Interventions/Control_1

Patients with no ocular diseases other than cataract who are planned to have cataract surgery by one surgeon are selected for this study. In one eye, cataract surgery is performed during phacoemulsification and aspiration and intraocular lens 251 implantation by only 2.4mm incision. This surgical technique is one-handed technique.

Interventions/Control_2

Patients with no ocular diseases other than cataract who are planned to have cataract surgery by one surgeon are selected for this study. In the fellow eye, cataract surgery is performed during phacoemulsification and aspiration and intraocular lens implantation by 2.4mm incision and additional 0.9mm corneal side port. This surgical technique is two-handed technique.
