Abstract

Purpose: The purpose of this study was to determine the clinical utility of computerized corneal topography (CCT) in the fitting of rigid gas permeable (RGP) contact lenses.

Methods: In this prospective study, we compared the clinically determined parameters to those obtained by CCT in 50 consecutive patients who underwent RGP lens fitting. The TMS-1 program was used for CCT, and we fit patients with Boston RGP contact lenses (type II, or Equalens). The final decision on the RGP lenses dispensed relied upon the clinical evaluation (slit lamp examination, fluorescein pattern, lens centration, and visual acuity).

Results: The base curve of RGP lenses proposed by CCT was similar to that selected clinically (mean: 7.74 mm versus 7.81 mm). However, the mean diameter of the CCT proposed lenses was smaller than that selected clinically (9.31 mm versus 9.6 mm, P < 0.01). Divergence was more pronounced in keratoconus.

Conclusions: CCT is an important tool in RGP contact lens fitting. Clinical evaluation remains mandatory in determining the appropriate RGP lens.

目的:本研究的目的是确定计算机角膜地形图(CCT)在硬质透气性隐形眼镜(RGP)配戴中的临床应用。方法:在这项前瞻性研究中，我们比较了50例连续接受RGP晶状体配合术的患者的临床确定参数和CCT获得的参数。TMS-1程序用于CCT，我们为患者配戴波士顿RGP隐形眼镜(II型或Equalens)。最终决定是否配用RGP镜片取决于临床评估(裂隙灯检查、荧光素模式、晶状体浓度和视力)。结果:CCT提出的RGP晶体基底曲线与临床选择的RGP晶体基底曲线相似(平均值:7.74 mm vs 7.81 mm)。然而，CCT建议的晶体平均直径小于临床选择的晶体(9.31 mm比9.6 mm, P < 0.01)。圆锥角膜发散更明显。结论:CCT是RGP隐形眼镜配镜的重要工具。临床评估仍然是确定合适的RGP晶状体的必要条件。
