The causes and surgical methods of intraocular lens exchange
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)
