AIM: To evaluate the clinical effect of surgical treatment on monocular serious cataract with exotropia.

METHODS: Reviewed 45 patients diagnosed as cataract with exotropia who accepted cataract surgery and intraocular lens implantation from Mar. 2010 to Dec. 2012 in our hospital. Preoperatively the visual acuity of 44 patients was<0.05. One 2-year old child couldn't cooperate with the examination. The best-corrected visual acuity(BCVA), fundus, strabismus, binocular single vision(BSV)and diplopia condition were observed postoperative 6 months.

RESULTS: One 2-year old child couldn't cooperate with the examination. The other congenital cataract patient didn't acquire BSV and diplopia. Among 5 middle-aged patients, the BCVA of 3 cases were above 0.6 with normal fundus and BSV, 2 cases were finger count with abnormal fundus and without BSV. Among 38 senile cataract cases, 31 cases acquired BSV, 3 cases without BSV and diplopia, 3 cases appeared diplopia postoperatively and recovered in 6 months, 1 case with exotropia and diplopia accepted triple prism treatment.

CONCLUSION: Most of adult patients with monocular serious cataract andexotropia can acquire normal eye position and BSV.
