摘要

意图评估SRK II配方奶粉和校正因子Rm对有人工晶状体近视风险的先天性白内障儿童的临床疗效。材料和方法。对48名患有先天性白内障的儿童(86眼)进行了复杂的检查,包括视觉测量、眼压测量、眼压描记术、生物显微镜、角膜折射术、检眼镜、超声和厚度测量。为了确定IOL功率,我们使用了作者提出的SRK II公式,并补充了个人校正因子Rm。受试儿童被分为2组。主要组1包括22名患者(42眼),用Rm因子计算IOL度数。对照组2由26名患者(44眼)组成,根据传统的SRK II公式,使用与年龄相关的屈光度下校正来计算IOL度数,但没有Rm系数。后果校正因子Rm使我们能够在83.3%的主要组病例(与45.4%的对照组病例相比)中实现有发展为假晶状体近视风险的儿童的目标屈光,并将高年龄相关屈光的发展减少37.9%。在主要组的儿童中,视力平均达到0.5±0.001,而在对照组中,视力也更高,但仅达到0.200±0.001。结论根据公式:SRK II–R–Rm,计算涉及个人校正因子Rm的IOL光焦度的方法可推荐用于临床实践,重点关注有异常再折射风险的儿童。

Clinical efficacy of individual intraocular lens calculation in children with congenital cataract at risk of abnormal refraction
Purpose. To assess the clinical efficacy of the SRK II formula with a correction factor Rm in children with congenital cataracts who are at risk of pseudophakic myopia. Material and methods. A complex examination of 48 children (86 eyes) with congenital cataracts involved visometrics, tonometry, tonography, biomicroscopy, keratorefractometry, ophthalmoscopy, ultrasonography, and pachymetry. To determine the IOL power, we used the SRK II formula supplemented with the individual correction factor Rm, proposed by the authors. The examined children were divided into 2 groups. The main group 1 included 22 patients (42 eyes), for which the IOL power was calculated with the Rm factor. The control group 2 consisted of 26 patients (44 eyes) for which the IOL power was calculated according to the traditional SRK II formula using age-related hypocorrection of refraction but without the Rm coefficient. Results. The correction factor Rm, allowed us to achieve the targeted refraction in children who were at risk of developing pseudophakic myopia in 83.3 % of cases of the main group (versus 45.4 % of the control group cases) and reduce the development of high age-related refraction) by 37.9 %. In children of the main group, visual acuity reached, on average, 0.5 ± 0.001, while in the control group it was also higher but only reached 0.200 ± 0.001. Conclusion. The method of calculating the IOL optical power involving an individual correction factor Rm, according to the formula: SRK II – R – Rm can be recommended for clinical practice focused on children at risk of abnormal refractogenesis.
