    【摘要】目的评价M形切口白内障摘除人工晶体植入联合小梁切除术(三联手术)治疗青光眼合并白内障的安全性及有效性，并比较M形和超声乳化两种切口三联手术的临床疗效。方法按不同术式将40例(43只眼)拟行白内障摘除人工晶体植入联合小梁切除手术的患者，分为M形切口组25只眼和超声乳化组18只眼。术后随访15～37个月。结果术前平均眼压M组(25.3±9.8)mmHg，超声乳化组(25.7±9.5)mmHg，术后随访最终平均眼压M组(15.53±5.3)mmHg ，超声乳化组(15.01±3.2)mmHg。术后随访最终矫正视力范围0.1～1.2，2组≥0.5者分别为15只眼(60%)及12只眼(66%)，术后平均散光度M组(0.89±0.31)D，超声乳化组(0.78±0.5)D 。2组术后平均眼压下降、视力及散光度数均无显著性差异(P>0.05)。结论 M形小切口与超声乳化三联手术治疗青光眼合并白内障，均具有恢复有用视力、较好的降低眼压、并发症少等作用，2种术式结果则基本相同。

    【Abstract】 Objective To evaluate the therapeutic effects and safety of the combined Mincision cataract extraction, intraocular lens implantation and trabeculectomy (triple procedure) and compare the outcomes of the operation with two different small incision , M shape and phacoemulsification.Methods Forty patients (43 eyes) with coexisting glaucoma and cataract underwent triple procedure.Msmall incision approach was performed on 25 eyes, and phacoemulsification approach, on 18 eyes.The mean followup time was 15～37 months.Results The mean preoperative intraocular pressure (IOP) in M group was (25.3±9.8)mmHg (1 mmHg=0.133 kPa),phacoemulsification group was (25.7 ±9.5)mmHg.The mean postoperative IOP in the M group was (15.53±5.3) mmHg,phacoemulsification group was (15.01±3.2) mmHg.After operation,the visual acuities of the two groups were ≥0.5 in 15 eyes (60%) and in 12 eyes (66%) respectively,The mean magnitude of astigmatism was( 0.89±0.31)D in M group,and (0.78±0.5) D in phacoemulisification group.There were no statistical differences for the postoperative outcomes of IOP,visual acuity, astigmatism and filtering bleb between two groups (P>0.05).Conclusion M smallincision combined with phacoemulsification triple operation is effective in treating patients with glaucoma complicated with cataract,improving the visual acuity rapidly and reducing intraocular pressure,with less postoperative complications. ......
