Possible Complications Following Cataract Surgery

Retinal Detachment

There is a 1% risk of retinal detachment after cataract surgery. If this occurs, it can usually be repaired by a retina specialist with surgery, with a success rate of over 94%.

Retinal Swelling

Swelling of the retina can occur in about 1% of patients. This is typically treated with eye drops, but if the swelling persists, further treatment by a retina specialist may be necessary.

Lens Issues

The artificial intraocular lenses (IOLs) used in cataract surgery are generally safe and stable inside the eye. However, in less than 1% of cases, the lens may need to be repositioned, exchanged, or replaced. We use precise calculations to determine the optimal lens power to meet your visual goals, but it’s important to understand that we cannot guarantee perfect results. Some patients may end up more nearsighted, farsighted, or have more astigmatism after surgery. These conditions can usually be corrected with glasses, contact lenses, or additional procedures like IOL exchange or LASIK/PRK surgery.

Optical Side Effects

All IOLs carry the potential for optical side effects, such as glare, halos, or a flickering effect, particularly around the edges of your vision. These are common during the first few hours or days after surgery and typically resolve on their own. In rare cases, if symptoms persist, additional treatments or procedures may be needed to address these side effects.

Cataract Support Issues

In rare cases (less than 1 in 1,000 surgeries), the cataract may lack enough support during surgery and could fall into the back of the eye. If this happens, a retina specialist would need to perform additional surgery to complete the cataract removal.

Corneal Complications

The cornea may become swollen or cloudy after cataract surgery, but this typically resolves within one to two weeks. In less than 1 in 2,000 cases, the cloudiness may persist, requiring a corneal transplant to restore clear vision.

Serious Complications

The most serious, but rare, complications include infection, inflammation, or bleeding inside the eye. These occur in fewer than 1 in 3,500 surgeries and can lead to vision loss, though this is extremely uncommon.

Eyelid Drooping

In less than 1% of cases, patients may experience mild drooping of the upper eyelid after cataract surgery. If the eyelid drooping becomes problematic, a corrective procedure can be done about 3 to 4 months after the surgery.

While these complications are rare, it’s important to be fully informed about the potential risks. We will discuss your individual situation in detail during your consultation, and together we’ll create a plan that aligns with your specific needs and goals for the surgery.
