Abstract:AIM： To observe the effect of manual chopping nucleus technique in phacoemulsification cataract surgery.METHODS: The manual chopping nucleus technique was performed in 132 cases (179 eyes) of age-related cataract with hard nucleus gradedⅢ,Ⅳ and Ⅴ before phacoemulsification. Male were 56 cases (82 eyes), female were 76 cases (97 eyes), the age was 53-74 (average 67.7±6.4) years. Subjects with lens dislocation, glaucoma and uveitis were exclused. Intraoperative phaco power and time, postoperative visual acuity and corneal edema were observed, and the follow-up were carried out for 1 week. RESULTS: Manual chopping nucleus technique before phacoemulsification reduced the release of ultrasound power. The low incidence of corneal edema was found postoperatively. CONCLUSION:Manual chopping nucleus technique was safe and effective in phacoemulsification cataract surgery.
