The suction trephine was studied in 31 aphakic and pseudophakic penetrating keratoplasty patients (31 eyes). The postoperative corneal astigmatism averaged 3.9 +/- 2.8 diopters overall. The 15 pseudophakic cases in nonscarred corneas showed a marked reduction in postoperative corneal astigmatism (3.59 diopters) when compared to previous reports. Our results have encouraged us to continue use of the suction trephine in all aphakic or combined keratoplasty procedures.
对31例无晶状体和人工晶状体穿透性角膜移植患者（31只眼）进行了抽吸环钻研究。术后角膜散光总体平均为3.9±2.8屈光度。15例人工晶状体植入且角膜无瘢痕的病例，与先前报道相比，术后角膜散光显著降低（3.59屈光度）。我们的研究结果促使我们在所有无晶状体或联合角膜移植手术中继续使用抽吸环钻。
