Abstract Details

Purpose:

To examine and compare the magnitude of apparent accommodation in pseudophakic eyes with against-the-rule (ATR), with-the-rule (WTR), and minimum astigmatism. Factors associated with apparent accommodation were also examined in each group.

Setting:

University of Tsukuba Hospital

Methods:

Ninety-eight pseudophakic eyes (80 patients) with monofocal intraocular lens (IOL) implantation after uneventful cataract surgery were included. There were 41, 31, and 26 eyes with refractive ATR, WTR, and minimum (less than 0.5 diopters) astigmatism, respectively. Age, time after surgery, pupil size, corneal and refractive astigmatism, axial length, IOL power, corrected distance visual acuity, corneal multifocality, ocular wavefront aberrations, and apparent accommodation without cylindrical correction were evaluated and compared among the three groups.

Results:

No significant difference was found in the amount of apparent accommodation between groups. In the ATR group, the amount of apparent accommodation was significantly correlated with pupil size (r = -0.492, P ˂ 0.001) and refractive astigmatism (r = 0.509, P ˂ 0.001). In the WTR group, no clinical factors examined were significantly correlated with the amount of apparent accommodation. In the minimum astigmatism group, corneal multifocality was significantly associated with apparent accommodation (r = 0.409, P = 0.037).

Conclusions:

There was no significant difference in the average amount of apparent accommodation in pseudophakic eyes with ATR, WTR, and minimum astigmatism. However, the factors relevant to apparent accommodation were different depending on the status of postoperative refractive astigmatism.
