Objective:
To present the 6-month clinical results of the Z+ Virtual Aperture intraocular lens (IOL).
Approach:
- Study Design: A single-center study enrolled 43 patients (86 eyes) who received the Z+ IOL, including 38 eyes with the third-generation design.
- Data Presentation: Results were presented at the 44th Congress of the European Society of Cataract and Refractive Surgeons (ESCRS) by Dr. Francisco Sánchez León.
Key Findings:
- 100% of eyes with the third-generation lens achieved uncorrected distance vision of 20/32 or better in daylight conditions.
- 92% achieved uncorrected near vision of 20/32 or better.
- Mean uncorrected acuity was 20/25 at distance and 20/28 at near under mesopic conditions.
- All eyes reached best corrected distance vision of 20/25 or better.
- 79% of eyes read 20/40 or better at intermediate distance on a low-contrast chart.
- No serious adverse events reported; 100% free of halos, 79% reported no glare.
Interpretation:
The Z+ IOL provides a continuous range of vision from near to far without the adverse effects associated with multifocal lenses.
Limitations:
- Single-center study may limit generalizability.
- Further multicenter study results are pending and not yet available.
Conclusion:
The Z+ Virtual Aperture IOL demonstrates strong safety and effectiveness in providing multifocal visual acuity with monofocal clarity.
