To evaluate the efficacy and safety of the clear lens removal to compensate the myopic refractive error.
Retrospective analysis of 40 myopic eyes with axial length more than 27 mm, treated by phacoemulsification and posterior chamber lens implantation. Mean follow-up 45.9 months (17 to 118). Analysed parameters: postoperative uncorrected and bestcorrected visual acuity, comparison of pre- and postoperative bestcorrected visual acuity, intra- and postoperative complications, predictability of refraction, subjective satisfaction score.
Axial length 30.63 +/- 2.0 mm (min. 27, max. 36.8 mm). Preoperative myopia -14.50 +/- 3.6 dpt. Bestcorrected preoperative visual acuity 0.40 +/- 0.19 (min. 0.1, max. 0.8). Bestcorrected postoperative visual acuity 0.71 +/- 0.25 (min. 0.16, max. 1.25). No loss of best corrected visual acuity. Posterior capsule opacification requiring YAG-capsulotomy occurred in 50%. One eye developed cystoid macular edema, no retinal detachment were observed postoperatively. All patients were satisfied or very satisfied.
Clear Lens Extraction for severe myopia is safe, for the patient satisfying and is a valid alternative to corneal refractive surgery.
评估摘除透明晶状体以矫正近视屈光不正的疗效和安全性。
回顾性分析40例眼轴长度超过27mm的近视眼,采用超声乳化白内障吸除术及后房型人工晶状体植入术治疗。平均随访45.9个月(17至118个月)。分析参数包括:术后未矫正及最佳矫正视力、术前和术后最佳矫正视力比较、术中及术后并发症、屈光预测性、主观满意度评分。
眼轴长度30.63±2.0mm(最小值27,最大值36.8mm)。术前近视-14.50±3.6屈光度。术前最佳矫正视力0.40±0.19(最小值0.1,最大值0.8)。术后最佳矫正视力0.71±0.25(最小值0.16,最大值1.25)。最佳矫正视力无下降。50%的患者发生后囊膜混浊需要行YAG激光后囊切开术。1只眼发生黄斑囊样水肿,术后未观察到视网膜脱离。所有患者均满意或非常满意。
对于高度近视患者,透明晶状体摘除术是安全的,患者满意度高,是角膜屈光手术的有效替代方法。
