目的:评价高度近视眼合并白内障行超声乳化白内障摘除并低、负度数人工晶体植入的疗效。方法63例68眼高度近视眼合并白内障行反眉状隧遂道式自闭性切口行超声乳化摘除术,5.5mm切口植入人工晶体,眼轴26mm-30mm者38眼,>30mm者30只眼。随访0.5年-2年,观察超声能量、时间、术后不同眼轴视力和并发症。结果:眼轴26mm-30mm组术后3月视力≥0.5者34只眼,占89.5％;>30mm组术后3月视力≥0.5者15只眼,占50.0％。后囊膜破损并玻璃体溢出3只眼(4.4％)半年后发生视网膜脱离2只眼(2.9％),角膜水肿11只眼(16.1％)。术后3个月视力比较有显著性差异(p<0.05)。结论:高度近视眼合并白内障行超声乳化白内障摘除并低、负度数人工晶体植入术可提高患者视力,改善视功能,但>30mm组效果较差。
Objective: To evaluate the efficacy of phacoemulsification cataract extraction combined with low and negative intraocular lens implantation in highly myopic eyes with cataract. Methods Sixty-three eyes of 68 eyes with high myopia and cataract were treated with phacoemulsification and intraocular lens implantation with a 5.5 mm incision. Thirty-eight eyes (26mm-30mm) and 30 eyes> 30mm eye. Follow-up 0.5 to 2 years, observe the ultrasonic energy, time, postoperative different ocular axial visual acuity and complications. Results: There were 34 eyes (89.5%) with visual acuity ≥0.5 at 3 months after operation in 26mm-30mm group, and 15 eyes (≥50%) at 15 months after operation in 30mm group. Posterior capsular rupture and vitreous spill occurred in 3 eyes (4.4%). Two eyes (2.9%) had retinal detachment and 11 eyes (16.1%) had corneal edema six months later. After 3 months visual acuity was significantly different (p <0.05). Conclusion: Phacoemulsification cataract extraction combined with low and negative intraocular lens implantation in high myopia with cataract can improve visual acuity and visual function in patients with> 30 mm.
