厚镜片带来的负担、运动时的诸多限制——高度近视患者的日常常面临不便。全光塑作为一种个性化屈光手术，根据高度近视人群的眼部特点设计，为近视矫正手术提供了一种新的方向。

全光塑在术前通过相关设备采集眼部数据。它会采集角膜地形图、瞳孔直径、眼轴长等数据。这些数据能反映个人眼光学系统的差异，为手术方案提供依据。1

该术式的特点在于切削方案的规划。采集到的数据会通过光线追踪（Ray Tracing）算法模拟约2000道光线4，转化为专属的3D眼模型。并基于模型并模拟伤口愈合和生物力学效应7,8，规划定制属于你的角膜表面轮廓——通过改变角膜表面轮廓进而矫正视力1-5。此外，全光塑在设计中考虑高阶像差问题，且设计不增加术后高阶像差6,7,9,13*??§。

一项与全光塑术式相关的真实世界临床研究显示（n=400眼），术后三个月，超过50%视力达到1.5及以上，89.3%达到1.2及以上，100%达到1.0及以上9。多数接受近视激光手术的患者，近视激光手术术后视力一般24小时可恢复10。

当然，该术式也有明确的适配门槛：全光塑的适应症为1100度以下近视和450度以下散光。患者需年满18岁、屈光状态稳定2年以上，且需通过术前全面检查，排除圆锥角膜、重度干眼等禁忌症。术前检查是医生优化方案的重要依据，能让方案更贴合个人眼部条件。1,11,12,14,15

如果希望摆脱厚重镜片的束缚，全光塑这款近视激光矫正手术可以作为一个了解的方向。它利用相关技术辅助方案设计，为近视人群提供了一种可能。2,7

§In 6.0 mm pupils, mean ± SD spherical aberration decreased by 0.07μm after wavelight plus (0.13 ± 0.10 preop; 0.06 ± 0.12 at 3 months postop) and increased by 0.06μm after wavefront-optimized treatment (0.12 ± 0.10 pre-op; 0.18 ± 0.12 at 3 months postop); p<0,001 for wavelight plus vs. wavefront-optimized.

声明：近视矫正属医疗行为，患者存在个体差异，术后效果因人而异，患者需在专业临床机构的临床医师的指导下进行。
