Core Insights - The 43rd European Society of Cataract and Refractive Surgeons (ESCRS2025) conference was held in Copenhagen, Denmark, where Professor Li Jun from Shenyang He Eye Hospital presented groundbreaking research on the correlation between different refractive groups and the vertical ciliary sulcus diameter [1][2] - The study revealed a significant nonlinear relationship between the horizontal and vertical ciliary sulcus diameter (STS) and refractive power, with distinct morphological differences in ciliary sulcus among various refractive groups [1] - Higher degrees of myopia (greater equivalent spherical power SE) correspond to more pronounced differences between vertical and horizontal ciliary sulcus diameters, which is critical for ICL (Implantable Collamer Lens) surgery [1] Company and Industry Summary - The research provides quantitative anatomical references for personalized ICL size selection, surgical planning, and complication prevention, potentially leading to the development of new ICL calculation formulas [2] - This advancement is expected to significantly reduce the incidence of secondary surgeries required due to mismatched vault heights, highlighting the research strength and clinical leadership of He Eye Hospital in the field of refractive surgery [2]
