Keratometric readings on 132 different eyes were examined from the patient records. Sixty eyes had previously worn polymethyl methacrylate (PMMA) lenses and then were refitted with the Boston II gas-permeable contact lens. The remaining 72 eyes had never worn contact lenses and these too were fitted with the Boston II lens. The Boston II contact lens is a nonhydrophilic contact lens composed of methylmethacrylate-dimethylitaconate-siloxanyl copolymer with a reported Dk value of 14.6 X 10(-11) ml O2 cm2/s ml mm Hg (35 degrees C). The mean and SD of the keratometric readings and the amount of corneal toricity found were calculated for each set of progress reports. The data in this study indicate that an alignment-fitting Boston II gas-permeable contact lens does not cause curvature changes in corneas during the first three months of wear.
从患者记录中检查了132只不同眼睛的角膜曲率读数。其中60只眼睛曾佩戴过聚甲基丙烯酸甲酯（PMMA）镜片，之后改用波士顿II型透气硬镜。其余72只眼睛从未佩戴过隐形眼镜，这些眼睛也佩戴了波士顿II型镜片。波士顿II型隐形眼镜是一种非亲水性隐形眼镜，由甲基丙烯酸甲酯 - 衣康酸二甲酯 - 硅氧烷基共聚物组成，据报道其Dk值为14.6×10（-11）ml O2 cm2/s ml mmHg（35摄氏度）。针对每组进展报告计算了角膜曲率读数的平均值和标准差以及角膜散光量。本研究中的数据表明，配适的波士顿II型透气硬镜在佩戴的前三个月不会导致角膜曲率变化。
