连续双眼白内障手术人工晶状体选择的进展

双眼白内障在短期内先后进行手术在临床上多见,但连续双眼白内障的手术时机以及是否需要根据第一眼的屈光误差来调整第二眼人工晶状体（IOL）的计算是眼科医师容易忽略的问题.尽管手术技术、IOL材料以及IOL计算公式的改进使手术前IOL度数预计与术后实际值之间的误差越来越小,但仍有5％的屈光误差大于±1D.利用第一眼的屈光误差值计算第二眼的IOL方法,通过第一眼的预测误差进行50％的调整可以明显的提高第二眼手术后的效果.同时,由于IOL植入术后1个月内屈光状态的变化,建议双眼手术时间最好间隔3～4周.这为临床中双眼连续白内障手术时机和IOL的选择提供了有利的指导.

Recent progress on study of the selection of intraocular lens in the bilateral sequential cataract surgery

Bilateral sequential cataract surgery is very common in clinical,but the ophthalmologists often ignore how to choose the timing of operation and whether the first eye can be used to improve the intraocular lens （IOL） power calculation for the second one.Despite the refinements in IOL selection with the use of third-generation IOL formulas,5% of eyes still result in a postoperative refractive surprise of ± 1.00 D or more.This paper introduced the methods of using refraction error of the first eye to improve the IOL power calculation for the second eye,and the refractive error of the second eye can be improved by modifying the IOL power to correct up to 50% of the error from the first eye in details.Because of the variation of the postoperative refractive surprise within a month,the interval of three to four weeks between two eyes cataract surgery is highly recommended.These conclusions may provide the advantageous guidance for us in the selection of IOL in bilateral cataract surgery.
