[An approach to the binocular vision of traumatic cataract after intraocular lens implantation].

OBJECTIVE

To explore the recovery of binocular vision and stereoacuity of monocular cataract extraction after posterior chamber intraocular lens (IOL) implantation.

METHODS

After extraction of traumatic cataract, primary or secondary posterior chamber IOL implantation was performed on 36 cases. The naked vision, corrected vision and binocular dioptric state were observed pre- and post-operatively. Synoptophore, Bogolini striated glasses, barred reading and Tiemus stereoscopic vision picture were applied.

RESULTS

The visual acuities of 36 cases were significantly improved postoperatively, the corrected visual acuities of 24 cases (66.7%) were over 4.95 and 30 cases were over 4.8 after three months. The binocular and stereoscopic vision of 21 cases was recovered well.

CONCLUSION

IOL implantation should be performed early after extraction of monocular cataract in order to improve the recovery and development of binocular vision and stereoacuity, particularly in children.
