有晶状体眼前房人工晶体植入矫正超高度近视初步报告

Preliminary Report Of Implanting Phakic-6H-125 Intraocular Lens For Super High Myopia

目的 :观察有晶体眼前房人工晶体植入矫正超高度近视的临床效果。方法 :11例 ( 18眼 )度数在 -11 0 0D～ -30 0 0D (平均 2 1 2 5D)之间的超高度近视患者表麻下前房内植入Phakic6H12 5型人工晶体 ,随访 6～ 12个月 (平均 9 7月 )。结果 :18眼术后裸眼视力均≥术前矫正视力 ( 0 6 4>0 39) ,两者比较差别有显著性意义 (P <0 0 5 )。术后散光明显减轻 ,与术前相比较差别有显著性意义 (P <0 0 5 )。手术前后眼压比较差别无显著性意义 (P >0 0 5 )。三眼轻微瞳孔变形 ,一例 (双眼 )出现眩光感。结论 :初步观察有晶体眼前房人工晶体植入矫正超高度近视具有安全性、稳定性、可预测性 ,是一种颇具前途的矫正超高度近视的手术。不适宜作LASIK的超高度近视患者可谨慎选择该手术。

Objective:To observe the clinical effect of implanting Phakic-6H-125 anterior chamber intraocular lens(PACLs)in anterior chamber to correct super-high myopia. Methods:11 cases(18 eyes)of super-high myopia with -11.00D～-30.00D(averaging -21.25D)accepted PACLs implantation in anterior chamber with surface anesthesia,and were followed up for 6～12 months(averaging 9.7 months). Results:After the operation,uncorrected vision of 18 eyes(mean 0.64)was better than or equal to preoperative corrective vision(mean 0.39)(P<0.05).Astigmatism relieved obviously after the operation(P<0.05).The difference in intraocular pressure was not significant(P>0.05).Slight pupil deformation occurred in 3 eyes and dazzling sensation occurred in 2 eyes(one case). Conclusion:Implanting PACLs to correct super-high myopia is safe,stable and predictable,it seems much valuable for those patients who are not fit for LASIK.
