Uke wahlinzwa i-cataract futhi umbono wakho usufiphele futhi, njengokungathi usenkungwini ? Abantu abaningi bakhathazekile ngalesi sikhathi futhi bacabanga ukuthi, "Hawu, ingabe i-cataract yami iyabuya?" Kodwa empeleni lokhu akuyona into ephinde ivele. Ngokwezokwelapha, lesi simo sibizwa ngokuthi 'i-Posterior Capsule Opacification' noma i-PCO. Akukho okufanele ukhathazeke ngakho, ngoba ikhambi elilula, elingenabuhlungu nelisheshayo ukwelashwa nge-laser ye-YAG.
Kuyini i-YAG Laser Capsulotomy?
Kalula nje, lokhu kuyindlela yokwelapha eshesha kakhulu futhi elula nge-laser yokungaboni kahle okwenzeka ngemva kokuhlinzwa kwe-cataract.
Cabanga nje, ngesikhathi sokuhlinzwa kwe-cataract, sisusa ilensi yemvelo engaphakathi kweso lakho, eseyiguqubele njengoba ikhula, bese siyishintsha ngelensi yokwenziwa (Intraocular Lens - IOL). Le lensi entsha yokwenziwa ayikwazi ukuntanta ngaphakathi kweso lakho. Ibanjwe endaweni yayo 'yisivikelo' esincane kakhulu, esifana ne-membrane (i-lens capsule) esasigcina ilensi yakho endala yemvelo.
Ezinyangeni ezimbalwa noma eminyakeni ngemva kokuhlinzwa, kwabanye abantu , amanye amangqamuzana asele ngemuva kwale capsule ayakhula futhi aqale ukuba namafu, njengengilazi enothuli. Yilokho esikubiza ngokuthi i-PCO (Posterior Capsule Opacification).
Ukwelashwa nge-laser ye-YAG kusebenzisa umsebe we-laser okhethekile ukudala imbobo encane phakathi kwengqimba encane yezicubu ezinamafu, ngaphandle kokulimaza iso. Lokhu kuvumela ukukhanya ukuthi kudlule esweni ngaphandle kokuvinjelwa, futhi umbono wakho uyabuyiselwa. I-laser esetshenziselwa lokhu ibizwa ngokuthi i-`YAG` (yttrium aluminium garnet) ngenxa yohlobo olukhethekile lwetshe eliyigugu elenziwe ngalo.
Ngingakulungiselela kanjani lokhu kwelashwa?
Lokhu akudingi noma yikuphi ukulungiselela okukhethekile. Lena akuyona inqubo yokulaliswa esibhedlela, kodwa inqubo yokulaliswa esibhedlela engenziwa ehhovisi likadokotela wamehlo.
Uma uya emtholampilo ngosuku oluhleliwe, imizuzu embalwa ngaphambi kokwelashwa, umhlengikazi uzofika afake izinhlobo ezimbili zamaconsi amehlo emehlweni akho.
1. Umuthi wokuqeda izinhlungu zamehlo: Lokhu kusho ukuthi ngeke uzwe ubuhlungu ngesikhathi sokwelashwa.
2. Amaconsi avulekayo: Lokhu kwenza kube lula ngodokotela ukubona ilensi ngaphakathi kweso ngokucacile.
Uma la maconsi eseqalile ukusebenza, usukulungele ngokuphelele ukwelashwa.
Kwenzekani ngesikhathi sokwelashwa?
Uhlala esihlalweni, njengomshini wokuhlola amehlo, futhi kufanele ubeke isilevu sakho nebunzi kuso bese ubheka phambili.
- Ukusebenzisa ilensi (mhlawumbe):Ngezinye izikhathi udokotela angase abeke ilensi ekhethekile ebusweni belihlo lakho bese elibamba endaweni yalo. Limbozwe ngejeli, ukuze ungazizwa ungakhululekile. Ihlo lakho lizoba ndikindiki, ngakho-ke akukho buhlungu nhlobo. Ungase uzizwe ucindezelekile kancane.
- Ukusebenza kwe-laser: Udokotela uzobe esevula i-laser. Ngeke uwubone umsebe we-laser noma uzwe ubuhlungu. Kodwa-ke, ungase uzwe umsindo omncane ofana ne-laser othi 'tick, tick, tick' . Abanye abantu bangase bezwe ukukhanya okungazelelwe kwemibala ehlukene lapho i-laser ibashaya. Lokhu kuvamile futhi kuzophela ngemizuzu embalwa.
Yonke inqubo ithatha imizuzu engaphansi kwemi-5-10, futhi ungaya ekhaya ngokushesha nje lapho isiqediwe.
Ziyini izinzuzo zalokhu kwelashwa?
Kunezizathu eziningana ezenza abantu abaningi bakhethe ukwelashwa nge-laser ye-YAG.
| Inzuzo | Incazelo elula |
|---|---|
| Kuphephile kakhulu | Ingozi yezinkinga iphansi kakhulu. Ngisho noma zingenzeka, zivame ukuba zincane futhi kulula ukuzelapha. |
| Kuphumelele kakhulu | Ucwaningo lukhombisile ukuthi abantu abangaphezu kuka-95 kwabayi-100 abathola lokhu kwelashwa banombono ocacile kakhulu. |
| Asikho isidingo sokuhlala esibhedlela. | Lokhu ukwelashwa kwangaphandle. Ungaya ekhaya ngemva kokwelashwa. |
| Akukho ubuhlungu/ukungakhululeki | Njengoba iso lingenamizwa, ngeke uzizwe ubuhlungu noma ukungakhululeki ngesikhathi sokwelashwa. |
| Akunalo ulaka oluningi | Lena indlela elula kakhulu kunokuhlinzwa kwangempela ngoba yenziwa kuphela ngemisebe ye-laser, ngaphandle kokusika iso. |
Ingabe zikhona izinkinga ezingaba khona?
Izinkinga ezinkulu ngemva kokwelashwa nge-laser ye-YAG azivamile. Uma zenzeka, ngokuvamile ziba zincane futhi ziyalapheka.
- Ama-Floater: Kuvamile ukubona amachashazi amancane amnyama noma imicu ihamba phambi kwamehlo akho (ama-myodesopsias) izinsuku ezimbalwa ngemva kokwelashwa. Lezi yizingcezu ezincane zegobolondo lelensi eziqhekeka yi-laser. Lezi zizophela zodwa phakathi nezinsuku noma amasonto ambalwa.
Ngaphandle kwalokhu, kunezinye izinkinga eziningana ezingavela kaningi.
- Ukuvuvukala ngaphakathi kweso (`Uveitis`)
- Ukuvuvukala kwe-retina (`i-Cystoid macular edema`)
- Ukuhlukaniswa kwe-retinal
- Ukudabuka kwe-retinal
Khumbula ukuthi lezi yizimo ezingavamile kakhulu.
Ngingayibona nini udokotela ngokushesha?
Ngokuvamile, akudingeki ukulandelela okukhethekile ngemva kokwelashwa nge-laser ye-YAG. Ukuhlolwa kwamehlo kwakho okuvamile kwaminyaka yonke kwanele. Kodwa-ke, uma uhlangabezana nanoma yiziphi izimpawu ezilandelayo, kungaba yisimo esidinga ukunakekelwa kwezokwelapha okuphuthumayo.
Kubaluleke kakhulu: Uma uhlangabezana nanoma yiziphi zalezi zimpawu, kungaba yisimo esiphuthumayo. Ngakho-ke iya eMnyangweni Wezimo Eziphuthumayo wesibhedlela (ETU) ngokushesha noma wazise udokotela wakho wamehlo ngokushesha okukhulu.
- Ukukhanya okungazelelwe ngaphakathi kweso (i-photopsias).
- Ngokungazelelwe ngibona inani elikhulu 'lama-floater' (amachashazi amnyama/imicu). (Kuyinto evamile ukubona ambalwa, kodwa khathazeka uma ubona amaningi ngesikhathi esisodwa.)
- Kubonakala sengathi uhlangothi olulodwa lombono lumbozwe yikhethini elimnyama.
- Ukulahlekelwa umbono ngokuzumayo.
Lezi zimpawu zingabangelwa yisimo esibi esibizwa ngokuthi i-retinal detachment. Uma singelashwa ngokushesha, umbono kulelo liso ungase ulahleke unomphela. Ngakho-ke, kubaluleke kakhulu ukuqaphela lezi zimpawu.
Umlayezo Wokuya Nawe Ekhaya
- I-Post-op keratoplasty (PCO) yisimo esivamile esingase senzeke ngokuhamba kwesikhathi ngemva kokuhlinzwa kwe-cataract. Lokhu akusikho ukuphinda kwe-cataract.
- Ukwelashwa nge-laser ye-YAG kuyindlela esheshayo, engenabuhlungu, futhi ephephile yokuqeda lo mbono ofiphele.
- Lonke lolu hlobo lokwelashwa luthatha imizuzu engaphansi kweyi-10, futhi ungaya ekhaya ngalolo suku.
- Izinkinga ezinkulu azivamile, kodwa qaphela izimpawu eziphuthumayo njengokukhanya emehlweni kanye nokucinywa kokukhanya.
- Uma unemibuzo noma ukwesaba ngalokhu, sicela ukhulume nodokotela wakho wamehlo ngaphandle kokungabaza.
