有晶状体眼后房型人工晶状体植入术矫正高度近视

探讨有晶状体眼后房型人工晶状体（phakic intraocular lens，PIOL）植入术矫正高度近视的有效性和安全性。 方法：本研究中高度近视患者17例33眼，术前屈光度-8.00～-24.00 (平均-15.46±6.26)D,眼轴长度25.33～33.77(平均30.22±2.55)mm。33眼植入后房型人工晶状体也称植入性接触镜（implantable contact lens,ICL& toric implantable collamer lens, TICL）。其中，22眼植入ICL，11眼植入TICL。术后观察视力、屈光度、眼压、人工晶状体位置等。 结果：所有病例均成功植入后房型人工晶状体。术后1wk，所有手术眼达到或超过术前最佳矫正视力，屈光度和眼压稳定。 结论：有晶状体眼后房型人工晶状体植入术治疗高度近视安全有效，适用屈光度范围广，术后屈光度稳定，视觉质量提高

Clinical research on the implantation of posterior chamber phakic intraocular lens for correction of high myopia

AIM:To observe and investigate the efficacy and safety of the implantation of posterior chamber phakic intraocular lens for high myopia.METHODS:In the research,17 cases(33 eyes) with high myopia were treated with posterior chamber phakic intraocular lens implantation,among them 22 eyes were implanted with implantable contact lens(ICL) and 11 eyes with toric implantable contact lens(TICL).The preoperative refraction was-8.00-24.00 dioper(mean-15.46 ±6.26D)and eyeball length was 25.33-33.77mm(mean 30.22±2.55mm).The visual acuity,refraction,intraocular pressure and position of the intraocular lens were examined after operation.RESULTS:All of 33 eyes were implanted successfully.The uncorrected visual acuity of every eye was the same or even better than preoperative best-corrective visual acuity,the intraocular pressures were normal and the refraction remained stable after postoperative follow-up of 6 months.CONCLUSION:The implantation of posterior chamber phakic intraocular lens was efficacious and safe.It provides much more potential choices for patients with refractive errors.The patients can gain better visual acuity and maintain it after operation.
