[The clinical study of stereopsis after bilateral intraocular lens implantation].

PURPOSE: To observe the stereopsis of senile cataract patients after bilateral intraocular lens (IOL) implantation.

METHOD: Subjects were divided into two groups: IOL group and normal group. Near stereoacuity with distance and near correction was checked with Randot steretests respectively. Near vision acuity was recorded with Logmar.

RESULT: Near stereoacuity with distance correction was (101 +/- 59)" and (112 +/- 55)" respectively, the responding near vision acuity was 0.51 +/- 0.15 and 0.52 +/- 0.17. Near stereoacuity with near correction was (33 +/- 11)" and (34 +/- l0)", the responding near vision acuity was 0.09 +/- 0.10 and 0.11 +/- 0.11. There was no significant difference in near stereoauity and near vision acuity between two groups (P > 0.05). Stereoauity and near vision acuity with near correction was significantly improved in both groups (P < 0.01).

CONCLUSION

Stereopsis after bilateral intraocular lens implantation was improved.
