玻璃体切除联合晶状体摘除术后不同时期行人工晶状体植入术对高度近视孔源性视网膜脱离患者血流参数及视觉质量的影响

Effects of intraocular lens implantation at different stages after vitrectomy combined with lens extraction on blood flow parameters and visual quality in patients with high myopia and rhegmatogenous retinal detachment

目的探讨玻璃体切除联合晶状体摘除术后不同时期行人工晶状体植入术治疗高度近视孔源性视网膜脱离患者的效果。方法选取2020年6月至2022年6月我院收治的100例高度近视孔源性视网膜脱离患者为研究对象,以随机数字表法将其分为A组(50例,玻璃体切除联合晶状体摘除术后Ⅰ期行人工晶状体植入术)和B组(50例,玻璃体切除联合晶状体摘除术后Ⅱ期行人工晶状体植入术)。比较两组的治疗效果。结果取油前1个月、取油后1个月,A组的舒张末期血流速度(EDFV)、平均血流速度(Vm)高于B组(P<0.05)。取油前1个月、取油后1个月,A组的视力高于B组,臂-视网膜循环时间(A-RCT)短于B组(P<0.05)。取油前1个月、取油后1个月,A组的看电视、阅读书写、夜间视物及精细操作评分高于B组(P<0.05)。结论玻璃体切除联合晶状体摘除术后Ⅰ期行人工晶状体植入术治疗高度近视孔源性视网膜脱离患者有助于促进血流参数改善,加快视力恢复,提高早期视觉质量。

Objective To investigate the effects of intraocular lens implantation at different stages after vitrectomy combined with lens extraction on patients with high myopia and rhegmatogenous retinal detachment.Methods A total of 100 patients with high myopia and rhegmatogenous retinal detachment admitted in our hospital from June 2020 to June 2022 were selected as the research objects.The patients were divided into group A(50 cases,Ⅰstage intraocular lens implantation was performed after vitrectomy combined with lens extraction)and group B(50 cases,Ⅱstage intraocular lens implantation was performed after vitrectomy combined with lens extraction)by random number table method.The therapeutic effects of the two groups were compared.Results One month before and one month after oil removal,the end diastolic flow velocity(EDFV)and mean blood flow velocity(Vm)in the group A were higher than those in the group B(P<0.05).One month before and one month after oil removal,the visual acuity of the group A was higher than that of the group B,and the arm to retina circulation time(A-RCT)was shorter than that of the group B(P<0.05).One month before and one month after oil removal,the scores of watching TV,reading and writing,night vision and fine operation in the group A were higher than those in the group B(P<0.05).ConclusionⅠstage intraocular lens implantation after vitrectomy combined with lens extraction is helpful to promote the improvement of blood flow parameters,accelerate the recovery of visual acuity and improve the early visual quality in patients with high myopia and rhegmatogenous retinal detachment.
