Abstract:
We compared the apparent accommodative power of 35 pseudophakic patients(43eyes) receiving posterior chamber lens in the bag with 34 normal persons(34eyes) by using AA-2000 accommodometer and evaluated the correlation between apparent accommodation and various factors like age, corrected visual acuity, refractive error, pupillary diameter, anterior chamber depth, or change of the anterior chamber depth in pseudophakic eyes. The mean apparent accommodative power was 1.41 +/- 0.62 diopter(D) in pseudophakic eyes and 1.58 +/- 1.71 D in phakic eyes and there was no stastistically significant difference between two groups. However, in cases younger than 55 years old, the apparent accommodative power was 1.34 +/- 0.48 D in 17 pseudophakic eyes and 2.51 +/- 2.31 D in 14 phakic eyes and there was statistically significant(p<0.05). Among the various factors, pupillary diameter appeared to be correlative to the apparent accommodative power in pseudophakic eyes. The smaller pupillary diameter, the greater accommodative power. Otherwise, another factors were not correlative to the apparent accommodative power.
