A retrospective review was undertaken to compare outcomes in 26 eyes that underwent penetrating keratoplasty (PKP) and drainage tube surgery (Molteno double-plate implant or Schocket procedure). Drainage tube surgery was performed either before PKP (10 eyes), after PKP (7 eyes), or at the same time as PKP (9 eyes). Mean follow up was 22 months. The average preoperative intraocular pressure (IOP) for all of the eyes was 31 mm Hg; 96% of them achieved a final IOP of less than 18 mm Hg (average, 14 mm Hg on a mean of 0.8 medications). Graft failure occurred in 11/26 (42%). Eight of these eyes were regrafted, and six of these eight have remained clear at a mean follow up of 22 months after regrafting. The overall PKP success rate, including the eyes that underwent repeat PKP, was 81%. Visual acuity remained stable or improved in 70% of the eyes.
进行了一项回顾性研究，以比较26只接受穿透性角膜移植术（PKP）和引流管手术（莫尔滕诺双板植入术或肖基特手术）的眼睛的治疗结果。引流管手术在PKP之前进行（10只眼）、PKP之后进行（7只眼）或与PKP同时进行（9只眼）。平均随访时间为22个月。所有眼睛术前平均眼压（IOP）为31 mmHg；其中96%的眼睛最终眼压降至18 mmHg以下（平均为14 mmHg，平均使用0.8种药物）。26只眼中有11只（42%）发生植片失败。其中8只眼再次进行了角膜移植，这8只眼中有6只在再次移植后平均随访22个月时植片保持透明。包括接受再次PKP的眼睛在内，总体PKP成功率为81%。70%的眼睛视力保持稳定或提高。
