摘　　要：目的观察超声乳化白内障吸除联合负度数人工晶状体植入术治疗白内障合并超高度近视的临床疗效。方法对15例(26眼)白内障合并超高度近视眼患者,施行超声乳化白内障吸除联合负度数人工晶状体植入术,记录术前矫正视力、眼轴长度、屈光度数及其与预期屈光度数的偏差值,观察手术并发症和术后眼部情况。结果术前眼轴长度30.12～35.76mm,平均为32.45mm。术中均顺利植入人工晶状体,无后囊破裂发生。植入屈光度数为-1.0～-6.0D,术后1周,24眼视力均有不同程度的提高,最佳矫正视力≥0.2共20眼(76.9%),其中≥0.5者共8眼(30.77%)。2眼因严重的黄斑区网膜萎缩变性,视力无明显提高。术后屈光度数偏差值<±2.00D共22眼(84.6%),<±1.00D共14眼(53.8%)。随访时间为3～24个月。后囊膜皱褶6眼,后发性白内障7眼,5眼行激光后囊膜切开术,无视网膜和脉络膜脱离发生,无眼压升高。4例单眼白内障患者中,1例出现双眼干扰症状。结论超声乳化白内障吸除联合负度数人工晶状体植入既可以进行屈光矫正,又可以增加眼内组织的稳定性,减少视网膜脱离的发生,是治疗白内障合并超高度近视眼安全、有效的方法。Objective To observe the clinical significance of phacoemulsification and implantation of negative-power posterior chamber intraocular lenses （IOL） in patients with super high myopia and cataract. Methods 15 cases （26 eyes） with super high myopic cataract were performed with phacoemulsification and negative intraocular lens implantation. Their preoperative corrected vision, axial length,postoperafive visual acuity, refractive status, refractive error and complications were observed. Patients were followerd 3 to 24 months. Results The mean preoperative axial length was 30.12-35.76 mm. Lens with diopter （D）of-1.00 -6.00D were implanted. Postoperative corrected visual acuity achieved 0.2 or better in 20 eyes（76.9%）, 0.5 or better in 8 eyes （30.77%）. Refractive error within 2.00D were in 22 eyes（84.6%）, among them 14 eyes （53.8%） were within an error of 1.00D. No retinal or choroidal detachment was seen. Conclusion Phacoemulsification and implantation of negative-power posterior chamber intraocular lenses （IOL） is safe and effective in patients with super high myopia and cataract. It can correct the refractive errors, meanwhile improve the stability of the tissue in eyeball and reduce the occurrence of retinal detachment.
