Abstract: 

Purpose: To compare three different methods for determining addition in presbyopes.
Methods: The study included 81 subjects with presbyopia who aged 40?70 years. Reading addition values were measured using 3 approaches including the amplitude of accommodation (AA), dynamic retinoscopy (DR), and increasing plus lens (IPL).
Results: IPL overestimated reading addition relative to other methods. Mean near addition obtained by AA, DR and IPL were 1.31, 1.68 and 1.77, respectively. Our results showed that IPL method could provide 20/20 vision at near in the majority of presbyopic subjects (63.4%).
Conclusion: The results were approximately the same for 3 methods and provided comparable ?nal addition, however, mean near additions were higher with increasing plus lens compared with the other two methods. In presbyopic individuals, increasing plus lens is recommended as the least time?consuming method with the range of ±0.50 diopter at the 40 cm working distance.
