Pseudo-accommodation with intraocular lenses implanted in the bag.
OBJECTIVE
To evaluate the accommodation potential in eyes after intraocular lens in-the-bag implantation.


METHODS
Fifty-one consecutive patients were included in the study. Group 1 included 26 eyes that had phacoemulsification with continuous curvilinear capsulorhexis and in-the-bag implanted foldable IOL. Twenty-five eyes in Group 2 had capsulotomy with extracapsular cataract extraction and were implanted with polymethylmethacrylate IOL. Time elapsed from surgery was at least 6 months. There was no significant difference for age or gender between groups (P > .05). We measured accommodation amplitude and depth of the anterior chamber at distance and near fixation with an ultrasonic biometry device. The results were compared using the unpaired Student t-test.


RESULTS
The anterior chamber depths while fixating at a distant object were not significantly different between groups (P>.05), however, at near the difference was statistically significant (P=.008). The change in depths between far and near fixation was significantly different (P=.002) and was more pronounced in the the capsulorhexis group (P < .001). The accommodation amplitudes in this group were significantly greater than in the capsulotomy group (P = .025).


CONCLUSIONS
Patients who had uncomplicated small incision phacoemulsification surgery with continuous curvilinear capsulorhexis and in-the-bag implanted lens seemed to preserve some pseudo-accommodation after surgery.
