Abstract

PURPOSE

To evaluate visual benefit, predictability and complications after clear lens phakoemulsification and posterior chamber implantation in highly myopic eyes.

METHODS

Thirty-three highly myopic eyes were reviewed at a mean postoperative follow-up of 27 months. The mean age of the 19 patients was 31.04 +/- 5.51 years. The mean preoperative spherical equivalent was -19.50 +/- 7.0 D (-12 to -40 D). Preoperative best spectacle corrected visual acuity was compared with the last postoperative one. Postoperative spherical equivalent was compared with the desired value. All complications were reviewed.

RESULTS

A mean visual benefit of 0.24 +/- 0.18 (decimal notation) was noted (p < 0.05). The mean postoperative spherical equivalent (-2.57 +/- 1.84 D) was not significantly different from the mean previous value (p = 0.75). Retinal detachment arose in the two eyes of the same patient (incidence of 6.1%). BSCVA decreased slightly in only one of the two eyes (0.1). The incidence of Nd-YAG capsulotomy was 30%.

CONCLUSION

Clear lens phakoemulsification is an effective and predictable method for the correction of high myopia. Retinal detachment is the major complication of this technique, even if a severe decrease of the visual acuity is not usual.

摘要

目的

评估高度近视眼透明晶状体超声乳化及后房型人工晶状体植入术后的视觉效果、可预测性及并发症。

方法

对33只高度近视眼进行回顾性研究，术后平均随访27个月。19例患者的平均年龄为31.04±5.51岁。术前平均等效球镜度为-19.50±7.0D（-12至-40D）。将术前最佳矫正视力与术后最后一次视力进行比较。将术后等效球镜度与预期值进行比较。对所有并发症进行回顾。

结果

平均视觉提高为0.24±0.18（小数表示法）（p<0.05）。术后平均等效球镜度（-2.57±1.84D）与术前平均值无显著差异（p=0.75）。同一患者的两只眼发生视网膜脱离（发生率为6.1%）。仅两只眼中的一只眼最佳矫正视力（BSCVA）略有下降（0.1）。钕-YAG激光后囊切开术的发生率为30%。
