Complications associated with rigid contact lenses are more frequent in aphakia. The limited dexterity of older patients not only may prove an insurmountable barrier to the mastery of daily contact lens insertion and removal, but also may produce significant direct eye trauma, its seriousness determined by the integrity of the cataract wound. Since prolonged wear of aphakic contact lenses is the rule rather than the exception, the risk of irreversible corneal changes such as vascularization and erosions is greater. A poorly fitted aphakic contact lens that does not permit adequate oxygenation of all corneal areas makes such complications even more likely to occur. Decreased corneal sensitivity associated with cataract surgery permits continued wear of a poorly fitted lens, which does not allow the cornea to recover between wearing periods. Detection of keratoconjunctivitis sicca, more prevalent in the older age group, may prevent the associated complications of corneal erosion, iritis, and infection. Complications of aphakic contact lenses can be controlled by patient instruction, appropriate contact lens adjustments, and regularly scheduled follow-up examinations.
无晶状体眼佩戴硬性隐形眼镜相关的并发症更为常见。老年患者灵活性有限，这不仅可能成为掌握日常隐形眼镜佩戴和摘取的不可逾越的障碍，还可能造成严重的直接眼部创伤，其严重程度取决于白内障伤口的完整性。由于无晶状体隐形眼镜长时间佩戴是常态而非例外，发生不可逆角膜变化（如血管化和糜烂）的风险更大。佩戴不合适的无晶状体隐形眼镜，无法使所有角膜区域获得充足的氧气供应，会使此类并发症更易发生。白内障手术导致角膜敏感性降低，使得佩戴不合适的隐形眼镜仍可继续，这会使角膜在佩戴周期之间无法恢复。在老年人群中更普遍的干眼症的检测，可预防角膜糜烂、虹膜炎和感染等相关并发症。无晶状体隐形眼镜的并发症可通过对患者的指导、适当调整隐形眼镜以及定期安排随访检查来控制。
