Bimanual微切口白内障摘除术的临床研究

Objective To study and explore the feasibility ofbimanual micro-incision cataract extrac-tion technology, and to evaluate it's clinical efficacy objectively. Methods Ultrasound energy, lime and emul-sified surgical astigmatism were observed in bimanual micro-incision phaeoemulsification group (A),and compared with conventional phacoemulsification group (B). Results The application of ultrasonic emulsifi-cation time and energy in group A: when nuclear hardness was degree Ⅱ, an average of 3.9 % energy was ap-plied,with an average time of the emulsion 0.56±0.40 rain; 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±0.82rain. The first day postoperative uncorrected visual acuity ≥ 0.5 accounted for 95.8%,≥1.0 accounted for 39.8%. There were no corneal incision bums, 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 inci-sion with technological superiority. This method has good clinical prospects.
