Comparison of objective accommodation in phakic and pseudophakic eyes between age groups
Graefe's Archive for Clinical and Experimental Ophthalmology Feb 02, 2019
Chung B, et al. - Authors estimated 83 candidates of age ≥ 40 years to compare objective accommodation of phakic and pseudophakic eyes between 2 different age groups. They categorized the candidates into following 4 groups: groups 1 (pseudophakic, age < 60 years), 2 (pseudophakic, ≥ 60 years), 3 (phakic, < 60 years), and 4 (phakic, ≥ 60 years). They observed the mean objective accommodation of 0.29 ± 0.47 D, 0.01 ± 0.21 D, 1.00 ± 0.88 D, and 0.01 ± 0.13 to a 2.0-D stimulus, and 0.26 ± 0.51 D, − 0.06 ± 0.21 D, 1.42 ± 1.21 D, and − 0.06 ± 0.21 to a 3.0-D stimulus in groups 1, 2, 3, and 4, respectively. They also noted the mean pupillary diameter of − 0.5 ± 0.8 mm, − 0.3 ± 0.8 mm, − 0.6 ± 0.5 mm, and − 0.6 ± 0.9 mm to a 2.0-D stimulus, and − 0.6 ± 0.8 mm, − 0.6 ± 0.8 mm, − 0.9 ± 0.5 mm, and − 1.0 ± 1.1 mm to a 3.0-D stimulus in groups 1, 2, 3, and 4, respectively. Overall, they found a correlation of age with objective accommodation among relatively young pseudophakic cases.
