Inclusion criteria
Inclusion criteria: 1. Age between 45 and 80 years old. 2. At least 40% of age-related cataract patients with LOCS III grade >= 3 in one eye are planning to undergo cataract surgery and have both eyes implanted with Clareon PanOptix Pro intraocular lens/Clareon PanOptix Pro astigmatism correcting intraocular lens or Clareon single focus/Clareon astigmatism correcting intraocular lens (maximum 40% of patients), with the goal of developing an emmetropic eye. 3. For eyes with preoperative regular corneal astigmatism= 0.75D and suitable for implantation of Clareon PanOptix astigmatism correction/Clareon single focus astigmatism correction T3-T6 intraocular lenses, Clareon PanOptix Pro astigmatism correction/Clareon single focus astigmatism correction intraocular lenses will be implanted. According to the Barrett astigmatism calculator, the predicted residual astigmatism should be <= 0.50D. 5. The researchers determined that the potential postoperative visual acuity of each eye could reach 20/25 or better. 6. I have signed the informed consent form for research participation and agree to comply with all research procedures. 7. Able to understand and sign informed consent forms approved by the ethics committee. 8. Willing and able to participate in all planned research visits as required by the plan.
Exclusion criteria
Exclusion criteria: 1. There are any systemic diseases or eye conditions (such as amblyopia, glaucoma, corneal disease, uveitis, macular degeneration or retinopathy, neuro ophthalmic diseases, etc.) that are expected to affect surgical efficiency or potential postoperative vision, irregular astigmatism, iris abnormalities, suspensory ligament instability, polar cataracts, or other conditions that researchers believe should be excluded. 2. Patients planning to undergo femtosecond laser assisted cataract surgery (FLACS). 3. Patients with any history of eye surgery, eye trauma, eye inflammation, or laser treatment (such as fundus laser photocoagulation). 4. Patients who experience intraoperative or postoperative complications.
