PURPOSE
Case report study of a novel method of fitting large rigid gas-permeable lenses (cornea-scleral, mini-scleral, scleral).
METHODS
Nine patients with different corneal and refractive conditions were fitted with scleral-type rigid gas-permeable lenses using high resolution ocular coherence tomography. All patients achieved excellent visual acuity and comfort. Lenses were well tolerated without significant complications. Three cases are discussed in detail. Two of the 3 patients had previously undergone fitting with trial lenses so that the different methods could be compared with respect to number of lenses used to achieve a final fit.
CONCLUSIONS
High resolution biometry proved to be a highly useful fitting tool and seems to offer a more accurate and efficient alternative to fitting scleral-type lenses compared with the trial lens method.
目的
对一种新型的大尺寸硬性透气性角膜接触镜（角膜巩膜镜、迷你巩膜镜、巩膜镜）验配方法进行病例报告研究。
方法
使用高分辨率光学相干断层扫描技术为9例不同角膜和屈光状况的患者验配巩膜型硬性透气性角膜接触镜。所有患者均获得了极佳的视力和舒适度。镜片耐受性良好，无明显并发症。详细讨论了3个病例。3例患者中有2例此前曾试用过试戴镜片，以便就为达到最终适配所使用的镜片数量对不同方法进行比较。
结论
高分辨率生物测量法被证明是一种非常有用的验配工具，与试戴镜片法相比，似乎为巩膜型镜片的验配提供了一种更准确、更高效的替代方法。
