Ngaba udiniwe kukunxiba iiglasi nokutshintsha iilensi zoqhagamshelwano qho kusasa nangokuhlwa? Ngaba udiniwe kukuvuka kusasa ubone ihlabathi lifiphele? Ngoko ke umele ukuba ulivile igama elithi 'LASIK'. Abantu abaninzi bacinga ukuba liqhinga lomlingo lokucoca umbono wabo. Ngoko ke, namhlanje siza kuthetha ngolu tyando lwe-LASIK, nokuba luyinyani okanye alunjalo, izibonelelo kunye neengxaki zalo, nokuba lufanelekile na kuwe, ngokulula nje, ngokungathi sithetha nomhlobo.
Ngamafutshane, yintoni iLASIK?
I-LASIK lutyando olusebenzisa ubuchwepheshe be-laser obuphambili ukulungisa umbono wakho. Yinkqubo ekhawulezayo nelula kakhulu. Oku kuthetha ukuba ungagoduka ngosuku olunye emva kotyando.
Cinga ngeliso lakho njengekhamera elungileyo. Inxalenye esebenza njengelensi yale khamera yi -cornea, ephambi kweliso. Ukukhanya kungena kweliso ngale cornea. I-cornea zabanye abantu zenziwe ngendlela eyahlukileyo kancinci. Ngenxa yoko, ukukhanya akujolisi ngqo kwi-retina engaphakathi kweliso. Njengaxa ikhamera 'ingajolisi', umbono uqala ukuba mfiliba.
Utyando lwe-LASIK lusebenzisa umqadi welaser ocolekileyo kakhulu ukuze lutshintshe i-cornea yeliso lakho. Oku kuvumela ukukhanya ukuba kungene ngqo kwi-retina, nto leyo ekhokelela ekuboneni okucacileyo, okungenamsoco.
Eli gama livela kuloo ntsingiselo. I-LASIK sisifinyezo segama elithi "Laser-Assisted In Situ Keratomileusis." Ngamafutshane, lithetha "ukutshintsha imo ye-cornea ngoncedo lwe-laser."
Zeziphi iintlobo zokuphazamiseka kokubona ezinokunyangwa ngolu tyando?
Utyando lwe-LASIK lusebenza kakhulu kwiintlobo ezintathu eziphambili zokuphazamiseka kokubona. Makhe sijonge ukuba ziyintoni na.
| Ukukhubazeka kokubona | Kalula nje... |
|---|---|
| I-Myopia | Ungazibona ngokucacileyo izinto ezikufutshane nawe (njengokufunda incwadi), kodwa izinto ezikude (uphawu lwebhasi, iTV) zibonakala zingacacanga. |
| Ukubona kufutshane (i-Hyperopia) | Nangona ungazibona izinto ezikude ngokucacileyo, izinto ezikufutshane (njengokujonga iphephandaba) azicacanga kangako. |
| I-Astigmatism | Kule meko, imilo ye-cornea ayihambelani kakuhle, nto leyo ebangela ukuba umbono ubonakale ungacacanga kwaye unwebekile xa ujonge nantoni na ekufutshane okanye ekude. Le meko idla ngokudibana nokungaboni kakuhle. |
Masifunde nangokubona izinto ezikufutshane okuza nokwaluphala (iPresbyopia)
Njengoko sikhula, ilensi engaphakathi kwamehlo ethu ilahlekelwa bububhetyebhetye bayo. Oku kwenza kube nzima ukubona kufutshane. Oku kubizwa ngokuba yiPresbyopia . Nangona i-LASIK ingenakuyinyanga ngokuthe ngqo le meko, indlela ebizwa ngokuba yi-'monovision' ingasetyenziselwa ukunceda elinye iliso libone kude kwaye elinye iliso libone kufutshane. Oku kwenza ukubona kufutshane kube lula kakhulu.
Kwenzeka ntoni ngaphambi nangexesha lotyando?
Ukuba ugqiba ekubeni wenze utyando lwe-LASIK, ugqirha wakho wamehlo uza kukuxilonga ngononophelo ukuze abone ukuba ungumntu ofanelekileyo na. Uya kucetyiswa ukuba ungasebenzisi naziphi na izinto zokugcoba, izimonyo, okanye iziqholo ngosuku olungaphambi kotyando, kuba ezi zinto zinokubangela usulelo ukuba zingena emehlweni akho.
Nantsi into eyenzekayo ngomhla wotyando:
1. Amathontsi abangela ukuba amehlo angasebenzi kakuhle: Okokuqala, kufakwa amathontsi emehlweni akho. Oku kugcina amehlo akho engasebenzi kakuhle ukuze ungabi nantlungu.
2. Ukugcina iliso linganyakazi: Okulandelayo, kusetyenziswa isixhobo esincinci ukugcina iliso lakho likwindawo enye kwaye sikuthintele ekuqhwanyeleni. Ngeli xesha, ungaziva ngathi kukho umntu ocinezela iliso lakho. Ukubona kwakho kuya kuba luzizi okwethutyana.
3. Ukudala i-flap encinci ye-cornea: Ngoku kuza eyona nxalenye ibalulekileyo. Ugqirha uza kwenza i-flap encinci kakhulu, njengephepha elisencwadini, kumaleko ophezulu we-cornea yakho. Emva koko, uza kuyisonga ecaleni.
4. Unyango lweLaser: Ngoku uza kucelwa ukuba ujonge ukukhanya. Njengoko ujonge, ilaser itshintsha i-cornea yakho kangangemizuzwana embalwa. Usenokuva isandi 'esithintithayo' ngeli xesha. Abanye abantu banokubona nemvakalelo yokutsha. Nangona kunjalo, asikokutsha, yimpendulo nje yeekhemikhali eyenzeka xa ilaser itshintsha i-cornea.
5. Ukufakelwa kwakhona kwe-flap: Nje ukuba unyango lwe-laser lugqityiwe, i-cornea flap eyayisusiwe kwelo cala iphinda inamathele kwindawo yayo yokuqala. Iya kuqala ukunamathela ngoko nangoko. Akukho kuthunga kuya kufakwa.
Lonke eli xesha lithatha ngaphantsi kwemizuzu engama-30.
Kwenzeka ntoni emva kotyando?
Xa utyando luphelile, umbono wakho uya kuba sobala kancinci. Kodwa kusenokuvakala ngathi ujonge ngeglasi engcolileyo. Ungagoduka ngaloo mini inye, kodwa kuya kufuneka omnye umntu aqhube imoto.
Ugqirha wakho uza kukunika oku kulandelayo:
- Isikhuselo samehlo: Esi sigqubuthelo samehlo kufuneka sinxitywe ukuze sikhusele amehlo akho kwaye sikuthintele ekubeni ungawachukumisi ngengozi.
- Iintlobo ezahlukeneyo zamathontsi eliso: Kusenokufuneka usebenzise iintlobo ezahlukeneyo zamathontsi eliso ukunyanga amehlo omileyo, ukuthintela usulelo, kunye nokunciphisa ukudumba.
Kuqhelekile ukuba ube nokungakhululeki, ukurhawuzelelwa, amehlo anamanzi, kunye nokuziva ukhululekile ekukhanyeni kwiveki yokuqala. Nokuba kurhawuzelelwa kangakanani na, musa ukuhlikihla amehlo akho, kuba oku kungonakalisa i-cornea.
Ziziphi iingenelo kunye nemiphumo emibi yeLASIK?
Njengalo naluphi na unyango lwezonyango, i-LASIK inokuba neenzuzo kunye nemiphumo emibi emincinci.
| Iingenelo | Iziphumo Ezingalindelekanga Ezinokwenzeka |
|---|---|
| Ungayiphelisa ngokupheleleyo okanye kakhulu into yokuba uxhomekeke kwiiglasi okanye kwiilensi zonxibelelwano. | Amehlo Omileyo - Le yeyona miphumo ixhaphakileyo. Idla ngokuphela ngokupheleleyo kwiinyanga ezi-6-12. |
| Kukho izinga eliphezulu kakhulu lempumelelo (ngaphezulu kwama-96%). | Ukubona ukukhanya okanye izangqa (iGlare/Halos) zijikeleze izibane ebusuku. |
| Iziphumo zihlala zihleli (kodwa utshintsho lwendalo emehlweni lunokwenzeka njengoko sikhula). | Uvelwano ekukhanyeni. |
| Kuthatha ixesha elifutshane kakhulu ukuphiliswa. | Amabala amancinci abomvu kumhlophe weliso (la ayanyamalala ngokwawo). |
Uninzi lwezi ziphumo bezingalindelekanga zezokwexeshana kwaye ziyaphela kwiinyanga ezimbalwa. Umngcipheko weengxaki ungaphantsi kwe-1%.
Ndingatyandwa i-LASIK?
I-LASIK ayifanele wonke umntu. Zininzi izinto eziya kuqinisekisa ukuba uyayifanelekela na.
- Ubudala: Kufuneka ube ungaphezulu kweminyaka eli-18 ubudala. Kwiimeko ezininzi, kungcono ukulinda ude ube neminyaka engama-20 ubudala, njengoko umbono wakho uzinzile ngelo xesha.
- Umbono ozinzileyo: Unyango lwakho belungafanelanga ukuba lutshintshe kakhulu, ubuncinane kunyaka ophelileyo.
- Ubukhulu be-cornea: I-cornea kufuneka ibe nkulu ngokwaneleyo.
- Iimeko zempilo: Olu tyando alukhuthazwa kubantu abaneemeko ezifana nesifo samehlo esomileyo kakhulu, i-keratoconus (ubuthathaka be-cornea), i-cataracts, i-glaucoma, kunye nesifo seswekile esingalawulekiyo.
Ngoko ke, ukuba unomdla kwi-LASIK, into yokuqala omawuyenze kukutyelela ugqirha wamehlo onamava ukuze akuhlole ngokupheleleyo. Uza kuhlola amehlo akho aze akuchazele ukuba isebenza kangakanani kuwe, zithini iingozi, kunye nezona ndlela zilungileyo onokuzisebenzisa.
Umyalezo Wokuya Ekhaya
- I-LASIK lutyando olukhuselekileyo noluphumeleleyo olulungisa iziphene zokubona (ukubona kude/ukubona kufuphi, i-astigmatism) kusetyenziswa ubuchwepheshe be-laser.
- Emva kolu tyando, ungasusa phantse ngokupheleleyo iiglasi okanye iilensi zoqhagamshelwano.
- Akukho ntlungu ngexesha lotyando, kwaye ixesha lokuchacha lifutshane kakhulu.
- Asinguye wonke umntu onokuba ne-LASIK. Ugqirha wakho wamehlo uza kuqinisekisa ukuba ungumntu ofanelekileyo na kule nkqubo emva kokuhlolwa ngokucokisekileyo.
- Iziphumo ebezingalindelekanga zexeshana, ezinje ngamehlo omileyo, zinokwenzeka emva kotyando, kodwa iingxaki ezinkulu azifumaneki rhoqo.
- Ukuba nawe unomdla kwi-LASIK, ungoyiki ukudibana nogqirha ofanelekileyo nize nithethe ngayo.
