Exploring the Differences between LASIK and Cataract Surgery

Some people often wonder what the difference is between cataract surgery and LASIK. Both of these procedures can improve vision dramatically and let most people live their lives without wearing glasses or contacts. 

However, they are different procedures with distinct purposes. For the best results, choose one that is right for you. Read on below to learn more about what cataract and LASIK surgery are.

What Is Cataract Surgery?

Most people prefer cataract surgery when looking to improve their eyesight. It’s a non-invasive procedure that takes a minimum of two hours in a doctor’s office. 

During the procedure, the doctor will use a knife to cut the eye’s cloudy lens. They will then place a new artificial lens inside the eye, allowing light to pass through it and into the retina, where the image is sent to the brain.

What Is LASIK Eye Surgery?

LASIK eye surgery is a type of corneal refractive surgery that improves vision by adjusting the shape of the cornea. The eye’s cornea is the clear outer part where light enters. The cornea has a particular curvature that allows light to focus on the retina. 

Typically, the cornea’s curvature is as much as a few millimetres different on each side of the eye. The cornea needs to be as close to 20/20 as possible for good vision. That requires a curvature of about one-third of a millimetre over the entire cornea.

During LASIK eye surgery, the doctor uses a device to create a flap in the cornea. They then utilize an instrument to remove the cornea’s tissue, allowing them to flatten it. After making the change, the cornea will revert to its normal shape. While the LASIK procedure is short, it is a very precise and delicate procedure that requires a skilled doctor.

The Difference between LASIK and Cataract Surgery

The main difference between LASIK and cataract surgery is their purpose. While cataract surgery will improve eyesight, LASIK surgery will enhance vision to the best possible potential. 

LASIK eye surgery can provide clear vision without using glasses or contact lenses. It works for people with very poor eyesight due to their cornea being unable to focus light on the retina. Meanwhile, nearsighted or farsighted individuals with a healthy cornea may better opt for cataract surgery.

Additionally, cataract surgery is much less complicated than LASIK eye surgery. The procedure is quick and simple, with only a short recovery time needed afterwards. For LASIK surgery, the healing time is longer and more complicated. Many experience halos and glares, while others may have dry eyes.

Other than that, both can be performed simultaneously. That’s why patients often get cataract and LASIK eye surgery by the same doctor one after the other.

Deciding between Cataract Surgery and LASIK

The main thing that patients need to consider is the current condition of their vision to help them decide between cataract and LASIK surgery. For example, if you are nearsighted or farsighted, cataract surgery may not increase your vision enough. However, if you can see well without glasses but would like to see even better, LASIK eye surgery may be for you.

The other thing that patients need to consider is their current lifestyle. If you enjoy activities such as swimming, running, or playing sports with contact lenses, cataract surgery may not be a good choice. In that case, LASIK eye surgery may be a more wonderful option for you.


When considering cataract surgery or LASIK eye surgery, it’s important to talk to your doctor and discuss which procedure is right for you. Both are prevalent procedures, each with its significant benefits. No matter which surgery you choose, you can experience a dramatically improved quality of life after it is complete.
