Computerized videokeratoscopy systems now allow interactive rigid gas permeable (RGP) fitting evaluation using fluorescein pattern simulations through updated software programs. We used Computed Anatomy's Topographic Modeling System-1 (TMS-1) Custom Design Contact Lens Program successfully to refit a symptomatic bilateral post-penetrating keratoplasty patient. No trial lenses were used. For each eye the base curve, optic zone size, and edge lift were chosen from the optimal fluorescein pattern designed and titrated on the TMS-1 unit. Lens powers were based on the patient's previous lenses and overrefraction. Dispensed lenses provided a clinically acceptable fit, good comfort, and maximal visual acuity, and no adjustments were necessary. Corneal videokeratoscopy can be successfully employed to titrate an RGP fit, even on irregular corneas.
计算机化的角膜地形图系统现在允许通过更新的软件程序，使用荧光素模式模拟进行交互式硬性透气性（RGP）镜片验配评估。我们成功地使用了计算机解剖学的地形建模系统-1（TMS-1）定制设计隐形眼镜程序，为一名有症状的双侧穿透性角膜移植术后患者重新配镜。未使用试验镜片。对于每只眼睛，基弧、光学区大小和边缘翘起度是根据在TMS-1设备上设计并调整的最佳荧光素模式来选择的。镜片度数基于患者之前的镜片和过矫验光结果。所配镜片提供了临床上可接受的适配性、良好的舒适度和最佳视力，无需进行调整。即使对于不规则角膜，角膜地形图也可成功用于调整RGP镜片的适配。
