等效球面度取代最佳散光矫正屈光度对眼压影响

Effect of the Equivalent Spherical Instead of Optimal Astigmatic Diopter on Intraocular Pressure

本研究目的建立以远方视力最佳散光矫正镜片与等效球面镜片结合单极点脑波撷取器与眼压计进行散光眼屈光矫正与视觉舒适之技术。低散光被检者依次配戴最佳矫正镜片与等效球面镜片之后,视力皆处于清晰状况,经单极点脑波撷取器量测结果都显示专注。低散光被检者依次配戴最佳矫正镜片及等效球面镜片,配戴时间各15分钟,分别作眼压测量。测试结果配戴等效球面镜片眼压高于最佳矫正镜片,右眼与左眼眼压各增加3.33 mmHg与2.00 mmHg。高散光被检者实验方法同上,眼压测试结果与低散光一致,右眼与左眼各增加1.33 mmHg及0 mmHg。由量测眼压数据得知配戴等效球面镜片视觉舒适度是无法持久,在低度散光者亦不可轻忽矫正镜片之选择,方可提高视觉持久度及舒适度。

The purpose of this study is to establish a technique for astigmatism refractive correction and visual comfort with the best corrective glasses of distance vision and equivalent spherical glass-es combined with a single pole brain wave capture device and tonometer. After the low astigma-tism subjects wear with the best corrective glasses and equivalent spherical glasses in turn, the vision was in a clear state, and the brain waves captured by the single pole brain wave capture device test results show attention. Low astigmatic subjects were fitted with best correction glasses and equivalent spherical glasses, each with a wearing time of 15 minutes, respectively, for intraocular pressure (IOP) measurement. Equivalent spherical lens wear test results intra-ocular pressure above the optimal corrective lenses, right eye and left eye IOP increased by 3.33 mm and Hg 2.00 mmHg. The test method of high astigmatism was the same as that of low astig-matism. The test results are consistent with IOP of low astigmatism, and IOP of the right eye and the left eye was increased by 1.33 mmHg and 0 mmHg respectively. From the measurement of intraocular pressure data, it is known that the visual comfort of wearing the equivalent spheri-cal glasses is not durable, and the low astigmatism subjects should not neglect the choice of the corrected glasses, so as to improve the visual durability and comfort.
