Summary
This study compared three AcrySof ReSTOR multifocal intraocular lenses (MIOLs), finding all provided good distance and near vision. Aspheric models showed reduced spherical aberration, with the +3.00 D model also improving intermediate vision.
Area of Science:
- Ophthalmology
- Biomedical Engineering
- Optics
Background:
- Evaluation of visual performance and wavefront error after multifocal intraocular lens (MIOL) implantation.
- Focus on three specific AcrySof ReSTOR MIOL models for comparative analysis.
Purpose of the Study:
- To assess and compare visual outcomes and optical aberrations following the implantation of three distinct AcrySof ReSTOR MIOLs.
- Investigate the impact of spherical versus aspheric designs and varying dioptric powers on visual function.
Main Methods:
- Prospective, comparative study over six months involving 60 eyes.
- Implantation of three diffractive AcrySof ReSTOR MIOLs: SN60D3 (+4.00 D spherical), SN6AD3 (+4.00 D aspheric), and SN6AD1 (+3.00 D aspheric).
- Assessment of distance visual acuity, distance-corrected near vision, distance-corrected intermediate vision, and ocular spherical aberration (RMS).
Main Results:
- Excellent distance visual acuity (≥0.1 logMAR) achieved in over 87.5% of eyes across all groups.
- No significant difference in distance-corrected near vision among the three MIOL groups (p = 0.822).
- Significant improvement in distance-corrected intermediate vision for the SN6AD1 (+3.00 D aspheric) group compared to others (p < 0.001).
- Significantly lower ocular spherical aberration (RMS) in aspheric MIOL groups (SN6AD3 and SN6AD1) versus the spherical MIOL group (SN60D3) (p = 0.048).
Conclusions:
- All evaluated diffractive AcrySof ReSTOR MIOLs effectively restore distance and near vision.
- The +3.00 D ReSTOR MIOL demonstrated efficacy in restoring intermediate vision.
- Aspheric ReSTOR MIOLs (+4.00 D and +3.00 D) significantly reduce induced spherical aberration compared to the spherical +4.00 D model.
