Summary The anterior chamber intraocular lens (ACIOL) is the ideal intraocular lens (IOL) both for implantation during intracapsular cataract extraction and for secondary implantation. It is also useful during extracapsular cataract surgery, being especially indicated if there is a total absence of capsular support. ACIOLs are preferred over sulcus‐sutured IOLs because they are technically easier to implant, are reasonably well‐tolerated, and have a low rate of postoperative IOL decentration or tilt. However ACIOLs have also become one of the causes of IOL exchange and explantation. Implant‐related problems such as discrepancies between anterior chamber biometry and IOL size may cause pseudophakodonesis in the aqueous, resulting in progressive endothelial cell loss. Because of endothelial complications, they must be reserved for elderly patients. Infrequently, ACIOL‐iris contact may lead to pigment dispersion with subsequent inflammation. Occasionally, secondary angle closure and glaucoma with corneal decompensation due to haptic displacement may develop. Due to these reasons, eyes with shallow anterior chambers or early corneal guttata have been treated as relative contraindications for ACIOLs.
