Penetrating Keratoplasty in high risk cases like paediatric patients, complicated cases of pseudophakic bullous keratopathy, or in patients with highly vascularized corneal opacities have been a challenge for opthalmologists because of the poor outcome. 101 patients with such high risk indications underwent penetrating keratoplasty. Some of them also underwent concurrent procedures like PC IOL implantation or vitrectomy. The patients' follow up period ranged from six months to four years. The results were evaluated. Good quality donor material, good intraoperative tissue handling, aggressive and meticulous postoperative management contributed to gratifying results. However chemical injuries and patients with dry eyes continued to have a bad prognosis and keratoplasty in these cases proved to be unrewarding.
对于儿科患者、人工晶状体植入术后大泡性角膜病变复杂病例或角膜混浊高度血管化的患者等高危病例，穿透性角膜移植术一直是眼科医生面临的挑战，因为预后较差。101例有此类高危指征的患者接受了穿透性角膜移植术。他们中的一些人还同时进行了如后房型人工晶状体植入或玻璃体切除术等手术。患者的随访期为6个月至4年。对结果进行了评估。优质的供体材料、良好的术中组织处理、积极细致的术后管理促成了令人满意的结果。然而，化学伤和干眼症患者的预后仍然很差，在这些病例中角膜移植术被证明是没有成效的。
