[Diplopia after intraocular lens implantation].

PURPOSE: Seven patients with diplopia after intraocular lens implantation were reported. Possible causes and prevention of diplopia were investigated preliminarily.

METHODS

Sixty successive cases, who had accepted uniocular cataract extraction and intraocular lens implantation, were followed-up. The kinds of diplopia, position of eyes, the movements of eyes, refrective state, pupil, fundus of eyes and the states of IOL were examined in all diplopia cases.

RESULTS

The incidence of diplopia in our cases was 11.67%. There was a close relationship between postoperative diplopia and preexistent strabismus, fusion disruption, myotoxic effects of local anesthetics, decentration of intraocular lens, macular disease and in identical opacity of posterior capsule.

CONCLUSION

Diplopia is a important complication after cataract extraction and intraocular lens implantation. Usually, it is difficult to deal with. It is helpful for decreasing diplopia to take corresponding methods according to possible causes.
