Objetive To investigate the therapeutic effect and application value of the small incision non-phacoemulsification cataract surgery with IOL implantation via linear scleral tunnel incision in blindness prevention project, Methods In the cataract surgery of 90 cases (90 eyes) for blindness prevention project, linear scleral tunnel incision was made, followed by continuous circular capsulorhexis (CCC) or capsulotomy and hydrodissection. Nucleus was delivered with snare and cortex was absorbed. IOL was implanted into the capsular bag. The incision was left unstitched. Results 1 day postoperatively, the uncorrected visual acuity was ≥0.3 in 52 eyes (57.8%), between 0.05 and 0.3 in 29 eyes (32.2%), and ≤0.05 in 9 eyes (10%). 1 month postoperatively, the uncorrected visual acuity was ≥0.3 in 74 eyes (82.2%), between 0.05 and 0.3 in 11 eyes (12.2%), and ≤0.05 in 5 eyes (5.6%). 3 months postoperatively, the uncorrected visual acuity was ≥0.3 in 83 eyes (92.2%), between 0.05 and 0.3 in 6 eyes (6.7%), and ≤0.05 in 1 eye (1.1%). The corneal astigmatism was (1.30±0.47)D 1 month postoperatively and (0.82±0.52)D 3 months postoperatively. No significant difference was found (P>0.05) comparing to (0.8±0.64D) preoperative data. Conclusion The manual small incision cataract surgery with IOL implantation requires only simple devices and is easy to master, with lower surgery cost and reliable curative effect. It is suitable for the primary hospitals and is a practicable surgical approach.%目的：探讨经角膜缘后2mm“一字形”巩膜隧道切口行小切口非超声乳化+人工晶体植入术，在防盲中的治疗效果及应用价值。方法在开展防盲工作中90例（90眼）白内障手术,做“一字形”巩膜隧道小切口，连续环形撕囊或截囊,水分离，用圈套器脱出晶状体核，注吸皮质，囊袋内植入人工晶状体，切口不予缝合。结果术后第一天裸眼视力≥0.3者52眼(57.8％)，0.05-0.3者29眼(32.2％)，≤0.05者9眼(10％)。术后一月裸眼视力≥0.3者74眼(82.2％)，0.05-0.3者11眼(12.2％)，≤0.05者5眼(5.6％)。术后三个月时裸眼视力≥0.3者83眼(92.2％)，0.05-0.3者6眼(6.7％)，≤0.05者1眼(1.1％)。术后1个月角膜散光为(1.30±0.47)D，术后3个月角膜散光为(0.82±0.52)D，与术前比较（0.8.±0.64D）差异无统计学意义(P>0.05)。结论手法小切口自内障+人工晶体植入术，设备简单，易于掌握，手术费用低，疗效可靠。适合基层医院全面开展，是一种可行手术方式。
