Ngaba nawe uvakalelwa kukuba umbono wakho uya ufiphala njengoko ukhula? Okanye udiniwe kukunxiba iiglasi? Mhlawumbi ugqirha wakho ukuxelele ukuba kufuneka ufake ilensi yakho endaweni yayo. Abantu abaninzi bayoyika kancinci xa besiva oku, becinga, "Kuza kwenzeka ntoni emehlweni akho?" Kodwa eneneni ayoyiki njengoko ucinga. Olu lutyando oluqhelekileyo kakhulu olwenziwa ngempumelelo kwihlabathi liphela. Namhlanje, masithethe ngokuba luyintoni olu tyando lokufaka ilensi endaweni yayo, lwenziwa njani, kwaye kwenzeka ntoni emva kwalo, konke ngokulula.
Kuthetha ukuthini ngokwenene ukutshintsha ilensi yeliso?
Ngamafutshane, oku kuquka ukususa ilensi yendalo engaphakathi kweliso lakho uze uyifake ilensi yokwenziwa. Kufana nokutshintsha ilensi ekwikhamera.
Ngaphakathi kwamehlo ethu, ngasemva kwe-cornea, kukho ilensi yendalo . Oku kucacile kwaye kubonakala ngokucacileyo. Umsebenzi ophambili wale lensi kukugxila ukukhanya okuvela kwizinto esizibonayo kwi-retina engaphakathi kweliso, ukuze sibone ngokucacileyo.
Kodwa ngamanye amaxesha, iingxaki zinokuvela ngale lensi yendalo. Kwiimeko ezinjalo, ugqirha wamehlo ususa ilensi yakho yendalo aze ayifake ilensi yokwenziwa (Intraocular Lens - IOL) . Ezi lensi zokwenziwa zenziwe ngezinto ezingenabungozi ezifana ne-acrylic okanye i-silicone. Zigxila ekukhanyeni njengelensi yendalo kwaye zikunceda ubone ihlabathi ngokucacileyo.
Ngokubanzi kukho iintlobo ezimbini eziphambili zotyando ezithatha indawo yelensi yeli liso.
- Utyando lweCataract
- Utshintshiselwano lweLensi eziBonakalayo (Utshintshiselwano lweLensi eziBonakalayo)
Masijonge ezi zimbini ngokwahlukeneyo.
Utyando lweCataract
Olu lolona tyando luqhelekileyo esikhe seva ngalo sonke. Njengoko sikhula, ngesiqhelo emva kweminyaka engama-40, ilensi yendalo ecacileyo emehlweni ethu iqala ukuba namafu kancinci kancinci ize ibe ngathi lubisi . Oku sikubiza ngokuba yi-cataract . Kufana neglasi ecacileyo eba ngumnkungu ngokuhamba kwexesha.
Xa le cataract iqala ukwakheka, izinto ziba luzizi, imibala ayibonakali ngokucacileyo, kwaye kuba nzima ukuqhuba ebusuku. Ngoko ke xa iqala ukuphazamisana nemisebenzi yakho yemihla ngemihla, ugqirha uya kucebisa ukuba ususe le lens enamafu kwaye ufake ilens entsha, ecacileyo yokwenziwa. Oku kubizwa ngokuba lutyando lwe-cataract.
Utshintshiselwano lweLensi eziBonakalayo
Oku kwahlukile kancinci. Kolu tyando, ilensi yakho yendalo ayisuswa kuba inamafu. Apha, ilensi yakho yendalo icacile . Kodwa utyando lwenzelwe ukulungisa iimpazamo zakho zokuhombisa , oko kuthetha ukuba awukwazi ukubona kude okanye kufutshane.
Ngamafutshane, olu lutyando lokususa iiglasi okanye iilensi zoqhagamshelwano. Olu lukhetho olufanelekileyo kwabo bangenakukwazi ukwenza utyando lokulungisa umbono olufana neLASIK okanye iPRK.
| Uphawu | Utyando lweCataract | Utshintshiselwano lweLensi eziBonakalayo (Utshintshiselwano lweLensi eziBonakalayo) |
|---|---|---|
| Isizathu esiphambili sotyando | Ukususwa kwelensi yendalo eguquguqukayo (ibe mhlophe) njengoko ikhula. | Ukunciphisa ukuxhomekeka kwiiglasi okanye kwiilensi zoqhagamshelwano (ukulungisa ukubona kude/ukubona kufutshane). |
| Imeko yelensi yendalo ngaphambi kotyando | Ayicacanga, ifana nobisi. | Kucacile, kodwa kukho impazamo ebonakalayo. |
Ziziphi iintlobo zeelensi zangaphakathi kweso (ii-IOL)?
Ngoku usenokuba uzibuza, "Ngaba ilensi iyafana kubo bonke abantu?" Hayi, akunjalo. Kukho iintlobo ezahlukeneyo zeelensi zangaphakathi kweso (ii-IOL) onokukhetha kuzo ngokuxhomekeke kwiimfuno zakho, imeko yamehlo, kunye nendlela yokuphila. Uhlobo ngalunye luneengenelo kunye neengxaki zalo. Kukho iintlobo ezintathu eziphambili zeelensi.
1. Iilensi zeMonofocal: Ezi zezona ntlobo zeelensi zisetyenziswa kakhulu neziqhelekileyo. Ezi lensi zinokubonelela ngombono ocacileyo kumgama omnye kuphela. Oogqirha badla ngokulungisa ezi lensi ukuze ukwazi ukubona ngokucacileyo kumgama . Oku kuthetha ukuba unokubona izinto zikude (njengokubukela iTV okanye ukuqhuba) ngokucacileyo ngaphandle kweeglasi, kodwa kuya kufuneka unxibe iiglasi xa usebenza kufutshane (njengokufunda incwadi okanye ukusebenzisa ifowuni yakho) .
2. Iilensi zeMultifocal: Ezi zifana neeglasi ze-bifocal. Ezi lensi zibonelela ngokubona umgama kunye nomgama okufutshane .Zibonelela ngokubona okucacileyo. Ke ngoko, kwiimeko ezininzi, ungakhululeka ngokupheleleyo ekusebenziseni iiglasi xa unxibe ilensi efana nale. Nangona kunjalo, ezi zibiza kancinci kuneelensi ze-monofocal. Abanye abantu banokufumana iziphumo ebezingalindelekanga ezifana nokuqaqamba kwezibane ebusuku.
3. Iilensi zeToric: Ezi zenzelwe ngokukodwa abantu abanengxaki yokubona ebizwa ngokuba yi -astigmatism . I-Astigmatism yimeko apho i-cornea yeliso ingangqukuvanga ngokugqibeleleyo, kodwa inde, njengebhola yombhoxo. Oku kunokubangela umbono ofipheleyo. Ngoko ke ukuba une-cataracts kunye ne-astigmatism, ukufumana ilensi yetoric kunokukunceda ulungise zombini ezi ngxaki ngaxeshanye.
Kungcono ukuxoxa ngohlobo lwelensi olulungele wena nogqirha wakho wamehlo. Uza kuhlola amehlo akho, axoxe ngeemfuno zakho, aze akunike isisombululo esifanelekileyo.
Ndingazi njani ukuba olu tyando lufanelekile kum?
Kukho izinto ezininzi ezithatha isigqibo sokuba olu tyando lukulungele na. Akunyanzelekanga ukuba wenze esi sigqibo wedwa, ugqirha wakho uza kuziqwalasela zonke ezi zinto aze akunike iingcebiso.
- Impilo yamehlo akho: Kubalulekile ukwazi ukuba unezinye izifo zamehlo (ezifana ne-glaucoma).
- Ukucaca kombono wakho: Indlela umbono wakho oye wonakala ngayo kunye nendlela obuchaphazela ngayo ubomi bakho bemihla ngemihla.
- Impilo yakho iyonke: Nokuba unezinye izifo, ezifana nesifo seswekile okanye uxinzelelo lwegazi oluphezulu, nokuba ziyalawuleka na.
- iminyaka yakho.
Emva kokuqwalasela konke oku, ugqirha uza kukuchazela iingenelo zotyando kunye neengozi ezincinci ezinokubakho.
Lwenziwa njani utyando? Ngaba kufuneka ndoyike?
Kulapho abantu abaninzi bayoyika khona. Kodwa akukho sizathu sokoyika. Olu tyando lukhawuleza kakhulu, ludla ngokugqitywa ngemizuzu eli-15 ukuya kwengama-30 .
Awuyi kuva ntlungu ngexesha lotyando. Oku kungenxa yokuba amaconsi amehlo aza kufakwa emehlweni akho ngaphambi kokuba utyando luqale. Uza kunikwa neyeza lokunciphisa ixhala kunye noxinzelelo lwakho. Oku kuya kukunceda uphumle.
Emva kotyando, iqela lezonyango liza kukujonga iiyure ezimbalwa lize likuthumele ekhaya. Kodwa khumbula, awuyi kukwazi ukuqhuba ngaloo mini . Ngoko ke kubalulekile ukuba nomntu oza kukusa ekhaya. Kuqhelekile ukuba umbono wakho ungabonakali kakuhle emva kotyando.
Olu lutyando olungenabungozi kangako . Ugqirha wenza lonke utyando ngokusika okuncinci kakhulu elisweni . Ukusika kuncinci kangangokuba kuyaziphilisa ngokwako .Awudingi nokuthungwa.
Kwenzeka ntoni ngexesha lotyando inyathelo ngenyathelo
Le nkqubo ibizwa ngokuba yi -phacoemulsification . Nangona igama lisenokuvakala liyinkimbinkimbi kancinci, okunye kulula kakhulu.
1. Okokuqala, ugqirha ufaka isixhobo esincinci esweni ngaloo mngxuma mncinci.
2. Emva koko, usebenzisa imisebe yelaser okanye amaza esandi asebenza rhoqo (i-ultrasound), ilensi yakho yendalo enamafu iyaqhekeka ibe ziingceba ezincinci kakhulu ize inyibilike.
3. Okulandelayo, iziqwenga zelensi ezinyibilikisiweyo zikhutshwa ngononophelo ngesixhobo esifana nesicoci se-vacuum.
4. Ngoku indawo apho ilensi yendalo yayikhona ayinanto. Kuloo ndawo ingenanto, ngaloo mngxuma mncinci, ilensi yokwenziwa egobileyo `(IOL)` ifakwa. Nje ukuba ingene ngaphakathi kweliso, iyakhula ngokuzenzekelayo ize ihlale endaweni yayo.
Yiyo loo nto kuphela. Le yinkqubo efanayo eyenzeka kutyando lwe-cataract kunye notyando lokulungisa umbono. Umahluko kuphela kukuba kutyando lwe-cataract, ilensi enamafu iyasuswa, ngelixa kwelinye, ilensi ecacileyo iyasuswa.
Kuthatha ixesha elingakanani ukuphola emva kotyando?
Kungathatha iiveki ezisibhozo ukuba iliso lakho liphole ngokupheleleyo. Kodwa oko akuthethi ukuba kufuneka uhlale ebhedini iiveki ezisibhozo. Ungaqhubeka nemisebenzi yakho emininzi yesiqhelo kwiintsuku ezimbalwa emva kotyando.
Ugqirha wakho uza kukunika iintlobo ezahlukeneyo zamathontsi amehlo oza kuwasebenzisa. Kubaluleke kakhulu ukuwafaka emehlweni akho njengoko kuyalelwe, ngexesha elifanelekileyo. Kufuneka uqaphele ukuba ungafumani manzi okanye uthuli emehlweni akho. Akulunganga ukuhlikihla amehlo akho. Ugqirha wakho uza kukunika imiyalelo ethile yokuba ungaqhuba nini okanye wenze umsebenzi onzima kwakhona.
Lukhuselekile kangakanani olu tyando? Zithini iingozi zalo?
Njengakwezinye iintlobo zotyando, kukho iingozi ezincinci kakhulu. Kodwa eneneni, utyando lwe-cataract luyinkqubo ekhuselekileyo kakhulu . Uphando lufumanise ukuba ama-98% abantu abenza utyando lwe-cataract abafumani ngxaki zinkulu .
Kukho iingxaki ezimbalwa ezingaqhelekanga kakhulu ezinokwenzeka, uninzi lwazo lunokunyangeka lula kwaye lunyangwe ngoogqirha.
- Ukopha ngaphakathi kweliso
- Ukuba nosulelo
- Ukudumba (ukudumba, ukuba bomvu)
- I-Glaucoma (uxinzelelo lwamehlo olongezelelekileyo)
- I-Posterior Capsular Opacification - Oku kukwabizwa ngokuba yi-"secondary cataract". Oku kungalungiswa kwimizuzu embalwa ngonyango lwe-laser.
- Ukuhlukaniswa kweRetinal
- Ukulahlekelwa ngumbono (oku kunqabile kakhulu )
Kubalulekile ukuthetha nogqirha wakho malunga nomngcipheko wakho ngokusekelwe kwimeko yamehlo akho kunye nezinye iimeko zempilo.
Le lensi intsha yoqhagamshelwano iza kuhlala ixesha elingakanani?
Nazi iindaba ezimnandi! Le lensi yokwenziwa (IOL) oyifakileyo elisweni lakho yenzelwe ukuhlala ubomi bakho bonke . Ihlala ihleli. Akufuneki uyitshintshe ngokuphindaphindiweyo.
Nangona kunjalo, kwiimeko ezingaqhelekanga, abanye abantu banokufuna ukutshintsha iilensi zabo. Umzekelo:
- Ukuba kukho nayiphi na ingxaki ngelensi efakiweyo.
- Ukuba awukwazi ukunyamezela iziphumo ebezingalindelekanga zezinye iintlobo zeelensi, ezifana nokukhazimla.
- Ukuba ufuna ilensi yamandla ahlukileyo ukuze wenze umbono wakho ucace ngakumbi.
Ixabisa malini le nto?
Ixabiso lolu tyando liyahluka ngokuxhomekeke kwizinto ezahlukeneyo.
- Isizathu sotyando: Ukuba utyando lwe-cataracts, uninzi lwezicwangciso ze-inshorensi yezempilo ziya kuyihlawulela loo nto. Nangona kunjalo, ukuba ulwenza ukuze kulungiswe umbono wakho (i-Refractive Lens Exchange), ezinye izicwangciso ze-inshorensi zisenokungalugubungeli.
- Uhlobo lwelensi (IOL) olukhethayo: I-inshurensi idla ngokugubungela kuphela iindleko zeelensi ze-monofocal ezisisiseko. Ukuba ukhetha ilensi "yeprimiyamu", efana ne-multifocal okanye i-toric, kunokufuneka uhlawule imali eyongezelelweyo ngayo.
Kungoko ke, kubaluleke kakhulu ukuthetha nogqirha wakho kunye nenkampani yakho yomshuwalense malunga neendleko ezifunekayo ngaphambi kokuba ucwangcise utyando lwakho.
Utyando lwe-cataract luyinkqubo ephumelele kakhulu enokutshintsha ubomi bakho, icoce umbono wakho, kwaye ikuncede ulahle iiglasi. Akukho nto yokoyika. Eyona nto ibalulekileyo kukuxoxa ngayo yonke imibuzo yakho kunye noloyiko lwakho nogqirha wakho, uxelelwe ngayo yonke into, kwaye ujongane notyando ngengqondo ezolileyo.
Umyalezo Wokuya Ekhaya
- Utyando lwe-cataract lolunye lolona tyando luqhelekileyo, lukhuselekileyo, kwaye lukhawuleza kakhulu emhlabeni. Musa ukoyika.
- Oku kwenziwa ikakhulu ukususa i-cataracts (ilensi efipheleyo) okanye ukulungisa ukungasebenzi kakuhle kokubona (ukubona kude/ukubona kufutshane).
- Kukho iintlobo ezahlukeneyo zeelensi zangaphakathi kweso (ii-IOL) ezifakwe esweni lakho. Thetha nogqirha wakho malunga nelensi efanelekileyo kwiimfuno zakho.
- Nangona ukuchacha emva kotyando kukhawuleza, kubaluleke kakhulu ukulandela imiyalelo yezonyango, ingakumbi ukusetyenziswa kwamaconsi emehlweni, ngokuchanekileyo.
