目的探讨超声乳化白内障吸除可调节人工晶状体植入术的临床疗效和调节幅度。方法对75例(94只眼)白内障患者行超声乳化白内障吸除1CU型可调节人工晶状体植入术,观察并记录术眼的主观屈光状态、裸眼远视力、裸眼近视力、最佳矫正远视力、30cm处远视力矫正后近视力、30cm处最佳矫正近视力、主观调节幅度(分别采用主观移近法和负镜片法测量)。术后随访时间1～12个月,对术后1周、1个月及3个月的资料进行分析。结果术后1周、1个月及3个月裸眼近视力≥Jr5者分别占81.9%(77/94)、85.1%(80/94)及84.0%(79/94);远视力矫正后近视力≥Jr5者分别占78.7%(74/94)、79.8%(75/94)及74.5%(70/94)。采用主观移近法和负镜片法检查调节幅度,术后1周分别为(1.96±0.63)D(0.75～4.50D)和(1.74±0.59)D(0.75～4.50D),术后1个月分别为(1.89±0.54)D(0.75～3.25D)和(1.68±0.47)D(0.75～3.25D),术后3个月分别为(1.77±0.53)D(0.75～2.75D)和(1.66±0.50)D(0.75～2.75D)。术后1周、1个月及3个月2种方法测量的主观调节幅度比较,差异均无统计学意义(P>0.05)。远视力矫正后近视力和调节幅度之间为正相关(P=0.00)。结论早期观察结果显示1CU型可调节人工晶状体植入术后视功能恢复良好,患者在具有较好远视力的同时,具备良好的视近能力。远期效果有待进一步观察。
Objective To investigate the clinical efficacy and amplitude of phacoemulsification and intraocular lens implantation. Methods 75 cases (94 eyes) of cataract patients underwent phacoemulsification cataract extraction with intraocular lens implantation (ICU), observe and record the subjective refractive status, uncorrected visual acuity, naked eye near vision, the best correction far Visual acuity, near 30cm after vision correction near vision, 30cm best corrected near vision, subjective adjustment range (respectively by subjective approach and negative lens method). The patients were followed up for 1 to 12 months. The data of 1 week, 1 month and 3 months after operation were analyzed. Results One week, one month and three months postoperatively, 81.9% (77/94), 85.1% (80/94) and 84.0% (79/94) had visual acuity Those with ≥ ≥5 were 78.7% (74/94), 79.8% (75/94) and 74.5% (70/94), respectively. The subjective approach and negative lens were used to examine the amplitude of adjustment. The postoperative week was (1.96 ± 0.63) D (0.75 ~ 4.50D) and (1.74 ± 0.59) D (0.75 ~ 4.50D) (1.89 ± 0.54) D (0.75-3.25D) and (1.68 ± 0.47) D (0.75-3.25D) respectively at 3 months postoperatively were (1.77 ± 0.53) D (0.75-2.75D) and ± 0.50) D (0.75-2.75D). There was no significant difference in subjective adjustment between the two methods at 1 week, 1 month and 3 months after operation (P> 0.05). There was a positive correlation between near visual acuity and accommodation after distance vision correction (P = 0.00). Conclusion The results of early observation showed that the functional recovery after ICU-IOL implantation was good. Patients with good distance vision had good visual acuity. Long-term results need to be further observed.
