BACKGROUND
Cataract surgery with intraocular lens implant is, nowadays, the most frequent surgical procedure in all the world. Its success depends on a lot of factors, one of the most important is the calculation of the exact dioptric power of intraocular lens.
OBJECTIVE
To compare the calculation of dioptric power of intraocular lens with and without dilatation in patients with cataract.
MATERIAL AND METHODS
Longitudinal study, the calculation of the dioptric power of the intraocular lens was determined in patients without and with pupillary dilation. The variables were age, gender, eye to study, keratometry, axial length, anterior chamber depth and dioptric power of the intraocular lens. Descriptive statistics and Student t test were performed.
RESULTS
There were 37 patients, 23 females and 14 males. The average age was 68 + 7.87 years. Sixty-four eyes were studied, 30 were right and 34 left. Statistically, there was only significant difference in K2 of the ocular biometry between patients without and with pupillary dilation when obtaining a value of p < 0.05.
CONCLUSION
There are no changes in the calculation of the dioptric power of the Intraocular lens without and with pupillary dilation.
背景
如今，白内障超声乳化人工晶状体植入手术是全球最常见的外科手术。其成功取决于诸多因素，其中最重要的因素之一是准确计算人工晶状体的屈光度数。
目的
比较白内障患者散瞳与未散瞳情况下人工晶状体屈光度数的计算结果。
材料与方法
纵向研究，测定白内障患者未散瞳及散瞳情况下人工晶状体的屈光度数。变量包括年龄、性别、患眼、角膜曲率、眼轴长度、前房深度及人工晶状体屈光度数。进行描述性统计分析及学生t检验。
结果
共纳入37例患者，其中女性23例，男性14例。平均年龄为68±7.87岁。共研究64只眼，右眼30只，左眼34只。当p值<0.05时，经统计学分析，未散瞳与散瞳患者眼部生物测量中的K2值仅存在显著差异。
结论
散瞳与未散瞳情况下人工晶状体屈光度数的计算结果无差异。
