【摘要】 目的评估V4c与普通人工晶体(ICL)晶体植入术矫治近视的疗效及安全性。方法对高度近视患者12例24眼接受V4c型晶体治疗,26例48眼接受普通型ICL治疗,术前屈光度球镜-6.0~-20.0D,手术后随访1个月,观察:裸眼视力,最佳矫正视力(BCVA)、膜地形图、主观和客观验光、角膜内皮细胞计数、眼压测量、裂隙灯检查指标以及术后视觉质量调查问卷。结果术后1月,V4c型晶体和普通型晶体患者的裸眼视力都较术前明显提高,差异有统计学意义(P<0.05),且术后V4c型晶体较普通型晶体裸眼视力更好,差异有统计学意义(t=3.272,P=0.003)。术后V4c型晶体和普通型晶体患者的眼压较术前无明显变化,差异无统计学意义(P>0.05)。结论 V4c型晶体植入术矫正近视比普通型ICL具有更好的疗效和安全性,远期效果有待进一步观察。更多还原

【Abstract】 Objective To evaluate the efficacy and safety of V4 cand ordinary intraocular lens(ICL)implantation for correcting myopia.Methods Twelve cases(24eyes)of high myopia accepted the V4 ctype crystal treatment and 26cases(48eyes)received the ordinary ICL therapy.The preoperative spherical equivalent refraction was-6.0--20.0D.The uncorrected visual acuity(UCVA),best corrected visual acuity(BCVA),membrane topography,subjective and objective optometry,corneal endothelial cell counts,intraocular pressure measurement,slit lamp examination index and postoperative visual quality questionnaire were observed during postoperative 1-month follow up.Results The UCVA at postoperative 1month in the patients with V4 ctype crystals and ordinary crystal was obviously increased compared with that before operation,the difference was statistically significant(P<0.05),moreover V4 ctype crystal had better UCVA than ordinary ICL,the difference was statistically significant(t=3.272,P=3.272).Postoperative intraocular pressure in V4 ctype crystal and ordinary ICL had no obvious change compared with before operation,the difference had no statistically significant difference(P>0.05).Conclusion The V4 ctype lens implantation for correcting myopia has better effect and safety than ordinary ICL but its long-term effect remains to be further observed.更多还原
