Recruiting

• Conditions: Age-related Cataract
• Interventions: Other: different types of intracular lens

• Registration Number: NCT04443101
• Lead Sponsor: Wenzhou Medical University

Brief Summary

Cataract patients were implanted with different types of intraocular lenses for grouping. SSOCT scanning was used to measure ELP and optometry.

Detailed Description

Cataract patients were implanted with different types of intraocular lenses for grouping. Perform SSOCT scan that was used to measure effective lens position and optometry at different postoperative follow-up time .
