Abstract

Background: To establish normative values for stromal curvature and its relationships to anterior and posterior curvature.

Methods: Retrospective observational study. Data were obtained from 75 eyes of cataract surgery patients using a high-resolution anterior segment optical coherence tomograph (AS-OCT; MS-39, CSO). Data analysis included anterior, stromal, and posterior curvature across multiple zones (1.0-5.0 mm), and derived curvature ratios.

Results: The anterior-to-stromal curvature ratio (ASR) remained stable (1.016-1.007), while the stromal-to-posterior (SPR) and anterior-to-posterior (APR) ratios exhibited trends of slight change (SPR: 1.149-1.167; APR: 1.167-1.175). The refractive power analysis revealed incremental effects across one, two, and three refractive surface models, emphasising the importance of integrating posterior and stromal curvature data into optical assessments.

Conclusion: This study provides the first normative values for stromal curvature and its ratios with anterior and posterior curvature. These findings may have implications for corneal- and lens-based surgeries and diagnostics.

混合AS-OCT对基质曲率、功率和角膜-基质曲率比值的规范值。

背景：建立基质曲率的标准值及其与前后曲率的关系。方法：回顾性观察研究。数据来自75只白内障手术患者，使用高分辨率前段光学相干断层扫描(AS-OCT；MS-39方案)。数据分析包括多个区域（1.0-5.0 mm）的前、间质和后曲率，以及衍生的曲率比。结果：前基质曲率比（ASR）保持稳定（1.016 ~ 1.007），后基质曲率比（SPR）和前基质曲率比（APR）略有变化(SPR: 1.149 ~ 1.167；4月:1.167 - -1.175)。折射率分析揭示了一个、两个和三个折射率表面模型的增量效应，强调了将后曲率和基质曲率数据整合到光学评估中的重要性。结论：本研究提供了间质曲率及其与前后曲率比值的第一个标准值。这些发现可能对基于角膜和晶状体的手术和诊断具有启示意义。

期刊介绍： Clinical & Experimental Ophthalmology is the official journal of The Royal Australian and New Zealand College of Ophthalmologists. The journal publishes peer-reviewed original research and reviews dealing with all aspects of clinical practice and research which are international in scope and application. CEO recognises the importance of collaborative research and welcomes papers that have a direct influence on ophthalmic practice but are not unique to ophthalmology.
