Ukhathele ukugqoka izibuko nokusebenzisa ama-contact lens? Cishe uyazi kahle inkinga yokushintsha phakathi kwesinye ukuze ubone eduze kwesinye ukuze ubone kude? Mhlawumbe ubulokhu ucabanga ngokuhlinzwa "kwe-laser", noma into efana ne-LASIK, kodwa udokotela wakho ukutshelile ukuthi amandla akho amehlo aphezulu kakhulu noma ngesizathu esithile. Ngakho-ke uma uzibuza ukuthi wenzeni manje, ungakhathazeki. Kukhona enye indlela ephumelelayo yokususa izibuko cishe ngokuphelele. Yilokho esikhuluma ngakho namuhla.
Kuyini i-Refractive Lens Exchange (RLE)?
Kalula nje, i-Refractive Lens Exchange iwukuhlinzwa lapho ilensi yemvelo esweni lakho isuswa khona bese kufakwa ilensi yokwenziwa eyenzelwe ukufanelana nokubona kwakho. Sibiza le lensi yokwenziwa ngokuthi i -Intraocular Lens (IOL) . Cabanga ngakho njengokufaka ilensi encane enamandla afanayo nezibuko zakho noma amalensi okuxhumana unomphela ngaphakathi kweso lakho.
Uma i-IOL isifakiwe esweni lakho, isebenza njengelensi yakho yemvelo. Igxila ukukhanya okungena esweni lakho futhi ikugxilise ngqo ku-retina. Lokhu kukuvumela ukuthi ubone kahle. Abantu abaningi akudingeki bagqoke izibuko ngemva kwalokhu kuhlinzwa. Abanye abantu bangase badinge izibuko kuphela emisebenzini eseduze, njengokufunda incwadi noma iphephandaba.
Lokhu kuyindlela enhle yokwelapha esikhundleni sokuhlinzwa nge-laser njenge-LASIK. Ukuhlinzwa kwe-LASIK kushintsha ukuma kwe-cornea. Kodwa-ke, i-LASIK ayifanele abantu abanenkinga enkulu yokubona noma ezinye izinkinga zamehlo. Uma utshelwe ukuthi awukwazi ukwenza i-LASIK, udokotela wakho angase akuncome ukuhlinzwa kwe-Refractive Lens Exchange.
Ubani lo kuhlinzwa ofaneleka kakhulu?
Udokotela wamehlo uzonquma ukuthi lokhu kuhlinzwa kulungile yini kuwe ngemuva kokuhlolwa kwamehlo akho ngokucophelela. Lokhu kuhlinzwa kuvame ukuba ngcono kubantu abangaphezu kweminyaka engama-40. Lokhu kungenxa yokuthi kuleyo minyaka, abantu baqala ukuba ne-presbyopia, okuwukubona eduze okuvamile okuhambisana nokuguga.
Ake sibone kusukela kuthebula elingezansi ukuthi lokhu kufaneleka kubani nokuthi akufanelani nobani.
| Uma lokhu kuhlinzwa kungaba kuhle kuwe | Izimo lapho lokhu kuhlinzwa kungase kungakufanelekeli khona |
|---|---|
| Uma une-nearbone ebukhali (myopia) noma i-deserte (hyperopia) lokho kwenza i-LASIK ingenzeki. | Uma unesifo esithinta i-cornea yeso. |
| Uma ufuna ukuqeda isidingo sezibuko ngenxa ye-presbyopia, isimo esenzeka ngokuguga. | Uma une-aging-related macular degeneration. |
| Uma udinga ukulungisa i-astigmatism. | Uma une-retinopathy yesifo sikashukela (i-retinopathy ebangelwa isifo sikashukela). |
| Uma kunezinto ezibangela ingozi yokuqhekeka kwe-retinal. |
Uyini umehluko phakathi kokuhlinzwa kwe-cataract nalokhu?
Abantu abaningi badidanisa lokhu kuhlinzwa nokuhlinzwa kwe-cataract. Kokubili kuhilela ukususa ilensi yemvelo yeso bese kufakwa ilensi yokwenziwa (IOL). Kodwa-ke, umehluko omkhulu usesizathwini sokuhlinzwa.
Cabanga ngelensi yakho yamehlo njengelensi yekhamera. Ukushintshaniswa Kwelensi Ebonakalayo kwenziwa ngoba ilensi ilungile, kodwa kunenkinga ngokugxila kwayo. Ukuhlinzwa kwe-cataract kwenziwa ngoba ilensi ngokwayo inamafu futhi ingcolile.
Ake sichaze lo mehluko kabanzi.
| Ukuqhathanisa | Ukushintshaniswa Kwelensi Ebonakalayo (RLE) | Ukuhlinzwa Kwe-Cataract |
|---|---|---|
| Isizathu sokuhlinzwa | Ukulungisa iphutha lokubuyisa amehlo nokukhululeka ezibukweni. | Ukususa ilensi eguqubele ngenxa ye-cataracts nokubuyisela umbono ocacile. |
| Isimo selensi yemvelo | Ilensi icacile , kodwa kukhona iphutha lokugxila. | Ilensi inamafu (amafu). |
Kwenziwa kanjani ukuhlinzwa?
Lokhu kuhlinzwa kuvame ukuthatha imizuzu eyi-15-30. Ngeke ulaliswe ngokuphelele. Uzobe uphapheme, kodwa ngeke uzwe ubuhlungu.
- Isinyathelo 1: Okokuqala, uzonikezwa amaconsi amehlo akhethekile ukuze uqede ukungasebenzi kahle kwamehlo akho. Unganikezwa nemithi yokukugcina uzolile uma kudingeka.
- Isinyathelo sesi-2: Udokotela ohlinzayo ube esesika indawo encane kakhulu lapho kuhlangana khona umhlophe weso kanye ne-cornea, kungaba nge-laser noma nge-blade encane kakhulu.
- Isinyathelo 3: Ithuluzi elibunjwe njengepeni (ithuluzi le-phacoemulsification) lifakwa ngalo msibo, liphule ilensi yakho yemvelo ibe yizicucu ezincane, lizincibilikise, bese lizisusa esweni lakho kusetshenziswa i-vacuum.
- Isinyathelo 4: Ekugcineni, ilensi entsha yokwenziwa (i-IOL) ifakwa nge-incision efanayo bese ibekwa ngaphakathi kwe-capsule yelensi yemvelo.
- Isinyathelo 5: Lo msibo mncane kangangokuthi awudingi ngisho nokuthungwa. Uzozivalela wodwa. Ngemva kokuhlinzwa, kuzobekwa ibhandeji elincane phezu kwawo ukuze kuvikelwe iso.
Kwenzekani ngemva kokuhlinzwa? Kuthatha isikhathi esingakanani ukululama?
Ngemva kokuhlinzwa, uzoqashwa cishe imizuzu engama-30 bese uthunyelwa ekhaya. Kubalulekile ukuthi kube khona umuntu ozokuthatha akuyise ekhaya. Kufanele futhi ube nomuntu ozokuthatha akuyise emtholampilo ngosuku olulandelayo.
Ezinsukwini ezimbalwa zokuqala, kuvamile ukuba nombono ofiphele, ukubona kabili, ukuzwa isihlabathi emehlweni, ukubomvu kwamehlo, namehlo anamanzi. Lezi zimpawu zizophela ezinsukwini ezimbalwa.
Abanye abantu bangase babone izinguquko ezithile ekuboneni kwabo, njengezibani zokukhanya noma ukukhanya okuzungeze izibani zemoto, ikakhulukazi lapho beshayela ebusuku. Lokhu kuvame ukuncipha ngokuhamba kwesikhathi. Khuluma nodokotela wakho ngalokhu kusenesikhathi.
Kungathatha amasonto afika kwangu-8 ukuthi iso lakho liphole ngokuphelele. Kodwa-ke, kufanele ukwazi ukuqhubeka nemisebenzi evamile zingakapheli izinsuku noma amasonto ambalwa. Udokotela wakho uzokweluleka ngokuthi ungashayela nini, uye emsebenzini, ugeze, futhi uzivocavoce nini. Kubalulekile ukusebenzisa amaconsi amehlo njengoba nje udokotela wakho ekuyalele.
Izinzuzo, izingozi kanye nesikhathi sokuthola usizo lwezokwelapha ngokushesha
Izinzuzo eziyinhloko zalokhu kuhlinzwa yilezi:
- Ukukwazi ukwelapha zonke izinhlobo zokukhubazeka kokubona, njengokubona eduze, ukubona kude, kanye ne-astigmatism.
- Ukukwazi ukukhululeka kakhulu ezingilazini (abantu abane kwabahlanu abahlinzwayo abadingi izibuko).
- Asikho isidingo sokukhathazeka ngokuthuthukisa ama-cataract esikhathini esizayo, ngoba ama-cataract akheka kuphela kumalensi emvelo.
Njenganoma yikuphi ukuhlinzwa, kunezingozi ezincane. Inkinga enkulu kakhulu, kodwa engavamile kakhulu, ukuhlukana kwe-retina. Lezi zingozi zingancishiswa ngokuba ukuhlinzwa kwenziwe udokotela ohlinzayo onolwazi.
Bheka udokotela ngokushesha!
Uma uhlangabezana nalezi zimpawu ezilandelayo, zingaba izimpawu zokuqhekeka kwe-retinal. Ngakho-ke, hamba uye eMnyangweni Wezimo Eziphuthumayo (ETU) wesibhedlela esiseduze ngokushesha.
- Ngokungazelelwe ngibona amachashazi amnyama noma izinto ezifana nenethi zintanta phambi kwamehlo (ama-floater amasha).
- Ukukhanya kuyakhanya uma amehlo evulekile noma evaliwe.
- Ukuzizwa sengathi ikhethini elimnyama liwela phezu kombono.
Umlayezo Wokuya Nawe Ekhaya
- I-Refractive Lens Exchange (RLE) iyindlela yokuhlinzwa ephumelela kakhulu yokususa izibuko noma ama-contact lens, ikakhulukazi kulabo abangafaneleki ukuhlinzwa kwe-LASIK.
- Lokhu kuhlukile ekuhlinzweni kwe-cataract. I-RLE yenzelwe abantu abanelensi ecacile kodwa abasabona kahle.
- Khuluma nodokotela wakho mayelana nokukhetha uhlobo lwelensi yangaphakathi kweso (i-IOL) olufanelana kahle nendlela yakho yokuphila nezidingo zakho.
- Ukuze iso liphole ngokushesha ngemva kokuhlinzwa, kubalulekile ukulandela ngokucophelela amaconsi amehlo kanye nemiyalelo enikezwe udokotela.
- Uma uhlangabezana nezimpawu ezifana nokushintsha okuzumayo embonweni noma ukuphinda ukhumbule izinto ezenzeka engqondweni yakho, kubheke njengesimo esiphuthumayo bese ucela iseluleko sezokwelapha ngokushesha.
