简介:摘要目的:应用Pentacam测量角膜中央3 mm前表面曲率(Ra)、后表面曲率(Rp)及中央角膜厚度(CCT),根据测量结果,探讨角膜屈光力及角膜屈光指数的计算方法。方法:系列病例研究。选取2017年2─10月在湘潭市中心医院和温州医科大学附属眼视光医院接受角膜屈光手术或白内障手术术前检查的患者419例(419眼)。术前采用Pentacam对眼前节进行检查,采集角膜中央3 mm Ra、RP及CCT的相关数据,计算Ra与Rp比值(AP ratio)、角膜前表面屈光力(Ka)以及后表面屈光力(Kp),按照厚透镜高斯光学公式计算角膜总屈光力(KGOF)及角膜屈光指数(Ncal)。采用配对样本t检验比较各种K值之间的差异。结果:Pentacam测量所得Ra、Rp、Rsimk、CCT、SimK分别为(7.73±0.27)mm、(6.34±0.24)mm、(7.73±0.27)mm、(537±33)μm、(43.65±1.52)D。AP ratio为1.220±0.026,角膜屈光指数Ncal为1.328±0.001。结论:利用Pentacam测量角膜参数计算所得角膜屈光指数可以提高角膜总屈光力及角膜后表面屈光力预算的准确性。
简介:摘要目的评价窄谱强脉冲光冰点模式脱毛的疗效及安全性.方法对132例患者采用窄谱强脉冲光进行脱毛治疗,观察不同部位包括唇部、腋部、四肢及躯干部等治疗次数及疗效,并对效果及安全性进行评价.结果132例患者经连续治疗后均达到理想的脱毛效果,治疗后毛发明显减少,再生毛发细小、稀疏.腋部的总有效率为100%,双上肢为92%,双下肢为95??3%,躯干部为85??6%,唇部为70??4%.随着治疗次数的增加,疗效逐步提高.所有患者无明显疼痛感,均未出现色素沉着或减退、瘢痕等不良反应.结论窄谱强脉冲光冰点模式脱毛无明显疼痛,安全、快速、有效.关键词窄谱强脉冲光;脱毛;疗效EvaluationofCurativeEffectonHairRemovalwithFreezingmodebyNarrow-spectrumintensepulsedlightQiuShi,WanLimin,ShengYanli,ShiRuiping,WangHong,QiYanhong(DepartmentofDermatovenereology,ShunyiDistrictHospitalofBeijing,Beijing101300,China)CorrespondingauthorQiuShi,E-mailqsh0322@163??comAbstractObjectiveToevaluatetheefficacyandsafetyofhairremovalwithFreezingmodebyNarrow-spectrumintensepulsedlight(DPL)??MethodsForhairremovaltreatmentof132patientswithNarrow-spectrumintensepulsedlight(DPL650-950nm),curativeeffectandtreatmenttimeswereobservedondifGferentpartsincludingthelip,axillaries,limbsandtrunk??aswelltheadversereactionandregenerationofhairwereobservedin132patients??Thetreatmenteffectandsafetywasevaluatedatthesametime??ResultsAftercontinuoustreatmentwithNarrow-spectrumintensepulsedlight,132patientsallobtainedsatisfactoryeffects??Theclinicalmanifestationswereobviouslylesshair,theregenerationofsmallandsparsehair??Thetotalefficiencyonaxillaries,upperlimbs,Thelegs,trunk,lip,were100%,92%,95??3%,85??6%and70??4%respectively??ThetotaleffectiveratewasgraduallyheightenedwiththeincreaseinthenumberoftreatGment??Allpatientshadnosignificantpain,hypopigmentation,hyperpigmentation,andscar??ConclusionsNarrow-spectrumintensepulsedlightcanbeconsideredasanoKeoybvwioorudsspain,safe,fast,efficienttreatmentonhairremovalwithFreezingmode??Narrow-spectrumintensepulsedlight;HairRemoval;Curativeeffect中图分类号R730.5文献标识码B文章编号1008-6315(2015)12-1086-01
