With the development of medical technology, the types of vision correction have diversified. Typical eye correction procedures include LASIK and LASEK. LASIK and LASEK show differences in the range of refractive abnormalities, surgical methods, and clinical characteristics. LASIK is a method of separating the corneal layer, shaving the inside of the cornea, and covering the lid. Compared to Lasek, there is little pain after surgery and the recovery speed is fast, but it is not appropriate for occupations with a lot of activity because they are weak against external shocks.
LASEK is a method of correcting vision by cutting the corneal surface at once. Since there is no process of separating the corneal layer, surgery is simple and complications are low, and although it is resistant to external shocks, recovery is relatively slow, intensive management is required for three to six months.
Smile LASIK is considered a next-generation vision correction that combines the advantages of LASEK and LASEK. Unlike LASIK or LASEK, which cuts the cornea with an excimer laser, it is a method of using an ultra-precision femtosecond laser. The risk of corneal damage can be minimized because the corneal incision is not made during the surgery and the corneal incision is made to a minimum to irradiate the corneal parenchyma only. This greatly reduced nerve damage, significantly reducing the risk of side effects such as dry eye, corneal opacity, and conical corneal disease.
The safety of the surgery was confirmed by a domestic research team, and in the Smile Lasik 100,000 cases, including moderate and high myopia, announced at the 40th European Society for Erectomy (2022 ESCRS, Milan, Italy) held in October this year, only 0.4% of the 100,000 Smile Lasik surgeries were reported.
It is clear that Smile LASIK is a surgery that has many advantages in safety, postoperative aftereffects, and recovery period compared to conventional vision correction However, since not everyone can receive a smile LASIK, it is desirable to thoroughly examine various parts such as pupil size, corneal thickness, endothelial cells, and intraocular pressure in advance to find the most appropriate vision correction. In addition, when selecting hospitals and medical staff, it is necessary to check whether they are hospitals with the latest equipment and inspection systems, whether they have extensive clinical experience, and whether the post-mortem system is well established to increase surgical stability and satisfaction. Whether the medical staff is able to investigate the laser at the optimal location can be determined by whether they have "Smile Doctor Certification." Smile Doctor Certification is an official certificate given to medical staff with abundant surgical experience and high understanding of equipment by Carl Zeiss, Germany, which developed Smile Lasik.
