Abstract:

The surgical techniques for phacoemulsification are becoming more and more abundant, mainly reflected in lens fragmentation such as phaco chop technique, stop-and-chop technique, etc. Pre-chop technique includes manual pre-chop and femtosecond laser-assisted pre-chop. This technology can significantly reduce the phacoemulsification time and energy, reduce the damage to the intraocular tissue of the surgery, shorten the operator's learning curve, and increase the surgical popularity. But there are still some problems that need to be solved in the complex cataract surgery now.
