Ingabe uzithola uthatha izibuko zakho njalo ekuseni? Noma ukhathele ukungakhululeki kokugqoka ama-contact lens usuku lonke? Uma kunjalo, kungenzeka ukuthi ubucabanga ngendlela yokubona umhlaba ngokucacile ngaphandle kwezibuko. Namuhla, sikhuluma ngesisombululo esingaba khona. Lokho ukuhlinzwa kokulungisa umbono, noma lokho esikubiza ngokuthi "Ukuhlinzwa Kokulungisa Umbono."
Kalula nje, kuyini lokhu kuhlinzwa kokulungisa umbono?
Lokhu kulula kakhulu. Amehlo ethu abona lapho ukukhanya kungena esweni futhi agxile endaweni ebizwa ngokuthi i-retina. Kodwa-ke, amehlo abanye abantu awagxilile kahle ngenxa yomehluko omncane esimweni samehlo abo. Lokhu sikubiza ngokuthi iphutha lokubona. Yingakho singakwazi ukubona kude noma eduze.
Ngakho-ke, lokhu kuhlinzwa kuhilela ukwenza ushintsho oluncane ezingxenyeni ezimbili zeso lethu ukuze ukukhanya okungena esweni kugxile kahle.
1. I-Cornea: Lena yingxenye ecacile, efana nengilazi, eyindilinga yeso lethu ngaphambili. Cishe u-75% wokukhanya okungena esweni ugobile, noma uphendukezelwe, lapha.
2. Ilensi: Ngemva kwe-cornea, ukukhanya kudlula kule lensi. Yilokhu okugxila ukukhanya kahle kakhulu futhi kukuthumele ngqo ku-retina.
Ngakho-ke, lokhu kuhlinzwa kusebenzisa i-laser ukushintsha kancane ukuma kwe-cornea, noma kufakwa ilensi yokwenziwa ngaphakathi kweso. Noma ngabe wenzani, umphumela wokugcina uba ukuthi ukukhanya kugxile kahle futhi uthola umbono ocacile.
Yiziphi izindlela ezahlukene zalokhu kuhlinzwa?
Kunezindlela ezimbili eziyinhloko. Futhi akuzona zonke ezizofanelana nawe. Lokho kuncike kudokotela wakho wamehlo ukuthi anqume.
| Uhlobo lokuhlinzwa | Kwenzekani nje? |
|---|---|
| Ukuhlinzwa nge-laser | Lokhu kuhilela ukusebenzisa umsebe we-laser okhethekile ukushintsha ngokungabonakali isimo sobuso be-cornea. Lokhu kushintsha indlela ukukhanya okujika ngayo, kuthuthukise umbono. |
| Ukuhlinzwa Kokubekwa Kwelensi | Lokhu kuhilela ukufaka ilensi yokwenziwa eyenziwe ngokwezifiso ukuze ilingane neso lakho. Ngezinye izikhathi ilensi yakho yemvelo iyasuswa bese ifakwa, kanti ngezinye izikhathi ilensi entsha ifakwa ngenkathi ilensi yemvelo isesendaweni yayo. |
Ezinye zezinqubo zokuhlinzwa ezisetshenziswa kakhulu:
- I-LASIK (I-Laser-Assisted In Situ Keratomileusis): Lena yindlela ethandwa kakhulu eyenziwa abantu abaningi emhlabeni.
- I-PRK (Photorefractive Keratectomy): Ifana ne-LASIK, kodwa ngenqubo ehluke kancane.
- UKUMOMOTHEKA (Ukukhishwa Kwe-Lenticule Encane): Lokhu futhi ubuchwepheshe obusha be-laser.
- Ukubekwa kwe-Phakic IOL: Yilapho kufakwa khona ilensi yokwenziwa ngaphandle kokususa ilensi yemvelo.
- Ukushintshana Kwelensi Ebonakalayo: Kulokhu, ilensi yemvelo iyasuswa bese kufakwa ilensi yokwenziwa. Lokhu kufana kancane nokuhlinzwa kwe-cataract.
Iyiphi indlela engcono kakhulu kimi?
Lona umbuzo obaluleke kakhulu. Ayikho "indlela engcono kakhulu." Okusebenza kahle kuwe kungase kungasebenzi komunye umuntu. Udokotela wakho wamehlo ungumuntu ongcono kakhulu wokwenza lesi sinqumo. Uzocabangela okulandelayo:
- Inkinga yakho yokubona: Kungakhathaliseki ukuthi unesifo sokubona eduze (Myopia), isifo sokubona kude (Hyperopia), noma i-astigmatism. Abanye abantu bangase babe nenhlanganisela yalezi zinto.
- Ubukhulu besici: Indlela efanele izohluka kuye ngokuthi ukukhubazeka kwakho kokubona kungakanani.
- Impilo iyonke yamehlo akho: Uma unezinye izimo zamehlo, njengesifo samehlo esomile noma i-glaucoma, ezinye izinqubo zokuhlinzwa azikhuthazwa.
Ngakho-ke, ungenzi izinqumo ngokusekelwe kulokho okubonayo ku-inthanethi noma kulokho umngane athi bakwenzile. Khuluma nodokotela wakho wamehlo bese ukhetha indlela engcono kakhulu kuwe ngokusekelwe eselulekweni sakhe.
Kufanele ngilungiselele kanjani ngaphambi kokuhlinzwa?
Udokotela wakho uzokwenza izivivinyo eziningana ngaphambi kokuhlinzwa.
- Ukuhlolwa kokubona: Iphutha lakho lokubona kufanele lilinganiswe ngokunembile. Udokotela wakho kufanele futhi ahlolwe ukuze kubonakale ukuthi "uzinzile." Lokhu kusho ukuthi umtholampilo wakho akufanele ushintshe kakhulu ngonyaka odlule noma ngaphezulu.
- Ukuhlolwa kwempilo yamehlo: Ukuhlolwa kwezinye izimo zezokwelapha.
- Ukumapha Kobuso Beso: Umshini okhethekile wokuskena udala imephu enemininingwane eminingi ye-cornea yakho. Lokhu kubaluleke kakhulu ekuhleleni ukuhlinzwa.
Ngaphezu kwalokho, udokotela uzokutshela:
- Ingabe kufanele uqhubeke nokuphuza imithi yakho, noma kufanele uyiyeke ngaphambi kokuhlinzwa?
- Ingabe bazokunika amaconsi amehlo afana nama-antibiotic ukuze uwafake emehlweni akho ngaphambi kokuhlinzwa, nokuthi uwasebenzisa kanjani?
- Ungase ucelwe ukuthi uzile ukudla amahora ambalwa ngaphambi kokuhlinzwa.
Kwenzekani ngesikhathi sokuhlinzwa?
Akukho okufanele ukhathazeke ngakho. Lena inqubo yokulaliswa esibhedlela . Lokhu kusho ukuthi akudingeki uhlale esibhedlela, futhi ungaya ekhaya ngalolo suku.
Okokuqala, bafaka amaconsi amehlo aqeda amandla emehlweni akho, ukuze ungezwa ubuhlungu. Bese besebenzisa ithuluzi elincane ukubamba amehlo akho avuleke.
Okwenzekayo ngokulandelayo kuzoncika ohlotsheni lokuhlinzwa olwenzayo. Enqubweni efana ne-LASIK, kwakheka i-flap encane kakhulu ku-cornea, bese isuswa iye kolunye uhlangothi bese kufakwa umsebe we-laser kuyo. Uma inqubo isiqediwe, i-flap iyabuyiselwa endaweni yayo bese ivalwa. Yonke inqubo ithatha isikhathi esifushane kakhulu, cishe imizuzu eyi-15-30.
Yiziphi izinzuzo nezingozi?
Njenganoma iyiphi inqubo yezokwelapha, lena inezinzuzo kanye nezingozi ezincane.
Izinzuzo eziyinhloko:
- Izinga lempumelelo eliphezulu kakhulu: Abantu abangaphezu kuka-95% abahlinzwa nge-laser bajabule kakhulu ngemiphumela. Abantu abangaphezu kuka-90% banokubona okuhle ngaphandle kwezibuko.
- Izinga lempilo elithuthukisiwe: Ungaqeda ukuthembela kwakho ezibukweni nakuma-contact lens. Lena inkululeko enkulu kumuntu odlala imidlalo noma obhukudayo.
Izinto okufanele uzicabangele (izingozi):
- Ungadinga izibuko: Ngezinye izikhathi umbono wakho ungase ungabi ngoqondile ngokuphelele. Kodwa noma kunjalo, uzoba nombono ongcono kakhulu kunangaphambili. Ungadinga kuphela isibuko esinamandla amancane ezimweni ezithile, njengokushayela ebusuku.
- Imiphumela emibi: Amehlo omile kanye nokuzwela ukukhanya kungase kwenzeke emasontweni ambalwa okuqala ngemva kokuhlinzwa. Lokhu kuvame ukuphela zingakapheli izinsuku ezimbalwa.
- I-Presbyopia: Lokhu kuhlinzwa akukwazi ukuvimba ukubona eduze okwenzeka ngemva kweminyaka engu-40. Kunezixazululo ezahlukene zalokho.
- Izinkinga: Akuvamile kakhulu ukuthi kube nezinkinga ezifana nokutheleleka. Yingakho kubalulekile ukwenza lokhu ngudokotela oqeqeshiwe nonolwazi endaweni enezikhungo ezinhle .
Ungawavikela kanjani amehlo akho ngemva kokuhlinzwa?
Izinsuku ezimbalwa zokuqala ngemva kokuhlinzwa zibaluleke kakhulu.
- Ungawahlikihli amehlo akho: Ngisho noma amehlo akho ezwa eluma noma omile, ungawahlikihli. Sebenzisa amaconsi amehlo njengoba nje udokotela wakho ekuyalele.
- Zivikele elangeni: Uma uphuma, qiniseka ukuthi ugqoka izibuko zelanga ezivikelwe kahle yi-UV.
- Gwema ukuthola amanzi noma uthuli emehlweni: Qaphela ukuthi ungatholi amanzi emehlweni akho lapho ugeza noma ugeza ubuso bakho isonto elilodwa noma amabili. Gwema amachibi okubhukuda.
- Landela iseluleko sezokwelapha: Buza udokotela wakho ukuthi kufanele ugweme isikhathi esingakanani ukuphakamisa izinto ezisindayo nokuzivocavoca okunzima.
Umlayezo Wokuya Nawe Ekhaya
- Ukuhlinzwa Kokulungisa Umbono kuyindlela ephumelela kakhulu yokunciphisa noma yokuqeda ngokuphelele ukuthembela kwakho ezibukweni noma kuma-contact lens.
- Kunezindlela ezahlukahlukene ezifana ne-LASIK, i-PRK, kanye ne-SMILE, futhi kufanele ukhethe indlela ekufanele kakhulu ngemva kokuxoxa ngayo nodokotela wakho wamehlo.
- Nakuba lokhu kuyindlela yokuhlinzwa ephephile kakhulu, yesikhashana, kunezingozi ezincane nemiphumela emibi.
- Ukuze uthole imiphumela emihle kakhulu ngemva kokuhlinzwa, kubaluleke kakhulu ukulandela imiyalelo kadokotela ngqo, ikakhulukazi imiyalelo ephathelene nokuvikelwa kwamehlo.
- Uma ubona izinguquko ezisheshayo embonweni, ubuhlungu obukhulu, noma izimpawu zokutheleleka, yazisa udokotela wakho ngokushesha.
