侯鈞賀 Chiun-Ho HouTaiwan Moderator Safety Guidelines and Preoperative Assessment for Refractive Surgery: Challenges in High Myopia and Corneal Risk FactorsRefractive surgery has evolved substantially over the past decade, offering increasingly precise and predictable outcomes. Yet, ensuring patient safety—particularly in individuals with high myopia or underlying corneal risk factors—remains a core responsibility in clinical decision-making. This presentation provides an updated, evidence-based overview of safety guidelines and preoperative assessment strategies essential for optimizing refractive surgery outcomes. We will begin by reviewing current standards for evaluating refractive stability, corneal biomechanics, epithelial thickness mapping, and posterior elevation indices. Special emphasis will be placed on the identification of subclinical keratoconus and forme-fruste ectasia, conditions that significantly elevate the risk of postoperative corneal ectasia. Practical screening algorithms—including integration of tomography, biomechanical testing, and individualized risk calculators—will be discussed to support accurate risk stratification. High myopia presents unique challenges, including thinner corneas, greater ablation depth requirements, and a potentially higher susceptibility to biomechanical decompensation. The talk will highlight recent data on surgical candidacy thresholds, residual stromal bed safety margins, and considerations for choosing between LASIK, PRK, SMILE, or phakic IOL implantation in this population. Case-based examples will illustrate real-world pitfalls and decision-making nuances encountered in screening high-risk patients. Finally, updated consensus recommendations and emerging technologies for improving preoperative detection and enhancing surgical safety will be summarized. By reinforcing rigorous assessment protocols and individualized risk evaluation, this presentation aims to support ophthalmologists in delivering safer, more predictable refractive surgery outcomes for patients with high myopia and complex corneal profiles.
蔡德中 Der-Chong TsaiTaiwan Moderator 豪雅光學近視控制鏡片 (Hoya MiYOSMART)為減緩兒童近視度數的進展,除了藥物、環境與行為策略,近年來還有多種光學介入方式可供選擇。 而這些光學措施主要是基於「周邊近視性離焦能抑制眼軸伸長」的實驗證據。 其中,DIMS(Defocus Incorporated Multiple Segments)鏡片為目前在臨床上研究最多的框架眼鏡技術。其核心設計為在鏡片中心光學區(直徑為9mm)的周邊,配置 396 個具有正3.5D的鏡片小區塊,形成持續性的近視性離焦刺激,以抑制眼軸增長。多項臨床研究顯示,相較於傳統單焦點眼鏡,DIMS 鏡片在減緩近視進展、控制眼軸伸長以及兒童配戴的耐受性方面均具有顯著優勢。本演講 將討論DIMS對於學齡前近視預防的可行性,並聚焦在對於DIMS反應不理想的個案處理。 卡爾蔡司成長睿鏡片 (Zeiss MyoCare)本演講為卡爾蔡司成長睿鏡片的第二部分,主要報告MyoCare與MyoCare S於歐洲與亞洲兒童族群 多中心、隨機對照臨床試驗結果, 歐洲 CEME 研究納入 234 名 6–13 歲兒童,配戴 MyoCare 一年後,相較單光眼鏡,近視度數進展減少 0.21 D、眼軸增長減少 0.14 mm,並顯著降低快速惡化者的比例(SE > −0.50D/yr:21.1% vs 39.3%)。中國 240 名兒童的雙盲隨機試驗顯示,在 12 個月與 24 個月的追蹤中,MyoCare 與 MyoCare S 均較單光眼鏡能顯著減緩眼軸延長及屈光度近視化的速度。12 個月時,MyoCare 與 MyoCare S 分別減少眼軸延長 41% 與 34%,並減緩近視進展 48% 與 45%。24 個月結果同樣顯示穩定的控制效果,眼軸延長分別減少 38% 與 28%。此外,以「Emmetropic Progression Ratio」分析,兩款鏡片皆能使眼軸生長趨近正視化發展,MyoCare 與 MyoCare S 的比率分別達 70% 與 68%。兩種設計在整體控制效果上相近,亦展現高度安全性與良好配戴順應性。綜合而言,MyoCare 與 MyoCare S鏡片具備良好視力品質,不論在亞洲或歐洲族群皆能有效減緩眼軸生長,使眼球發育更接近正視化軌跡,是目前具跨族群證據支持的近視控制鏡片解決方案。 眼科醫師在校園視力保健及公衛推廣中的角色面對近視狂潮,眼科醫師在校園視力保健與公衛推廣中扮演關鍵角色: Partner, Educator, Advisor。近視防治有兩大策略:延後近視發生(近視預防) 與 減緩進展(近視控制),其中近視控制主要在診間進行,而近視預防則必須走入校園。以宜蘭縣模式為例,由眼科醫師到園所進行散瞳驗光檢查,可達 92% 的大班幼兒篩檢率,顯示其優於學童自行就醫。散瞳驗光能找出視力正常的低度近視與近視前期,凸顯眼科專業在校園篩檢中的必要性。 眼科醫師同時是 宣傳視力保健知識的教育者,除了在校園演講推動「天天戶外 120 分鐘」、近視控制新知等實證策略、支持教師與校護成為對抗近視前線的重要夥伴。我們亦可針對近視前期兒童的家長,透過社群平台以圖像化、影音化內容,精準推廣正確近視衛教,促進高近視風險學童與家長的警覺心與配合度。此外,眼科醫師也能是 政策建言者。過去十多年來,眼科醫師持續協助衛政與教育單位制定重要政策,包括 2009 年全國天天戶外120政策、2013 年北市國小近視篩檢、2014 年宜蘭縣幼兒園到校散瞳驗光、2022 年宜蘭縣近視前期大班轉介方案,以及 2023 年宜蘭縣國小視力紀錄卡向下延伸至幼兒園。本演講將分享眼科醫師在校園視力保健與公衛推廣參與者、教育者與建言者 的三重的角色。
