三焦点人工晶状体植入术后长期临床观察

Long-term clinical observation after trifocal intraocular lens implantation

目的观察三焦点人工晶状体(IOL)植入术后长期疗效。方法选取行三焦点IOL植入术的患者30例(50只眼),于术后6个月及12个月分别测试及随访。比较术后6、12个月视力情况、离焦曲线、后发性白内障、问卷调查结果。结果术后6个月远视力(0.038±0.06),中间视力(0.112±0.063),近视力(0.078±0.058);术后12个月远视力(0.040±0.049),中间视力(0.108±0.06),近视力(0.060±0.053)。术后12个月与6个月远、中、近视力比较差异均无统计学意义(F=0.03、0.106、2.596,P>0.05)。术后6、12个月患者离焦曲线均在0.0 D处为最高峰,在+1.0 D^-2.5 D离焦范围内平缓且处于较高值,视力均>0.2 LogMAR。所有患者中仅一眼术后8个月时发生较明显后囊膜混浊,并行YAG激光切开治疗,激光后视力恢复至术后3个月水平。所有患者中有2只眼出现光晕,但不影响其日常生活,未见其他不适。结论三焦点IOL植入可长期为患者提供良好的全程视力,且患者主观满意度较高,视觉质量较好。

Objective To observe the long-term efficacy of trifocal intraocular lens(IOL)implantation.Methods A total of 30 patients(50 involved eyes)with trifocal IOL implantation in our hospital were tested and followed-up for 6 and 12 months after surgery.The visual acuity,defocusing curve,post-cataract and questionnaire survey results 6 and 12 months after surgery were compared.Results 6 months after surgery,the far vision,intermediate vision and near vision were(0.038±0.06),(0.112±0.063)and(0.078±0.058),which were(0.040±0.049),(0.108±0.06)and(0.060±0.053)12 months after surgery.There was no statistically significant difference in far,intermediate and near vision between 12 months and 6 months after surgery(F=0.03,0.106,2.596,P>0.05).6 and 12 months after surgery,the defocusing curve of the patients was the highest at 0.0 D,and the defocusing curve was gentle and high in the range of+1.0 D to-2.5 D,and the visual acuity was>0.2 LogMAR.In all patients,only 1 eye had significant posterior capsule opacification 8 months postoperatively.After YAG laser incision,the visual acuity recovered to 3 months postoperatively.Halo appeared in 2 eyes of all patients,but it did not affect their daily life,and no other discomfort was found.Conclusion Trifocal IOL implantation implantation can provide good whole course vision for a long time,and patients have higher subjective satisfaction and better visual quality.
