[Stereopsis of the patients after cataract extraction and intraocular lens implantation].
OBJECTIVE
To understand the stereopsis of the patients after cataract extractation and intraocular lens implantation and the related factors.


METHODS
In this study were examined the stereopsis of 30 patients who had undergone cataract extraction and intraocular lens implantation and whose post-operative vision acuity measurements were 0.5 or higher.


RESULTS
These patients' steroacuity, anisometropia, aniseikonia and scotoma were: 407.67" +/- 390.19", 1.53D +/- 1.96D, 3.93% +/- 3.51%, 3.17" +/- 1.98" respectively. There was no significant correlation between steroacuity anisometropia and aniseikonia. There was siganificant positive correlation between steroacuity and scotoma.


CONCLUSIONS
Intraocular lens implantation may ameliorate anisometropia and aniseikonia of the patients after cataract extraction and reduce the damage to stereopsis.
