Scleral contact lenses are used to treat symptoms of severe dry eyes. Procedures for fitting scleral lenses have been vague because of lack of standardized guidelines. This retrospective case series sought to establish average vault over central cornea in successful scleral lens wearers with dry eyes.
Anterior segment optical coherence tomography was used to measure the distance between the posterior lens surface and cornea in 20 eyes of 12 consecutive patients successfully fit in the Vanderbilt Scleral Lens Clinic.
Mean vault was 380 ± 110 μm. There was no correlation between vault and corneal curvature or vault and visual acuity.
With a large SD in average vault, precision in central vault does not seem to be important in scleral contact lenses for successful fit for dry eyes.
巩膜接触镜用于治疗严重干眼症的症状。由于缺乏标准化指南，巩膜镜验配程序一直不明确。本回顾性病例系列旨在确定成功佩戴巩膜镜的干眼症患者中央角膜上方的平均拱高。
对范德比尔特巩膜镜诊所成功验配的连续12例患者的20只眼，使用眼前节光学相干断层扫描测量晶状体后表面与角膜之间的距离。
平均拱高为380±110μm。拱高与角膜曲率或拱高与视力之间无相关性。
平均拱高的标准差较大，对于成功佩戴治疗干眼症的巩膜接触镜而言，中央拱高的精确性似乎并不重要。
