Objective?An experimental study was performed to explore the possibility of using a new absorbable synthetic material,the polylactic acid(PLA) as explants to avoid the complications caused by nonabsorbable explants,such as solid silicone.

• 目的研制可吸收性化学合成材料聚乳酸（polylacticacid，PLA）作为视网膜脱离手术填充物，以避免非吸收性合成材料引起的手术并发症。
