EYEREUM EYE CLINIC performed the first SMILE pro surgery in Korea. (on August 14, 2023, by Dr. David S.Y. Kang)
We are a specialized EYE CLINIC for Low Energy_SMILE Surgery. Low Energy SMILE surgery using VISUMAX 800 aims to improve the quality of vision after surgery.
VISUMAX800 represents the latest generation of ZEISS femtosecond lasers, offering reduced laser time in comparison to its predecessors while making tissue separation with SMILE pro from ZEISS easier than before. A shorter suction time can increase patient comfort and reduce stress for patients during the laser treatment.
'Low Energy SMILE' of EYEREUM Eye Clinic is recognized as a global standard and also as a revolutionary innovation in ReLEx SMILE surgery that simultaneously corrects myopia and astigmatism. By minimizing the corneal incision to 1/10th of the level of LASIK, Low Energy SMILE leads to less damage to the surgical site and cornea, as well as quick visual recovery. Low Energy SMILE, this innovative surgical procedure makes better quality of vision.

SMILE
Produce rough lenticule using high energy
(Dr. David Donate, Rozenn Thaëron, ZEISS European Refractive Laser Symposium, 31 May 2015.)
In SMILE procedures, a lenticule is created inside the intact cornea, using high energy exposure, which creates a rough surfaced lenticule.

Creates a smooth lenticule using low energy

Whereas in Low Energy ReLEx SMILE, the amount of energy is low, producing a smoother lenticule and causing less damage to the cornea.

After a standard SMILE LASIK, patients usually complain about 2~3 weeks of continual vision opacity and a slow recovery. However, with Low Energy ReLEx SMILE, 91% of patients are amazed at achieving a 20/20 vision the following day.
In Low Energy ReLEx SMILE, HOAs and Coma which are causes of blurred vision, are produced far less.

During Low Energy ReLEx SMILE, threshold energy is the minimum energy required to produce a lenticule For this reason it is important to find the safe level threshold energy.
EYEREUM recommends LOW Energy ReLEx SMILE and verifies how much the energy level is close to the plasma threshold ,which has changed after surgery.
