Ngaba udiniwe kukukhangela iiglasi zakho okanye iilensi zokunxibelelana qho kusasa emva kokuvuka? Ngaba udiniwe kukuzimanzisa iiglasi zakho xa lina, zigcwele inkungu, kwaye kufuneka uzicoce rhoqo? Mhlawumbi ungumntu wezemidlalo, kwaye ke ezi glasi ziyinkinga enkulu. Abantu abaninzi bacinga ukuba akukho sisombululo koku, kangangokuba kufuneka uphile ngolu hlobo ubomi bakho bonke. Kodwa eneneni, kukho iindlela zonyango zanamhlanje ezinokuvalelisa ezi glasi kwaye zikhanyise umbono wakho . Namhlanje sithetha ngotyando olulodwa olukhethekileyo.
Yintoni kanye kanye iRefractive Lens Exchange (RLE)?
Ngamafutshane, olu lutyando lwamehlo. Nangona kunjalo, oku kuquka ukususa ngokupheleleyo ilensi yendalo engaphakathi kweliso lakho kunye nokufaka ilensi yokwenziwa (Intraocular Lens - IOL ) ngokusisigxina eyenzelwe ukulingana nesiphene sakho sokubona.
Cinga ngokuba nelensi encinci enamandla afanayo neeglasi zakho zamehlo okanye iilensi zoqhagamshelwano ezifakwe esweni lakho. Nje ukuba ilensi yokwenziwa ifakwe, isebenza njengelensi yakho yendalo. Igxila ukukhanya okungena elisweni lakho kwaye ikujolise ngqo kwi -retina . Oku kukuvumela ukuba ubone ngokucacileyo ngaphandle kokufiphala. Abantu abaninzi abasayi kuphinda banxibe iiglasi emva kolu tyando. Abanye abantu banokufuna iiglasi kuphela kwimisebenzi ekufutshane, njengokufunda incwadi okanye iphephandaba.
Usenokuba ukhe weva ngotyando lwelaser, olufana ne-`(LASIK)` kunye ne-`(PRK)`. Olu tyando lutshintsha imo ye-cornea yeliso ukuze kuphuculwe umbono. Kodwa abanye abantu, ingakumbi abo baneengxaki ezinkulu zokubona (ukubona okukufutshane okanye ukubona okukude), abanakwenza olu tyando lwelaser. Kulapho oogqirha bacebisa khona utyando lwe-`(Refractive Lens Exchange)`.
Ngubani olungele olu tyando? (Kwaye ngubani olungele lona?)
Olu tyando alulungelanga wonke umntu. Ugqirha wakho wamehlo uza kuhlola amehlo akho aze agqibe ukuba oku kulungile na kuwe. Itheyibhile engasezantsi iza kukunika umbono olungileyo ngalo mba.
| Ngubani ofanelekileyo kolu tyando? | Abantu abasenokungafaneleki kolu tyando |
|---|---|
| Abantu abane -myopia okanye i-hyperopia enzima eyenza utyando lwe-laser lungenzeki. | Abantu abaneengxaki ezichaphazela i-cornea yeliso. |
| Abantu abafuna ukunciphisa ukuxhomekeka kwabo kwiiglasi ngenxa ye -presbyopia, imeko eyenzeka xa abantu besaluphala. | Abantu abanokonakala kwe-macular okubangelwa kukwaluphala . |
| Abantu abane-astigmatism. | Abantu abane -retinopathy enxulumene nesifo seswekile . |
| Abo bafuna ukuphepha umngcipheko we-cataracts kwixesha elizayo. | Abantu abanobungozi bokuqhekeka kwe -retina . |
| Abantu abanesifo se- uveitis, isifo sokudumba esibonakala ngaphakathi kweliso. |
Ngaba ubudala bubalulekile?
Olu tyando ludla ngokuba lolona lufanelekileyo kubantu abaneminyaka engaphezu kwama-40. Zininzi izizathu zoku. Esinye kukuba abantu abadala abanakukwazi ukuba neengxaki emva kotyando. Esinye kukuba abantu abaninzi abaneminyaka engaphezu kwama-40 sele benomlinganiselo othile wokubona izinto ezikufutshane (presbyopia). Ngoko ke olu tyando lunokusombulula loo ngxaki ngaxeshanye.
Yintoni umahluko phakathi kotyando lwe-cataract kunye noku?
Le yinto abantu abaninzi abadidekile ngayo. Zombini ezi ndlela zotyando ziquka ukususa ilensi yendalo yeliso kunye nokuyifaka ilensi yokwenziwa (IOL). Nangona kunjalo, isizathu sotyando sahlukile ngokupheleleyo.
- Utyando lwe-cataract : Oku kwenziwa kuba ilensi yendalo eliso lakho iye yaba namafu (njengeglasi enenkungu). Oku kumafu kuphazamisa umbono wakho. Ngoko ke ilensi enamafu iyasuswa kwaye kufakwa ilensi ecacileyo yokwenziwa ukuze kubuyiselwe umbono ocacileyo. Oku kuyimfuneko kwezonyango.
- Utyando lweRefractive Lens Exchange (RLE): Oku kwenzelwa ukulungisa iingxaki zokubona (ezifana nokubona kufutshane okanye ukubona kude) ezenzeka xa ilensi yakho yendalo icacile , kodwa ingakwazi ukugxila ekukhanyeni ngokufanelekileyo. Ingxaki apha asikokufiphala kwelensi, kodwa yingxaki yokugxila . Oku kwenzelwa ukunciphisa ukuxhomekeka kwakho kwiiglasi okanye iilensi zoqhagamshelwano nokwenza ubomi bemihla ngemihla bube lula. Ke ngoko, olu lutyando olukhethwayo kunokuba lube yimfuneko yezonyango.
Uzilungiselela njani ngaphambi kotyando?
Ugqirha wakho wamehlo uza kuhlola amehlo akho kakuhle ngaphambi kotyando aze axoxe nawe ngeentlobo zeelensi zangaphakathi kweso (ii-IOL) ezinokufakelwa. Kubalulekile ukubuza nayiphi na imibuzo onokuba nayo ngeli xesha.
Yiba nolwazi olufanelekileyo malunga nokukhetha ilensi ye-intraocular (IOL) efanelekileyo kuwe. Buza ugqirha wakho malunga neenzuzo kunye nokungalungi kohlobo ngalunye lwelensi kunye nendlela eza kuyichaphazela ngayo ubomi bakho bemihla ngemihla.
Kukho iintlobo ezininzi eziphambili ze-IOLs:
- Ii-Monofocal IOLs: Ezi lensi zinokubonelela ngokubona okucacileyo xa umgama okanye xa umgama . Azinakubonelela zombini. Umzekelo, ukuba unxiba ezi lensi xa ubona umgama, ngokuqinisekileyo uya kuzidinga iiglasi xa usenza imisebenzi efana nokufunda incwadi okanye ukujonga ifowuni yakho.
- Ii-IOL ezininzi (iilensi ezibonelela ngomgama kunye nokubona kufutshane): Ezi lensi zikuvumela ukuba ubone umgama kunye nezinto ezikufutshane ngaphandle kweeglasi. Nangona kunjalo, zineengxaki ezithile. Abanye abantu banokufumana ukukhanya kunye nee-halos xa beqhuba ebusuku. Ezi zihlala zinyamalala ngokuhamba kwexesha.
- Indlela yeMonovision: Le yindlela enomdla kakhulu. Okwenzayo apha kukubeka ilensi ye-"monofocal"` yokujonga umgama kwelinye iliso kunye nelensi ye-"monofocal`` yokujonga umgama kwelinye iliso. Nangona kuvakala kungaqhelekanga ekuqaleni, emva kwexesha elithile ingqondo yakho iyaqhela oku kwaye uqala ukubona umgama kunye nomgama ngaphandle kokuqaphela.
Thetha nogqirha wakho ukuze akhethe ukuba zeziphi kwezi ndlela ezifanelekileyo kwindlela yakho yokuphila, umsebenzi wakho, kunye neemfuno zakho.
Lwenziwa njani utyando?
Akukho sizathu sokoyika olu tyando. Ludla ngokuthatha malunga nemizuzu eli-15-30 ukugqitywa. Amanyathelo abandakanyekayo kolu tyando ngala alandelayo:
1. Okokuqala , amaconsi amehlo afakwa kwiliso lakho ukuze alivale amehlo . Ngoko awuyi kuva ntlungu. Ukuba kuyimfuneko, unganikwa iyeza lokuthomalalisa ukuze uhlale uzolile. Uya kuba nengqondo, kodwa umbono wakho uya kuba luzizi. Okukuphela kwento onokuyibona kukukhanya kunye nentshukumo ethile.
2. Okulandelayo, ugqirha usebenzisa umqadi welaser okanye ibala elincinci kakhulu ukwenza umngxuma omncinci kakhulu apho umhlophe weliso (i-sclera) kunye ne-cornea kudibana khona.
3. Emva koko, usebenzisa isixhobo esimile okwepeni (i-phacoemulsification), ilensi yakho yendalo iyaphulwa ibe ziingceba ezincinci ize itsalwe ngononophelo.
4. Ngoku, ilensi yokwenziwa ekhethiweyo ngaphambili (IOL) ifakwe kwindawo eyenziweyo ngaloo mngxuma mncinci kwaye ibekwe ngokuchanekileyo ngaphakathi kwekhaphukhaphu yelensi ethambileyo ebamba ilensi.
5. Olu luhlu luncinci kangangokuba aludingi nokuthungwa . Luza kuvala luze luphole ngokwalo.
6. Ekugqibeleni, uza kudluliselwa kwigumbi lokulinda unesikhuselo samehlo esincinci esiqhotyoshelweyo.
Kwenzeka ntoni emva kotyando?
Emva kotyando, uza kujongwa malunga nemizuzu engama-30 uze uvunyelwe ukuba ugoduke. Kubalulekile ukuba kubekho umntu oza kukuthatha akuse ekhaya. Kwakhona, kufuneka ube nomntu oza kukusa kwintlanganiso yakho yokuqala yekliniki emva kotyando. Ugqirha uza kukuxelela ukuba ungaphinda uqhube nini.
