Eligibility

Sex/Gender
All

Inclusion criteria

Inclusion criteria: (1)Patients diagnosed with binocular cataract. (2)Patients who are planning to insert Clareon IOL or AcrySof IOL and have consent for IOL insertion. (3)Male and female patients aged 20 years or older when obtaining consent. (4)Patients who understand the explanation document and obtain written consent at their own will. (5)Patients who can visit for postoperative observation specified in the study protocol.

Exclusion criteria

Exclusion criteria: (1)Patients who are determined by the investigator to need astigmatism correction when obtaining consent. (2)Patients planning other eye surgery within 6 months after IOL insertion. (3)Patients with a history or complications of ophthalmic diseases that significantly affect visual function. (4)Patients with lenticular capsule or Zinn's zonular abnormalities that can induce deccentration or tilting of IOL. (pseudoexfoliation, etc.) (5)In addition, patients who are judged by the investigator to be inappropriate for the purpose of this study due to systemic or ophthalmic diseases.
