Ngaba ukhe watyandwa i-cataract waza umbono wakho waphinda waba luzizi, ngokungathi ukwinkungu ? Abantu abaninzi bayaxhalaba ngeli xesha baze bacinge, "Hayi bo, ingaba i-cataract yam iyabuya?" Kodwa oku akusiyo into yokuba i-cataract iphinde ivele kwakhona. Ngokwezonyango, le meko siyibiza ngokuba yi-'Posterior Capsule Opacification' okanye i-PCO. Akukho nto yokukhathazeka ngayo, kuba isisombululo esilula, esingenabuhlungu nesikhawulezayo lunyango lwe-YAG laser.
Yintoni i-YAG Laser Capsulotomy?
Ngamafutshane, olu lunyango olukhawulezayo nolulula lwelaser lokubona okufipheleyo okwenzeka emva kotyando lwe-cataract.
Khawuthelekelele, ngexesha lotyando lwe-cataract, sisusa ilensi yendalo engaphakathi kweliso lakho, ebeliguquguquka ngokuhamba kwexesha, size siyitshintshe ngelensi yokwenziwa (Intraocular Lens - IOL). Le lensi intsha yokwenziwa ayinakukwazi ukudada ngaphakathi kweliso lakho. Ibanjwe endaweni yayo 'sisigqubuthelo' esincinci kakhulu, esifana ne-membrane (i-lens capsule) esasigcina ilensi yakho endala yendalo.
Kwiinyanga okanye iminyaka embalwa emva kotyando, kwabanye abantu , ezinye zeeseli eziseleyo ngasemva kwale capsule ziyakhula kwaye ziqala ukuba namafu, njengeglasi enothuli. Yiloo nto siyibiza ngokuba yi-PCO (Posterior Capsule Opacification).
Unyango lwelaser lwe-YAG lusebenzisa umqadi welaser okhethekileyo ukwenza umngxuma omncinci phakathi komaleko obhityileyo wezicubu ezinamafu, ngaphandle kokonakalisa iliso. Oku kuvumela ukukhanya ukuba kudlule elisweni ngaphandle kokuphazanyiswa, kwaye umbono wakho uyabuyiselwa. Ilaser esetyenziselwa oku ibizwa ngokuba yi-'YAG` (yttrium aluminium garnet) ngenxa yohlobo olukhethekileyo lwelitye elinqabileyo elenziwe ngalo.
Ndingayilungiselela njani le nyango?
Oku akudingi lungiselelo likhethekileyo. Le asiyonkqubo yokulaliswa esibhedlele, kodwa yindlela yokulaliswa esibhedlele enokwenziwa eofisini kagqirha wamehlo.
Xa usiya ekliniki ngosuku olucwangcisiweyo, imizuzu embalwa ngaphambi konyango, umongikazi uza kuza aze afake iintlobo ezimbini zamathontsi emehlweni akho.
1. Amayeza okubulala amehlo: Oku kuthetha ukuba awuyi kuva ntlungu ngexesha lonyango.
2. Amathontsi avulekayo: Oku kwenza kube lula kugqirha ukubona ilensi engaphakathi kweliso ngokucacileyo.
Nje ukuba la mathontsi asebenze, ukulungele ngokupheleleyo unyango.
Kwenzeka ntoni ngexesha lonyango?
Uhlala esitulweni, njengomatshini wokuvavanya amehlo, kwaye kufuneka uphumze isilevu sakho kunye nebunzi kuso uze ujonge phambili.
- Ukusebenzisa ilensi (mhlawumbi):Ngamanye amaxesha ugqirha angabeka ilensi ekhethekileyo phezu komphezulu weliso lakho aze ayibambe endaweni yayo. Igqunywe ngejeli, ukuze ungaziva ungonwabanga. Iliso lakho liza kuba ndindisholo, ngoko ke akukho ntlungu konke konke. Usenokuziva uxinezelekile kancinci.
- Ukusebenza kwelaser: Ugqirha uza kuyivula ilaser. Awuyi kuyibona imisebe yelaser okanye uve nayiphi na intlungu. Nangona kunjalo, ungasiva isandi esincinci esifana nelaser esithi 'tick, tick, tick' . Abanye abantu banokuziva ukukhanya ngequbuliso kwemibala eyahlukeneyo xa ilaser ibabetha. Oku kuqhelekile kwaye kuya kuphela kwimizuzu embalwa.
Lonke eli qhinga lithatha ngaphantsi kwemizuzu emi-5-10, kwaye ungagoduka kwangoko emva kokuba ligqityiwe.
Zithini iingenelo zolu nyango?
Kukho izizathu ezahlukeneyo zokuba kutheni abantu abaninzi bekhetha unyango lwe-YAG nge-laser.
| Inzuzo | Inkcazo elula |
|---|---|
| Ikhuselekile kakhulu | Umngcipheko weengxaki uphantsi kakhulu. Nokuba ziyenzeka, zihlala zincinci kwaye kulula ukuzinyanga. |
| Iphumelele kakhulu | Uphando lubonise ukuba abantu abangaphezu kwama-95 kwabayi-100 abafumana olu nyango banembono ecacileyo. |
| Akukho mfuneko yokuhlala esibhedlele. | Olu lunyango olunikezelwa ngaphandle kwesibhedlele. Ungaya ekhaya emva konyango. |
| Akukho ntlungu/ukungonwabi | Ekubeni iliso lindindisholo, awuyi kuva ntlungu okanye ukungakhululeki ngexesha lonyango. |
| Akukho bundlobongela kangako | Le yindlela elula kakhulu kunotyando lokwenyani kuba yenziwa kuphela ngemitha yelaser, ngaphandle kokwenza i-incision esweni. |
Ngaba kukho naziphi na iingxaki ezinokubakho?
Iingxaki ezinzima emva konyango lwe-YAG nge-laser azixhaphakanga. Ukuba ziyenzeka, zihlala zincinci kwaye zinokunyangwa.
- IiFloaters: Kuqhelekile ukubona amachaphaza amancinci amnyama okanye imisonto ihamba phambi kwamehlo akho (i-myodesopsias) kangangeentsuku ezimbalwa emva konyango. La ngamaqhekeza amancinci eqokobhe lelensi aqhekeka yilaser. La maqhekeza aya kuziphelela kwiintsuku okanye kwiiveki ezimbalwa.
Ngaphandle koku, kukho nezinye iingxaki ezininzi ezinokwenzeka ngokungaqhelekanga.
- Ukudumba ngaphakathi kweliso (`Uveitis`)
- Ukudumba kwe-retina (`i-Cystoid macular edema`)
- Ukuqhekeka kwe-retinal
- Ukukrazula kwe-retina
Khumbula ukuba ezi ziimeko ezingaqhelekanga kakhulu.
Ndifanele ndimbone ugqirha nini ngoko nangoko?
Ngokwesiqhelo, akukho mfuneko yokulandelela okukhethekileyo emva konyango lwe-YAG nge-laser. Uvavanyo lwakho lwamehlo rhoqo ngonyaka lwanele. Nangona kunjalo, ukuba ufumana naziphi na iimpawu ezilandelayo, isenokuba yimeko efuna unyango olukhawulezileyo.
Kubaluleke kakhulu: Ukuba ufumana naziphi na kwezi mpawu, isenokuba yingxamiseko. Ngoko ke yiya kwiSebe lezeMpilo eziNgxamisekileyo lesibhedlele (ETU) ngokukhawuleza okanye wazise ugqirha wakho wamehlo ngokukhawuleza.
- Ukukhanya okukhawulezileyo ngaphakathi kweliso (photopsias).
- Ngequbuliso ndibona inani elikhulu lee-'floaters' (amachaphaza amnyama/imisonto). (Kuqhelekile ukubona ezimbalwa, kodwa xhalaba ukuba ubona ezininzi ngaxeshanye.)
- Kubonakala ngathi elinye icala lombono ligqunywe ngumkhusane omnyama.
- Ukulahlekelwa ngumbono ngequbuliso.
Ezi mpawu zinokubangelwa yimeko embi ebizwa ngokuba yi-retinal detachment. Ukuba ayinyangwa ngokukhawuleza, umbono kwelo liso unokulahleka ngonaphakade. Kungoko ke, kubaluleke kakhulu ukuzazi ezi mpawu.
Umyalezo Wokuya Ekhaya
- I-post-op keratoplasty (PCO) yimeko eqhelekileyo enokwenzeka ngokuhamba kwexesha emva kotyando lwe-cataract. Oku akukokubuyela kwakhona kwe-cataract.
- Unyango lwe-YAG nge-laser yindlela ekhawulezayo, engenabuhlungu, nekhuselekileyo yokuphelisa olu lwazi lufipheleyo.
- Lonke olu nyango luthatha ngaphantsi kwemizuzu eli-10, kwaye ungagoduka ngaloo mini inye.
- Iingxaki ezinkulu azixhaphakanga, kodwa qaphela iimpawu ezingxamisekileyo ezifana nokukhanya emehlweni kunye nokucinywa kokukhanya.
- Ukuba unenkxalabo okanye uloyiko malunga noku, nceda uthethe nogqirha wakho wamehlo ngaphandle kokuthandabuza.
