【摘要】：目的比较青少年近视患者配戴角膜塑形镜、硬性透气性角膜接触镜(rigid gas permeable contact lens,RGPCL)及框架眼镜2 a后屈光度及眼轴长度变化,评估不同光学矫正方式对青少年近视的控制效果。方法前瞻性临床研究。收集2012年6月至2014年6月验配角膜塑形镜的近视者50例(99眼)为角膜塑形镜组、RGPCL近视者48例(95眼)为RGPCL组及单光足矫框架眼镜近视者50例(100眼)为框镜组,随访2 a。记录三组患者戴镜前及戴镜2 a后的近视球镜度、柱镜度、等效球镜度(spherical equivalent,SE)、眼轴长度(axial length,AL)及角膜塑形镜组戴镜6个月内每次复查时裸眼视力(uncorrected visual acuity,UCVA)。为准确测量屈光度及AL,角膜塑形镜组和RGPCL组2 a后至少停戴30 d再进行检查。结果戴镜前3组间年龄、屈光状态、AL等比较,差异均无统计学意义(均为P0.05)。2 a后,三组的AL及SE均有所增加(F=278.43、140.12,均为P0.01),AL和SE增加分别为:角膜塑形镜组(0.30±0.39)mm、(0.83±0.97)D,RGPCL组(0.55±0.41)mm、(1.55±0.63)D,框镜组(0.59±0.34)mm、(1.73±0.62)D,角膜塑形镜组增加量最少,另两组增加量差异无统计学意义。角膜塑形镜组戴镜后各时间点的UCVA较配戴前均明显提高(F=486.38,P0.01)。结论角膜塑形镜、RGPCL及框架眼镜3种光学矫正方式对青少年近视进展的控制作用以角膜塑形镜效果最佳,配戴角膜塑形镜还能明显提高近视者的UCVA。
[Abstract]:Objective to compare the changes of diopter and axial length in juvenile myopia patients after wearing rigid gas permeable contact lensus (RGPCL), rigid gas permeable contact lens and frame glasses for 2 years. To evaluate the control effect of different optical correction methods for juvenile myopia. Methods prospective clinical study. From June 2012 to June 2014, 50 cases (99 eyes) of myopia with corneal plastic lens were collected as RGPCL myopia. 48 cases (95 eyes) were treated with RGPCL and 50 cases (100 eyes) with single light foot frame glasses. Follow up for 2 years. The myopia degree of ball and column were recorded before and 2 years after wearing mirror in the three groups. The axial length of the eyes and the cornea plastic lens group were examined at least 30 days after wearing the lens for 6 months. In order to accurately measure the diopter and ALS, the uncorrected visual acuity of the cornea plastic lens group and the RGPCL group were stopped for at least 30 days after wearing the lens within 6 months. In order to measure the diopter and AL1 accurately, the corneal plastic lens group and the RGPCL group stopped wearing at least 30 days after wearing the lens. Results the age of the three groups before wearing the mirror, There was no significant difference in the refractive state of AL between the three groups (P 0.05a, P 0.05a). The levels of AL and SE in the three groups were increased (P 0.01, P 0.01, P < 0.01) and SE were 0.30 卤0.39 mm, 0.83 卤0.97DRGPCL, 0.59 卤0.34mm, 1.73 卤0.62D, respectively, and 0.55 卤0.41 卤0.63d, respectively, and 0.59 卤0.34mm, 1.73 卤0.62D, respectively, in the RGPCL group, 0.59 卤0.34mm and 1.73 卤0.62D, respectively. There was no statistical difference between the other two groups. The UCVA of the corneal plastic lens group at each time point after wearing the lens was significantly higher than that of the pre-wear group. Conclusion the three optical correction methods of corneal plastic lens and framing glasses for juvenile myopia are significantly higher than those before wear. Conclusion the three optical correction methods of corneal plastic lens and framing glasses are useful for the development of juvenile myopia. The best control effect is the corneal plastic lens. Wearing corneal plastic lens can also significantly improve the UCVA of myopia.
