[Clear lens exchange should be performed with caution].

Clear lens exchange (CLE) boasts a venerable lineage, its prominence in the field of ophthalmology having incrementally solidified over recent decades, concomitant with the evolution of surgical techniques and the innovation of intraocular lens materials. CLE has assumed a pivotal role in the therapeutic armamentarium for conditions such as glaucoma, high myopia, and presbyopia. Nevertheless, it remains that the sacrifice of accommodation, potentialities of intraoperative and postoperative complications, and less than optimal results in terms of spectacle independence resulting from CLE are not infrequent occurrences. The indiscriminate pursuit of this surgical intervention is inadvisable. It is only by means of a sagacious appreciation of the merits and demerits of CLE, the judicious circumscription of its indicatory ambit, and the bespoke selection of surgical modalities catering to the individual patient, that the superlative outcomes in the realms of surgical efficacy, safety, and patient contentment may be attained.透明晶状体置换术（CLE）具有悠久的历史。随着手术技术的不断进步和人工晶状体材料的发展，近年来逐渐在临床实践中得以广泛应用，尤其在青光眼、高度近视眼和老视等眼病治疗方面发挥了一定作用。然而，CLE所带来的调节功能的丧失、潜在的术中及术后并发症以及术后视力矫正的不理想等问题仍然存在，因此，不应盲目进行此类手术。唯有深刻理解CLE的利与弊，严格把握其适应证，并依据患者的个体情况选择手术方案，才能确保在手术效果、安全性和患者满意度等多个方面取得最佳结果。.
