Ukhathele ukugqoka izibuko nokushintsha ama-contact lens njalo ekuseni nakusihlwa? Ukhathele ukuvuka ekuseni ubone umhlaba ufiphele? Khona-ke kumelwe ukuthi uzwile igama elithi 'LASIK'. Abantu abaningi bakubheka njengeqhinga lomlingo lokuhlanza umbono wabo. Ngakho-ke, namuhla sizoxoxa ngalokhu kuhlinzwa kwe-LASIK, iqiniso noma cha, izinzuzo kanye nokungalungi kwayo, nokuthi kufanele yini kuwe, kalula nje, njengokungathi sikhuluma nomngane.
Kalula nje, iyini i-LASIK?
I-LASIK iwukuhlinzwa okusebenzisa ubuchwepheshe be-laser obuthuthukisiwe ukulungisa umbono wakho. Kuyinqubo eshesha kakhulu futhi elula. Lokhu kusho ukuthi ungaya ekhaya ngosuku olufanayo ngemva kokuhlinzwa.
Cabanga ngeso lakho njengekhamera enhle. Ingxenye esebenza njengelensi yale khamera yi -cornea, engaphambili kweso. Ukukhanya kungena esweni ngale cornea. Ama-cornea abanye abantu abunjwe ngendlela ehlukile kancane. Ngenxa yalokho, ukukhanya akugxili ngqo ku-retina engaphakathi kweso. Njengalapho ikhamera 'iphuma ekugxileni', umbono uqala ukufiphala.
Ukuhlinzwa kwe-LASIK kusebenzisa umsebe we-laser omuhle kakhulu ukuze kulungiswe kabusha i-cornea yeso lakho. Lokhu kuvumela ukukhanya ukuthi kuwele ngqo ku-retina, okuholela ekuboneni okucacile, okungenakho ukufiphala.
Leli gama livela kuleyo ncazelo. I-LASIK isifinyezo segama elithi "Laser-Assisted In Situ Keratomileusis." Kalula nje, lisho "ukushintsha isimo se-cornea ngosizo lwe-laser."
Yiziphi izinhlobo zokukhubazeka kokubona ezingelapheka ngalolu hlinzeko?
Ukuhlinzwa kwe-LASIK kusebenza kakhulu ezinhlotsheni ezintathu eziyinhloko zokukhubazeka kokubona. Ake sibheke ukuthi ziyini.
| Ukukhubazeka kokubona | Kalula nje... |
|---|---|
| I-Myopia | Ungabona izinto eziseduze nawe (njengokufunda incwadi) ngokucacile, kodwa izinto ezikude (uphawu lwebhasi, i-TV) zibonakala zingacacile. |
| Ukubona Okuseduze (i-Hyperopia) | Ngisho noma ungabona izinto ezikude ngokucacile, izinto eziseduze (njengokubuka iphephandaba) azicacile kangako. |
| I-Astigmatism | Kulesi simo, ukuma kwe-cornea akujwayelekile, okwenza umbono ubonakale ungacacile futhi unwebekile uma ubheka noma yini eseduze noma ekude. Lesi simo sivame ukwenzeka kanye nokungaboni eduze. |
Ake sifunde nangokubona eduze okuhambisana nokuguga (i-Presbyopia)
Njengoba sikhula, ilensi engaphakathi kwamehlo ethu ilahlekelwa ukuguquguquka kwayo. Lokhu kwenza kube nzima ukubona eduze. Lokhu kubizwa ngokuthi i-Presbyopia . Nakuba i-LASIK ingenakuyelapha ngqo lesi simo, inqubo ebizwa ngokuthi 'i-monovision' ingasetshenziswa ukusiza iso elilodwa libone kude kanti elinye iso libone eduze. Lokhu kwenza ukubona eduze kube lula kakhulu.
Kwenzekani ngaphambi nangesikhathi sokuhlinzwa?
Uma unquma ukwenza ukuhlinzwa kwe-LASIK, udokotela wakho wamehlo uzokuhlola ngokucophelela ukuze abone ukuthi ungumuntu ofanele yini. Uzokwaziswa ukuthi ungasebenzisi noma yiziphi izithasiselo, izimonyo, noma amakha ngosuku olwandulela ukuhlinzwa, njengoba lokhu kungabangela izifo uma zingena emehlweni akho.
Nakhu okwenzekayo ngosuku lokuhlinzwa:
1. Amaconsi okubulala amehlo: Okokuqala, kufakwa amaconsi amehlo akho. Lokhu kubulala amehlo akho ukuze ungezwa ubuhlungu.
2. Ukugcina iso linganyakazi: Okulandelayo, kusetshenziswa ithuluzi elincane ukugcina iso lakho lisendaweni eyodwa futhi likuvimbele ukuthi ungacwayizi. Kuleli qophelo, ungase uzizwe sengathi othile ucindezela iso lakho. Ukubona kwakho kuzofiphala isikhashana.
3. Ukudala i-flap encane ye-cornea: Manje kuza ingxenye ebaluleke kakhulu. Udokotela ohlinzayo uzodala ngokucophelela i-flap encane kakhulu, njengekhasi encwadini, ongqimbeni oluphezulu lwe-cornea yakho. Ngemuva kwalokho, uzoyigoqa eceleni.
4. Ukwelashwa nge-laser: Manje uzocelwa ukuthi ubheke ukukhanya. Njengoba ubheka, i-laser ishintsha i-cornea yakho esikhathini semizuzwana embalwa. Ungase uzwe umsindo 'wokukhahlela' phakathi nalesi sikhathi. Abanye abantu bangase baqaphele nomuzwa wokushisa. Kodwa-ke, akuyona into eshisayo, kumane kuyimpendulo yamakhemikhali eyenzeka lapho i-laser ishintsha i-cornea.
5. Ukunamathisela kabusha i-flap: Uma ukwelashwa nge-laser sekuqediwe, i-cornea flap esusiwe kulolo hlangothi inamathiselwa kabusha endaweni yayo yokuqala. Izoqala ukunamathela ngokushesha. Akukho kuthunga okuzofakwa.
Lonke lolu hlelo luthatha imizuzu engaphansi kwengu-30.
Kwenzekani ngemva kokuhlinzwa?
Uma ukuhlinzwa sekuphelile, umbono wakho uzoba sobala kancane. Kodwa kungase kuzwakale sengathi ubheka ngengilazi engcolile. Ungaya ekhaya ngalolo suku, kodwa kuzodingeka omunye umuntu ashayele imoto.
Udokotela wakho uzokunikeza okulandelayo:
- Isivikelo samehlo: Lesi kufanele sigqokwe ukuze uvikele amehlo akho futhi sikuvimbele ukuthi ungawathinti ngephutha.
- Izinhlobo eziningana zamaconsi amehlo: Kungase kudingeke usebenzise izinhlobo eziningana zamaconsi amehlo ukwelapha amehlo omile, ukuvimbela izifo, nokunciphisa ukuvuvukala.
Kujwayelekile ukuzwa ukungakhululeki, ukulunywa, amehlo anamanzi, kanye nokuzwela ukukhanya esontweni lokuqala. Kungakhathaliseki ukuthi kuyalunywa kangakanani, ungawahlikihli amehlo akho, njengoba lokhu kungalimaza i-cornea.
Yiziphi izinzuzo nemiphumela emibi ye-LASIK?
Njenganoma yiluphi ukwelashwa kwezokwelapha, i-LASIK ingaba nezinzuzo kanye nemiphumela emibi emincane.
| Izinzuzo | Imiphumela Engase Ibe Khona |
|---|---|
| Ungakuqeda ngokuphelele noma kakhulu ukuthembela kwakho ezibukweni noma kuma-contact lens. | Amehlo Omile - Lona umphumela ovame kakhulu. Ngokuvamile uphela ngokuphelele zingakapheli izinyanga ezingu-6-12. |
| Kukhona izinga lempumelelo eliphezulu kakhulu (ngaphezu kuka-96%). | Ukubona ukukhanya noma amaringi (i-Glare/Halos) eduze kwezibani ebusuku. |
| Imiphumela ihlala njalo (kodwa izinguquko zemvelo emehlweni zingase zenzeke njengoba sikhula). | Ukuzwela ukukhanya. |
| Kuthatha isikhathi esifushane kakhulu ukuphulukiswa. | Amabala amancane abomvu kumhlophe weso (lawa ayanyamalala ngokwawo). |
Iningi lale miphumela emibi liyiyesikhashana futhi liyanyamalala zingakapheli izinyanga ezimbalwa. Ingozi yezinkinga ingaphansi kuka-1%.
Ngingakwazi yini ukuhlinzwa kwe-LASIK?
I-LASIK ayilungele wonke umuntu. Kunezici eziningana ezizonquma ukuthi uyayifanelekela yini.
- Ubudala: Kumelwe ube neminyaka engaphezu kwengu-18 ubudala. Ezimweni eziningi, kungcono ukulinda uze ube neminyaka engu-20, njengoba umbono usuzinzile ngaleso sikhathi.
- Umbono ozinzile: Imithi yakho kadokotela akufanele ishintshe kakhulu, okungenani ngonyaka odlule.
- Ubukhulu be-cornea: I-cornea kumele ibe nkulu ngokwanele.
- Izimo zempilo: Lokhu kuhlinzwa akukhuthazwa kubantu abanezimo ezifana nesifo samehlo esomile kakhulu, i-keratoconus (ubuthakathaka be-cornea), i-cataracts, i-glaucoma, kanye nesifo sikashukela esingalawuleki.
Ngakho-ke, uma unesithakazelo ku-LASIK, into yokuqala okufanele uyenze ukuvakashela udokotela ohlinza amehlo onolwazi ukuze ahlolwe amehlo ngokuphelele. Uzohlola amehlo akho futhi achaze ukuthi asebenza kangakanani kuwe, ukuthi yiziphi izingozi, nokuthi yiziphi izinketho zakho ezingcono kakhulu.
Umlayezo Wokuya Nawe Ekhaya
- I-LASIK iyindlela yokuhlinzwa ephephile kakhulu futhi ephumelelayo elungisa izinkinga zokubona (ukubona kude/ukubona eduze, i-astigmatism) kusetshenziswa ubuchwepheshe be-laser.
- Ngemva kwalokhu kuhlinzwa, cishe ungasusa ngokuphelele izibuko noma ama-contact lens.
- Akukho ubuhlungu ngesikhathi sokuhlinzwa, futhi isikhathi sokululama sifushane kakhulu.
- Akuwona wonke umuntu ongaba ne-LASIK. Udokotela wakho wamehlo uzonquma ukuthi ungumuntu ofanele yini kule nqubo ngemva kokuhlolwa okuphelele.
- Imiphumela emibi yesikhashana, njengamehlo omile, ingase ivele ngemva kokuhlinzwa, kodwa izinkinga ezinkulu azivamile.
- Uma nawe unesithakazelo ku-LASIK, ungesabi ukuhlangana nodokotela ofanelekayo nixoxe ngakho.
