[Accommodation in pseudophakic eyes with monofocal posterior chamber intraocular lens].
OBJECTIVE
To study the accommodative problem of pseudophakic eyes with commonly implanted monofocal posterior chamber intraocular lens (PC-IOL).


METHODS
Slataper's method, dynamic retinoscopy and pattern-visual evoked potentials were used to measure the accommodative power in 120 pseudophakic eyes (101 patients) with monofocal PC-IOL.


RESULTS
The mean accommodative power was 2.15 +/- 0.76 D. Stepwise regression analyses revealed that the apparent accommodation is positively correlated with the corrected distant vision and the distantly corrected near vision, respectively.


CONCLUSIONS
The apparent accommodation of pseudophakic eyes does exist, but it is a false one. The result of accommodative power measured by dynamic retinoscopy is the most objective and precise. The central visual efficiency and the applicable range of accommodation in pseudophakic eyes with low myopia (-1.00 D) are better than that in emmetropic pseudophakic eyes.
