UNASSIGNED:分析先天性白内障手术合并人工晶状体(IOL)植入后7岁儿童的眼屈光结果。
UNASSIGNED:对143只眼进行了单侧(23只眼)和双侧(60只眼)先天性白内障的人工晶状体植入术的眼部生物特征数据进行了研究。根据手术时的年龄类别将所有儿童分为:A组(0-12个月)-43只眼;B组(12-36个月)-45只眼;和C组(大于36个月)-55只眼。对植入的IOL功率进行了经验性降低:0至36个月的儿童矫正不足20%,36至60个月的儿童矫正不足10%。
未经批准:7岁时,A组的平均伸长率±标准偏差(SD)为3.93±1.64mm,B组2.13±0.94mm,C组0.95±0.76mm(18.7%,9.5%,基线轴向长度的4.1%,分别)。单侧和双侧先天性白内障的轴向伸长率差异无统计学意义(P=0.32)。末次检查平均绝对屈光误差(MAE)为3.99±2.12屈光度(D),2.46±1.48D,A组1.59±1.31D,B,C,分别。在7个月以下的婴儿中,到7岁时,平均伸长率±SD为3.27±2.86mm(25.5%),MAE为3.44±2.1D。术前角膜散光1.0D以上的患病率为48.95%,2.0D以上为27.27%,3.0D以上为5.6%。单侧(1.62±0.77D)和双侧(1.78±0.90D)先天性白内障患者术前角膜散光差异无统计学意义(P=0.56,95%置信区间=-0.50~0.28)。最佳矫正视力(BCVA)超过20/40的占53.49%,55.55%,A组74.54%,B,C,分别。
UASSIGNED:虽然IOL功率是根据儿童的年龄计算的,在7岁的时候,由于生长中的眼睛的生物特征变化,有不同程度的屈光不正,年轻年龄组的屈光异常发生率高于老年年龄组。
UNASSIGNED: To analyze the results of ocular refraction at the age of 7 years in children after congenital cataract surgery with intraocular lens (IOL) implantation.
UNASSIGNED: A
study of ocular biometric data of 143 eyes who underwent lens aspiration with IOL implantation in unilateral (23 eyes) and bilateral (60 eyes) congenital cataracts was performed. All children were divided into groups according to the age categories at the time of surgery: Group A (0-12 months) - 43 eyes; Group B (12-36 months) - 45 eyes; and Group C (older than 36 months) - 55 eyes. An empirical reduction of the implanted IOL power was performed: an undercorrection of 20% in children aged 0 to 36 months and 10% less in children aged 36 to 60 months.
UNASSIGNED: By age 7 years, the mean elongation ± standard deviation (SD) in Group A was 3.93 ± 1.64 mm, 2.13 ± 0.94 mm in Group B, and 0.95 ± 0.76 mm in Group C (18.7%, 9.5%, and 4.1% of the baseline axial length, respectively). There was no significant difference in axial elongation between unilateral and bilateral congenital cataracts (P = 0.32). The mean absolute refraction error (MAE) at last examination was 3.99 ± 2.12 diopter (D), 2.46 ± 1.48 D, and 1.59 ± 1.31 D in Groups A, B, and C, respectively. In infants younger than 7 months of age, by age 7 years, the mean elongation ± SD was 3.27 ± 2.86 mm (25.5%) and MAE was 3.44 ± 2.1 D. The prevalence of preoperative corneal astigmatism of 1.0 D or more was 48.95%, 2.0 D or more was 27.27%, and 3.0 D or more was 5.6%. There was no significant difference in preoperative corneal astigmatism between unilateral (1.62 ± 0.77 D) and bilateral (1.78 ± 0.90 D) congenital cataracts (P = 0.56, 95% confidence interval = -0.50-0.28). Best-corrected visual acuity (BCVA) more than 20/40 was in 53.49%, 55.55%, and 74.54% in Groups A, B, and C, respectively.
UNASSIGNED: Although IOL power was calculated in accordance with children\'s age, at the age of 7 years, there was a different degree of ametropia because of the biometric changes of the growing eye, and a higher rate of ametropia was observed more in the younger age group than in the elder age groups.
