If you’re ready to live your life free from glasses and contacts, you’ve probably decided that laser eye surgery is the best option for you. Knowing which procedure is the best for you can be a bit more difficult. Those who have chosen laser eye surgery find themselves weighing the three best options: SMILE, LASIK or PRK Surgery.
All three surgeries are trusted, safe, and effective ways to correct your vision. But which procedure is best?




PRK is considered by many to be the first generation of laser vision correction. PRK can treat nearsightedness, farsightedness, and astigmatism.
During a PRK procedure, the outer layer of your cornea (also known as the epithelium) is gently removed using a manual instrument. Your surgeon then uses a cool excimer laser to reshape your cornea and correct your vision.

When is PRK a Good Option?

PRK is a good option for patients with thin or irregular corneas, patients who are predisposed to chronic dry eye, and patients whose jobs or lifestyles cause them to take a lot of direct contact to the eyes (Ex: Boxers and fighters).   Thin corneas, dry eye, and high-risk occupations can cause a patient to not be a suitable candidate for LASIK (but still may be a great candidate for SMILE, which we’ll get to later).

PRK Downsides

The major downside with PRK is recovery time: PRK has the longest recovery period out of all three laser eye surgeries. It takes about a week for the cells on the outer layer of your cornea to grow back. It can then take anywhere from two to six weeks for the cells to smooth and allow for clear vision.

If you were to elect to have PRK done in both eyes at once (which is an option) a patient will typically need to take a week off of work or driving.

There is also a higher chance of post-surgery discomfort when compared to SMILE or LASIK.




The majority of our new patients are most familiar with LASIK eye surgery. This is because LASIK is the most commonly performed laser eye surgery in practice today.
LASIK can treat mild to moderate nearsightedness, farsightedness, and astigmatism.
During a LASIK procedure, a small flap of corneal tissue is created using a femtosecond laser and then folded back. Your surgeon will then use an excimer laser to reshape the underlying corneal tissue in order to correct your vision.

When is LASIK a Good Option?

In order to be a good candidate for LASIK, a patient needs to have an adequate corneal thickness. Since a flap is created during this procedure, a certain amount of corneal thickness is required and those with thin or irregular corneas may be unable to receive LASIK.  Patients with thin or irregular corneas are typically better candidates for SMILE or PRK.

If a patient is predisposed to chronic dry eye symptoms, SMILE or PRK may be a better option. LASIK is known to run a higher risk for postoperative dry eye symptoms and can increase previously held chronic dry eye.

LASIK Downsides

LASIK is an extremely effective, safe, and trusted option.  Its one downside is it is a more complex procedure than its successor, SMILE, because it uses two lasers and creates a flap during surgery.  Because of this, there is a potential for flap-related complications post-surgery.

Flap-related complications include microscopic wrinkles called striae, irregular astigmatism, epithelial ingrowth, inflammation, and dry eye syndrome.  Flap-related complications are rare and your chance of encountering these complications are greatly decreased by partnering with an experienced surgeon like Dr. Jay Bansal.




SMILE laser eye surgery is the most advanced FDA approved laser vision correction procedure to date. SMILE has been in practice worldwide since 2012, and was approved for widespread use in the United States in 2016.

One-Step One-Laser Procedure

One of the main differences between SMILE and its predecessors is it is a one-laser procedure. Unlike PRK and LASIK, there is no use of an excimer laser during a SMILE procedure. Instead, your surgeon will use a femtosecond laser to cut a tiny incision in the cornea and use it to remove a small piece of corneal tissue (called a lenticule).  This reshapes the cornea and improves vision.

Less Invasive Surgery

SMILE is a less invasive laser eye surgery procedure than LASIK. During a LASIK procedure, your surgeon creates a flap that is 20mm in circumference. A PRK procedure creates an 8mm diameter surface removal.  In comparison, SMILE creates only a 3mm corneal key-hole incision.  This allows for more corneal stability post-surgery and less disturbance to corneal nerves during surgery.

Quiet, Odorless, and Blade-Free

During both LASIK and PRK, an excimer laser is used to reshape the cornea. During surgery, this laser makes a clicking sound and creates a noticeable odor. Since the excimer laser is not used during SMILE, the procedure is quiet and odorless.

No Flap-Related Complications

Because SMILE does not create a flap like LASIK, there is no risk of flap-related complications after surgery.

Safe, Accurate, and Fast Visual Recovery

Clinical trials for SMILE have found it to be just as safe and accurate as LASIK.

SMILE Downsides

The one downside to SMILE is that it is not yet available to treat farsightedness or astigmatism.  SMILE is currently only available to treat certain types of nearsightedness.

In addition, visual recovery takes a slightly longer time than compared to LASIK. With a LASIK procedure, a patient can experience instant visual recovery. SMILE’s visual recovery can take about one to two days.

Which is Right for Me?
