I-ltraocular lenses (i-IOL) ziyi-lens ze-prosthetic ezisetyenziselwa ukutshintsha iilensi zemvelo kwi-intraocular operation lens, ezifana nokuhlinzwa ukuze kususwe i-cataract. Ngethuba lotyando lwe-cataract , i-lens yemvelo isuswe kwaye i-lens ecacileyo ifakwe kwindawo yayo. Kwixesha elidlulileyo, izigulane ze-cataract zanikezwa i-lens e-monofocal implantable eyenzelwe ukuphucula umbono womgama okanye umboniso osondeleyo, kodwa hhayi zombini.
Uninzi lwezigulane zakhetha ukuba izimpembelelo zazo zigxile kumgama. Ukufunda iziglasi okanye i- bifocals kwakudingeka ukuba kube lula kunye nokugxila. Namhlanje, i-lentile ye-intraocular i-lens iqala ukufaka indawo ye-lens intraocular lens ngoba ivumela ukulungiswa kuyo yonke imimandla, ukwenza umbono njengendalo. Ezi iilensi zihlala zibizwa ngokuba yi-presbyopia-ilungisa i-IOL.
I-Presbyopia yokulungisa i-IOL ayifumanekanga njengemfuneko yempilo, ngoko ke ayidlalwa yi-Medicare okanye nezinye iinkampani zomshuwalense yezempilo. Kodwa izimpembelelo ze-monofocal zendabuko, kunjalo, zihlala zihlanganiswa yi-inshurensi kunye ne-Medicare. Ngenxa yoko, abaninzi abagqirha bahlawula umrhumo okanye umrhumo owenziwe kwi-cataract. Le ntlawulo ibanga ukusuka kwi-$ 1,200 ukuya kuma-3 500. I-teknoloji kwi-presbyopia-ukulungisa i-IOL iya kutshintsha ngokukhawuleza. Iintlobo ezahlukileyo ezikhoyo ngoku zihlala zihlukaniswe ngamaqela amabini, ukuhlala kwii-IOL kunye ne-IOLs ezininzi.
Ukuhlala kwiIOLs
Ezi ii-IOL zenzelwe ukusebenza kunye nomzimba we-ciliary, umsila omncinane ngaphakathi kwiso. Umzimba we-ciliary uyinxalenye yesicwangciso sethu sokuqhelanisa esicacileyo esilisebenzisa kuyo yonke imihla yethu. Esi sikontraka ngasinye sizama ukugxila kwinto ebudeni obufutshane. Xa zivumelwano, ivumela i-lens yethu yemvelo ukutshintsha isimo, ukunyusa amandla ukwenzela ukuba kufakwe izinto ezikufutshane.
Xa kuhlala ii-IOL zifakwe kwijiso, izivumelwano zesikhumba ze-ciliary kwaye zivumela i-IOL ukuba ihambe kwaye ishintshe isikhundla. Ezi ii-IOL zinamaqhina amancinci avumelekileyo kule ntlangano ukuba yenze icace ngokusondeleyo, kumbono ophakathi kunye nomgama. Ukuhlala kwiIOLs ngokubanzi ukulinganisa umboniso oqhelekileyo kwaye unomlinganiselo omncinci wezinto ezibonakalayo ezingafunekiyo, ezifana ne-glare okanye i-halos. Nangona kunjalo, abanako ukuhambisa ngokwaneleyo ekujoliswe kumandla kwezinye izigulane.
U mzekelo
I-Crystalens i-IOL : Ekuqaleni i-FDA-yamkelwe ngo-2004, i-Crystalens yaphucula inguqu yayo yokuqala kwaye yafumana imvume yo-FDA ngo-2008. Ucwaningo lwe-FDA lubonisa ukuba izigulane ezingama-80 ezisebenzise i-Crystalens IOL zingabona i-20/20 ngasekupheleni kweenyanga ezine. UCriststalen uhlala enika umboniso omncinane kumgama kunye nemimandla ephakathi, kwaye lukhethi olukhethekileyo kubantu abenza umsebenzi osondeleyo okanye izinto zokuzilibazisa.
Ezinye ii-IOL ezihlala kuzo (kusekho kwisigaba sokuphanda):
- I synchrony
- FlexOptic
- Smart
- FluidVision
- TetraFlex
Ii-IOL
Ezi iilensi zenzelwe ukuvumela umgama, ophakathi kunye kunye nokugxininisa kwaye azixhomekeke kumzimba we-ciliary muscle. Uninzi lwama-lensi lunalo uhlobo oluthile lweendandatho ezigxilwe kumhlaba ovumela imifanekiso kuyo yonke imida ukuba igxile kwi- retina .
Ngenxa yoko, kuthatha ixesha elide ukuba abantu bavumelane nabo. Amandla okugxilwa anikezelwa ngamalensi ahluke kunokuba kugxininiswe ngokuqhelekileyo abantu abaninzi ababenabo ngexesha lokuphila kwabo abadala. Ngoko ke, ingqondo kufuneka ivumelane nale ndlela entsha yokugxila. Nangona kunjalo, basebenze ngokumangalisayo.
U mzekelo
- I-ReZoom : isebenzisa iindawo ezi-5 ezihlukeneyo zeengcingo ezibonakalayo emkhatsini we-lens ukubonelela ngokusondeleyo, kumbono ophakathi kunye nomgama
- I-Tecnis Multifocal : ithathwa ngokuba yi "I-I-diffractive" ye-IOL, equkethe iindandatho ezahlukileyo ezongezelela ubude obude bomda we-lens; Uphucula umbono wobusuku kwaye unciphise uxhomekeke kubukhulu bomfundi
- UKUQALA : usebenzisa iteknoloji exhomekeke kubukhulu bomfundi ukubonelela ngembonakalo ecacileyo kuyo yonke imimandla, kunye nenketho efana neyokuphucula ukuhamba kwebusuku kunye nokunciphisa ukukhanya okungafunekiyo kunye ne-halos
Ukufumana ukuba yeyiphi i-lens engcono kuwe, kukulungele ukuthetha nodokotela wakho. Uninzi lwagqirha lugqirha luza kugqiba intetho exoxa malunga nendlela yokuphila, umsebenzi kunye nendlela osebenzisa ngayo amehlo akho ngemihla ngemihla ukukunceda ukhethe i-lens ukuze ifanelane nawe.
