Abstract
Along with the widespread application of intraocular lens (IOL) implantation in pediatric cataract patients, IOL-related complications may occur. Surgical reposition, explantation, or exchange of IOLs may become necessary when these complications pose a serious threat to visual functions. Because of the unique characteristics of pediatric eyes, greater postoperative inflammation, as well as possible adhesion of the IOL haptics to surrounding tissues after implantation, it is more complex and risky to explant than to implant IOLs. This chapter will discuss the surgical indications, preoperative preparation, selection of surgical approach, and surgical techniques for the reposition, explantation, or exchange of IOLs.
With the increased use of intraocular lens (IOL) implantation in cataract children, IOL-related complications also increase. When decentration or dislocation of IOL leads to significant visual loss or other complications, reposition, explantation, or exchange of the IOL may be necessary. Due to the unique ocular structure and severe postoperative inflammatory response in pediatric patients, adhesion between the IOL and its surrounding tissues is likely to occur, which increases the complexity and risk of IOL reposition and explantation. Thus, specific surgical methods or techniques may be required. This chapter elaborates on the techniques used in reposition, explantation, or exchange of an IOL.
