白内障患者植入可调节性人工晶状体的临床效果

Clinical effect of implantation of accommodating intraocular lens in cataract patients

目的:探索白内障超声乳化术后植入可调节人工晶状体(1CU)的临床治疗效果。方法:并发性白内障2例3眼与老年性白内障20例27眼施行常规超声乳化术。术中植入1CU。术后1a时,观察患者的裸眼远视力、裸眼近视力、屈光状态以及患者的主观感受。结果:裸眼远视力:100%≥0.6,67%≥0.8,27%≥1.0;裸眼近视力:100%≥0.6,73%≥0.7;47%≥0.8;17%≥0.9。术后屈光度在预期矫正度±1.0D以内者为93%,在预期矫正度±0.50D以内者为73%。所有患者均没有出现眩光、光晕及复视等症状的投诉。结论:白内障患者术后植入1CU,可获得一定程度的拟调节力。这种拟调节力有助于改善患者术后的生活质量。

AIM： To evaluate the clinical effect of implantation of accommodating intraocular lens （1CU） after phacoemulcification in cataract patients. METHODS： For 2 cases （3 eyes） with complicated cataract and 20 cases （27 eyes） with senile cataract, phacoemulcification was performed and 1CU IOL was implanted. The uncorrected distance visual acuity, uncorrected near visual acuity, refractive condition and subjective feeling were observed 1a after surgery. RESULTS： The uncorrected distant visual acuity was higher than or equal to 0.6 （100%）, 0.8 （67%）, 1.0 （27%） respectively, and the uncorrected near visual acuity was higher than or equal to 0.6 （100%）, 0.7 （73%）, 0.8 （47%）, 0.g （17%） respectively. The residual refractive errors within ±1.00D, ±0.50D were 93% and 73% respectively. No symptoms such as glare, halo and diplopia were complained by any of the patients. CONCLUSION： The cataract patients could restore certain pseudo-ccommodation power after the implantation of accommodating intraocular lens （1CU）.This kind of pseudo-accommodation power was helpful for improving the life quality of the patients after surgery.
