Ngaba udiniwe kukunxiba iiglasi nokusebenzisa iilensi zonxibelelwano? Mhlawumbi uyazi kakuhle ingxaki yokutshintsha phakathi kwenye ukuze ubone kufutshane nenye ukuze ubone umgama? Mhlawumbi ubucinga ngotyando "lwe-laser", okanye into efana ne-LASIK, kodwa ugqirha wakho ukuxelele ukuba amandla akho amehlo aphezulu kakhulu okanye ngenxa yesizathu esithile. Ngoko ke ukuba uyazibuza ukuba wenze ntoni ngoku, ungakhathazeki. Kukho enye indlela esebenzayo yokususa iiglasi phantse ngokupheleleyo. Yiloo nto sithetha ngayo namhlanje.
Yintoni iRefractive Lens Exchange (RLE)?
Ngamafutshane, iRefractive Lens Exchange lutyando apho ilensi yendalo eliso lakho isuswa khona ize ithathelwe indawo yilensi yokwenziwa eyenzelwe ukufanisa umbono wakho. Le lensi yokwenziwa siyibiza ngokuba yiIntraocular Lens (IOL) . Cinga ngayo njengokuba nelensi encinci enamandla afanayo neeglasi zakho okanye iilensi zoqhagamshelwano ezifakwe ngokusisigxina ngaphakathi kweliso lakho.
Xa i-IOL ifakiwe elisweni lakho, isebenza njengelensi yakho yendalo. Igxila ukukhanya okungena elisweni lakho kwaye ikujolise ngqo kwi-retina. Oku kukuvumela ukuba ubone ngokucacileyo. Abantu abaninzi akufuneki banxibe iiglasi emva kolu tyando. Abanye abantu banokufuna iiglasi kuphela kwimisebenzi ekufutshane, njengokufunda incwadi okanye iphephandaba.
Olu lolunye uhlobo olufanelekileyo endaweni yotyando lwelaser olufana neLASIK. Utyando lweLASIK lutshintsha imo ye-cornea. Nangona kunjalo, iLASIK ayifanelekanga kubantu abanengxaki yokubona kakhulu okanye ezinye iingxaki zamehlo. Ukuba uxelelwe ukuba awunakwenza iLASIK, ugqirha wakho unokucebisa utyando lweRefractive Lens Exchange.
Ngubani olungele olu tyando?
Ugqirha wamehlo uza kugqiba ukuba olu tyando lukulungele na emva kokuhlolwa kakuhle kwamehlo akho. Olu tyando ludla ngokuba lolona lufanelekileyo kubantu abangaphezu kweminyaka engama-40 ubudala. Oku kungenxa yokuba kuloo minyaka, abantu baqala ukuba ne-presbyopia, into eqhelekileyo eyenzeka xa bekhula.
Makhe sibone kwitheyibhile engezantsi ukuba ngubani ofanelekileyo kwaye ngubani ongafanelanga.
| Xa olu tyando lunokuba lufanelekile kuwe | Iimeko apho olu tyando lusenokungakulungeli |
|---|---|
| Ukuba une-nearbone ebukhali (myopia) okanye i-hyperopia (hyperopia) oko kwenza i-LASIK ingenzeki. | Ukuba unemeko echaphazela i-cornea yeliso. |
| Ukuba ufuna ukulahla iiglasi ngenxa ye-presbyopia, imeko eyenzeka xa ukwaluphala. | Ukuba une-age-related macular degeneration. |
| Ukuba ufuna ukulungisa i-astigmatism. | Ukuba une-diabetesic retinopathy (i-retinopathy ebangelwa sisifo seswekile). |
| Ukuba kukho izinto ezinokubangela ukuba i-retina ingasebenzi kakuhle. |
Yintoni umahluko phakathi kotyando lwe-cataract kunye noku?
Abantu abaninzi babhidanisa olu tyando notyando lwe-cataract. Zombini ziquka ukususa ilensi yendalo yeliso uze ufake ilensi yokwenziwa (IOL). Nangona kunjalo, umahluko omkhulu usekwe kwisizathu sotyando.
Cinga ngelensi yakho yeliso njengelensi yekhamera. Ukutshintshwa kwelensi evuselelayo kwenziwa kuba ilensi ilungile, kodwa kukho ingxaki ngokugxila kwayo. Utyando lwe-cataract lwenziwa kuba ilensi ngokwayo inamafu kwaye ingcolile.
Masichaze ngakumbi lo mahluko.
| Uthelekiso | Utshintshiselwano lweLensi eziBonakalayo (RLE) | Utyando lweCataract |
|---|---|---|
| Isizathu sotyando | Ukulungisa impazamo yokungahoyi kakuhle nokukhululeka kwiiglasi. | Ukususa ilensi eguqubele ngenxa ye-cataracts nokubuyisela umbono ocacileyo. |
| Imeko yelensi yendalo | Ilensi icacile , kodwa kukho impazamo yokugxila. | Ilensi inamafu (inefu). |
Lwenziwa njani utyando?
Olu tyando ludla ngokuthatha malunga nemizuzu eli-15-30. Awuyi kuphelelwa yintlungu ngokupheleleyo. Uza kube uvukile, kodwa awuyi kuva ntlungu.
- Inyathelo 1: Okokuqala, uza kunikwa amathontsi akhethekileyo amehlo ukuze angabi nanto. Unganikwa namayeza okukugcina uzolile ukuba kuyimfuneko.
- Inyathelo lesi-2: Emva koko ugqirha wenza umngxuma omncinci kakhulu apho umhlophe weliso kunye ne-cornea kudibana khona, nokuba usebenzisa i-laser okanye i-blade encinci kakhulu.
- Inyathelo lesi-3: Isixhobo esimile okwepeni (isixhobo se-phacoemulsification) sifakwa ngolu qweqwe, siqhekeze ilensi yakho yendalo ibe ziingceba ezincinci, sizinyibilikise, size sizisuse esweni lakho sisebenzisa i-vacuum.
- Inyathelo lesi-4: Okokugqibela, ilensi entsha yokwenziwa (i-IOL) ifakwa nge-incision efanayo ize ibekwe ngaphakathi kwi-capsule yelensi yendalo.
- Inyathelo lesi-5: Olu tyando luncinci kangangokuba aludingi nokuthungwa. Luza kuvala lodwa. Emva kotyando, kuya kubekwa ibhandeji elincinci phezu kwalo ukukhusela iliso.
Kwenzeka ntoni emva kotyando? Kuthatha ixesha elingakanani ukuze umntu aphile?
Emva kotyando, uza kuhlolwa imizuzu engama-30 uze emva koko uthunyelwe ekhaya. Kubalulekile ukuba kubekho umntu oza kukusa ekhaya. Kufuneka ube nomntu oza kukusa ekliniki ngosuku olulandelayo.
Kwiintsuku ezimbalwa zokuqala, kuyinto eqhelekileyo ukuba nombono ofipheleyo, umbono ophindwe kabini, ukuziva ngathi kukho isanti emehlweni, amehlo abomvu, namehlo anamanzi. Ezi mpawu ziya kuphela kwiintsuku ezimbalwa.
Abanye abantu banokubona utshintsho oluthile ekuboneni kwabo, njengee-halos okanye ukukhanya okujikeleze izibane zemoto, ingakumbi xa beqhuba ebusuku. Oku kudla ngokuphela ngokuhamba kwexesha. Thetha nogqirha wakho ngale nto kwangaphambili.
Kungathatha ukuya kuthi ga kwiiveki ezisi-8 ukuba iliso lakho liphole ngokupheleleyo. Nangona kunjalo, kufuneka ukwazi ukuqalisa imisebenzi eqhelekileyo kwiintsuku okanye iiveki ezimbalwa. Ugqirha wakho uza kukunika ingcebiso malunga nokuba ungaqhuba nini, uye emsebenzini, uhlambe, kwaye uzilolonge nini. Kubalulekile ukusebenzisa amathontsi amehlo njengoko ugqirha wakho ekuyalele.
Iingenelo, iingozi kunye nexesha lokufuna unyango ngokukhawuleza
Iingenelo eziphambili zale tyando zezi:
- Ukukwazi ukunyanga zonke iintlobo zokuphazamiseka kokubona, njengokubona okukufutshane, ukubona kude, kunye ne-astigmatism.
- Ukukwazi ukukhululeka kakhulu kwiiglasi (abantu aba-4 kwaba-5 abenza utyando abazidingi iiglasi).
- Akukho mfuneko yokukhathazeka malunga nokukhula kwe-cataracts kwixesha elizayo, kuba i-cataracts yenzeka kuphela kwiilensi zendalo.
Njengakwezinye iintlobo zotyando, kukho iingozi ezincinci. Eyona ngxaki inzima, kodwa ingaqhelekanga, kukuqhekeka kwe-retina. Ezi ngozi zingancitshiswa ngokwenziwa kotyando ngugqirha onamava.
Bona ugqirha ngoko nangoko!
Ukuba ufumana ezi mpawu zilandelayo, zinokuba ziimpawu zokuqhekeka kwe-retina. Ngoko ke, yiya kwiSebe lezeMpilo eziNgxamisekileyo (ETU) lesibhedlele esikufutshane ngoko nangoko.
- Ngequbuliso ndibona amachaphaza amnyama okanye izinto ezifana nenethi zintanta phambi kwamehlo (ii-floaters ezintsha).
- Ukukhanya okukhanyayo xa amehlo evulekile okanye evaliwe.
- Ndivakalelwa ngathi kukho ikhethini emnyama ewela phezu kombono.
Umyalezo Wokuya Ekhaya
- I-Refractive Lens Exchange (RLE) lutyando oluphumelele kakhulu lokususa iiglasi okanye iilensi zoqhagamshelwano, ingakumbi kwabo bangafanelekanga kutyando lwe-LASIK.
- Oku kwahlukile kutyando lwe-cataract. I-RLE yenzelwe abantu abanelensi ecacileyo kodwa abasaboni kakuhle.
- Thetha nogqirha wakho malunga nokukhetha uhlobo lwelensi yangaphakathi kweso (IOL) olufanele indlela yakho yokuphila neemfuno zakho.
- Ukuze iliso liphole ngokukhawuleza emva kotyando, kubalulekile ukulandela ngokungqongqo amaconsi eliso kunye nemiyalelo enikwe ngugqirha.
- Ukuba ufumana iimpawu ezifana nokutshintsha ngequbuliso kombono okanye ukuphinda ubuye engqondweni, cinga ukuba yingxamiseko kwaye ufune ingcebiso yezonyango ngoko nangoko.
