Forty patients with aphakic bullous keratopathy undergoing combined penetrating keratoplasty and anterior vitrectomy using mechanical vitreous instruments were studied for a mean length of 36 months. Seventy percent of the grafts remained clear and thirty percent failed during the follow-up period. Fifty-three percent of those with clear grafts (15/28) obtained a visual acuity of 20/70 or better. In comparison to older methods of anterior vitrectomy, we have found that removal of vitreous with mechanical vitreous instruments offers more effective removal of solid and liquid vitreous, decreased surgical time, and decreased retinal traction. Further, it is easy to learn to use and handle these instruments.
对40例接受穿透性角膜移植术联合使用机械玻璃体器械进行前部玻璃体切割术的无晶状体大泡性角膜病变患者进行了平均36个月的研究。在随访期间，70%的移植片保持透明，30%失败。移植片透明的患者中有53%（15/28）视力达到20/70或更好。与较老的前部玻璃体切割术方法相比，我们发现使用机械玻璃体器械去除玻璃体能更有效地清除固体和液体玻璃体，缩短手术时间，并减少视网膜牵拉。此外，这些器械易于学习使用和操作。
