Abstract
Purpose: :
To examine visual outcomes following bilateral implantation of the FineVision trifocal intraocular lens (IOL; PhysIOL, Liège, Belgium).
Methods: :
Ten patients undergoing routine cataract surgery were implanted bilaterally with the FineVision Trifocal IOL and followed up post-operatively at 3 months. The FineVision optic features a combination of 2 diffractive structures, resulting in distance, intermediate (+1.75 D add) and near vision (+3.50 D add) zones. The unique design results in a light energy loss of just 14%. Apodization of the optic surface increases far vision dominance with pupil aperture. Data collected at the 3 month visit included uncorrected and corrected distance, intermediate and near vision; subjective refraction; defocus curve testing; contrast sensitivity; halometry glare testing and a questionnaire (NAVQ) to gauge near vision function and patient satisfaction.
Results: :
Mean post-operative UDVA was 0.14 ± 0.08 logMAR, with a mean spherical equivalent refraction of +0.43 ± 0.12 D. Mean CDVA was 0.01 ± 0.10 logMAR. Patients showed high levels of satisfaction with their unaided near vision (mean 3.5 ± 0.7, out of 5) and demonstrated good spectacle independence.
Conclusions: :
The FineVision IOL can reduce spectacle dependence following cataract surgery, and provide good patient satisfaction with uncorrected vision.
