Ngaba unomakhulu okanye utatomkhulu ekhaya okhalaza ngelithi amehlo akhe afiphele kwaye yonke into ayifiphele? Okanye ngaba wena ngokwakho ufumana kunzima ukufunda iphephandaba okanye ukujonga ifowuni yakho njengoko ukhula? Isizathu esiphambili soku singaba "zii-cataracts". Ngoko ke namhlanje siza kuthetha ngento encinci kodwa ebaluleke kakhulu efakwa emehlweni ethu ngexesha lotyando. Le yilensi yangaphakathi kweso, okanye njengoko sibiza ngokwezonyango, iiLensi zangaphakathi kweso, okanye iiLensi ze-Intraocular, ngamafutshane.
Zithini ezi IOLs? Ngamafutshane...
Cinga ngeliso lakho njengekhamera elungileyo. Le khamera inelensi yendalo. Umsebenzi wale lensi kukugxila ekukhanyeni okuvela kwizinto esizibonayo nokubonelela ngomfanekiso ocacileyo kwi-retina engaphakathi kweliso. Ngokuhamba kwexesha, ingakumbi njengoko sikhula, le lensi yendalo iqala ukuba namafu kancinci kancinci ize ibe lubisi. Yiloo nto siyibiza ngokuba yi-"cataract."
Khawucinge nje ukuba kwenzeka ntoni ukuba ilensi yekhamera ingcola, ibe nothuli, ikrweleke, kwaye ifiphale? Iifoto ozithathayo azicacanga, akunjalo? Yiloo nto eyenzekayo xa ufumana i-cataract. Ngoko ke, into oyenzayo ngotyando kukususa ilensi yendalo enamafu uze uyitshintshe ngelensi ecacileyo, eyenziweyo enokugcinwa esweni ngonaphakade . Loo lensi yokwenziwa yinto esiyibiza ngokuba yi- IOL .
Ezi lensi ze-IOL azinakulungisa kuphela i-cataracts, kodwa zikwalungisa nezinye iingxaki ezininzi zokubona onokuzilungisa ngeeglasi okanye iilensi zoqhagamshelwano.
- I-Myopia: Ukubona izinto kufutshane ngokucacileyo, kodwa ukubona izinto ezikude ngendlela engacacanga.
- Ukubona izinto ezikufutshane (i-Hyperopia): Ukubona ngokucacileyo xa ukude, kodwa kunzima ukufunda izinto ezikufutshane, ingakumbi iincwadi.
- I-Presbyopia: Yimeko echaphazela abantu abaninzi abaneminyaka engaphezu kwama-40 ubudala, efuna iiglasi ukuze babone kufutshane.
- I-Astigmatism: Imeko apho ukukhanya kungajolisi ndawo inye, nto leyo ebangela umbono ogqwethekileyo, ngenxa yotshintsho oluncinci kwimo yeliso.
Wakuba unezi lensi ze-IOL esweni lakho, zihlala ubomi bakho bonke. Ngoko ke ungakunciphisa kakhulu ukuxhomekeka kwakho kwiiglasi.
Ngubani ofuna ezi lensi ze-IOL?
Amaqela amabini aphambili abantu axhamla kakhulu kwezi lensi ze-IOL.
1. Kwabo bane-cataracts: Ukuba i-cataract ikhule yada yafikelela kwinqanaba lokuba iphazamise umbono wakho, kuya kufuneka isuswe ngotyando. Emva kokususwa, ngokuqinisekileyo ilensi ye-IOL kuya kufuneka ifakwe esweni. Ngaphandle koko, umbono awunakubuyiselwa. Yiyo loo nto uninzi lwee-implants ze-IOL zenziwa eSri Lanka.
2. Kwabo banengxaki yokubona kodwa abafanelekanga utyando olufana neLASIK:Abanye abantu baneengxaki zokubona ezifuna iiglasi, kodwa basenokungakwazi ukwenza utyando lwamehlo nge-laser (LASIK). Kwiimeko ezinjalo, utyando lokutshintshiselana nge-refractive lens, olubandakanya ukususa ilensi yendalo kunye nokufakelwa i-IOL, lunokwenzeka.
Ziziphi iintlobo zeelensi ze-IOL? Yeyiphi efanelekileyo kuwe?
Le yingxaki abantu abaninzi abanayo. Kukho iintlobo ezininzi ze-IOL. Nganye ineengenelo kunye neengxaki zayo. Ngeelensi ezithile, usenokufuna iiglasi kwizinto ezifana nokufunda incwadi okanye iphephandaba. Ezinye iilensi "eziphambili" zinokunciphisa kakhulu ukuthembela kwakho kwiiglasi, kodwa zinokubangela nemiphumo emibi efana ne-glare kunye ne-halos ezijikeleze izibane zemoto xa uqhuba ebusuku.
Kungoko ke, kubaluleke kakhulu ukuthetha nogqirha wakho wamehlo uze ukhethe ilensi efanela indlela yakho yokuphila, iimfuno zakho kunye nezinto ozithandayo.
Ukuze kube lula ukuqonda, makhe sijonge iintlobo eziphambili zeelensi kwitheyibhile.
| Uhlobo lwelensi | Ijongeka intle kakhulu. | Izinto eziphawulekayo/ezingalunganga |
|---|---|---|
| I-Monofocal | Inika umbono ocacileyo kakhulu kumgama omnye kuphela (kude, phakathi, okanye kufutshane). | Ihlala ilungiselelwa ukubona umgama. Emva koko, xa ubona kufutshane (ukufunda, ukufaka intambo kwinaliti) , kufuneka unxibe iiglasi . Olu lolona hlobo lusetyenziswa kakhulu, kwaye lungabizi kakhulu. |
| I-Multifocal | Ibonelela ngombono olungileyo kokubini umgama kunye nokufutshane. | Inciphisa ukuxhomekeka kwiiglasi. Nangona kunjalo, ungabona ukukhanya okanye ukukhanya okujikeleze izibane ebusuku. Kuthatha ixesha ukuba ingqondo iqhele oku. |
| I-EDOF (Ubunzulu Obubanzi Bokugxila) | Ibonelela ngokubona okuhle komgama kunye nomgama ophakathi (umz. isikrini sekhompyutha). | Usenokufuna iiglasi ukuze ubone kufutshane (ufunde umbhalo omncinci). Akukho kukhanya kuncinci kuneelensi ezininzi. |
| I-Toric | Olu asilohlobo olwahlukileyo. Luyilensi ekhethekileyo esetyenziselwa ukulungisa i-astigmatism kubantu abanesi siphene. | I-Astigmatism iyalungiswa, inika umbono ocacileyo nocacileyo. Oku kunokufezekiswa ngeelensi ze-monofocal, multifocal, okanye i-EDOF. |
| Indawo yokuhlala | Isebenza nezihlunu zeliso kwaye izama ukuziqhelanisa nokubona kude nakufutshane, njengelensi yethu yendalo. | Kunciphisa ukuxhomekeka kwiiglasi. Nangona kunjalo, iiglasi zinokufuneka xa ufunda ixesha elide. |
Ezinye iintlobo zeelensi ezikhethekileyo
- Iilensi ezihlengahlengiswayo ngokukhanya (ii-LAL): Ezi zahlukile kancinci. Emva kotyando, ugqirha wakho angasebenzisa uthotho lweendlela ezikhethekileyo zokukhanya kwe-ultraviolet (i-UV) ukutshintsha kancinci amandla ezi lensi ukuze zikunike umbono owufunayo. Ezi nazo zi-monofocal, ngoko ke uya kufuna iiglasi ukuze ubone kufutshane.
- Iilensi zePhakic: Ezi zihlala zisetyenziswa kubantu abancinci. Ilensi yendalo ayisuswa. Endaweni yoko, le lensi ifakwa phambi kwelensi yendalo. Zisetyenziselwa ukulungisa ukubona kufutshane kubantu abangafanelekanga kunyango lwelaser.
Into ebalulekileyo kukuba, akukho nto ibizwa ngokuba "yilensi ilungileyo." Kukho "ilensi ekufaneleyo" kuphela. Kuxhomekeke kwimpilo yamehlo akho, imisebenzi yakho yemihla ngemihla, kunye nolindelo lwakho.
Cinga ngaphambi kokuba uthethe nogqirha wakho.
Ngaphambi kokuba uye kubona ugqirha wakho wamehlo, zibuze le mibuzo. Emva koko uya kuba nombono ocacileyo wento oyifunayo.
- Ngaba ngamanye amaxesha ndiyakuthanda ukunxiba iiglasi? Ukuba kunjalo, ngawaphi amaqhinga? (umz., ukufunda iincwadi nje? Okanye lonke ixesha?)
- Luhlobo luni lombono endiwudingayo ngomsebenzi wam? Ngaba ndijonga ikhompyutha imini yonke? Ngoko ke, kulungile na ukuba ndinxibe iiglasi kuloo msebenzi?
- Ngaba ndihlala ndiqhuba imoto ebusuku?Ngoko ke, ndingaqhela ukubona izangqa ezikhazimlayo zijikeleze izibane?
- Zithini izinto endizithandayo? Ngaba ndingumntu owenza umsebenzi onzima, njengokuthunga okanye ukuzoba? Okanye ndingumntu odlala imidlalo okanye othanda ukuba ngaphandle? Iiglasi ziya kuphazamisana kangakanani nale misebenzi?
- Ingakanani imali endinayo yolu tyando? Kwisibhedlele sikarhulumente, iilensi ze-monofocal zihlala zibonelelwa simahla. Nangona kunjalo, kusenokufuneka uhlawule ngaphezulu iilensi ezikhethekileyo ezifana ne-multifocals. Kwisibhedlele sabucala, amaxabiso ayahluka kakhulu ngokuxhomekeke kuhlobo lwelensi. Yazi oko kwangaphambili.
Ziziphi iingxaki ezinokubakho ezinxulumene nokufakelwa kwe-IOL?
Ukufakelwa kwe-IOL kudla ngokuba lutyando oluphumelelayo kakhulu. Nangona kunjalo, njengalo naluphi na utyando, kukho iingxaki ezingaqhelekanga ezinokwenzeka. Ezi azifanele zoyikwe, kodwa kulungile ukuziqaphela.
- Ukuvulwa kwePosterior Capsular: Oku kukwabizwa ngokuba yi "secondary cataract." Kwiinyanga okanye iminyaka emva kotyando, umaleko omncinci we-opacity uyavela emva kwe-IOL yakho. Oku kuqhelekile kakhulu. Oku kunokubangela ukuba umbono wakho uphinde ube mfiliba kancinci. Kulula kakhulu ukunyanga oku. Ngokwesiqhelo, umaleko ungasuswa ekliniki kwimizuzu embalwa kusetyenziswa i-laser beam, ucoce umbono wakho.
- Ukuqhekeka kwe-IOL: Ilensi efakelweyo iyasuka endaweni yayo. Oku kuyinto engaqhelekanga. Umngcipheko uphezulu kancinci kubantu abaneengxaki ezithile zamehlo okanye abo baye bahlaselwa kakhulu liliso.
- I-UGH syndrome (i-Uveitis-glaucoma-hyphema syndrome): Yimeko engaqhelekanga kakhulu ebangelwa yilensi ye-IOL ebetha iindawo ezithile zeliso, njenge-iris.
- IOL opacification: Ukufiphala kwelensi yokwenziwa ngokwayo. Oku kunqabile kakhulu kwiilensi zanamhlanje.
- Ukumangaliswa kokuKhangela: Emva kotyando, umbono wakho usenokungacaci njengoko wena nogqirha wakho benilindele. Kwimeko enjalo, ugqirha wakho uza kuchaza iindlela onokukhetha kuzo, njengokwamkela umbono njengoko unjalo, okanye ukusebenzisa iiglasi, unyango lwelaser, okanye ukutshintshwa kwe-IOL.
Ukuba unenkxalabo ngayo nayiphi na kwezi, thetha nogqirha wakho ngaphambi kotyando. Uza kukuchazela iingozi ngokusekelwe kwimbali yakho yezonyango kunye nempilo yamehlo.
Umyalezo Wokuya Ekhaya
- I-IOL (I-Intraocular Lens) yilensi yokwenziwa efakwa esweni lakho ukuze ithathe indawo yelensi yakho yendalo enamafu ngexesha lotyando lwe-cataract.
- Kukho iintlobo ezahlukeneyo ze-IOL, ezifana ne-monofocal (yomgama omnye), i-multifocal (yomgama nokufutshane), i-EDOF, kunye ne-toric (yoku-astigmatism).
- Ukukhetha "ilensi ekufaneleyo" kubaluleke ngakumbi kunokukhetha "ilensi engcono" .
- Thetha ngokukhululekileyo nogqirha wakho wamehlo malunga nendlela ophila ngayo (umsebenzi, izinto ozithandayo, ukuqhuba) kunye nolindelo lokubona.
- Qonda iingenelo kunye neengxaki zohlobo ngalunye lwelensi (umz., ukukhanya ebusuku, isidingo seeglasi).
- Nangona iingxaki ezinokubakho zinqabile kakhulu, kubalulekile ukuba uzazi kwaye ubuze ugqirha wakho nayiphi na imibuzo onokuba nayo.
