Hello, this is Goyang Shinsegae Eye Clinic.
If you are in your 20s or 30s and considering vision correction surgery, you may wonder whether LASIK or LASEK would be more suitable for you.
People with busy schedules, such as office workers and university students, often consider recovery time, postoperative discomfort, and how soon they can return to their daily activities.
In recent years, various types of advanced equipment and procedures have been introduced to improve the surgical and recovery processes associated with conventional LASEK, providing patients with a broader range of options.
Today, we will examine the differences between LASIK and LASEK and discuss the features of the AMARIS RED laser system.


SMILE LASIK vs. 2-Day LASEK
✔ Amount of Corneal Tissue Removed and Risk of Glare
2-Day LASEK preserves more of the cornea’s structural support. This may reduce the risk of secondary complications such as corneal ectasia, which can occur when the cornea becomes excessively thin and weakened.
SMILE LASIK, on the other hand, may leave less structural support than LASEK, potentially resulting in a comparatively greater risk.
*Corneal ectasia: A complication in which a weakened area of the cornea gradually protrudes after LASIK or SMILE surgery.
✔ Intraoperative Stability and Decentration
LASIK, SMILE, and LASEK procedures require accurate treatment of an optical zone approximately 6 mm in diameter at the center of the cornea.
However, patients may make small movements during the procedure because of tension or nervousness, making it difficult to target the intended treatment zone without assistance.
For this reason, excimer laser systems are equipped with eye-tracking technology. The system monitors eye movements and helps the laser remain aligned with the center of the cornea during treatment.
SMILE LASIK does not use the same type of active eye-tracking system during laser application. Instead, the eye is held in place using suction. If the patient moves their eye or becomes tense, the suction may be interrupted—a situation known as “suction loss.”
Some reports indicate that suction loss may occur in approximately four out of every 100 patients.
In 2-Day LASEK, the treatment process is performed under laser control. During SMILE LASIK, however, the lenticule must be manually separated and removed. This step may carry additional procedural risks, such as irregular tearing of the corneal tissue or epithelial ingrowth within the corneal stroma.

✅ Astigmatism Correction
2-Day LASEK may be considered for patients with high myopia or high astigmatism. With SMILE LASIK, however, the predictability of astigmatism correction may become more limited when astigmatism exceeds −2.00 D.
✅ Postoperative Glare and Halos
With 2-Day LASEK, the optical zone can be adjusted more flexibly. SMILE LASIK may offer less flexibility in optical-zone adjustment, potentially increasing the likelihood of postoperative glare or halos in some patients.
✅ Cost of Surgery
2-Day LASEK generally costs slightly over KRW 1 million, whereas SMILE LASIK may cost between KRW 2 million and KRW 4 million.
One reason for the higher cost of SMILE LASIK is the use of a disposable suction interface. Depending on the equipment, this single-use component alone may cost approximately KRW 1 million to KRW 3 million, which is reflected in the overall surgical fee.
Would you rather save KRW 2 million on your procedure and use that money for a four-day, three-night trip abroad?
Because 2-Day LASEK does not require similarly expensive disposable components, it may be a more economical option.

What Is AMARIS RED?
AMARIS RED is an excimer laser system used for LASEK and other laser vision correction procedures.
It is designed to enhance precision through accurate laser delivery and real-time eye-tracking technology.
The system can analyze the curvature of the cornea in detail and adjust the depth of laser ablation during the procedure.
Its high-speed eye-tracking system also detects eye movements while the laser is being applied.
Many people searching for a recommended eye clinic in Ilsan are interested in advanced systems such as AMARIS RED because they are designed to support precise, individualized vision correction.


How Is It Different from Conventional LASEK?
Conventional LASEK may involve removing the corneal epithelium with alcohol or a brush before applying the laser.
In contrast, all-laser LASEK performed with AMARIS RED uses a laser throughout the treatment process.
This approach was developed to reduce direct mechanical contact with the cornea. However, its suitability may vary depending on each patient’s eye condition.
When searching for a recommended eye clinic in Ilsan, it is important to consider more than the equipment alone. A comprehensive examination and consultation are necessary to determine which vision correction method is appropriate for your eyes.

How Long Is the Recovery Period?
Recovery time can vary depending on the patient’s eye condition, general health, and individual healing response.
After a procedure performed with AMARIS RED, many patients can generally resume basic daily activities within two to three days.
When choosing an eye clinic in Ilsan, however, it is advisable to consider not only the expected recovery period but also whether the procedure is appropriate for your eyes based on a detailed examination and consultation.
People in their 20s and 30s often lead busy lives filled with university studies, job preparation, and work responsibilities. For this reason, recovery time and the expected return to daily activities are major considerations when choosing vision correction surgery.
However, neither LASIK nor LASEK can be considered universally superior. Corneal thickness, overall eye health, refractive error, and lifestyle should all be evaluated before selecting a procedure.
AMARIS RED is a laser system equipped with precision treatment technology and eye-tracking features. Whether it is suitable for a particular patient depends on their eye condition and examination results.
If you are considering vision correction surgery, undergo a comprehensive eye examination and detailed consultation to determine the most appropriate option for your individual needs.
Thank you.
