目的：评价超声乳化白内障吸除联合人工晶状体植入术对伴有知觉性外斜视的白内障患者的疗效。 方法：通过前瞻性研究观察伴有知觉性外斜视的白内障患者79例，行超声乳化白内障吸除联合人工晶状体植入术。于术前、术后1,3mo观察其视力、眼位、双眼视功能及复视情况。并对眼位改善情况、复视情况与引起知觉性斜视的原因做相关分析。 结果：术后随访3mo，术后1mo最佳矫正视力≥0.3的有48例，其中≥0.5的有31例，≤0.02有8例。53例患者术后1～3mo外斜眼位均已自发纠正，且获得不同程度双眼视功能恢复。术后3mo，30例患者复视消失。单纯由白内障所致的知觉性斜视患者术后视力、眼位及复视均改善优于其他眼病所致的白内障患者。 结论：对于伴有知觉性斜视的白内障患者作相应的治疗，斜视程度可以得到一定的改善。

AIM: To evaluate the efficacy of surgical treatment of cataract with sensory exotropia. METHODS: In a prospective, consecutive clinical trail, 79 cases who had cataract with sensory exotropia accepted phacoemulcifiation and intraocular lens(IOL) implantation. The best-corrected visual acuity(BCVA), eye position, binocular visual function and diplopia condition were observed preopetatively and postoperative 1 month, 3 months. Correlation analysis was done on eye position improvement, diplopia and causes for sensory exotropia. RESULTS: BCVA of 48 cases were above 0.3, 31 cases above 0.5 and only 8 cases below 0.02 at 1 month postoperatively. 53 cases had normal eye position and acquired different degree of binocular function 1 to 3 months after operation. Diplopia of 30 cases disappeared at 3 months postoperatively. Patients with sensory exotroia due to cataract simply had more improvement in BCVA, eye position and binocular function than those due to other diseases. CONCLUSION:Patients who have cataract with sensory exotropia should accept surgical treatment of cataract first. The eye position and binocular function can be improved after operation.
