[Apparent accommodation of the aphakic eye corrected by an artificial lens]

We measured apparent accommodation in 51 pseudophakic eyes (44 patients, after implantation of anterior (15 eyes) or posterior (36 eyes) intraocular lens. Glasses for distant vision were born during the test. The mean apparent accommodation was 1.89 +/- 0.91 dpt. 25 among these 51 pseudophakic eyes who were tested without their glasses showed a mean apparent accommodation that was not different in statistical and clinical terms. The mean accommodative power of 25 phakic and presbyopic eyes used as controls was 1.31 +/- 1.01 dpt. For these 51 pseudophakic eyes the correlation between apparent accommodation and the reciprocal of the pupillary diameter is the most significant (r = 0.79): the smaller the pupil, the greater the apparent accommodation. There was a negative correlation between apparent accommodation and anterior chamber depth (r = -0.64). No correlation was found between pseudo-accommodation and corrected visual acuity, corneal astigmatism and refractive error.
