Xa izigulane zizisa isihloko seelensi zokudibanisa ezinemibala, into yokuqala efika engqondweni kukutshintsha umbala wamehlo.Ngaphezu kwezizathu zokuthambisa, iilensi zokudibanisa ezinemibala okanye ezinemibala zinokunceda izigulane ngeendlela ezininzi, ezifana nokunciphisa ukukhanya okanye ukutshintsha umbala. ukuqonda kubantu abanobumfama bombala.
Kungakhathaliseki ukuba i-cosmetic okanye ukusetyenziswa kwezonyango, iilensi zokudibanisa ezinemibala ngokuqhelekileyo azikho i-OD ebhekisela kwizigulane.Nangona kunjalo, xa kucetyiswa, banomdla kwizigulane ezininzi.
umbala weelensi zoqhagamshelwano
Iingcebiso zingenziwa kwii-angles ezahlukeneyo.Kungakhathaliseki ukuba zihanjiswa njani, kubalulekile ukuqaphela ukuba ngelixa iilensi ezifakwe kwi-tinted zinokuthi zincede izigulane, zithwala ingozi abaninzi abangaziyo.
Iilensi zokudibanisa ezinemibala eveliswe ngobuninzi Iilensi zokudibanisa ezinemibala enemibala zinokufumaneka kwiikiti ze-try-on kits kwaye zihanjiswa ngokulula kwi-ofisi yokumisela.Ngokuphindaphindiweyo, ezi zithonga zenziwe ngekhompyutha.Ngoko ke, i-OD ayikwazi ukuguqula iiparitha ezifana nokugcwala, ukukhanya, okanye ulungelelwaniso lombala.
Iilensi zokudibanisa ezinombala eziveliswe ngobuninzi zinokuphucula umbala wendalo weliso lesigulane okanye zitshintshe ngokupheleleyo.Zifana neelensi ezininzi ezithambileyo ezisetyenziselwa ukulungisa iimpazamo ze-refractive.Ngoko ke, akukho xesha lokuhlala elongezelelweyo elifunekayo xa kuthelekiswa noqhagamshelwano oluthambileyo oluveliswe ngobuninzi. iilensi.
Uninzi lweelensi ezinemibala eveliswa ngobuninzi zinamandla angqukuva atshintshwa imihla ngemihla okanye ngenyanga. Iilensi azibizi kakhulu ngenxa yemveliso yobuninzi, ngoko ke zinokuziswa ngokulula kwizigulana njengokhetho olusisigxina okanye lwethutyana.
Iilensi ezinemibala eveliswe ngobuninzi zihlala zithandwa kwimicimbi yentlalontle.1 Ngombulelo kwinkxaso yazo ecacileyo kunye ne-pigments enemibala ejikeleze iris, ivumela iipatheni ezahlukeneyo ezinokuthi zenze inkangeleko yendalo okanye enesibindi.
Ngokomzekelo, isigulane esinamehlo amdaka sinokukhetha umbala omdaka okanye i-hazel ukuba utshintshe kancinane umbala we-iris, okanye uhlaza okwesibhakabhaka okanye ohlaza ukuze utshintshe inkangeleko ngokumangalisayo.Nangona kulula ukufaka kunye nokufundisa izigulane malunga nokhetho lwabo, ezi lens zinezona ziphezulu. amazinga obunzima phakathi kwabanxibe iilensi zoqhagamshelwano.2
Iingxaki Nangona iingozi ze-cosmetic lens zicacile kwii-ODs ezibone iziphumo ze-ocular, uluntu ngokubanzi luhlala lungazi kakuhle isoyikiso abasibeka kwi-eye health.When Berenson et al.baphanda ulwazi lwezigulane kunye nokusetyenziswa kweelensi zokudibanisa izimonyo, iziphumo zibonise ukuba izigulane ezininzi aziqondi iingozi kunye nemiyalelo yokusetyenziswa ngokufanelekileyo.3,4 Ngokophando, isigulane esinye kwezine sabika ukuba sisebenzise iilensi zokuthambisa ngaphambili, kwaye abaninzi bafumana iilensi. kwimithombo engagunyaziswanga.
Xa ebuzwa malunga nolwazi lwe-lens yoqhagamshelwano, iziphumo zibonise ukuba izigulane ezininzi azizange zikwazi ukugqoka i-protocol efanelekileyo.3 Uninzi lwezigulane aziqondi ukuba akukho mthethweni ukuthengisa iilensi zoqhagamshelwano kwi-counter ngaphandle komyalelo welizwe lonke.Nabo abaqondi ukuba uqhagamshelwano iilensi azikho i-panacea, ukuba ii-parasites zinokuncamathela kwiilensi, kwaye iilensi "ze-anime" azivunywanga yi-FDA.3
EZIPHATHELELEYO: Iziphumo zovoto: Yintoni eyona nto ingakonelisiyo kakhulu nge-Contact Lens Wear?Kwizigulane eziphandwayo, i-62.3% yathi ayizange ifundiswe indlela yokucoca iilensi zoqhagamshelwano.3
Nangona sinokuqaphela ezinye zezi ziphumo, kubalulekile ukuhlola indlela iilensi ze-cosmetic zokwandisa ngayo ithuba leziganeko ezimbi (AEs) xa kuthelekiswa neelensi zoqhagamshelwano ezicacileyo.
I-AEs I-Color contact lens inomngcipheko ophezulu wokusuleleka kunye neziganeko ezivuthayo ngenxa yokubunjwa kwazo.Uphononongo olutshanje luhlolisise i-cosmetic contact lens ezahlukeneyo ukuze kuqinisekiswe indawo yee-pigments kwi-lens layers.5 Ifumene ukuba ininzi yeelensi ezihlalulweyo ziqulethe ezininzi I-pigment ngaphakathi kwe-0.4 mm yomphezulu.Amazwe amaninzi awawulawuli ubungakanani bepeyinti ezivaliweyo, kodwa indawo inokuchaphazela ukhuseleko kunye nentuthuzelo.5
Olunye uphononongo lufumanise ukuba uninzi lweempawu zelensi zonxibelelwano aluphumelelanga kuvavanyo lokukhuhla, nto leyo ebangela ukuba ibala elimibalabala lixobuke.6 Sula uvavanyo Sebenzisa umqhaphu weswab ukosula ngobunono umphezulu ongaphambili nangasemva welensi yoqhagamshelwano kangangemizuzwana engama-20, emva koko ulinganise isixa. yeqela lebala.

Ubukho bayo nayiphi na i-pigment kunokubangela i-AEs.Lau et al wafumanisa ukuba iilensi ezineebala kwi-lens surface (ngaphambili okanye ngasemva) zinexabiso eliphezulu kakhulu lokukhuhlana kwiindawo ezinemibala kuneendawo ezicacileyo.8 Izifundo ziye zagqiba ukuba iilensi zokuthambisa ezineebala eziveziweyo zineendawo ezingaguquguqukiyo kangako, ezibangela ukuthambisa kunye nokwanda koburhabaxa bomphezulu.Ukuthambisa kunye noburhabaxa zidlala indima ebalulekileyo ekugcineni uzinzo lwefilimu yeenyembezi.Ngenxa yoko, ukuphazamiseka kunokukhokelela kumbono ongazinzanga kunye nokunciphisa ukuthuthuzela kwelensi yoqhagamshelwano.
I-Acanthamoeba keratitis ingenzeka kunye nazo zonke iintlobo ze-lens zoqhagamshelwano, umngcipheko esixoxa ngawo nabo bonke abatsha. ukunciphisa ii-AEs ezinxulumene ne-microbes, kodwa uphando olutshanje lufumene ukuba ukubunjwa kwe-lens kuchaphazela amathuba okuba i-Acanthamoeba inamathele kwi-lens.9
Related: Nika iToric Orthokeratology iiLens Ukuskena i-Electron Microscopy Imaging Ukusebenzisa imifanekiso yeSEM, uLee et al.yafumanisa ukuba imiphezulu ye-achromatic ye-cosmetic contact lens yayigudileyo kwaye incantsi kuneendawo ezinemibala.
umbala weelensi zoqhagamshelwano
Baye bafumanisa ukuba inani eliphezulu le-Acanthamoeba trophozoites lincanyathiselwe kwiindawo ezirhabaxa ezinombala obala xa kuthelekiswa neendawo ezingenambala, ezigudileyo.
Njengoko imfuno ye-cosmetic contact lens isanda, lo ngumngcipheko omele uxoxwe kunye nezigulana ezinxiba iilensi ezinemibala.
Ngezinto ezintsha ze-lens, ezifana ne-silicone hydrogels, iilensi ezininzi zokudibanisa eziveliswa ngobuninzi zibonelela ngokugqithiswa kwe-oksijini kunokuba kuyimfuneko.Ukuhanjiswa kwe-oksijeni kulinganiswa ngendawo ephakathi ye-optic ye-lens, ngelixa ukuhanjiswa kwe-oxygen kwi-peripheral kuyingxaki.
Uphononongo olwenziwa yiGalas kunye neCopper lusebenzisa iilensi ezikhethekileyo ezenziwe ngokukodwa ngee-pigments ngokusebenzisa indawo ephakathi ye-optical zone ukulinganisa i-oxygen permeability ngokusebenzisa i-pigments. ukhuseleko.RELATED: Ingcaphephe inikezela ngeeMfihlo zokuQhagamshelana neLens Practice Practice
IZIQINISEKISO Nangona ukusilela kwee-lens zoqhagamshelwano eziveliswe ngobuninzi, ukusetyenziswa kwazo kuye kwanda ngokukhawuleza.Eli nqaku lijolise ekuncedeni abaqeqeshi ukuba baqonde ukuba kutheni imfundo iyingxenye ebalulekileyo yokugqoka iilensi zokudibanisa ezinemibala.Kungakhathaliseki ukuba i-cosmetic okanye ukusetyenziswa kwezonyango, imfundo yesigulane kunye nokuqaphela ingozi nceda ukunciphisa iziganeko ezimbi kunye nokuphucula ukhuseleko lweelensi zokudibanisa ezinemibala.
