IOL dislocation and opacification represent further complications of modern IOL (intraocular lenses) implantation. Currently, an increase of IOL dislocation due to various reasons is observed. Due to capsular bag shrinkage, especially in patients with pseudoexfoliation (PEX) and other ocular condition, there is an increasing tension of the weakened zonula. The only use of capsular tension ring (CRT) is not sufficient. The shrinkage of the capsular bag and increasing tension of the zonula may be reduced by additional anterior capsule incisions. The IOL should, preferably, be fixated retrogradely in cases of zonula weakness, even in the case of a weakened capsular bag or minor intraoperative zonulysis, to prevent later IOL dislocation. The effectiveness of these interventions should be examined in larger studies in the future.
人工晶状体脱位和混浊是现代人工晶状体植入术的进一步并发症。目前，观察到由于各种原因导致的人工晶状体脱位有所增加。由于囊袋收缩，尤其是在假性剥脱（PEX）患者和其他眼部疾病患者中，薄弱的悬韧带张力增加。仅使用囊袋张力环（CRT）是不够的。额外的前囊切开术可能会减少囊袋收缩和悬韧带张力增加。在悬韧带薄弱的情况下，即使囊袋薄弱或术中悬韧带轻度松解，人工晶状体最好逆行固定，以防止后期人工晶状体脱位。这些干预措施的有效性应在未来更大规模的研究中进行检验。
