Evaluation of Visual Outcomes and Patient Satisfaction with a Non-Apodized Diffractive Trifocal Intraocular Lens in Chinese Patients with Cataracts: A Prospective Multicenter Study
To assess clinical visual performance and patient-reported satisfaction following bilateral implantation of a non-apodized diffractive trifocal intraocular lens (IOL) in Chinese patients with cataracts.
Approach:
Patient Assessment: Secondary endpoints included best-corrected distance visual acuity, binocular defocus curves, refractive predictability, and patient-reported outcomes using Catquest-9SF and IOLSAT questionnaires.
Key Findings:
At 3 months, mean binocular UDVA, UIVA, and UNVA were 0.017 ± 0.086, 0.061 ± 0.110, and 0.061 ± 0.103 logMAR, respectively.
91.24% of patients achieved the composite endpoint of ≤0.200 logMAR binocularly at all three distances.
84.62% of eyes were within ±0.50 D of emmetropia.
96.90% of patients reported complete spectacle independence.
Interpretation:
Limitations:
The study excluded patients with ocular comorbidities that could affect visual outcomes.
The observational nature may limit generalizability.
