AIM:To compare the surgical outcomes of a multifocal intraocular lens(IOL;Lentis Comfort LS-313 MF15)with those of an enhanced monofocal IOL(Tecnis Eyhance DIB00V).METHODS:This retrospective study included patients who underwent cataract surgery with LS-313 MF15 or Eyhance IOL implantation.Data regarding patient demographics,surgical records,and ophthalmic examination before the cataract surgery and one and three months postoperatively were collected.Visual acuities,refractive values,defocus curves,contrast sensitivities and subjective symptoms were evaluated.RESULTS:Among the 71 eyes(47 patients)included in this study,32 eyes(20 patients)underwent LS-313 MF15 IOL implantation,and 39 eyes(27 patients)underwent Eyhance IOL implantation.No significant differences were observed in age,axial length,or refractive error between the two groups preoperatively.Furthermore,the distancecorrected and uncorrected distance visual acuities one month postoperatively did not differ between the groups,and both groups had sufficient visual acuities at the distances of 5,1 m,70,50,and 30 cm.Other ophthalmic data,including subjective symptoms based on the 14-item Visual Function Index Questionnaire,monocular defocus curves,contrast sensitivities,and halo and glare,did not differ between the groups three months postoperatively.Moreover,both groups had good outcomes.The spherical equivalent one month postoperatively was significantly myopic in the LS-313 MF15 group compared with that in the Eyhance group(P=0.033);however,this difference was not observed three months postoperatively(P=0.471).CONCLUSION:Comparison of the surgical outcomes of LS-313 MF15 with those of Eyhance with different optical properties reveal that both IOLs show good postoperative outcomes,with no significant differences being noted between the two IOLs.
目的:鉴定Dib阴性孕妇不规则抗体特异性并筛选配合血液,探讨稀有血型孕妇围产期供血保障策略。方法:对医院不规则抗体筛查阳性的孕妇进行免疫血清学抗体鉴定,对照筛选细胞及谱细胞格局,鉴定为抗Dib稀有血型抗体后,在亲属血源及稀有血型库寻找配血相合的血液或尽早考虑自体输血。结果:2例围产期孕妇不规则抗体鉴定为抗Dib抗体,亲属血源中均存在鉴定为同血型Dib阴性的血液,且与孕妇主侧配血相合;另有稀有血型库存2 U Dib阴性冻存血液;筛选的血液和冻存血液后续被用于孕妇输血及其新生儿溶血病的治疗。结论:重视围产期孕妇不规则抗体检测及供血保障,持续更新并加强稀有血型库建设,可以有效改善孕妇及新生儿紧急输血需求,预防或治疗母胎血型同种免疫诱发的胎儿/新生儿溶血病。
