| 摘要 目的：观察年龄相关性白内障行透明角膜切口超声乳化吸除及人工晶体植入术后角膜曲率的变化及相对稳定的时间。方法：收集2016年6月-8月在哈尔滨医科大学附属第一医院伍连德纪念医院进行的3.0 mm透明角膜切口白内障超声乳化吸除及人工晶体植入术的患者200例216眼，其中男88例、女128例，平均年龄71.2岁，进行相应的术前检查，并检查术前、术后第一天、一周、一个月、和三个月时的角膜曲率、视力、眼压并行相应的统计学分析。结果：术后不同时间点视力>0.5的恢复情况：第一天为147眼（68.05 %）、一周为175眼（81.02 %）、一个月为193眼（89.35%）、三个月为197眼（91.20 %）；术前角膜曲率为43.94±1.35、术后第一天、术后一周的角膜曲率分别为44.98±1.06、44.45±1.18，与术前相比有显著性差异（p<0.05），术后一个月、三个月的角膜曲率分别为44.13±1.27、44.02±1.24,与术前相比无显著性差异（p>0.05）；术源性散光于术后一天达到最大，随后逐渐减小，术后一个月、三个月与术后一天比较有显著性差异（p<0.05），术后三个月与一个月比较无显著性差异（p>0.05），术源性散光术后逐渐下降，并于一个月时趋于稳定。结论：3.0 mm透明角膜切口白内障超声乳化吸除及人工晶体植入术患者在术后一个月的角膜曲率基本稳定，恢复至术前状态，屈光状态趋于稳定，术源性角膜散光较小，术后视力恢复至较好状态。 |

| ABSTRACT Objective: To observe the changes and the relatively stable time of corneal curvature after phacoemulsification(PHACO) and IOL implantation on age-related cataract patients with transparent corneal incision. Methods: A total of 200 patients (216 eyes) with 3.0 mm transparent corneal incision cataract phacoemulsification and IOL implantation were collected in the hospital of the First Affiliated Hospital of Harbin Medical University (Wu Liande Memorial Hospital)from June 2016 to August 2016. Among them, 88 males, 128 females, mean age 71.2 years old. Performed relative examination before the operation, and check the corneal curvature, vision, intraocular pressure of preoperative, first day after operation, first week after operation, first month after operation, and three months after operation, and perform the corresponding statistical analysis. Results: After surgery, the recover of vision which better then 0.5 at different time: the first day was 147 eyes (68.05 %), one week was 175 eyes (81.02 %) , one month was 193 eyes (89.35 %) and the three month was 197 eyes (91.20 %). The preoperative corneal curvature was 43.94±1.35, postoperative the first day and the first week corneal curvature respectively of 44.98±1.06, 44.45±1.18, compared with the preoperative have significant difference (p < 0.05), one month and three months after the corneal curvature were 44.13±1.27, 44.02±1.24, compared with the preoperative was no statistically significant difference (p < 0.05); Intraoperative astigmatism reached its maximum on the first day after surgery, then gradually decreased, there was a significant difference between one month, three months and one day after surgery (p < 0.05). There was no significant difference between three months and one month after surgery (p < 0.05). Intraoperative astigmatism decreased gradually and stabilized in a month. Conclusion: Patients with 3.0 mm transparent corneal incision cataract phacoemulsification and IOL implantation was stable in one month after operation, and recovery to preoperative status. Refractive status tends to be stable and the less invasive corneal astigmatism, Postoperative visual acuity returned to a better condition. |
