摘要:

背景:单焦点与多焦点Toric散光型人工晶体具有良好的生物学特性和光学特性,植入后更为安全和稳定,目前已被临床广泛使用。

目的:比较单焦点与多焦点Toric人工晶体植入治疗白内障角膜散光后的疗效和旋转稳定性。
方法:纳入接受超声乳化联合人工晶体植入治疗的白内障角膜散光患者210例,其中105例植入单焦点Toric人工晶体,另105例植入多焦点Toric人工晶体。植入后1周、3周、1个月复查裸眼视力、最佳矫正视力及残余散光,检测人工晶体旋转度,记录并发症发生率与脱镜率。
结果与结论:两组人工晶体植入1周后的视力、残余散光均较植入前明显改善(P < 0.05),并且植入时间越长改善效果越明显;多焦点人工晶体组视力、残余散光改善效果优于单焦点人工晶体组。两组人工晶体植入后均发生了旋转,但两组旋转角度均在5°以内,多焦点人工晶体组不同时间点的人工晶体旋转度高于单焦点人工晶体组(P < 0.05)。两组植入后1个月的并发症发生率及脱镜率比较差异无显著性意义。表明多焦点Toric人工晶体可有效矫正视力及散光,单焦点Toric人工晶体具有较高的旋转稳定性。

Abstract:

BACKGROUND: Monofocal and multifocal Toric intraocular lens that have been widely used in clinic exhibit xcellent biological and optical characteristics and have good safety and stability after implantation.

OBJECTIVE: To compare the outcomes and rotation stability in patients with cataract and astigmatism after implantation of monofocal and multifocal intraocular lens.
METHODS: A total of 210 patients with cataract and astigmatism who received phacoemulsification and intraocular lens implantation were included in this study. Of them, 105 patients were assigned to monofocal intraocular lens implantation and the other 105 patients to multifocal intraocular lens implantation. Uncorrected visual acuity, best corrected visual acuity, residual astigmatism were reexamined at 1, 3 weeks and 1 month after surgery. The rotation of Toric intraocular lens was determined. The incidence of complications and spectacles- independent rate were recorded.
RESULTS AND CONCLUSION: Visual acuity and residual astigmatism in each group were significantly improved after 1 week of intraocular lens implantation (P < 0.05); furthermore, these two indicators became better over time. Improvement of visual acuity and residual astigmatism in multifocal intraocular lens group was more obvious than that in monofocal intraocular lens group. Postoperative intraocular lens rotation at < 5° occurred in both groups. The intraocular lens rotation degree in multifocal intraocular lens group was higher than that in monofocal intraocular lens group at different time points (P < 0.05). There were no significant differences in incidence of complications and spectacles-independent rates between two groups at 1 month after surgery. These results demonstrate that multifocal Toric intraocular lens provides better visual acuity and residual astigmatism improvement, while monofocal Toric intraocular lens provides better rotation stability.
