What are the advantages of Alcon PanOptix Trifocal IOL compared with traditional IOL?

The traditional cataract IOL, monofocal lens can only see near or far, most people will choose to see far when using monofocal lens, so they still need to wear presbyopia when reading newspaper after surgery; bifocal lens can see near and far, which is more convenient than the monofocal lens, but it lacks the mid-range vision, for example, if you are playing tennis, you can see the opponent serving the ball with the multifocal lens, but you can find the ball flying in front of you at the next instant, but you cannot see the route of the ball running after it is sent out clearly, which is the lack of the mid-range vision. For example, in tennis, a multifocal lens can see the opponent's serve, but in the next moment it can see the ball flying in front of you, but not the route of the ball after it is sent out. The Alcon PanOptix Trifocal IOL provides very clear vision at mid-distance (60 cm), covering the range that a bifocal lens cannot reach.
