【摘要】：目的探討配戴角膜塑形鏡矯正近視對角膜形態(tài)的變化和影響。方法采用美國進口EE公司提供的角膜塑型鏡(夜戴型),矯治青少年近視118例(235眼)中、低度近視(-4.75±1.85)D,分別測量戴鏡前和戴鏡后1周、2周、1個月和3個月角膜曲率(K值)、角膜厚度及裸眼視力,采用t檢驗分析。結(jié)果戴鏡后角膜曲率明顯下降,與戴鏡前比較差異有統(tǒng)計學(xué)意義(P0.05);戴鏡后2周、1個月、3個月與戴鏡后1周比較差異無統(tǒng)計學(xué)意義(P0.05)。戴鏡后角膜中央厚度變薄,與戴鏡前比較差異有統(tǒng)計學(xué)意義(P0.05),戴鏡后2周、1個月、3個月與戴鏡后1周比較差異無統(tǒng)計學(xué)意義(P0.05)。裸眼視力明顯提高,與戴鏡前比較差異有統(tǒng)計學(xué)意義(P0.05),戴鏡后2周、1個月、3個月與戴鏡后1周比較差異無統(tǒng)計學(xué)意義(P0.05)。結(jié)論配戴角膜塑形鏡后角膜中央變平坦、中央厚度變薄。主要變化表現(xiàn)在戴鏡后1周之內(nèi),1個月趨于穩(wěn)定。角膜上皮無損傷,裸眼視力明顯提高。
[Abstract]:Objective to investigate the effect of wearing corneal plastic lens on corneal morphology in correction of myopia. Methods 118cases (235eyes) of juvenile myopia were treated with corneal plastic lens (night wear type) provided by EE Company. The low myopia was (- 4.75 鹵1.85D) D. before and 1 week and 2 weeks after wearing the lens, respectively. The corneal curvature (K value), corneal thickness and uncorrected visual acuity at 1 month and 3 months were analyzed by t test. Results the corneal curvature decreased significantly after wearing the lens, which was significantly different from that before wearing the lens (P 0.05), but there was no significant difference between 2 weeks, 1 month, 3 months and 1 week after wearing the lens (P 0.05). The central corneal thickness became thinner after wearing the lens, which was significantly different from that before wearing the lens (P 0.05), but there was no significant difference between 2 weeks, 1 month, 3 months and 1 week after wearing the lens (P 0.05). The uncorrected visual acuity was significantly improved compared with that before wearing the mirror (P 0.05), but there was no significant difference between 2 weeks, 1 month, 3 months and 1 week after wearing the mirror (P 0.05). Conclusion after wearing corneal plastic lens, the center of the cornea becomes flat and the thickness of the center becomes thinner. The main changes were within 1 week after wearing the mirror, and tended to be stable within 1 month. There was no corneal epithelial injury and uncorrected visual acuity was significantly improved.
