有晶状体眼后房散光型IOL植入矫正高度近视散光

目的：评价有晶状体眼后房散光型人工晶状体(TICL)植入术矫治高度近视散光的临床效果。

方法：选自2009-10/2011-11接受TICL植入的高度近视散光患者30例50眼，术前平均屈光度球镜-10.75±2.65D，柱镜-2.85±0.75D。随访观察术后3mo～2a裸眼视力、最佳矫正视力、屈光度、内皮细胞计数等情况，分析并发症的发生情况。

结果：术后裸眼视力：0.5～1.2(平均0.75±0.34)。术前最佳矫正视力：0.3～1.0(平均0.58±0.35)，术后最佳矫正视力0.6～1.2(平均0.78±0.35)。达到术前矫正视力20眼(40%)，超过术前最佳矫正视力30眼(60%)，随访3mo～2a，视力无明显变化。术后屈光度数平均球镜-0.52±0.35D，柱镜0.52±0.25D。角膜内皮细胞计数术前3 026±250个/mm²，术后3mo为3 023±246个/mm²，差异无统计学意义(P<0.05)。未见严重影响视力的并发症。

结论：TICL植入矫治高度近视散光安全有效，是高度近视散光患者的理想治疗方法。对眼内的长期影响需要进一步观察。

Clinical study of the implantation of phakic posterior chamber Toric intraocular lens for high myopia with astigmatism

AIM: To assess the clinical outcome of the implantation of phakic posterior chamber Toric intraocular lens(TICL)for high myopia with astigmatism.

METHODS: Totally 50 eyes of 30 patients with high myopia and astigmatism were treated with TICL implantation from October 2009 to November 2011. The preoperative mean spherical equivalent was -10.75±2.65D, the mean cylindrical equivalent was -2.85±0.75D. All of the patients were followed up for 3 months to 2 years. Uncorrected and best-corrected visual acuity, refraction, intraocular pressure and endothelial cell morphometry, as well as the complications were observed.

RESULTS: The range of uncorrected visual acuity after operation was 0.5-1.2, mean 0.75±0.34. The range of preoperative best-corrected visual acuity was 0.3-1.0, mean 0.58±0.35. The mean best-corrected visual acuity after operation was 0.78±0.35. The uncorrected visual acuity after operation of 20 eyes was same and of 30 eyes was better than the preoperative best-corrected visual acuity. The mean spherical equivalent after operation was -0.52±0.35D, the mean cylindrical equivalent was 0.52±0.25D. Corneal endothelium counting before and after the operation had no significant difference. No serious complication was detected during the follow-up.

CONCLUSION: The implantation of phakic posterior chamber TICL for high myopia with astigmatism is safe and effective. It is a suitable treatment method for high myopia.
