Does SMILE eye surgery hurt?

If you’re considering vision correction surgery, you may have heard about SMILE (Small Incision Lenticule Extraction), a minimally invasive1Blum, M. et al.

One of the most common questions people ask is ‘Does SMILE eye surgery hurt?’. Let’s explore the pain aspect of SMILE eye surgery.

The Procedure Itself:

First, it’s important to understand the procedure itself. SMILE surgery is known for its minimal discomfort2Blum, M. et al. (2016a) Five-year results of small incision lenticule extraction (Relex Smile), British Journal of Ophthalmology. during and after the operation. The process involves creating a small, precise incision in the cornea to remove a lenticule of tissue, which reshapes the cornea and corrects vision problems like myopia (nearsightedness). Unlike LASIK, SMILE doesn’t require a flap to be created, reducing the likelihood of complications and discomfort.

During the Surgery:

During SMILE surgery, patients typically receive numbing eye drops to ensure they don’t feel any pain or discomfort. Most patients report feeling only mild pressure or slight sensations, but no pain. The entire procedure usually takes around 10-15 minutes per eye. 3Ekktet Chansue et al, Efficacy, predictability and safety of small incision lenticule extraction (SMILE),2, Article number 14, Published: 31 August 2015

Post-Operative Discomfort:

After SMILE surgery, some patients may experience mild discomfort. This is normal and usually temporary. Doctors may prescribe pain relievers or recommend over-the-counter artificial tears to alleviate any irritation. However, many patients find that they don’t need pain medication and that the discomfort is minimal.4Blum, M. et al. (2016a) Five-year results of small incision lenticule extraction (Relex Smile), British Journal of Ophthalmology.

Recovery Period:

The recovery period for SMILE surgery is relatively quick. Most patients can return to their normal activities within a day or two. The mild discomfort typically subsides within a few days to a week.5Ekktet Chansue et al, Efficacy, predictability and safety of small incision lenticule extraction (SMILE),2, Article number 14, Published: 31 August 2015 During the recovery process, it’s essential to follow your doctor’s post-operative care instructions carefully to ensure optimal healing.

In conclusion, while everyone’s pain tolerance and experience may vary slightly, SMILE eye surgery is generally considered to be a low-pain procedure. The combination of numbing eye drops and the minimally invasive nature of the surgery results in minimal discomfort for most patients.
