Current patterns of practice relating to primary intraocular lens (IOL) implantation in children < or =2 years old in the UK and Ireland are investigated.
National postal questionnaire surveys of consultant ophthalmologists in the UK and Ireland.
76% of 928 surveyed ophthalmologists replied. 47 (7%) of the respondents operated on children aged < or =2 with cataract. 41 (87%) of respondents performed primary IOL implantation, but 25% would not implant an IOL in a child under 1 year old. 88% of surgeons used limbal wounds, 80% manual capsulotomies, 98% posterior capsulotomies and 100% hydrophobic acrylic lenses. The SRK/T formula was most commonly used (70%). Exclusion criteria for primary IOL implantation varied considerably and included microphthalmos (64% of respondents), anterior and posterior segment anomalies (53%, 58%), and glaucoma (19%).
Primary IOL implantation in children < or =2 has been widely adopted in the UK and Ireland. There is concordance of practice with regards to surgical technique and choice of IOL model. However, there is some variation in eligibility criteria for primary IOLs: this may reflect a lack of consensus on which children are most likely to benefit. Thus, there is a need for systematic studies of the outcomes of primary IOL implantation in younger children.
对英国和爱尔兰2岁及以下儿童一期人工晶状体（IOL）植入的当前实践模式进行了调查。
对英国和爱尔兰的眼科顾问医生进行全国邮政问卷调查。
928名接受调查的眼科医生中有76%回复。47名（7%）受访者为2岁及以下患有白内障的儿童实施了手术。41名（87%）受访者进行了一期IOL植入，但25%的受访者不会为1岁以下儿童植入IOL。88%的外科医生采用角膜缘切口，80%采用手法截囊，98%采用后囊切开，100%采用疏水性丙烯酸晶状体。最常使用的是SRK/T公式（70%）。一期IOL植入的排除标准差异很大，包括小眼球（64%的受访者）、眼前段和眼后段异常（53%、58%）以及青光眼（19%）。
在英国和爱尔兰，2岁及以下儿童的一期IOL植入已被广泛采用。在手术技术和IOL型号选择方面存在实践一致性。然而，一期IOL的适用标准存在一些差异：这可能反映出对于哪些儿童最可能受益缺乏共识。因此，需要对年幼儿童一期IOL植入的结果进行系统研究。
