An in-office clinical investigation to determine the fitting success rate and frequency and reasons for lens performance failure was conducted, using the Tangent Streak, a new rigid gas permeable bifocal contact lens. The patient population consisted of 34 highly screened presbyopic patients qualifying for a translating bifocal lens. The results revealed nearly 60% of all eyes were fitted successfully with the first lens ordered and an additional 22.4% met success criteria after a second lens order, for a total of 82.1% success. The average number of lenses needed to attain success was calculated to be 1.8 lenses per eye. Analysis of reasons for lens reorder, and frequency and types of lens modification is also summarized, and provides added information regarding the "customized" nature of this specialty lens.
使用新型刚性透气双焦点隐形眼镜Tangent Streak进行了一项门诊临床研究，以确定配镜成功率、镜片性能失败的频率及原因。患者群体包括34名经过严格筛选、适合佩戴平移双焦点镜片的老花眼患者。结果显示，近60%的眼睛在首次订购镜片时就成功配镜，另有22.4%在第二次订购镜片后达到成功标准，总成功率为82.1%。每只眼睛达到成功所需的镜片平均数量经计算为1.8片。还总结了镜片重新订购的原因以及镜片修改的频率和类型分析，并提供了有关这种特殊镜片“定制”性质的更多信息。
