The use of the Kelly Descemet's membrane punch enables the glaucoma surgeon to perform smaller trabeculectomies. The outcome of 'microtrabeculectomy' employing a 2 x 2 mm superficial scleral flap and a 0.75 mm internal osteum was evaluated on 65 eyes of 50 patients (mean age 70 years). The operation site was nasal in left eyes and temporal in right eyes. In the 56 eyes where 5-fluorouracil was not used, the mean intraocular pressure (IOP) on diagnosis was 33.4 mmHg, the mean pre-operative IOP being 25.1 mmHg. After a mean follow-up of 13.4 months (minimum 3 months) following surgery, the mean IOP was 13.4 mmHg with 88% of eyes controlled at < 21 mmHg on no medications. Nasally sited microtrabeculectomies resulted in lower IOPs than temporally sited procedures (11.8 vs 14.9 mmHg, p = 0.003) at last follow-up visit.
使用凯利后弹力层穿刺器可使青光眼手术医生实施更小的小梁切除术。对50例患者（平均年龄70岁）的65只眼睛采用2×2毫米浅层巩膜瓣和0.75毫米内口进行“微型小梁切除术”的效果进行了评估。手术部位左眼在鼻侧，右眼在颞侧。在未使用5-氟尿嘧啶的56只眼中，诊断时平均眼压（IOP）为33.4毫米汞柱，术前平均眼压为25.1毫米汞柱。术后平均随访13.4个月（最短3个月），平均眼压为13.4毫米汞柱，88%的眼睛在未使用药物的情况下眼压控制在<21毫米汞柱。在最后一次随访时，鼻侧微型小梁切除术的眼压低于颞侧手术（11.8对14.9毫米汞柱，p = 0.003）。
