Abstract
Purpose :
To compare visual performance of three commercial daily disposable multifocal soft contact lenses in presbyopes.
Methods :
Presbyopic participants (n=72, age range 40-73 years, myopes and hyperopes) wore 1-Day Acuvue Moist Multifocal (1DAMM), BioTrue ONEday for Presbyopia (BTOP) and Dailies AquaComfort Plus Multifocal (DACPM) for one week each in a double-masked, prospective, cross-over, randomized clinical trial. Lenses were fit as per manufacturers’ fitting guides. After one week, high- and low-contrast visual acuities (HCVA, LCVA) were measured at various distances between 6m and 40cm, and stereopsis at 40cm. Subjective performance was assessed on a 1-10 numeric rating scale for vision clarity, ghosting, driving vision, vision stability, ease of focusing, vision satisfaction and ocular comfort. Haloes at night and willingness to purchase the lenses were reported with categorical responses. Linear mixed models and chi-square tests were used for analysis and the level of significance was set at 5%.
Results :
BTOP provided significantly better HCVA and LCVA at distance compared to 1DAMM (1-2 letters, p≤0.026). Subjectively, 1DAMM was rated significantly lower than both BTOP and DACPM for distance clarity (7.5±2.0 vs 8.2±1.5 & 8.0±1.5, p≤0.049), distance ghosting (8.2±2.2 vs 8.8±1.7 & 8.8±1.6, p≤0.024), and driving vision (7.1±2.1 vs 7.7±1.6 & 7.6±1.6, p<0.001).
1DAMM provided significantly better HCVA at 70cm-40cm (1-3 letters, p≤0.010) and LCVA at 1m-40cm (1-4 letters, p≤0.004) compared to BTOP, and significantly better LCVA at 1m-50cm compared to DACPM (1-2 letters, p≤0.019). DACPM also provided significantly better HCVA and LCVA at 50cm and 40cm compared to BTOP (1-3 letters, p≤0.027). 1DAMM provided significantly better stereopsis than BTOP (66±59 vs 75±40 seconds of arc, p=0.017). Subjectively, BTOP was rated significantly lower than 1DAMM for intermediate clarity (7.1±1.8 vs 7.6±1.5, p=0.020) and near ghosting (6.8±2.7 vs 7.5±2.4, p=0.038), and significantly lower than both 1DAMM and DACPM for near clarity (5.9±2.2 vs 6.8±1.8 & 6.6±1.8, p≤0.007).
No other differences were found between lenses, including vision satisfaction and willingness to purchase lenses (p > 0.05).
Conclusions :
BTOP had better distance visual performance compared to near, while 1DAMM had the opposite effect. DACPM appeared to be an “all-purpose” lens, performing reasonably well at all distances.
