To review the evidential basis of current practice in refractive lens exchange (RLE) vs. phakic intraocular lens (pIOL).
Visual outcomes after pIOLs are better than RLE. With RLE, there still remain risks of retinal detachment, cystoid macular oedema, glare, halos and posterior capsule opacification. With pIOLs, risks include pigment dispersion, cataract formation, glaucoma and inflammation. The decision to choose between either is broadly based on age and type of refractive error, and the choice follows thorough evaluation and counselling taking into consideration patient's needs and expectations.
With advancing technology, newer IOL models for RLE and phakic correction are becoming available. pIOLs provide better visual outcomes for distance correction and currently do not provide near-vision correction possible with RLE.
回顾折射性晶状体置换术（RLE）与有晶状体眼人工晶状体（pIOL）治疗的现有实践的证据基础。
pIOL 术后的视觉效果优于 RLE。RLE 仍存在视网膜脱离、黄斑囊样水肿、眩光、光晕和后囊混浊的风险。pIOL 相关风险包括色素播散、白内障形成、青光眼和炎症。选择 RLE 或 pIOL 的决定主要基于年龄和屈光不正的类型，并且在进行彻底的评估和咨询后，根据患者的需求和期望做出选择。
随着技术的进步，用于 RLE 和有晶状体眼矫正的新型 IOL 模型正在出现。pIOL 为远距离矫正提供了更好的视觉效果，而目前无法提供 RLE 可能实现的近视力矫正。
