Purpose
To determine the pass–fail rate of the PRESBYOND +1.50 D acceptance test, evaluate the incidence and age distribution of near-eye add titration, and quantify the frequency and nature of postoperative retreatments that modified the intended binocular target.
Setting
Private Practice Academic Unit Reinstein Vision, London Vision Clinic, EuroEyes Group, UK
Methods
This retrospective, non-comparative case series included 7,635 consecutive presbyopic patients (42–75 years) between Mar 2007 to Dec 2024. All patients underwent the PRESBYOND +1.50 D acceptance test. Patients who passed proceeded to PRESBYOND LASIK with near-eye add determined by titration from 1.50 D; those who failed underwent full distance correction. Binocular targets were categorised as Full Distance (Plano OU), Mini-blend (−0.25 to −1.25 D), or Standard Blend (≤−1.26 D). Targeting strategies were analysed across age groups. In PRESBYOND-treated patients, the incidence of target-modifying retreatments was calculated, categorised as (1) reversal of dominance, (2) reduction of add, or (3) conversion to full distance.
Results
Seventy-three patients (0.96%) failed the +1.50 D test and were targeted for full distance correction. Of the patients that passed, 969 (12.69%) were targeted for mini-blend, and 6,593 (86.35%) for standard blend. Full distance targeting was largely confined to patients aged 42–44 years (8.6%) and was ≤0.5% in older groups. Mini-blend incidence declined with age, with standard blend predominating from age 45 onward. Among PRESBYOND-treated patients (n=7,562), target-modifying retreatments were uncommon: reversal of dominance in 0.04%, reduction of add in 1.23% (mean reduction 0.28 ± 0.20 D), and conversion to full distance in 0.08%.
Conclusions
Full distance targeting was uncommon and primarily observed in younger presbyopic patients, whereas blended vision strategies predominated with increasing age. Postoperative modification of the intended binocular target was infrequent, with full reversal to distance correction occurring in a small proportion of cases.
