Acquired lens colobomas secondary to ocular surgeries are scarcely described in the literature. We describe two cases of acquired lens coloboma in two infants with glaucoma who underwent ocular surgery. The coloboma in the first case was likely because of direct trauma to the lens zonules during an optical iridectomy with a vitrectomy cutter, resulting in localized loss of zonules and consequently localized lens coloboma. The coloboma in the second case was noticed during examination under anesthesia after scleral buckling and cryopexy for retinal detachment. The cause for coloboma development in this case could be disruption of the lens zonules because of stretching of the globe after scleral buckle surgery or because of injury to zonules during scleral buckling and the cryopexy procedure.
后天性晶状体裂孔继发于眼部手术在文献中鲜有描述。我们描述了两例接受眼部手术的青光眼婴儿的后天性晶状体裂孔。第一例晶状体裂孔可能是由于玻璃体切割器行光学虹膜切除术时直接损伤晶状体悬韧带，导致局部悬韧带丧失，从而导致局部晶状体裂孔。第二例晶状体裂孔是在巩膜扣带术和冷冻视网膜脱离复位术后全身麻醉检查时发现的。这种情况下晶状体裂孔的形成原因可能是巩膜扣带手术后眼球拉伸导致晶状体悬韧带断裂，也可能是巩膜扣带和冷冻过程中对悬韧带造成损伤。
