Are you considering laser eye surgery but are unsure of which option is best for you? If you have done any research, you will have noticed that PRK, LASIK and SMILE are some of the most common options.
But what are the pros and cons of each? What recovery time and side effects are there? And how can you make an informed decision?
If you are asking any of these questions, you are not alone, and rest assured that we have you covered. Here’s everything you need to know.

How LASIK Surgery Works
Laser assisted in situ keratomileusis, or LASIK surgery, was approved for use in the 1990s and represented a significant development in laser eye treatment. Remaining one of the most popular treatment options, many patients enjoy fast recovery times compared to other methods.
Once the eye has been numbed with drops, treatment begins. The process involves creating a thin circular flap in the cornea which is then peeled back to reveal the corneal stroma. Once exposed, a laser is used to reshape it to correct refractive errors.
After correction, the flap is cleansed and put back in place. The edges fuse back to the rest of the epithelium without the need for stitches.
How PRK Surgery Works
Photorefractive keratomileusis, or PRK surgery, is one of the oldest yet most invasive laser eye surgeries. Unlike treatment options, the cornea is not cut, making it an ideal option if you have a thin or scarred cornea.
As treatment commences, eye drops are provided to numb the area. Once these have taken effect, your healthcare provider will remove the corneal epithelium to provide deeper access to the cornea.
Once exposed, a laser is used to fix any irregularities before a soft contact lens is applied to kickstart the healing process. Over the next three to five days, a new corneal epithelium will grow back, protecting the cornea once more.
How SMILE Surgery Works
Small incision lenticule extraction, or SMILE surgery, is one of the newest forms of laser eye surgery available. It’s the least invasive treatment option, restoring near-sightedness and astigmatism without the need for the corneal epithelium to be peeled back or removed.
Often likened to keyhole surgery, SMILE involves creating a small incision on the surface of the eye following the application of drops to numb the eye. A laser is used to deliver small pulses, outlining the tissue that needs to be removed.
Once identified, the laser is then used to create a tunnel for your surgeon to access and remove the corneal tissue.
Comparing Recovery Times and Side Effects
When choosing the best treatment option for you, it’s important to consider the recovery times and potential side effects of each. Let’s break it down.
Recovery Times
LASIK
When it comes to fast results, LASIK takes the crown. The majority of patients report a significant improvement in their vision within a day of surgery. You will experience a day or two of blurry vision and dry eyes but will commonly be able to resume normal activities within a few days.
PRK
PRK surgery offers the slowest recovery time of the laser eye treatment options. As a result of the corneal epithelium needing to grow back the initial recovery period can take up to a week and, in most cases you won’t be able to return to normal daily activities for up to three weeks post treatment.
SMILE
For the majority of patients, SMILE offers the quickest recovery time of all laser eye treatments. As the corneal epithelium remains uncut and in place, you are able to return to your normal daily activities within just a few days.
Side Effects
LASIK
The side effects commonly associated with LASIK surgery are dry eyes and night vision disturbances. These are usually mild and resolve over time. If you struggle with dry eyes, it can last for up to 6 months but will be managed by your healthcare provider.
PRK
After PRK surgery, some people experience glares or halos especially at night, blurry and double vision. These commonly resolve shortly after your eyes are healed.
SMILE
Side effects of SMILE surgery are generally milder than other laser eye treatments which is why it’s a popular choice. You may experience some mild dryness or light sensitivity, but these too will resolve quickly once you have recovered from surgery.
Ideal Candidates for Each Procedure
The ideal candidate for each procedure is dependent on their needs, goals, budget and lifestyle. Aside from being of an age where their vision has stopped developing, the ideal candidate for each treatment has the following qualities.
LASIK
- Those with healthy, thick corneas
- Mild to moderate refractive errors
PRK
- Those with thin or scarred corneas
- Those with a stable prescription
SMILE
- Those who have mild near-sightedness or astigmatism
- Those who are seeking a quick recovery
Making an Informed Decision with Your Surgeon
As with any treatment, the best option is dependent on your unique needs so it’s important to make an informed decision with your surgeon. During consultations, you should consider:
- The current condition of your eyes.
- Your goals for treatment.
- The budget that you have.
- The potential risks of treatment.
- The time that you can commit to recovery.
- The knowledge and experience of the surgeon.
It is also a great time to raise any concerns or queries that you have. Although an increasingly popular treatment option, it’s natural to feel anxious about surgery. Your healthcare professional can help to put your mind at rest so you can make the best decision for your needs.
