This case reports on the use of wavefront-guided (wfg) optics on custom ocular impression-based scleral lenses (IBSLs) for visual improvement in a patient with keratoconus (KC). A 28-year-old man with KC, who had previously failed a traditional, diagnostically fit scleral lens (tSL), was fit with IBSLs with traditional optics. Using a system that included a dot matrix on the IBSL and a wavefront aberrometer with pupil and dot registration software, a wfgIBSL was created. When compared with the IBSL, the wfgIBSL reduced the total higher-order root mean square (HORMS) 67% and 64% in the right and left eye, respectively, resulting in a 2-line improvement in best-contact lens visual acuity (BCLVA) for both eyes. This case demonstrates the successful creation and application of a wfgIBSL resulting in a stable lens, a reduction in HORMS, and an improvement in BCLVA, after failure with a diagnostically fit tSL.
本病例报告了在角膜地形图引导（wfg）光学设计下，使用基于定制巩膜接触镜印模（IBSL）的方法，为圆锥角膜（KC）患者改善视力的情况。一位 28 岁男性患者，曾患有 KC，且传统的诊断适配型巩膜镜（tSL）治疗失败，随后接受了传统光学设计的 IBSL 治疗。通过使用一种包括 IBSL 上的点矩阵和具有瞳孔及点注册软件的波前像差仪的系统，我们创建了 wfgIBSL。与 IBSL 相比，wfgIBSL 使右眼和左眼的总高阶均方根（HORMS）分别降低了 67%和 64%，双眼最佳矫正视力（BCLVA）提高了 2 行。本病例成功地展示了 wfgIBSL 的创建和应用，在传统的诊断适配型 tSL 治疗失败后，wfgIBSL 可以产生稳定的镜片，降低 HORMS，并提高 BCLVA。
