Male and Female
1.Patients aged 40 to 90 years diagnosed with cataract who underwent phacoemulsification and intraocular lens implantation, gender is not restricted.
2.Patients with nuclear hardness graded up to 2 to 3 according to the Emery Little classification.
3. Patients in whom a monofocal intraocular lens or a toric intraocular lens was implanted.
1. Patients who underwent other ocular surgeries within one month after cataract surgery, or with a history of ocular surgery including shallow anterior chamber, uveitis, progressive diabetic retinopathy, corneal degeneration, corneal transplantation, or corneal refractive surgery.
2. Patients with corneal endothelial cell density less than 1500 cells/mm2.
3.Patients in whom the IOL could not be completely fixed within the capsular bag during surgery.
4. Patients deemed inappropriate by the investigator due to systemic or ocular comorbidities.

Postoperative assessments will be conducted at 1 day and 1 week after cataract surgery. Observations include total ultrasound time, cumulative dissipated energy (CDE), time from phaco tip insertion to removal, and central corneal thickness. Best corrected visual acuity and refraction will also be measured. All data will be collected from routine clinical examinations and surgical records without imposing additional burden on patients.
