Abstract Details

Purpose:

To compare clinical and patient reported outcomes of 627 emmetropic presbyopic patients with different combinations of enhanced depth of focus (EDOF) and low add multifocal lenses.

Setting:

Optical Express, London, UK

Methods:

Outcomes of patients with bilateral implantation of multifocal IOLs were compared in patients with preoperative uncorrected distance visual acuity 20/25 or better in each eye. Three categories were included in analysis: Group A: bilateral Tecnis Symfony with micro monovision (273 patients), Group B: bilateral Tecnis ZKB00 multifocal diffractive IOL with +2.75 D near add (216 patients) and Group C: combination of Tecnis Symfony extended depth of focus IOL in dominant eye and Tecnis ZKB00 in non-dominant eye (138 patients). Three months postoperative clinical and patient reported outcomes were compared.

Results:

Groups A,B and C respectively achieved: Bilateral unaided distance visual acuity (UDVA) of ≥20/20 in 90.5%, 92.1% and 87.0% whereas bilateral unaided near visual acuity (UNVA) of ≥N6 in 85.0%, 93.1% and 87.7% of their patients. The percentage of patients that would recommend the procedure to their friends or family was 87.1%, 92.0 and 92.8% in groups A,B and C respectively. Preoperative to postoperative increase in glare (by more than 2 units on scale 1 to 7) was reported by 24.6% of patients in group A, 16.8% of patients in group B and 11.9% of patients in group C

Conclusions:

EDOF / Multifocal IOLs represent an effective treatment option for emmetropic presbyopes.  The bilateral Tecnis ZKB00 group achieved the best near visual acuity outcomes, while the combination of Tecnis Symfony in dominant eye and Tecnis ZKB00 in non-dominant eye had the lowest induction of glare. The increased glare induced in bilateral Tecnis Symfony group may likely be due to monovision effect.
