**5.1 Intraocular energy delivered**

By using a laser to fragment the crystalline lens, less US energy is required to complete its removal. The reduction in the effective phako time can reach 70% and zero phacoemulsification time is possible in nearly 50% of operations [13].

Lower endothelial cell loss with the laser-assisted procedure compared with the manual phacoemulsification has been reported in the early post-operative state due to the reduction of EPT, with the LensX, the LensAR, the Catalys, and the Victus platforms [33].
