目的 :探讨采用超声乳化联合人工晶状体植入术治疗高度近视的疗效。方法 :对 31例 (41只眼 )高度近视眼经透明角膜切口或巩膜隧道切口行超声乳化联合人工晶状体植入术 ,平均年龄 (44 2 1± 5 33)岁 ,术前最佳矫正视力为指数 / 30cm～ 0 6 ,平均等效球镜度数为 (- 15 5 4± 4 13)D ,平均眼轴长度为 (2 8 4 5± 5 13)mm ,植入人工晶状体屈光度 (- 7 0～+14 5 )D。结果 :所有病例术后矫正视力均超过术前最佳矫正视力 ,术后裸眼视力达到或超过术前最佳矫正视力者 31只眼(75 6 % ) ,术后裸眼视力达到或超过 0 5者 18只眼 (43 9% )。术后屈光度平均值为 (- 1 85± 1 32 )D ,37只眼 (90 2 % )在设计预矫屈光度± 1D内 ,39只眼 (95 1% )在预矫屈光度± 2D内。术后 6～ 2 4个月 (平均 15个月 )随访期中 ,5只眼 (12 2 % )发生后囊膜混浊。未发现视网膜脱离、黄斑囊样水肿、眼底出血、青光眼、人工晶状体偏位等并发症。结论 :超声乳化透明晶状体摘除联合人工晶状体植入术是治疗高度近视安全、有效的方法 ,具有术后视力好、并发症少、预测屈光状态准确性及稳定性较好等优点。其远期疗效有待观察。
Objective: To investigate the effect of phacoemulsification combined with intraocular lens implantation in the treatment of high myopia. Methods: Thirty-one eyes (41 eyes) with high myopia underwent phacoemulsification combined with intraocular lens implantation via clear corneal incision or scleral tunnel incision. The average age was 44 2 1 ± 5 33 years old. The best corrected visual acuity The mean equivalent axial spherical power was (-15 5 4 ± 4 13) D, the average axial length was (2 8 45 ± 5 13) mm, the intraocular lens refractive power (-70 ~ + 14 5) D. Results: The corrected visual acuity of all cases surpassed preoperative best corrected visual acuity. The postoperative uncorrected visual acuity reached or exceeded 31 preoperative best corrected visual acuity (75 6%), postoperative uncorrected visual acuity reached or exceeded 0.5 18 eyes (43 9%). The mean postoperative refraction was (-1 85 ± 1 32) D, and 37 eyes (90 2%) were within ± 1D of the design pre-dilatation luminosity and 39 eyes (95 1%) were within ± 2 D of the pre-dilation diopter. Postoperative 6 to 24 months (mean 15 months) follow-up period, 5 eyes (12 2%) posterior capsular opacification. No retinal detachment, cystoid macular edema, retinal hemorrhage, glaucoma, intraocular lens deviation and other complications were found. CONCLUSION: Phacoemulsification and phacoemulsification combined with intraocular lens implantation are safe and effective methods for the treatment of high myopia. They have the advantages of good postoperative visual acuity, fewer complications, better prediction of refractive status and better stability. Its long-term efficacy remains to be seen.
