摘要
目的总结RoseK硬性透气性角膜接触镜（RoseKRGPCL）矫正完成期圆锥角膜患者屈光不正的临床效果。方法回顾性病例研究。2011年2月至2012年5月，55例（59眼）完成期圆锥角膜患者在山东省眼科医院接受了RoseKRGPCL验配矫正，用角膜荧光染色法判断戴RoseKRGPCL静态配适状态。对戴RGPCL前角膜地形图9mm直径上0°、90°、180。、270°4个点和锥顶角膜曲率值之间，裸眼视力（UCVA）、最佳眼镜矫正视力（BSCVA）和戴RoseKRGPCL矫正视力之间，UCAV、BSCAV和戴RoseKRGPCL3种状态下对比度视力之间，角膜平、陡、平均曲率半径及镜片基弧之间的差异采用方差分析进行比较。结果59眼角膜地形图周边4个点和锥顶角膜曲率两两比较，锥顶与周边4组差异均有统计学意义（P均〈0．01）；相同对比度下UCVA、BSCVA及戴RoseKRGPCL矫正视力两两比较差异均有统计学意义（P均〈0．01）；镜片基弧与角膜平K、平均曲率半径两两比较差异均无统计学意义（P〉0．05）。结论完成期圆锥角膜患者验配RoseKRGPCL镜片能达到理想配适状态并获得较好的矫正视力及低对比度视力：验配过程中平坦曲率半径或平均曲率半径可以做为选择试戴片的基础。
Objective To observe the clinical outcome of the Rose K rigid gas permeable contact lens （RGPCL） used to correct advanced keratoeonus with refractive errors. Methods Fifty-nine eyes of 55 patients with advanced keratoconus who were fitted at the Shandong Eye Hospital with a Rose K RGPCL between February 2011 and May 2012 were included in this retrospective study. Fluoresein staining was used to fit the contacts lenses. Differences in mean values among groups were compared with a one-way ANOVA. The corneal curvature values of a 9 mm diameter centered on the apex of the topographic map were compared for the 4 meridians of 0~, 90~, 180~, 270~. Uncorrected visual acuity （UCVA）, best spectacle-corrected visual acuity （BSCVA） and best-corrected RGPCL visual acuity （RGPCLVA） were compared. Visual acuity under the same contrast were compared for UCVA, BSCVA and RGPCLVA. The curvature radius of the flat meridian （Sire K1）, steep meridian （Sim K2）, and mean K were compared with the base curve （BC） of the RGPCL. Results There were significant differences between the corneal curvature values of the 4 peripheral points and the apex on the topographic map （P〈0.01）. The Rose K RGPCL reached an ideal fit by fluoresein staining. There were statistically significant differences between RGPCLVA and UCVA or BSCVA （P〈0.01）. And the same outcomes were found for the 100%, 25%, 10% and 5% contrast visual acuity charts. There were no significant differences in the relationship between the BC of RGPCL and the residual Sim K1 or mean K. Conclusion The Rose K RGPCL lenses provide ideal fitting, good visual acuity and contrast vision for advanced keratoeonus. The trial Rose K RGPCL was chosen based on the Sire K1 or mean K.
