Kreatorefractive Lenticular Extraction (KLEX) 2024 : Personal Experience of Plasma SMILE

Since the introduction of Small Incision Lenticule Extraction (SMILE) over a decade ago by a single manufacturer, the market has expanded to include various laser platforms capable of performing KLEX. While these platforms share similarities, they also exhibit significant differences in hardware delivery methods, the configuration of pulse placement, lenticular geometry and systems for its key distinctions relevant to both physicians and patients.

Manufacturers often cite laser speed in MHz, claiming higher speeds are always better. However, surgeons often confuse the maximum achievable laser frequency with the actual repetition rate. The actual time required to deliver the laser to the patient. The rate-limiting step is primarily the beam scanners that direct the laser pulses. Different systems feature varying numerical apertures (NA) and focal spot sizes, which in turn affect the laser's peak intensity. These factors contribute to the quality of the lenticule. Instead, comparisons should consider the actual total time for lenticule formation.

Laser delivery methods vary, with some systems using high pulse energy and low spot density to facilitate dissection, albeit with higher risk of OBL. Others utilize low pulse energy and tight spot/track placements at low to moderate speeds to achieve smoother dissection surfaces. During light-induced optical breakdown, the laser creates a plasma state, vaporizing tissue and forming H2O and CO2. Plasma SMILE is a technique that utilizes low pulse energy, which not only reduces pulse energy but also results in smoother surfaces and easier lenticule separations.

Plasma SMILE demonstrates clinical outcomes comparable to traditional SMILE, with potentially improved corneal HOAs.

강성용 원장이 강연한 '플라즈마 스마일(Plasma SMILE)'은, 스마일(SMILE) 수술 후 시력의 질을 높이기 위해 고안한 수술법입니다. 

스마일수술 시 LIOB(Laser induced optical breakdown) 동안 초기 플라즈마 만을 만들 수 있는 적당량의 레이저 에너지만을 사용해 각막 렌티큘을 만드는 것이 핵심입니다.

또한 레이저의 스팟/트랙 간격을 조정해 총 에너지 용량을 일정하게 유지하면, 수술 시 각막 내 가스기포(OBL) 발생을 최소화하고 고위수차 발생량을 획기적으로 감소하는 결과를 보입니다. 

스마일라식은 빠른 물리적 회복과, 근시, 난시 교정에 우수하나,야간 빛 번짐의 원인이 되는 고위수차의 발현을 해결하는 것이 안과 학계의 오랜 과제였습니다. 

그런 의미에서 이번 강성용원장의 발표는 스마일라식 후 각막 고위수차 발생을 획기적으로 줄일 수 있는 해법으로서 학술적 가치가 크다는 평가를 받았습니다.
