咁激光唔介紹用 都可以講解下嗎
矯視手術其實有好多種，早期有RK，有LASEK，LASIK，到近來嘅SMILE
略略講就係愈新嘅procedure愈低侵入性，如果就咁比嘅話當然SMILE會最好，因為最低侵入性。佢同LASIK嘅分別主要係唔會製造個瓣(flap)出嚟，開刀範圍細好多，理論上會少啲併發症(當然根據evidence based medicine要真係做研究先可以肯定)
有唔少study 做左，LASIK 同SMILE outcomes 係comparable, 但SMILE做完之後 dryness 同corneal nerve sensitivity 都好d。第二份paper 的conclusion 係 SMILE induces less keratocyte apoptosis, proliferation and inflammation compared with femtosecond laser LASIK.
