Cachet人工晶状体植入术矫正高度近视疗效的初步观察

The clinical observation of Cachet phakic anterior chamber IOL implantation in the correction of high myopia

目的:探讨有晶体眼前房角支撑型Cachet人工晶状体植入术矫正高度近视的有效性及安全性。方法:分析研究我院2011-05/12的12例22眼进行有晶体眼前房角支撑型人工晶状体植入术的高度近视患者。观察术前及术后视力、眼压、角膜内皮细胞密度计数和并发症等。术后随访3～6mo。结果:术眼均成功植入人工晶状体,术中未出现并发症,术后术眼裸眼视力明显改善,达到或超过术前最佳矫正视力,随访期间术眼眼压正常,术后6mo角膜内皮计数丢失率低,为2.11%～3.92%(3.17%±0.49%)。人工晶状体位置良好,与中央角膜内皮及晶状体距离安全。并发症少,恢复快。结论:新型Cachet前房角支撑型有晶状体眼人工晶状体植入术治疗高度近视,视力恢复快,预测性好,无明显并发症,是治疗高度近视的一种有效方法,但安全性需进一步随访观察。

AIM ： To observe the safety and clinical effects of Cachet IOL implantation in the correction of high myopia. METHODS： Twelve high myopia patients with Cachet anterior chamber IOL implantation from May 2011 to December 2011 were recruited in clinical study. The change of vision, lOP, corneal endothelium and the complication were observed after therapy. The follow up time was 3-6 months. RESULTS： In all eyes of 12 patients, the uncorrected distance visual acuity （UDVA） and corrected distance visual acuity （CDVA） were obviously improved in different degrees after surgery compared with those of pre-therapy. The anterior chamber was clear at 2 days after therapy. The loss rate of corneal endothelium was low, the IOL of all patients had a good position and there were no obvious complication after therapy. CONCLUSION： The Cachet IOL implantation is an accurate method in the correction of high myopia. It is an effective therapy to lighten the response of anterior chamber, and remission of complication and improve the vision. However, its safety needs long time observation.
