An observational study in Age-related Cataract, sponsored by Sakarya Yenikent State Hospital. Completed at 1 site in Turkey (Türkiye). Open to participants aged 45 Years and older. Per ClinicalTrials.gov, last updated 2026-04-23.
Sponsored by Sakarya Yenikent State Hospital · Observational
Consecutive comparative case series evaluating visual outcomes and patientreported satisfaction after bilateral cataract surgery with implantation of the same IOL type (standard monofocal, enhanced monofocal, or novel EDOF IOL). Outcomes assessed at 6 months included uncorrected visual acuity at distance, intermediate, and near; refraction; defocus curves; and questionnaires on halos, glare, and spectacle independence.
Patients undergoing bilateral phacoemulsification for age-related cataract received one of three IOLs in both eyes: Tecnis ZCB00 (monofocal), Tecnis Eyhance ICB00 (enhanced monofocal), or Asqelio EDOF ETLIO130C (EDOF). Follow-up examinations were performed at 1 day, 1 week, 1 month, 3 months, and 6 months. The 6-month assessment included monocular and binocular visual acuity at distance (6 m), intermediate (66 cm), and near (40 cm), manifest and objective refraction, binocular defocus curves (+1.00 D to -2.50 D in 0.50 D steps), and patient questionnaires (NEI-RQL-42 glare items; custom spectacle independence and satisfaction survey).

Visual Outcomes
* Binocular uncorrected distance visual acuity (UDVA) at 6 m, logMAR * Binocular uncorrected intermediate visual acuity (UIVA) at 66 cm, logMAR * Binocular uncorrected near visual acuity (UNVA) at 40 cm, logMAR
Time frame: 6 months
Patient satisfaction score
The patients were asked about their satisfaction with the refractive outcome, as used in International Multicenter Concerto Study as follows: How satisfied are you with your spectacle-free vision at far/intermediate/near distance? The answer choices ranged from 0 (not at all satisfied) to 10 (very satisfied).
Time frame: postoperative 6 months
Visual acuity
* Monocular UDVA, UIVA, UNVA (logMAR) * Monocular and binocular corrected visual acuity (CDVA, CIVA, CNVA) (logMAR)
Time frame: 6 months
Objective refraction
Manifest and objective refraction (spherical equivalent) (Diyoptri)
Time frame: 6 months
Defocus curve
Binocular defocus curve performance (+1.00 D to -2.50 D) (diyoptri)
Time frame: 6 months
Photic phenomena
Halo and glare scores (NEI-RQL-42 items 17 and 38; (0-100 scale)
Time frame: 6 months
