目的 :观察高度近视白内障并低视力患者行白内障超声乳化 +人工晶状体植入手术后视力变化。方法 :高度近视白内障并低视力患者 2 5例 40只眼 ,术前常规眼部检查 ,散瞳详细检查眼底并记录 ,使用检影验光和综合验光仪精确验光 ,汉字阅读视力表检查最佳近视力 ,手术后 6个月至 2年后进行随访 ,再次精确验光和近视力检查 ,并调查近阅读情况。结果 :(1)远视力 :2 5例 40只眼矫正远视力明显优于术前 ,5例 10只眼矫正视力≥ 0 3 ,等效球镜度为 -1 75～ -3 75D ,2 0例 3 0只眼 <0 3 ,等效球镜度为 -1 75～ -4 0 0D ;(2 )近视力 :手术后测最佳近视力明显下降 ,3 0只低视力眼最佳近视力三号字 /2 5cm ,最差不能看清初号字 ;(3 )近阅读情况调查 :3 0只低视力眼均反映近视力下降 ,出现近阅读困难 ,不能阅读书报 ;在 5例10只眼矫正视力≥ 0 3中也表现近视力下降 ,4例出现近阅读困难。 (4)解决方法 :2 0例 3 0只低视力眼患者近阅读时配戴正高屈光度数眼镜 ,移近目标至足够近距离进行阅读 ,度数 + 4 50～ + 13 0 0D ,平均 + 7 82D ,除 1只眼因黄斑功能差配戴近阅读镜近视力为四号字 / 10cm ,其余均能够完成近阅读。在 4例 8只眼矫正视力≥ 0 3中同样验配近阅读眼镜 ,屈光度 + 3 0 0～+ 6 2 5D ,完成近阅读。结?
Objective: To observe the changes of visual acuity after cataract phacoemulsification and intraocular lens implantation in cataract with high myopia and low vision. Methods: 25 eyes of 40 eyes with high myopia and low visual acuity were examined with routine ophthalmoscopy and mydriasis. The eyes were recorded and examined with optometry and optometry. Force, 6 months to 2 years after surgery for follow-up, again accurate optometry and near vision examination, and investigate the recent reading. Results: (1) Distance vision: 25 cases of 40 eyes were significantly better than preoperative correction of far vision, 5 cases of 10 eyes corrected visual acuity ≥ 0 3, spherical equivalent degrees of -1 75 ~ -3 75D, 2 0 Example 3 0 eyes <0 3, the equivalent spherical power of -1 75 ~ -4 0 0D; (2) near vision: after surgery, the best near vision decreased significantly, 30 low vision best ophthalmic The third word / 2 5cm, the worst can not see the first character; (3) the recent reading survey: 30 low vision eyes all reflect near vision loss, there is reading difficulties, can not read books and newspapers; in 5 cases of 10 Eyes corrected visual acuity ≥ 0 3 also showed near vision loss, 4 cases of nearly reading difficulties. (4) solution: 20 cases of 30 patients with low vision eye wear reading glasses near the high diopter, moving closer to the target to close enough to read, the degree of +4 50 ~ +13 0 0D, an average of +7 82D , Except for 1 eye due to poor macular function with reading glasses close to the fourth character / 10cm, the rest can be completed near reading. In 4 cases 8 eyes corrected visual acuity ≥ 0 3 in the same fitting near reading glasses, diopter + 300 ~ + 6 2 5D, completed near reading. Knot?
