Age-related cataract
Conditions
Interventions
Experimental group:The experimental group was undergone Pentacam corneal spherical aberration measurement before surgery
the targeted range for residual total spherical aberration after surgery was set to 0 - 0.3 um
randomly assigned group:Randomly assigned patients were randomly implanted with an AO lens or a Tecnis ZA9003 lens.
