[To observe clinical effect of accommodative IOL on different age patients]

To observe clinical effect of accommodative IOL on different age patients.

Retrospective case series of fifty-four patients implanted with accommodative IOL were divided into three groups according to their age: 39-60, 60-75 and older than 75 years. Three months after the cataract surgery, distant visual acuity, near visual acuity and defocusing with minus glasses (D) were examined and depth of anterior chamber was measured by ultrasound biomicroscope.

There were no statistically significant differences in distant visual acuity among these three groups. Near visual acuity in older than 75 group was significantly lower than the other two groups. There were no statistically significant differences in the depth of anterior chamber among these three groups. When patients watched the target moving from 5 meters away to near, the change of depth of anterior chamber in older than 75 group was significantly less than that in the other two groups. Accommodation power in older than 75 group was significantly lower than that in the other two groups as measured by defocusing with minus glass (D).

Patients implanted with accommodative IOL can get good distant and near visual acuities. Younger patients may obtain more benefit from accommodative IOL such as obtaining higher accommodative power.
