· METHODS: The nuclei of 98 patients (98 eyes) were prechopped with a prechopper or two choppers and were divide into several sections before they underwent phacoemulsification with IOL implantation.

Supracapsular phacoemulsification with chopping nucleus technique;

Hard nucleus chopping technique in small-incision cataract surge-ry: two-knife plane chopping;

· AIM:To observe the effects of small incision extracapsular extraction by bow-knife chopping and intraocular lens(IOL)implantation in white cataract patients.

The application of two needles nucleus chopping in small incision extracapsular cataract extraction;

The clinical application of chopping nucleus with common instrument in small-incision surgery;

The clinical application of a developed lens loop and nuclear chopping instru-ment in small-incision nonphacoemulsifi-cation hard nucleus cataract surgery;

The observation of treatment for cataract performed by cool phacoemulsification and stop-and-chop skill;

Objective To evaluate the efficacy,indication,complication and announcements of the Hydrochop in cases with the soft-nucleus manual small incision cataract surgery(MSICS).
