摘要
白内障术后由于人工晶状体(intraocular lens,IOL)原因导致的视力不提高甚至降低、眩光、散光加重等,需行包括IOL置换术在内的二次或多次手术,其中行IOL置换术的常见原因包括IOL脱位及半脱位、IOL屈光度误差、多焦点IOL神经适应性不佳等.手术方法包括取出原有IOL,将新IOL植入原位或应用多种方式进行缝合固定等.而在白内障患者围手术期做到术中稳定操作,撕囊大小适宜,提高术前生物学测量的准确性,优选屈光度计算公式等以避免IOL置换术的发生更为重要.(国际眼科纵览,2024,48:81-86)
Abstract
Following cataract surgery,factors related to the intraocular lens(IOL)may cause symp-toms such as failure to improve or even a decrease in visual acuity,glare,and increased astigmatism,which necessitate secondary or multiple surgeries including IOL exchange.The common causes of IOL exchange surgery include dislocation and subluxation,refractive error of the IOL,and neuroadaptation failure of multi-focal IOL.Surgical methods include removing the original IOL,implanting the new IOL in situ,or using va-rious suture fixation techniques.However,it is more important to avoid the occurrence of IOL exchange sur-gery by achieving stable operation,appropriate size of capsulorhexis,accurate preoperative biological meas-urements,suitable formula for calculating refractive power during the perioperative period of cataract patients.(Int Rev Ophthalmol,2024,48:81-86)
