摘要
目的以小切口手法碎核术对比分析超声乳化术对高度近视合并白内障患者视觉质量的影响,以探讨其临床应用价值。方法选取本院收治的高度近视合并白内障单眼病变患者72例,以随机数字表分为观察组和对照组各36例;对照组采用小切口手法碎核术和人工晶状体植入术进行治疗,观察组采用超声乳化术和人工晶状体植入术进行治疗。根据患者个体情况随访6-12个月,记录最佳矫正视力和并发症发生情况;并分别于治疗后1周、3个月及6个月常规检查术源性散光、屈光状态、中央角膜厚度（CCT）、角膜细胞计数（CEC）、角膜敏感度及黄斑中心凹视网膜厚度（CMT）。结果术前,两组患者的BCVA无统计学差异（P〉0.05）;术后,两组患者BCVA均有显著改善（P〈0.001）,且观察组明显优于对照组（P〈0.05）。术前,两组患者的各项角膜、黄斑区及相关光学指标无统计学差异（P〉0.05）;术后,观察组各时间段的术源性散光度和CMT显著小于对照组（P〈0.001）,角膜敏感度显著优于对照组（P〈0.001）。此外,观察组的角膜水肿发生率显著低于对照组（P〈0.05）,但总并发症发生率无统计学差异（P〉0.05）。结论超声乳化术相对封闭的操作环境能够维持前房稳定性,利于保护角膜神经,提高高度近视合并白内障患者的术后视觉质量。
Objective To explore the clinical effect of phacoemulsification in the treatment of cataract with high myopia by a contrastive analysis with small incision technique broken nuclear surgery.Methods 72 cataract patients with high myopia were selected and randomly divided into control group and observation group,36 cases in each group.Patients in the control group were treated with small incision technique broken nuclear surgery,and in the observation group were treated with phacoemulsification.Patients were all given intraocular lens implantation surgery.A follow-up of 6 to 12 months were complicated,and the best corrected visual acuity（BCVA） and complications were recorded.Astigmatism,diopter,central corneal thickness（CCT）,corneal endothelial cell（CEC）,central macular thickness（CMT） and corneal sensitivity were also analyzed.Results There was no significant difference in BCVA between the 2 groups before treatment（ P〉0.05）,but BCVA improved significantly after treatment in the two groups（P〈0.001）,and BCVA in the observation group were higher than that in the control group（ P〉0.05）.There was also no significant difference in other indexes between the 2 groups before treatment（P〉0.05）,but the astigmatism and CMT in the observation group were lower than those in the control group（P〈0.001）,and the corneal sensitivity in the observation group was higher than that in the control group（ P〈0.001）.The corneal edema rate in the observation group was significantly lower than that in the control group（ P〈0.05）,and there was no significant difference in the total complication rate（P〉0.05）.Conclusion Phacoemulsification had some advantage on maintaining the stability of the anterior chamber,and could improve the postoperative visual quality of cataract patients with high myopia.
