老年白内障患者人工晶状体眼调节融合的研究

Research of accommodation and fusion among patients with cataract extraction and intraocular lensimplantation

目的应用综合验光仪和同视机立体视图检查白内障患者术后的调节、融合结果，探讨其双眼视觉功能恢复情况。方法2008年8月至2010年8月选择接受白内障手术的单眼白内障患者42例42只眼作为单眼组，选择同期接受白内障手术的双眼白内障患者40例80只眼作为双眼组，同期接受门诊治疗的老年患者35例作为对照组，应用综合验光仪对3组人群进行客观验光、双眼平衡等常规屈光定量检查，同时进行双眼同时视、双眼融合机能、调节与集合以及调节性集合与调节比值（AC／A）等视觉功能的定性或定量分析。结果3组患者的调节因素中，调节近点、正负相对调节、调节反应和调节幅度差异显著。在调节与融合因素中，3组患者的调节性集合与调节比值（AC／A）无显著差异；3组患者的融合范围比较差异显著。结论白内障术后无论单眼或双眼仍然存留一定的调节能力，目．具有一定的融合功能。双眼白内障患者的调节融合优于单眼白内障患者，但与正常者相比脯差异。

Objective To check the result of accommodation and fusion among patients withcataract extraction and intraocular lens implantation by using optometry uni and synoptophore, and discuss the recovery of binocular vision function. Methods 42 patients （42 eyes）with unilateral cataract, 40 patients （80 eyes）with binoculus cataract, and 35 gerontal patients in our hospital were chosen from August 2008 to August 2010. We used optometry uni routinely to check objective optometry and binoculus balance. At the same time, qualitatively or quantitatively analyze binoculus simultaneous perception, binocular integration function, accommodation, aggregation, and accommodative convergence/accommodation and so on. Results Statistical analysis showed that three groups were statistically significant in the factors of regulation, regulation near point, positive and negative relative accommodation, accommodative response and accommodative amplitude. No significant difference in the factors of the regulation and integration and the adjustment of the ratio （AC/A）. The difference in scope of the integration was statistically significant between three groups of patients. Conclusions After cataract extraction and intraocular lens implantation, either one or both eyes after cataract surgery still retains some ability to regulate, and the integration of certain functions. Binocular cataract group has better accommodation and fusion than the unilateral cataract group, but still exists some difference compared with normal control.
