“…This study was limited by the small adaptation period. While this imitates what often occurs when patients first fit multifocal contact lenses in practice, changes in lens performance may occur over 4-15 days (9,22) . Longer term studies are required to determine if these study measures continue to predict performance over a longer period of time.…”

“…Papas et al pre viously reported that objective findings have little value for this purpose, and clinicians should rely on subjective findings to predict success (9) . We found that patients with better HCVA at intermediate, and occasionally near, distances tended to have higher satisfaction with overall vision, which in turn was a factor that influenced the patients' willingness to buy.…”

“…The high proportion of presbyopic contact lens wearers prescribed single vision or monovision lenses may be related to the practitioners' common perception that multifocal contact lenses are more challenging to fit to provide acceptable vision and/or the perceived visual performance by the contact lens wearers themselves (4) . Multifocal contact lenses, which use simultaneous imaging, often cause visual disturbances, such as ghosting and haloes, because the optical zones for intermediate-and near-distance focusing are positioned over the pupil (7)(8)(9)(10) . These disturbances can occur at any distance and are often exacerbated in low-contrast or low-illumination conditions.…”

Purpose: To compare visual acuity (VA), contrast sensitivity, stereopsis, and subjective visual performance of Acuvue® Oasys® for Presbyopia (AOP), Air Optix® Aqua Multifocal (AOMF), and Air Optix® Aqua Single Vision (AOSV) lenses in patients with presbyopia. Methods: A single-blinded crossover trial was conducted. Twenty patients with mild presbyopia (add ≤+1.25 D) and 22 with moderate/severe presbyopia (add ≥+1.50 D) who wore lenses bilaterally for 1 h, with a minimum overnight washout period between the use of each lens. Measurements included high-and low-contrast visual acuity (HCVA and LCVA, respectively) at a distance, contrast sensitivity (CS) at a distance, HCVA at intermediate (70 cm) and near (50 cm & 40 cm) distances, stereopsis, and subjective questionnaires regarding vision clarity, ghosting, overall vision satisfaction, and comfort. The test variables were compared among the lens types using repeated-measures ANOVA. Results: Distance variables (HCVA, LCVA, and CS) were significantly worse with multifocal lens than with AOSV lens (p≤0.008), except for AOMF lens in the mild presbyopia group in which no significant difference was observed (p>0.05). Multifocal lenses had significantly greater HCVA at 40 cm than AOSV lens (p≤0.026). AOMF lens had greater intermediate HCVA than AOP lens (p<0.03). AOP lens de monstrated greater improvements in stereopsis than AOMF and AOSV lens in the moderate/severe presbyopia group (p≤0.03). Few significant differences in subjective variables were observed, with no significant difference in the overall vision satisfaction observed between lens types (p>0.05). The proportions of patients willing to buy AOSV, AOMF, and AOP lenses were 20%, 40%, and 50%, respectively, in the mild presbyopia group and 14%, 32%, and 23%, respectively, in the moderate/severe presbyopia group; however, these differences were not sta tistically significant (p≥0.159). Conclusions: Further development of multifocal lenses is required before significant advantages of multifocal lenses over single vision lens are observed in pa tients with presbyopia.

“…Considering participant lifestyle, contact lens preference was not dependent on whether participants frequently drove, used a computer, cooked, shopped, used a mobile phone, watched Poor subjective visual satisfaction due to visual fluctuations, inadequate visual quality, halos and ghosting are commonly cited as reasons for presbyopic contact lens rejection [4,28]. Indeed, a trend emerged in the present investigation for some multifocal lens type preference to align with the lens offering the best distance visual acuity after 4 weeks of wear.…”

“…Indeed, data suggest it is unwise to rely on initial consulting room tests to predict the success of presbyopic contact lens options [3,4], at least for older designs. Therefore, the utility of additional indicators, clinical and/or non-clinical, to aid the initial selection of the optimum presbyopic lens would be beneficial, reducing the presbyopic contact lens drop-out rate and minimising chair time.…”

2 Abstract Purpose:To determine the utility of a range of clinical and non-clinical indicators to aid the initial selection of the optimum presbyopic contact lens. In addition, to assess whether lens preference was influenced by the visual performance compared to the other designs trialled (intrasubject) or compared to participants who preferred other designs (inter-subject). Methods:A double-masked randomised crossover trial of Air Optix Aqua multifocal, PureVision 2 for Presbyopia, Acuvue OASYS for Presbyopia, Biofinity multifocal and monovision was conducted on 35 presbyopes (54.3±6.2 years). Participant lifestyle, personality, pupil characteristics and aberrometry were assessed prior to lens fitting. After 4 weeks of wear, high and low contrast visual acuity (VA) under photopic and mesopic conditions, reading speed, Near Activity Visual Questionnaire (NAVQ) rating, subjective quality-of-vision scoring, defocus curves, stereopsis, halometry, aberrometry and ocular physiology were quantified. Results:After trialling all the lenses, preference was mixed (n=12 Biofinity, n=10 monovision, n=7 Purevision, n=4 Air Optix Aqua, n=2 Oasys). Lens preference was not dependent on personality Conclusions: Participant lifestyle and personality, ocular optics, contact lens visual performance and ocular physiology provided poor indicators of the preferred lens type after 4 weeks of wear. This is confounded by the wide range of task visual demands of presbyopes and the limited optical differences between current multifocal contact lens designs.
