altogether.
One of the more common long-term complications emerging after cataract surgery is posterior capsule opacification, often referred to as a “second cataract.” During the original procedure, the cataract is removed, but the thin membrane (the lens capsule) remains intact to support the artificial lens. Over time, in some patients, residual cells on this capsule can become cloudy, leading to a gradual decline in vision clarity. PCO can develop weeks, months, or even years after the initial surgery. Treatment is straightforward—a quick, painless laser procedure called YAG laser capsulotomy creates an opening in the cloudy capsule, usually resulting in almost immediate improvement in vision.
It is not uncommon for the eyelid to become droopy, a condition known as ptosis, after cataract surgery. The use of a speculum to keep the eye open during the surgery alongside postoperative swelling may contribute to this condition. Fortunately, ptosis typically resolves on its own within several months, with most patients noticing improvement within six months. If the droopy eyelid persists and affects vision, further evaluation may be necessary to explore corrective measures.
Some patients may experience ocular hypertension, which means an increase in the pressure inside the eye. This can feel like pressure or even mild discomfort and, if left unchecked, can lead to further complications such as glaucoma. Fortunately, our eye doctors routinely check ocular pressure after the surgery, particularly in patients who have additional risk factors like pre-existing glaucoma or diabetes. Timely treatment with medications or other interventions can help manage this condition and prevent long-term damage.

The posterior capsule is a vital part of the eye that holds the new intraocular lens in place. In some instances, this capsule can tear during the surgery—an event known as a posterior capsule rupture. This tear may lead to the loss of vitreous fluid into the front part of the eye, which increases the risk of several serious issues like retinal detachment. Recognizing early signs of a rupture is key. Signs that your posterior capsule may have been compromised include a sudden deepening of the anterior chamber or unexpected shifts in the lens material. When these signs are noted, additional steps such as an anterior vitrectomy may be necessary to manage the situation and protect your vision.
Cystoid macular edema is another serious complication that most frequently occurs around six to eight weeks after cataract surgery. This condition involves the accumulation of fluid in the central part of the retina (the macula) due to leakage from blood vessels. With modern surgical techniques, CME is relatively rare, affecting only a small percentage of patients. However, when it does occur, it can result in decreased central vision and the presence of blind spots. Diagnostic tools such as OCT (optical coherence tomography) help in assessing the condition, and timely treatment is essential to reduce the impact on your vision.
Retinal detachment is one of the more dangerous complications associated with cataract surgery, though it is rare. The retina is the light-sensitive layer at the back of the eye, and if it begins to peel away from its normal position, vision loss can occur rapidly. Warning signs include:
If any of these symptoms occur, it is crucial to seek help immediately as retinal detachment is a medical emergency. While prompt surgical intervention can often restore vision, delays in treatment increase the risk of permanent vision loss.
Though uncommon, bleeding inside the eye can occur as a complication after cataract surgery. Such hemorrhages are serious and need to be addressed quickly to prevent further damage. The risk of bleeding increases in patients with underlying conditions like high blood pressure, diabetes, or atherosclerotic vascular disease. Any significant amount of bleeding after surgery should be reported to our eye doctors immediately for further evaluation and treatment.
Endophthalmitis, a severe infection within the eye, represents one of the more dangerous complications following cataract surgery. Although it is very rare, its potential impact on vision is significant. Risk factors include a rupture of the posterior capsule during surgery or other intraoperative complications. The infection may progress quickly, so patients should promptly report any signs of increasing pain, redness, or vision loss. Our eye doctors can initiate aggressive treatment with antibiotics to control the infection and protect your vision.
It is common to experience a range of temporary side effects after cataract surgery. These include a persistence of blurred vision, light sensitivity, and even a sensation of something in the eye. For instance, the initial blurry vision often results from postoperative swelling or the time needed for your brain to adjust to the new lens. Similarly, a feeling akin to having a foreign body or the sensation of dryness can occur as your eye heals from the incisions. Rest assured, most of these effects wane as the eye recovers.
Some patients might feel dizziness or slight nausea after their surgery. This is often linked to the anesthetic eye drops used during the procedure or the body’s response to having undergone surgery. For most, these feelings are mild and resolve once you are fully awake and start hydrating and eating regular meals. If these symptoms continue for several days or become more pronounced, it is best to get in touch with our eye doctors to ensure there is no underlying issue affecting your recovery.
A red or bloodshot eye after cataract surgery is not uncommon. Most of the time, this redness is due to minor inflammation or a small subconjunctival hemorrhage, which occurs when a tiny blood vessel breaks. Though the red spot can appear alarming, it is usually harmless and resolves on its own within a few weeks. However, if you experience additional symptoms such as pain, severe light sensitivity, or a sudden change in vision alongside the redness, contacting our eye doctors immediately is important for further examination.
