Inclusion criteria
Inclusion criteria: 1. Patients aged 50 or older, diagnosed with bilateral age-related cataracts or bilateral senile cataracts, have surgical indications; 2. Have a postoperative desire to be free from glasses and meet the implantation indications for presbyopia-correcting IOLs; 3. During preoperative communication, patients understand the impact of astigmatism on the visual quality of presbyopia correction, are willing to choose the same or different types of presbyopia-correcting IOLs for both eyes, and accept the possibility of incomplete freedom from glasses or the need for IOL replacement surgery due to severe visual disturbances; 4. The IOLs implanted in both eyes are all from J&J, including mixed implantation of bilateral ZXR00 and ZMT, bilateral ZXR00 implantation, or bilateral ZMT implantation; 5. Postoperative follow-up time is 3 months or more, with available follow-up data beyond 3 months.
Exclusion criteria
Exclusion criteria: 1. Patients with severe or progressively worsening eye diseases (such as glaucoma, macular degeneration, diabetic retinopathy, optic neuropathy, etc.); 2.

Patients with severe photophobia not caused by cataracts; 4.
