What Are The Disadvantages Of Cataract Surgery

Cataract surgery is a common and highly effective procedure that helps improve vision for people with cataracts, which are cloudy areas that form in the lens of the eye.

While cataract surgery offers numerous benefits and has a high success rate, it’s important to be aware of potential disadvantages and risks associated with the procedure. 

The Disadvantages Of Cataract Surgery

Infection Risk

Like any surgical procedure, cataract surgery carries a risk of infection. The eye is a sensitive organ, and any infection can potentially cause serious complications. 

However, the risk of infection is relatively low, and doctors take precautions to minimize this risk by using sterile equipment and providing antibiotics when necessary.

Vision Complications

While most people experience improved vision after cataract surgery, some may encounter issues such as glare, halos, or double vision, especially in low-light conditions. These visual disturbances usually improve over time as the eye heals, but they can be bothersome initially.

Posterior Capsule Opacity

After cataract surgery, a clear membrane called the posterior capsule is left to support the artificial lens implanted during the procedure.

 In some cases, this membrane can become cloudy over time, causing a condition called posterior capsule opacity or “secondary cataract.” This can lead to vision problems similar to those experienced before surgery. However, a quick and painless laser procedure called YAG laser capsulotomy can effectively treat this condition.

Retinal Detachment

Although rare, retinal detachment is a potential complication of cataract surgery. This occurs when the thin layer of tissue at the back of the eye (the retina) pulls away from its normal position. 

If not promptly treated, retinal detachment can lead to severe vision loss. It’s important to be aware of the symptoms, such as sudden flashes of light or a curtain-like shadow over your vision, and seek medical attention if they occur.

Swelling and Inflammation

Some degree of swelling and inflammation in the eye is normal after surgery. However, in some cases, excessive inflammation can lead to discomfort and affect the healing process. Doctors may prescribe eye drops or other medications to manage this inflammation.


Cataract surgery can sometimes increase the risk of developing glaucoma, a condition characterized by increased pressure within the eye. This can potentially damage the optic nerve and result in vision loss. Regular check-ups with your eye doctor are crucial to monitor for any signs of glaucoma after cataract surgery.

Unsatisfactory Visual Outcome

While the goal of cataract surgery is to improve vision, some individuals may not achieve the desired level of clarity or focus. This can be due to factors like underlying eye conditions or complications during surgery. Discuss your expectations with your doctor before the procedure to ensure realistic goals are set.


Cataract surgery is not a free procedure, and the cost can vary depending on the type of surgery and the surgeon’s fees. In the United States, the average cost of cataract surgery is about $3,000 per eye.

How To Reduce The Risk Of Cataract Surgery

  • Choose a qualified surgeon who has experience performing cataract surgery.
  • Get all of your pre-surgery testing done in advance.
  • Follow your doctor’s instructions carefully after surgery.
  • Take all of your medications as prescribed.
  • Report any problems to your doctor right away.

Frequently Asked Questions

Q:  How do I know if I need cataract surgery?

A: If you’re experiencing blurred or cloudy vision, increased sensitivity to light, or difficulty seeing at night, you might have cataracts. An eye doctor can diagnose and recommend surgery if needed.

Q: Is cataract surgery safe?

A: Yes, cataract surgery is generally safe. It’s one of the most common and successful surgical procedures. However, like any surgery, there are risks involved.

Q:  Does cataract surgery hurt?

A: No, cataract surgery is usually painless. Anesthesia is used to numb the eye, and you might feel some pressure or mild discomfort during the procedure.

Q: How long does the surgery take?

A: The surgery itself is often quick, usually around 15-20 minutes. However, you’ll spend some time in the recovery area afterward.

Q: Is cataract surgery done on both eyes at the same time?

A: Usually not. Each eye is operated on separately, with a gap of about a week to a month between surgeries.

Q: How long is the recovery period?

A: Most people can resume normal activities within a day or two after surgery. However, it might take a few weeks for your vision to fully stabilize.

Q: Can I drive after cataract surgery?

A: You might need someone to drive you home after the surgery, as your vision could be blurry at first. Once your doctor gives the green light, you can usually drive again.

Q: Will I still need glasses after cataract surgery?

A: You might still need glasses for reading or certain activities, depending on the type of lens implanted. Some people find that they need glasses less often after surgery.

Q: How long do the artificial lenses last?

A: Artificial lenses are designed to be permanent and usually last a lifetime. However, some people might develop issues over time that require further treatment.

Q: Can cataracts come back after surgery?

A: No, cataracts cannot come back once they’re removed. However, secondary cataracts (posterior capsule opacity) can develop, but these can be easily treated.

Q: Are there alternatives to surgery for cataracts?

A: Surgery is the only effective way to remove cataracts. If cataracts are affecting your daily life, surgery is usually the best option.

Q: How do I prepare for cataract surgery?

A: Your doctor will provide specific instructions, but generally, you might need to stop certain medications, fast before the surgery, and arrange for someone to drive you home afterward.


cataract surgery is a valuable and widely performed procedure that has transformed the lives of millions by restoring clear vision, it’s important for individuals considering the surgery to be aware of the potential disadvantages and discuss them with their eye care professional to make an informed decision based on their specific circumstances and expectations.
