摘　　要：目的对Bimanual微切口白内障摘除技术及可行性进行研究和探讨，客观评价其临床疗效。方法对Bimanual（双手操作）微切口超声乳化（A组），观察超声能量、乳化时间和术后散光，并与常规超声乳化手术（B组）进行比较。结果A组超声能量和乳化时间：核硬度为Ⅱ级者平均应用能量3．9％、平均乳化时间为（0．56±0．40）min；Ⅲ级核者平均应用能量8．3％、平均乳化时间为（0．65±0．58）；Ⅳ级核者平均应用能量12％、平均乳化时间为（1．35±0．82）min。术后首日裸眼视力t〉0．5者占95．8％，≥1．0者占39．8％。无角膜切口灼伤、切口漏液、前房异常等并发症。术后7d：A组平均手术性散光为（0．42±0．55）D，B组平均手术性散光（1．26±1．14）D，术后3个月：A组平均手术性散光为（0．35±0．25）D，B组平均手术性散光（0．87±0．62）D，两组散光变化差异均有统计学意义。结论Bimanual微切口超声乳化白内障摘除手术具有稳定良好的临床疗效，具有切口微小等技术优势，具有很好的临床前景。Objective To study and explore the feasibility ofbimanual micro-incision cataract extraction technology, and to evaluate it＇ s clinical efficacy objectively. Methods Ultrasound energy, time and emulsified surgical astigmatism were observed in bimanual micro-incision phacoemulsification group （A）, and compared with conventional phacoemulsification group （B）. Results The application of ultrasonic emulsification time and energy in group A： when nuclear hardness was degree Ⅱ, an average of 3.9 % energy was applied, with an average time of the emulsion 0.56±0.40 min; when nuclear hardness was degree Ⅲ, an average of 8.3 % energy was applied,with an average time for the emulsification 0.65±0.58; when nuclear hardness was degree Ⅳ, an average of 12% energy was applied, with an average time of emulsion 1.35±0.82min. The first day postoperative uncorrected visual acuity≥0.5 accounted for 95.8%,≥1.0 accounted for 39.8%. There were no corneal incision burns, incision leakage, anterior chamber abnormalities and other complications. After 7 days of operation, an average of astigmatism surgery was 0.42±0.55D in group A, 1.26±1.14 in group B, after 3 months of operation, an average of astigmatism surgery was 0.35 ±0.25D in group A,0.87±0.62 in group B. The changes of astigmatism in the two groups were statistically significant. Conclusion Bimanual micro-incision in phacoemulsification cataract surgery possesses good clinical efficacy, stability, and small incision with technological superiority. This method has good clinical prospects.
