Let’s explore the surgery duration of SMILE LASIK and its differences from LASIK.
Modern Concerns When Considering Vision Correction Surgery
As the population dependent on glasses and contact lenses due to vision deterioration increases, these assistive devices have become daily necessities. Particularly during summer water activities, glasses and lenses act as significant constraints. Consequently, many people plan vision correction surgery during vacation or school break periods, but deciding between LASIK and SMILE LASIK can be challenging. In this article, we will explain in detail the key differences between these two surgical methods.
Two Surgical Methods Distinguished by Corneal Flap Presence
The fundamental difference between the two surgeries lies in the corneal flap formation method. In the case of LASIK, a flap is created on the corneal surface and lifted, then a laser is applied to the inner stromal layer to correct refractive errors. After completing laser irradiation according to the correction amount, the flap is repositioned to complete the surgery.
On the other hand, SMILE LASIK is an abbreviation for Small Incision Lenticule Extraction, performed through a minimal incision of approximately 2mm. The laser passes through the corneal surface layer and irradiates the inner stromal layer according to the correction range, then the corrected tissue is separated and removed through the small incision site. In summary, while LASIK forms a flap, SMILE LASIK is a surgical technique that enables vision improvement without a flap.
Benefits and Considerations of LASIK Surgery
Each surgical method has its own advantages and disadvantages. In the case of LASIK, the structure of replacing the flap results in relatively low pain levels and fast recovery speed, making it suitable for those who need to quickly return to work or studies. From an economic perspective, it also has the advantage of being less burdensome compared to other surgical methods.
However, there are points to note. Since the flap uses natural adhesion rather than suturing, the possibility of flap displacement due to external impact after SMILE LASIK surgery time cannot be ruled out. Additionally, there is a relatively high probability of dry eye symptoms occurring due to damage to tear gland nerves during the flap formation and stromal irradiation stages.
Characteristics and Precautions of SMILE LASIK Surgery
SMILE LASIK is characterized by a minimal incision of approximately 2mm, which shortens the SMILE LASIK surgery time. The range of corneal damage is limited and nerve damage is minimized, resulting in a low possibility of dry eye occurrence. Thanks to the structure that does not create a flap, there is less discomfort and smooth recovery, with the advantage that high-intensity physical activities such as martial arts are possible after surgery. Due to these characteristics, SMILE LASIK surgery time is recommended for office workers or students who need a quick return to daily life.
However, in terms of cost, it is higher than other surgical methods. The correction range is also limited to within -10 diopters for myopia and -5 diopters for astigmatism, so it may be difficult to apply for those with extremely high myopia or astigmatism. Therefore, it is essential to confirm SMILE LASIK applicability through precise preliminary examination.
Suitable Candidates by Surgical Method
LASIK is suitable for those who want fast recovery similar to SMILE LASIK surgery time while reducing economic burden. On the other hand, SMILE LASIK is recommended for those who anticipate vigorous activities after surgery or want to minimize dry eye symptoms. However, individual corneal thickness, degree of refractive error, lifestyle patterns, etc., must be comprehensively considered.
Essential Considerations When Choosing Vision Correction Surgery
Whether choosing SMILE LASIK or any other vision correction surgery, the most important thing is to decide on a surgical method suitable for you based on detailed examination and accurate diagnosis. Before surgery, it is essential to comprehensively evaluate corneal thickness, shape, presence of abnormalities, etc., through precise examination to confirm whether the eye condition is suitable for SMILE LASIK. It is not advisable to decide on surgery without sufficient examination, and please make a careful decision through adequate consultation with a specialist.
