有晶状体眼后房型人工晶状体植入矫正高度近视的临床观察

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

目的探讨有晶状体眼后房型人工晶状体植入术矫正高度近视的有效性和安全性。方法后房型人工晶状体植入治疗高度近视眼患者8例15眼,术后随访分别检查裸眼视力、矫正视力、眼压、角膜及前房情况,UBM观察人工晶体位置。结果 15眼均顺利完成手术,术后视力均达到或超过术前最好矫正视力。术后眼压及人工晶体位置正常,术后1周内有2眼出现人工晶体表面少量色索。随访1年,视力稳定,未出现晶体混浊及眼压升高等严重并发症。结论有晶体眼后房型人工晶体植入治疗高度近视,视力恢复迅速,未发生严重并发症,预测性好,具有安全性和有效性。

Objective To examine the efficacy and safety of the phakic posterior chamber intraocular lens （IOL） implantation correcting high myopia. Methods Eight patients （ fifteen eyes） with high myopia who were performed with surgery treatment. The author examined uncor- rected visual acuity, best corrected visual acuity, intraocular pressure（ IOP）, cornea and anterior chamber, position of IOL, and ultrasound bio- logical microscope （UBM） were examined in postoperative follow -up. Results Fifteen eyes were performed with surgery successfully;postoper- ative visual acuity in each case reaches and even exceeds the best corrected vision before operation;postoperative lOP was normal;intraoeular lens position was normal; in the one - year follow - up, no serious complications, such as lens opacity, higher lOP and so on, occurred. Conclu- sion The phakic IOL corrects high myopia, makes patients recover their visual acuity quickly, and has no serious complications. It has good pre-dictability, safety and effectiveness.
