Thirty-five secondary and six primary 'baseball' implants--acrylic balls in envelopes of donor sclera--were followed up for a minimum of 24 months. 97.1% secondary and 50% primary implants were retained. Volume replacement was satisfactory in 83.8% with a single operation, and motility of the artificial eye was at least 14 degrees of horizontal gaze in 86%, at least 7 degrees of upgaze in 95%, and at least 14 degrees of downgaze in 62.6%. Ptosis associated with the procedure occurred in 22%, and 12.2% developed a shallow fornix with instability of the artificial eye.
对35个二期和6个一期“棒球”植入物（丙烯酸球置于供体巩膜囊中）进行了至少24个月的随访。二期植入物的保留率为97.1%，一期植入物的保留率为50%。83.8%的患者通过单次手术实现了满意的容量置换，86%的患者假眼水平注视运动至少为14度，95%的患者上视运动至少为7度，62.6%的患者下视运动至少为14度。该手术相关的上睑下垂发生率为22%，12.2%的患者出现穹窿变浅和假眼不稳定。
