Abstract

Objectives: Scleral lenses (SLs) represent a key treatment for visual rehabilitation in patients with irregular corneas, such as keratoconus (KC), pellucid marginal degeneration (PMD), and postlaser in situ keratomileusis (LASIK) ectasia. This study evaluates the impact of profilometry-guided SLs on visual acuity (VA) and ocular aberrations in these patients.

Methods: Medical records of 23 eyes from 23 patients with KC, PMD, and post-LASIK ectasia were reviewed. All patients were fitted with profilometry-guided SLs. High-contrast visual acuity (HCVA), low-contrast visual acuity (LCVA), and aberrometry parameters (Strehl ratio, higher-order root mean square (HO-RMS), coma, spherical aberration, and trefoil) were analyzed before and during SL wear.

Results: HCVA improved significantly from 0.62±0.09 logMAR at baseline to 0.03±0.01 logMAR with SL wear ( P <0.05). LCVA also showed significant improvements ( P <0.05). HO-RMS decreased from 2.70±0.54 D to 1.00±0.20 D ( P <0.05), with notable reductions in coma (1.31±0.21 D to 0.49±0.04 D) and trefoil (1.26±0.29 D to 0.34±0.09 D).

Conclusions: Profilometry-guided SLs significantly improve VA and reduce higher-order aberrations in patients with irregular corneas, offering an effective nonsurgical solution for enhancing vision quality in these complex cases.

轮廓测量引导巩膜晶体改善视力和减少不规则角膜的眼像差：回顾性病例系列。

目的：巩膜晶状体（SLs）是不规则角膜患者视力康复的关键治疗方法，如圆锥角膜（KC）、透明边缘变性（PMD）和激光原位角膜磨除术（LASIK）扩张。本研究评估了轮廓测量引导的SLs对这些患者的视力（VA）和眼像差的影响。方法：回顾性分析23例KC、PMD、lasik术后扩张患者23只眼的临床资料。所有患者均安装了轮廓线引导的SLs。高对比视力（HCVA）、低对比视力（LCVA）和像差测量参数（Strehl比、高阶均方根（HO-RMS）、彗差、球差和三叶草）在SL磨损前和磨损过程中进行分析。结果：佩戴SLs后，HCVA从基线时的0.62±0.09 logMAR显著改善至0.03±0.01 logMAR。结论：轮廓仪引导的SLs可显著改善不规则角膜患者的VA，降低高阶像差，为提高这些复杂病例的视力质量提供了一种有效的非手术解决方案。

期刊介绍： Eye & Contact Lens: Science and Clinical Practice is the official journal of the Contact Lens Association of Ophthalmologists (CLAO), an international educational association for anterior segment research and clinical practice of interest to ophthalmologists, optometrists, and other vision care providers and researchers. Focusing especially on contact lenses, it also covers dry eye disease, MGD, infections, toxicity of drops and contact lens care solutions, topography, cornea surgery and post-operative care, optics, refractive surgery and corneal stability (eg, UV cross-linking). Peer-reviewed and published six times annually, it is a highly respected scientific journal in its field.
