Other related information

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.
