Trabeculectomy for primary glaucoma was successfully combined with extracapsular lens extraction and insertion of a Pearce tripod posterior chamber lens in seven eyes of five patients. The results were similar to those expected from each component of the operation when performed alone, and all eyes achieved visual acuity of 6/9 or better with control of intraocular pressure below 22 mmHg without supplementary medical treatment. The incidence of mild anterior uveitis (three out of seven eyes) and hyphaema (two out of seven eyes) was greater than usual with this type of cataract extraction but no more than expected after trabeculectomy. Mydriatic drops may be used to treat postoperative iritis without danger to the stability of this pattern of implant. In addition the anterior chamber cannot become shallow, as the rigid legs of this lens extend behind the iris beyond the periphery of the cornea and prevent forward movement of the implant even if there is excessively free drainage of aqueous after the operation.
在5例患者的7只眼中，小梁切除术成功地与白内障囊外摘除术及Pearce三脚架后房型人工晶状体植入术联合进行。结果与单独进行手术的每个组成部分所预期的结果相似，所有术眼在未进行辅助药物治疗的情况下，眼压控制在22 mmHg以下，视力达到6/9或更好。与这种类型的白内障摘除术相比，轻度前葡萄膜炎（7只眼中有3只）和前房积血（7只眼中有2只）的发生率更高，但不超过小梁切除术后的预期。可使用散瞳滴眼液治疗术后虹膜炎，而不会对这种植入方式的稳定性造成危险。此外，前房不会变浅，因为这种人工晶状体的硬质襻延伸到虹膜后面，超出角膜边缘，即使术后房水过度引流，也能防止人工晶状体向前移动。
