Ingabe uhlala ugqoka izibuko? Noma usebenzisa ama-contact lens? Ngezinye izikhathi ufisa sengathi ungakhululeka kuzo futhi ubone umhlaba ngokucacile ngaphandle kosizo, akunjalo? Namuhla sikhuluma ngendlela yokuhlinzwa nge-laser engakusiza ukuthi ufeze iphupho elinjalo. Lokhu kubizwa ngokuthi ukuhlinzwa kwe-PRK. Ake sibheke lokhu kalula.
Kuyini i-PRK?
Kalula nje, i-Photorefractive Keratectomy, noma i-PRK, inqubo yokuhlinzwa nge-laser yokulungisa umbono wakho. Kuhilela ukusebenzisa i-laser ukushintsha kancane ukuma kwengqimba ecacile nevikelayo ngaphambili kweso lakho, i-cornea. Cabanga nge-cornea njengelensi yekhamera. Lapho ukukhanya kungena esweni, kuyagoba futhi kugxile ku-retina. Ngakho-ke, ngokushintsha kancane ukuma kwe-cornea, indlela ukukhanya okugxile ngayo iyashintsha, futhi ungabona kahle.
Eqinisweni, le ndlela ebizwa ngokuthi i-PRK yindlela eyafika ngaphambi kokuhlinzwa kwe-LASIK abantu abaningi abakhuluma ngayo namuhla. Kodwa indlela ye-PRK iseyindlela yokwelapha ewusizo kakhulu futhi ethandwayo namuhla. Ikakhulukazi kwezinye izimo lapho i-LASIK ingenakwenzeka, i-PRK iyisisombululo esingcono kakhulu.
Yiziphi izinhlobo zezinkinga zokubona ezingelashwa ngokuhlinzwa kwe-PRK?
Ukuhlinzwa kwe-PRK kungalungisa izinkinga eziningana ezinkulu emehlweni ethu, ezibangelwa ukukhanya okungagxili kahle ku-retina (iphutha lokuqhekeka). Ake sibheke ukuthi ziyini.
| Iphutha Lokubheka Okubonakalayo | Kuchazwe kalula |
|---|---|
| Ukubona eduze / i-Myopia | Izinto eziseduze zibonakala zicacile, kodwa izinto ezikude zibonakala zingacacile. |
| Ukubona kude / i-Hypopia | Ukubona izinto ezikude ngokucacile, kodwa ukubona izinto eziseduze (isib., lapho ufunda incwadi) njengokungacacile. |
| I-Astigmatism | Ngenxa yokuthi ukuma kwe-cornea akusiyindilinga ngokuphelele, umbono oseduze nakude ufiphele futhi uphambene. |
| I-Presbyopia (ukubona eduze) njengoba ukhula | Ngemva kweminyaka engu-40, ukuguquguquka kwelensi yeso kuyancipha, okubangela ubunzima bokubona eduze. |
Uzilungiselela kanjani ngaphambi kokuhlinzwa?
Kunezinto eziningana udokotela wakho wamehlo angakusiza ngazo ngaphambi kokuhlinzwa kwe-PRK.
- Ukuhlolwa kwamehlo okuphelele: Lokhu kuzohlola umbono wakho kanye nempilo yakho yonke yamehlo. Kuzohlola nanoma yiziphi ezinye izimo zezokwelapha ezingakuvimbela ukuthi ube ne-PRK.
- Ukulinganiswa kobuso be-cornea: Kusetshenziswa imishini ekhethekile ukudala ``imephu`` ye-cornea yakho. Lezi zilinganiso zibaluleke kakhulu ekwelashweni nge-laser.
Into ebaluleke kakhulu ukuba nokulindela okungokoqobo ngemiphumela. Lokhu akuwona umlingo. Kubaluleke kakhulu ukukhuluma ngokukhululekile nodokotela wakho nokuqonda okucacile ngalokho okufanele ukulindele ngemva kokuhlinzwa.
Kwenzekani ngesikhathi sokuhlinzwa?
I-PRK inqubo yokulaliswa esibhedlela ngaphandle kwesibhedlela. Lokho kusho ukuthi ungaya ekhaya ngalolo suku. Yonke inqubo ithatha imizuzu emi-5 kuya kweyi-15 kuphela. Uvukile phakathi nalesi sikhathi. Kodwa ungakhathazeki, ngeke uzwe ubuhlungu . Udokotela uzokufaka amaconsi aqeda izinhlungu emehlweni akho.
1. Ngemva kokuba amehlo akho esephelelwe amandla, udokotela wakho uzosusa ungqimba oluncane lwezicubu phezu kwe-cornea yakho, olubizwa ngokuthi i-epithelium. Lokhu kuzophinde kukhule ezinsukwini ezimbalwa.
2. Ngemuva kwalokho, ucelwa ukuthi ubheke ukukhanya okugxilile okuvela emshinini we-laser. Ngesikhathi ubheka, i-laser ingaguqula i-cornea ibe yinhle kakhulu.
3. I-laser iyavulwa ngenkathi ubheka okuqondiwe. Awukwazi ukubona umsebe we-laser, kodwa ungezwa umsindo omncane "ohlabayo" ovela emshinini. Le laser isusa izicubu ze-cornea ngokucophelela, ngaphandle kokuzifudumeza.
4. Uma ukwelashwa nge-laser sekuqediwe, udokotela uzofaka amaconsi ambalwa emithi esweni bese efaka i-'bandage contact lens' ekhethekile ukuze avikeleke. Lokhu kuzovikela iso kuze kube yilapho ungqimba lwezicubu olususiwe lukhula futhi.
Kufanele uzinakekele kanjani ngemva kokuhlinzwa?
Ungaya ekhaya ngemva kokuhlinzwa, kodwa udinga ukunakekela lezi zinto.
- Phumula kahle:Phumula ngokwanele ezinsukwini ezimbalwa zokuqala. Gwema umsebenzi onzima womzimba. Kungcono ukugwema ukuya emsebenzini noma esikoleni izinsuku ezimbalwa kuze kube yilapho udokotela wakho ekuyala.
- Gwema ukushayela: Ungashayeli okungenani izinsuku ezimbalwa ngemva kokuhlinzwa.
- Sebenzisa umuthi njengoba nje udokotela wakho ekuyalele. Lokhu kubalulekile ukuze uthole imiphumela emihle kakhulu.
- Gqoka izibuko zelanga: Gqoka izibuko zelanga noma nini lapho uphuma emini, kuze kube yilapho udokotela wakho ekuyala. Lokhu kuzovimbela umonakalo kanye nezibazi ku-cornea ezivela emisebeni ye-ultraviolet (UV).
I-PRK noma i-LASIK, yikuphi okungcono?
Ukuhlinzwa kwe-LASIK kuvame ukuthandwa ngoba kuhilela isikhathi esincane sokululama kanye nobuhlungu obuncane. Kodwa-ke, kwabanye abantu, i-PRK iyindlela engcono kune-LASIK. Ake sibheke ukuthi kungani.
| I-PRK ifaneleka kakhulu kulezi zimo. | I-LASIK ifaneleka kakhulu kulezi zimo |
|---|---|
| Uma unenkinga yamehlo omile . | Uma ufuna ukululama ngokushesha bese ubuyela emsebenzini. |
| Uma i-cornea yakho incane , i-PRK iphephile ngoba ayinqamuli ngisho nengxenye ye-cornea njengase-LASIK. | Uma ufuna ukunciphisa ubuhlungu nokungakhululeki ngemva kokuhlinzwa. |
| Uma uphila impilo ematasa kakhulu, njengokudlala imidlalo (kunengozi yokuthi i-flap edalwe ngesikhathi se-LASIK iphume engozini enkulu). | Uma ubukhulu nesimo se-cornea yakho kufanelekile kwi-LASIK. |
Khumbula into eyodwa, akukho ukuhlinzwa okukodwa okungcono kakhulu kuwo wonke umuntu. Kuye ngezici ezifana nesimo samehlo akho nendlela yakho yokuphila,Udokotela wakho wamehlo kuphela ongakusiza ukhethe indlela engcono kakhulu kuwe.
Kuthatha isikhathi esingakanani ukuphulukiswa?
Ukululama ngemva kokuhlinzwa kwe-PRK kuyinqubo eyenzeka kancane kancane.
Izinsuku zokuqala ezi-3
Cishe ihora ngemva kokuhlinzwa, ungase uzizwe ubuhlungu kanye nokungakhululeki njengoba ukuba ndikindiki kuphela. Ukudabuka kwamehlo, ukuzwela ukukhanya, umuzwa wesihlabathi esweni, kanye nokungaboni kahle kuvamile. Lokhu kungalawulwa ngamaphilisi obuhlungu anikezwa udokotela wakho.
Izinsuku 4 no-5
Okwamanje, ungqimba lwangaphandle lwe-cornea (i-'epithelium') seluphinde lwavuselelwa ngokuphelele. Ukungakhululeki sekunciphile kakhulu, futhi umbono wakho uqala ukucaca kancane. Udokotela uzosusa 'ilensi yakho yokuxhumana yebhandeji' kulezi zinsuku.
Ngemva kosuku lwesi-5
Umbono wakho uzocaca kancane kancane emasontweni ambalwa azayo. Kungathatha inyanga noma ngaphezulu ukuthi umbono wakho ululame ngokugcwele futhi uzinze. Abanye abantu bangase babe nezinguquko ezincane embonweni wabo kuze kube yizinyanga ezi-3-6.
Kufanele ukhulume nini nodokotela?
Uma uhlangabezana nezimpawu ezilandelayo, shayela udokotela wakho ngokushesha.
- Ukulahlekelwa umbono ngokuzumayo noma ukulahlekelwa umbono okukhulu.
- Ubuhlungu bamehlo buyanda usuku nosuku, abubekezeleleki ngisho nangemithi.
- Izimpawu zokutheleleka zihlanganisa ukuvuvukala kwamehlo, ukudabuka ngokweqile, kanye nokubomvu.
Umlayezo Wokuya Nawe Ekhaya
- I-PRK inqubo yokuhlinzwa nge-laser ephephile futhi ephumelelayo enganciphisa ukuncika ezibukweni noma kuma-contact lens.
- I-PRK iyindlela enhle kakhulu kulabo abangakwazi ukuhlinzwa kwe-LASIK, ikakhulukazi labo abane-cornea encane noma labo abanezinkinga zamehlo omile.
- Isikhathi sokululama ngemva kokuhlinzwa kwe-PRK side kunese-LASIK, kodwa imiphumela yokugcina icishe ifane kokubili.
- Ukuze uthole imiphumela emihle kakhulu, kubalulekile ukulandela imiyalelo kadokotela wakho kanye nemithi yakhe ngaso sonke isikhathi ngemva kokuhlinzwa.
- Ngaphambi kokwenza noma yiziphi izinqumo, xoxa nodokotela wakho ngalokho okulindelwe kanye nanoma yimiphi imibuzo ongase ube nayo ukuze uthole ukuqonda okucacile.
