    Author: Zhu S, Wu X, Xu B.
    Journal: Zhonghua Yan Ke Za Zhi; 1998 Mar; 34(2):90-2. PubMed ID: 11877162.
    Abstract:
    OBJECTIVE: To investigate the technique of phacoemulsification for hard nucleus cataract extraction and evaluate its therapeutic effects. METHODS: Three methods of phacoemulsification, the improved divide and conquer, the reserve lens cortex spin and no lens cortex spin, were performed on 62 eyes according to the type of nucleus hardness. RESULTS: With foldable or 5.5 mm PMMA intraocular lens implantation, the improved divide and conquer phacoemulsification was performed on 26 eyes, the reserve lens cortex spin phacoemulsification on 23 eyes and no cortex spin phacoemulsification on 13 eyes. At postoperative 3 days, 5 days and 30 days, the visual acuities without correction 0.5 or better were obtained respectively in 46 eyes (74.2%), 60 eyes (96.8%) and 61 eyes (98.4%). The major complications were corneal edema and posterior capsular rupture. CONCLUSION: The technique of phacoemulsification for hard nucleus cataract is worthy to be spread due to safety, easiness and minimum complication.
