Background:To evaluate the long-term safety,efficacy,predictability,and stability of implantable collamer lens with a central hole(EVO ICL)implantation for correcting high myopia(HM)and super high myopia(SHM).Methods:...Background:To evaluate the long-term safety,efficacy,predictability,and stability of implantable collamer lens with a central hole(EVO ICL)implantation for correcting high myopia(HM)and super high myopia(SHM).Methods:This prospective study evaluated 83 eyes of 46 patients who were divided into groups based on their spherical equivalent refractive error(SE):HM group(−12 D≤SE<−6 D)and SHM group(SE<−12 D).They were followed up for 5 years after ICL implantation;assessments of uncorrected distance visual acuity(UDVA),corrected distance visual acuity(CDVA),manifest refractive error,axial length,intraocular pressure,corneal endothelial cell density,and vault were conducted,and a questionnaire was administered.ResuIts:At 5 years postoperatively,the safety indices of the HM and SHM groups were 1.03±0.10 and 1.32±0.39,and the efficacy indices were 0.83±0.25 and 0.86±0.32,respectively.In the HM group,60.47%and 79.07%of the eyes were within±0.50 D and±1.00 D of the attempted correction,while it was achieved for 22.50%and 47.50%of the eyes in the SHM group,respectively.The SE of the HM group decreased from−9.72±1.41 D preoperatively to 0.04±0.39 D 1 month postoperatively and−0.67±0.57 D 5 years postoperatively,while in the SHM group,it decreased from−15.78±3.06 D preoperatively to−0.69±0.97 D 1 month postoperatively and−1.74±1.19 D 5 years postoperatively.Conclusion:EVO ICL implantation is safe,effective,and predictable for correcting HM and SHM.CDVA improved more after surgery for SHM,but the growth of axial length still needs attention.展开更多

文摘目的:回顾分析超高度近视合并孔源性视网膜脱离(rhegmatogenous retinal detachment,RRD)的手术方式、手术效果、术后并发症及处理方法。方法:选择2011-01-01/2016-01-01于我院就诊的超高度近视合并RRD的患者47例47眼,并于我院行巩膜外加压术,玻璃体切除(pars plana vitrectomy,PPV)联合硅油填充术,或玻璃体腔注气术,回顾分析术后6mo内患者的BCVA、眼压、视网膜复位情况、裂孔闭合程度及术后并发症。结果:患者术后6mo时行PPV联合硅油填充的患者视力提高者24眼(71%);单纯行巩膜外加压术的患者视力提高8眼(73%)。统计学检验可见手术治疗能明显改善患者视力,尤其PPV联合硅油填充,但单纯行巩膜外加压术患者视力在本研究中经统计学检验显示无明显意义。PPV联合硅油填充的患者术后高眼压及复视等术后并发症较其他术式更多。结论:超高度近视合并孔源性视网膜脱离的患者需要及时行手术治疗,对术者临床经验及手术要求极高,需要术者根据视网膜裂孔的大小、位置及视网膜脱离范围选择不同的术式,及时恰当处理术后并发症,以争取患者术后裂孔最大程度的闭合、提高视网膜复位率及视功能,提高患者生活质量。
