When considering LASIK or SMILE for your eye condition, you need to consider the potential risks and benefits of both treatments. The SMILE procedure does not require a flap, so you don’t have to worry about water or rubbing your eyes after the procedure. It is also safe and painless, and you can shower the day after the procedure. In addition, SMILE patients can resume wearing eye make-up and participating in full contact sports within a few days.


Unlike traditional LASIK, SMILE is an outpatient procedure that leaves the corneal outer layers mostly intact, leaving the eye strong after the procedure. During the procedure, a femtosecond laser or excimer laser is used, which results in less disruption to the eye structure. Because SMILE does not create a flap, patients do not need to wear contact lenses or other lenses during surgery.

SMILE is a one-step laser eye surgery that uses a femtosecond laser to create a thin layer beneath the surface of the eye. The procedure is virtually silent and odour-free, and requires a tiny incision on the eye’s surface. Unlike LASIK, the incision made during SMILE is usually no larger than four millimeters. SMILE also has less risk of side effects, because the upper layers of the cornea are untouched by the laser.


Although the two procedures are similar, SMILE is different from LASIK in a number of ways. For one thing, SMILE uses a smaller incision, which requires less healing time than LASIK. This means less chance of complications. Another difference between SMILE and LASIK is the type of corneal flap created. SMILE uses a laser to create a pocket of tissue that surrounds the incision, while LASIK creates a 300 degree circular flap.

The SMILE procedure uses a Carl Zeiss VisuMax laser, which is the only femtosecond laser with precision and the lowest increase in eye pressure. This means that SMILE patients experience no pain during the procedure. Unlike LASIK, SMILE also doesn’t require the patient to wear contact lenses after surgery. SMILE is ideal for people with active lifestyles, such as sports enthusiasts, or who work in environments where they need to keep their eyes open for long periods of time.


Despite the similarities between LASIK and SMILE, there are some differences between the two refractive procedures. For example, LASIK can be repeated as needed if your refractive errors change, whereas SMILE can only be done once. Nevertheless, both procedures can improve vision and offer similar safety and results.

Compared to LASIK, SMILE has a lower risk and recovery time. Additionally, it requires a smaller incision than LASIK. SMILE also does not require a flap, which reduces the risk of corneal dislocation. This means that SMILE is preferred by athletes, military service members, and people with an active lifestyle.

Despite the differences between the two procedures, LASIK is the more popular procedure worldwide. It is also more effective in treating a full range of eye prescriptions. Smile, on the other hand, has limited success in treating night vision problems. In addition, SMILE is not very effective in treating higher-order aberrations. Although SMILE requires less surface damage, it is still associated with a high risk of refractive errors.

SMILE vs LASIK results

The Smile procedure is an alternative to LASIK and has several advantages. LASIK has been the gold standard for vision correction for years, but newer laser eye surgery methods like SMILE are gaining popularity. These newer procedures offer different benefits, as well as different risks.

SMILE has the advantage of delivering better early visual recovery than LASIK. However, it does not work as quickly as LASIK. It also takes about one to two days for the SMILE flap to form properly. In addition, LASIK patients can see the results almost immediately.

This study compared the OSI scores of the two groups using SPSS 18.0 statistical software. Results from the SMILE group were significantly better than those from the FS-LASIK group. SMILE patients also reported fewer subjective symptoms. However, the results were not statistically significant.


ReLEx SMILE LASIKS are a minimally invasive form of LASIK that preserves the cornea’s upper layer. This procedure eliminates the need for a flap and minimizes post-operative discomfort and visual complaints. Patients will enjoy fast visual recovery. There is minimal downtime following the procedure, and patients can return to their normal activities within a day. The procedure is very safe and does not involve tissue ablation.

The ReLEx SMILE procedure involves making a tiny incision in the cornea. The ophthalmologist will then remove the lenticule through this incision. Most patients will experience some hazy vision for one to two days following surgery, but this will wear off over time. Patients are generally able to drive after the procedure, though they should avoid using certain devices for the first two or three days. Although the procedure is safe, the long-term success rate is still unknown.
