“…However, variability in stereopsis measurements for multifocal lenses has been previously reported (15,20,21) . In this study, HCVA at near distances that were recorded with all lenses were lower than pre viously reported values (15,(20)(21)(22)(23)(24)(25) , which is primarily attributable to the difference in methodology. Unlike other studies, we sought to measure the smallest paragraph that patients could "comfortably" read, which involved an additional subjective element in the objective resolution task.…”

“…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.…”

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.

“…In terms of adaptation they found that subjective responses declined over the four days of contact lens wear. Fernandes et al also assessed adaptation of multifocal contact lenses and found that HCVA improved over 15 days of lens wear, though they did not assess changes in subjective vision responses [28]. The current study assessed visual performance within one hour of lens insertion.…”

“…The scientific literature shows good distance and near visual outcomes with simultaneous vision multifocal CLs [9][10][11][12][13][14][15][16][17][18]. However, some researchers have reported that prescribing rates of these CLs are low [19].…”
