SMILE PRO vs SMILE LASIK: What’s the Difference?Vision correction technology has been advancing rapidly in recent years. SMILE LASIK emerged as an evolution of traditional LASIK and LASEK, and now, an upgraded version called SMILE PRO has been introduced, leading many to wonder about the differences between the two. However, just because a procedure uses newer equipment doesn’t automatically mean it’s better.Both surgeries are known for their excellent safety profiles and high precision, but they each have distinct advantages. That’s why it's important to choose the procedure that best suits your eye condition, based on accurate information.What is SMILE LASIK?SMILE LASIK differs from traditional LASIK or LASEK in that it doesn’t involve creating a corneal flap. Instead, it corrects vision by using a small 2–4 mm incision to remove a thin lenticule formed within the cornea. Since the incision is smaller, recovery is faster, pain is minimized, and the structural stability of the cornea is better preserved. For these reasons, SMILE LASIK is considered a procedure that overcomes the drawbacks of LASIK and LASEK.What is SMILE PRO?SMILE PRO is an upgraded version of SMILE LASIK that utilizes the latest technology from ZEISS—the VISUMAX 800—to achieve higher precision and speed. One of the most significant differences lies in the laser speed. While SMILE LASIK uses a 500kHz laser, SMILE PRO operates at 2MHz—almost four times faster.This results in a much shorter laser application time, reducing the entire procedure to under 10 seconds. That means fewer variables like patient anxiety or eye movement can affect the outcome. Another key advancement is in eye centration. Previous SMILE procedures required manual alignment, which could limit the precision of astigmatism correction.SMILE PRO, however, is equipped with CentraLign and OcuLign—automated centration alignment features that recognize the visual axis and even compensate for slight eye rotation when the patient lies on the surgical bed. Thanks to this technology, more accurate outcomes can be expected in complex cases like high astigmatism, compound astigmatism, or hyperopic astigmatism.Does that make SMILE LASIK a lesser option?Not at all. SMILE LASIK has already proven its safety and predictability through extensive clinical results and remains a standard procedure for correcting myopia and moderate astigmatism.From a medical standpoint, understanding the strengths of both SMILE LASIK and SMILE PRO is crucial to choosing the best procedure for each patient.For example, a patient in their 20s with good corneal health and a moderate prescription can expect excellent results with SMILE LASIK alone. Conversely, if a patient has high astigmatism, asymmetric corneal alignment, or needs fast recovery and precise correction—perhaps due to their occupation—SMILE PRO may be more suitable.Beyond cost and equipment: what’s best for you?Even if the surgical techniques seem similar, differences in technology can affect surgical efficiency and patient comfort during the procedure.SMILE PRO, being built on cutting-edge equipment, tends to be more expensive than SMILE LASIK.But what matters most is not just the price—it’s about identifying the surgerythat matches your eye condition, desired recovery speed, and lifestyle.In the end, SMILE and SMILE PRO aren’t necessarily better or worse than each other—they are distinct options that should be selected based on the patient’s eye characteristics, daily life, and degree of correction needed.Your doctor must consider more than just the surgical equipment—they should evaluate the corneal thickness, curvature, tear film, retina, and optic nerve through comprehensive tests to determine the safest and most effective method.Vision correction is a one-time procedure that can impact your eyesight for life. That’s why it’s crucial to make an informed decision through thorough testing and consultation. While technology keeps advancing, it’s the responsibility of the medical team to apply it precisely to each patient.Whether you choose SMILE or SMILE PRO, BGN Eye Clinic Jamsil strives to understand your eyes and lifestyle in the most personalized way. If you’re looking for a high-quality surgery backed by the expertise and skill developed through over 100,000 procedures, we invite you to visit BGN Eye Clinic for a consultation.

LASIK vs. LASEK: Which Surgery Is Right for Me?When considering vision correction surgery, LASIK and LASEK are among the most commonly known procedures. Since their names are similar and both involve the use of lasers, many people often confuse the two.However, the surgical techniques, recovery processes, and suitability for different eye conditions differ significantly. Today, we’ll explain the exact differences between LASIK and LASEK, and who may be better suited for each type of surgery.Differences Between LASIK and LASEKLASIK surgery involves creating a thin corneal flap, reshaping the underlying corneal tissue with a laser, and then repositioning the flap.LASEK, on the other hand, removes the corneal epithelium (the outer layer), reshapes the tissue underneath using a laser, and then places a protective lens over the eye to support healing.Because of the different techniques, there are distinctions in terms of recovery speed, pain level, and impact on the cornea.Generally, LASIK causes less pain and offers quicker recovery, often allowing patients to return to daily life the very next day. In contrast, LASEK can involve a few days of discomfort during epithelial regeneration, and it may take longer for vision to stabilize.However, since LASEK doesn’t involve creating a corneal flap, it offers higher stability against external trauma. LASIK, which requires flap creation, needs a certain amount of corneal thickness, while LASEK can be performed even on thinner corneas.Who Is Better Suited for LASIK?Because LASIK allows for fast recovery and causes less discomfort after surgery, it’s a great option for working professionals or students who need a quick return to daily life.It’s also a good choice for those who are sensitive to pain or feel burdened by several days of post-surgery discomfort. However, it’s important that candidates for LASIK have sufficient corneal thickness and are not frequently exposed to external impact in their daily lives.Who Is Better Suited for LASEK?Since LASEK doesn’t involve making a flap and only removes the epithelial layer, it can be suitable for patients with thin corneas who are not eligible for LASIK. People who frequently engage in high-impact sports like martial arts or swimming, or who are regularly exposed to external trauma, may find LASEK a safer choice.LASEK is also recommended for those requiring more precise correction, such as individuals with high myopia or astigmatism. In fact, some patients opt for LASEK even if they are eligible for LASIK, preferring the enhanced safety and outcomes despite a longer and more uncomfortable recovery.So Which Surgery Is Better?Many people ask whether LASIK or LASEK is better, but it's not a matter of one being superior to the other. The best procedure depends on many factors—corneal thickness, dry eye condition, job type, daily environment, and personal hobbies.The best approach is to undergo a detailed eye examination and consult with an ophthalmologist to determine the most suitable vision correction method for you.Since everyone’s eyes are different, the priority is to find the procedure that fits your unique needs. That begins with a comprehensive diagnostic process.Vision correction surgery is more than just improving how well you see—it’s a key decision that affects your overall quality of life.No matter which surgery you consider, the most important thing is to receive an accurate diagnosis, understand the surgical methods available, and confirm which approach best suits you.If you're unsure, don’t hesitate to speak with a trusted eye care professional and find the correction method that’s right for you.
