To evaluate the postoperative ocular axial length in children, who had unilateral cataract extraction with intraocular lens implantation.
In this retrospective study we studied 20 children (12 boys and 8 girls) in age from 7 to 20 years (mean 14 +/- 3.65 years), who had undergone surgery for unilateral cataract: 8 children had congenital cataract; 7 patients had traumatic cataract; in 5 cases there were secondary cataract: 3 children had cataract after uveitis, in 1 child cataract was due to steroid therapy because of nephrotic syndrome and 1 patient had neurodermatic cataract. In 16 cases PMMA lens was used, heparinized lens was implanted in 3 eyes and acrylic lens in 1 eye. The power of implants was from + 19 D to +24 D (mean 20.98 +/- 1.6 D). All measurements of axial length were obtained using ultrasound A scan. Examination was done from 14 months to 7.5 years after surgery (mean 3.5 +/- 1.55 years). The axial length in the operated eyes was compared with axial length of the fellow nonoperated eyes.
Mean axial length in operated eyes was 22.58 +/- 1.56 mm. Mean axial length in fellow eyes was 22.96 +/- 1.42 mm. There were no significant differences between operated and nonoperated eyes (p>0.05).
Cataract extraction with intraocular lens implantation does not influence rate of axial growth in children and adolescents.
评估接受单眼白内障摘除及人工晶状体植入术的儿童术后的眼轴长度。
在这项回顾性研究中，我们研究了20名年龄在7至20岁（平均14±3.65岁）的儿童，他们接受了单眼白内障手术：8名儿童患有先天性白内障；7名患者患有外伤性白内障；5例为继发性白内障：3名儿童在葡萄膜炎后出现白内障，1名儿童因肾病综合征接受类固醇治疗而导致白内障，1名患者患有神经性皮炎性白内障。16例使用了聚甲基丙烯酸甲酯（PMMA）晶状体，3只眼植入了肝素化晶状体，1只眼植入了丙烯酸晶状体。植入物的屈光度为+19 D至+24 D（平均20.98±1.6 D）。所有眼轴长度测量均使用A超进行。在术后14个月至7.5年（平均3.5±1.55年）进行检查。将手术眼的眼轴长度与未手术对侧眼的眼轴长度进行比较。
手术眼的平均眼轴长度为22.58±1.56 mm。对侧眼的平均眼轴长度为22.96±1.42 mm。手术眼与未手术眼之间无显著差异（p>0.05）。
白内障摘除及人工晶状体植入术不影响儿童和青少年的眼轴生长速度。
