Purpose
To report on the first results in cataract patients implanted with a non-diffractive, extended depth of focus (EDOF) IOL. The optical design utilises an increase of spherical aberration at the centre of the lens that gradually reduces at the margins. The theory is that this design enables an increased range of functional vision.
Setting
Midland Eye, Solihull
Methods
This is an ongoing, prospective case series of patients implanted bilaterally with this pre-loaded, non-diffractive EDOF IOL in a private clinic in Solihull, England. All patients underwent routine cataract removal using either phacoemulsification or femtosecond laser cataract surgery, followed by implantation of the IOL. All patients were targeted for emmetropia.
Results
To date, 92 eyes have been implanted with this IOL with the first patients achieving good uncorrected distance visual acuity (UCDVA) and an average 0.57 LogMAR uncorrected near visual acuity (UCNVA) at 1-month post-operative. In global, pooled results (N=206 eyes), patients achieved a mean UCDVDA of 0.132 LogMAR (Max = 0.65/Min = -0.1 LogMAR) and a mean UCNVA of 0.322 LogMAR (Max = 0.6/Min = 0.1 LogMAR).
Conclusions
The use of greater spherical aberrations at the centre of the optic appears to provide patients with a greater range of vision, compared to a standard monofocal IOL. In addition, our initial experience indicates that the diffractive-free design reduces patient visual complaints, including dysphotopsia. Although our experience is early, the design approach provides a high degree of patient satisfaction with good visual outcomes.
