To compare objective accommodation of phakic and pseudophakic eyes between two different age groups.
Eighty-three eyes (83 participants aged ≥ 40 years) with a visual acuity of 20/25 or better, and refractive error < spherical - 1.0 diopters (D) and cylindrical 1.0 D, were included. Forty-four patients had undergone phacoemulsification and monofocal intraocular lens implantation and were examined 6 months post-surgery. Participants were divided into groups 1 (pseudophakic, age < 60 years), 2 (pseudophakic, ≥ 60 years), 3 (phakic, < 60 years), and 4 (phakic, ≥ 60 years). Objective accommodation and pupil diameter to 2.0- and 3.0-D stimuli were measured with a binocular open-field autorefractor.
The mean objective accommodation was 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. For both stimuli, the values in group 1 exceeded those in groups 2 and 4, and were smaller than those in group 3, while the values in group 3 exceeded those in groups 2 and 4. The mean pupillary diameter was - 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. There was significant correlation between objective accommodation and changes of pupil size for both stimuli.
Age seems to play a role in objective accommodation among relatively young pseudophakic patients.
比较两个不同年龄组有晶状体眼和人工晶状体眼的客观调节功能。
纳入83只眼（83名年龄≥40岁的参与者），其视力为20/25或更好，屈光不正<球镜-1.0屈光度（D）且柱镜1.0D。44例患者接受了白内障超声乳化吸除联合单焦点人工晶状体植入术，并在术后6个月进行检查。参与者被分为1组（人工晶状体眼，年龄<60岁）、2组（人工晶状体眼，≥60岁）、3组（有晶状体眼，<60岁）和4组（有晶状体眼，≥60岁）。使用双目开放视野自动验光仪测量对2.0D和3.0D刺激的客观调节和瞳孔直径。
对于2.0D刺激，1组、2组、3组和4组的平均客观调节分别为0.29±0.47D、0.01±0.21D、1.00±0.88D和0.01±0.13D；对于3.0D刺激，分别为0.26±0.51D、-0.06±0.21D、1.42±1.21D和-0.06±0.21D。对于两种刺激，1组的值均超过2组和4组，且小于3组，而3组的值超过2组和4组。对于2.0D刺激，1组、2组、3组和4组的平均瞳孔直径分别为-0.5±0.8mm、-0.3±0.8mm、-0.6±0.5mm和-0.6±0.9mm；对于3.0D刺激，分别为-0.6±0.8mm、-0.6±0.8mm、-0.9±0.5mm和-1.0±1.1mm。两种刺激下的客观调节与瞳孔大小变化之间均存在显著相关性。
年龄似乎在相对年轻的人工晶状体眼患者的客观调节中起作用。
