Inclusion criteria

Inclusion criteria: 1. Patients who plan to undergo phacoemulsification combined with intraocular lens implantation due to cataract; 2. The preoperative planning has been completed, and the intraocular lens is expected to be implanted with one of SN6CWS or SN6ATx; 3. Aged over 18 years old, regardless of gender; 4.
