Comparison of Early Postoperative Visual Acuity Between Intracapsular and Supracapsular Phacoemulsification: A Randomized Controlled Clinical Trial

Exclusion Criteria

• •Considered unsuitable by the investigator for participation in this clinical trial for other reasons (e.g., unstable systemic condition, uncontrolled blood pressure/blood glucose, severe cardiovascular disease, renal disease, etc.)
• •Blood pressure \> 180/110 mmHg (systolic \>180 mmHg or diastolic \>110 mmHg). Patients may be considered for inclusion if blood pressure can be controlled below these thresholds with medication.
• •History of myocardial infarction or other cardiac disease requiring hospitalization, cerebral infarction, transient ischemic attack, or acute heart failure within 4 months prior to enrollment.
• •Women with childbearing potential (i.e., currently pregnant, breastfeeding, or planning to become pregnant within the next 2 years). Women of childbearing potential should be asked about the possibility of pregnancy, and the investigator will determine when a pregnancy test is necessary.
• •Currently participating in another clinical trial
• •History of ocular trauma or surgery
• •Presence of other ocular diseases (e.g., glaucoma, diabetic retinopathy)
• •Other ocular factors that may complicate surgery (e.g., small pupil, shallow anterior chamber)
