目的临床观察应用超声乳化技术摘除尚透明的晶状体后植入后房型人工晶体矫正中老年高度近视眼的有效性和安全性。方法对49例96眼,45岁以上晶状体尚透明的高度近视眼患者行超声乳化透明晶状体摘除联合后房折叠型人工晶体植入术,观察手术前后的视力、屈光状态、角膜曲率、眼压、内皮细胞计数、立体视觉、脱镜率、病人视力习惯和满意程度。结果术后所有患者裸眼视力均提高,≥0.5者88眼(91.67%);最佳矫正视力均达到或好于术前;术后屈光度数预测准确性为70.2%;多焦点晶体植入患者术后脱镜率为85.7%;术中无手术相关的并发症发生;随访期内未出现后囊膜混浊,未发现黄斑囊样水肿及视网膜脱离等并发症。结论以成熟的超声乳化技术行透明晶状体摘除联合后房型人工晶体植入矫正中老年高度近视眼的方法安全、有效,多焦点人工晶体植入有助于提高患者术后脱镜率,手术远期效果有待进一步研究。
Objective To observe the effectiveness and safety of phacoemulsification in the treatment of middle-aged and high-myopic eyes after phacoemulsification with a transparent lens and posterior chamber intraocular lens implantation. Methods Forty-nine patients (96 eyes) with clear myopia who were above 45 years of age were treated with phacoemulsification and posterior chamber foldable intraocular lens implantation. Visual acuity, refractive status, corneal curvature, intraocular pressure , Endothelial cell count, stereopsis, debridement rate, patient visual acuity and satisfaction. Results The postoperative uncorrected visual acuity of all patients was improved, 88 eyes (91.67%) ≥0.5, the best corrected visual acuity was achieved or better than preoperative, and the predictive accuracy of postoperative refractive power was 70.2%. The multifocal lens implantation The posterior mirror rate was 85.7%. No operative complications occurred during the operation. No posterior capsular opacity occurred during the follow-up period. No complications such as macular cystoid edema and retinal detachment were found. Conclusion The method of phacoemulsification combined with posterior chamber intraocular lens implantation in the treatment of high myopia in middle-aged and elderly patients is safe and effective. The implantation of multifocal intraocular lens (IOL) is helpful to improve the rate of postoperative conjunctival surgery, The effect needs further study.
