Ushwankathelo

I-Photorefractive keratectomy (PRK) luhlobo lotyando lwamehlo lwe-laser. Isetyenziselwa ukuphucula umbono ngokulungisa iimpazamo ezibonakalisayo kwiliso.

Ukubona ngaphambili, ukubona kude, kunye ne-astigmatism yonke imizekelo yeempazamo ezibonakalisayo. Ngokusekwe kwiimfuno zakho, unokuba noqhaqho lwe-PRK olwenziwe kwelinye okanye omabini amehlo.

I-PRK ilungiselela utyando lwe-LASIK kwaye yinkqubo efanayo. Zombini i-PRK kunye ne-LASIK zisebenza ngokubumba kwakhona i-cornea, eyindawo ecacileyo ngaphambili yeliso. Oku kuphucula ukubonwa kweliso.

Abanye abantu abagqatswa abafanelekileyo kuzo zombini i-PRK kunye ne-LASIK. Abanye bafaneleke ngakumbi kwenye okanye kwenye. Kubalulekile ukuqonda inkqubo ye-PRK kwaye yahluke njani kwi-LASIK ngaphambi kokuthatha isigqibo sokuba yeyiphi eyona ilungele wena. Ukuba ulungele ukulahla iiglasi zakho zamehlo okanye abafowunelwa, yile nto kufuneka uyazi.

Inkqubo yePRK

Uya kuxoxa ngezikhokelo zenkqubo ethile ye-PRK nogqirha wakho ngaphambi komhla wotyando. Kukho amanyathelo aliqela oya kuyalelwa ukuba uwathathe.

Phambi kotyando

Uya kuba nokuqeshwa kwangaphambili ukuze uhlolwe amehlo akho kwaye uvavanywe umbono wakho. Ukulungiselela utyando, impazamo ekhutshiweyo kunye nomfundi kwiso ngalinye ziya kulinganiswa kunye nemilo ye-corneal imephu. I-laser esetyenziswe ngexesha lenkqubo yakho iya kulungiswa ngolu lwazi.

Yazisa ugqirha wakho nangaliphi na iyeza kunye namayeza owasebenzisayo. Kuya kufuneka uyeke okwethutyana ukuzithatha. Ukuba usebenzisa i-antihistamines, ugqirha wakho unokukuxelela ukuba uyeke ukuzithatha iintsuku ezintathu ngaphambi komhla wokucwangciswa kotyando.

Ukuba unxibe iilensi ezingqingqwa zerhasi eqinileyo, ugqirha wakho uza kukuxelela ukuba uyeke ukuzinxiba ubuncinci iiveki ezintathu ngaphambi kotyando. Ezinye iintlobo zeelensi zonxibelelwano kufuneka ziyekwe, zihlala kwiveki enye ngaphambi kwenkqubo.

Ugqirha wakho unokumisela i-antibiotic eye eye, njengeZymaxid, ukuze uqale ukusebenzisa iintsuku ezintathu ukuya kwezine ngaphambi kotyando. Uya kuqhubeka ukuthatha ezi emva kwenkqubo ejikeleze iveki enye. Ugqirha wakho unokucebisa ngeliso lokuhla kwamehlo owomileyo.

Malunga neentsuku ezintathu ngaphambi kotyando, kuyakufuneka uqale ngokucoceka ngapha nangapha kwamehlo akho, aya kukhupha amadlala eoyile akufutshane nomgca wakho wokuqhuma:

1. Beka icompress eshushu okanye eshushu emehlweni akho imizuzu emihlanu.
2. Ngenisa ngobunono umnwe wakho kwinkophe yakho ephezulu ukusuka ngaphakathi kufutshane nempumlo yakho uye ngaphandle kufutshane nendlebe yakho. Yenza oku kabini okanye kathathu kwimigca ephezulu kunye nezantsi.
3. Hlamba iinkophe zakho kunye neenkophe kakuhle ngesepha esimnene, esingaphazamisiyo okanye ishampu yosana.
4. Phinda yonke inkqubo kabini ngosuku.

Usuku lotyando

Awuyi kuba nakho ukuqhuba kwaye unokuziva udinwe kakhulu emva kwe-PRK, ke yenza amalungiselelo okuba umntu othile akuthathe emva kwenkqubo.

Ngumbono olungileyo ukutya ukutya okulula ngaphambi kokuba ufike. Kuya kufuneka ulindele ukuba usekliniki iiyure ezininzi. Ngaphandle kokuba uxelelwe ngenye indlela, thatha amayeza akho aqhelekileyo amiselweyo.

Musa ukunxiba izithambiso okanye nantoni na enokuphazamisa amandla ogqirha wokubeka intloko yakho phantsi kwelaser. Ezinye izixhobo zokuphepha zibandakanya i-barrette, izikhafu, namacici.

Nxiba iimpahla ezintle kwinkqubo yakho. Ukuba uyagula, yiba nefiva, okanye ungaziva mnandi nangayiphi na indlela, tsalela ugqirha wakho ubuze ukuba ngaba le nkqubo kufuneka iqhubeke na.

Buza ugqirha wakho ukuba kufanelekile na ukuhambisa amathontsi wamehlo okanye naliphi na iyeza.

Inkqubo yoqhaqho

I-PRK ithatha imizuzu emi-5 ukuya kweli-10 ngeliso ngalinye. Olu hlobo lotyando aludingi kubulawa ngokubanzi. Unokunikwa i-anesthesia yendawo okanye i-anesthetic eye eye kwiso ngalinye.

Ngexesha lenkqubo:

1. Isibambi sejwabu leso siya kubekwa kwiliso ngalinye ukukugcina ungakhanyazi.
2. Ugqirha uya kususa kwaye alahle iiseli zomphezulu wamehlo akho. Oku kunokwenziwa nge-laser, blade, solution yotywala, okanye ngebrashi.
3. I-laser eyacwangciswa ngamehlo akho imilinganiselo iya kuyila kwakhona i-cornea nganye, isebenzisa i-pulsing boram ye-ultraviolet light. Unokuva uthotho lweebhiphu ngelixa kusenziwa oku.
4. Ilensi yokunxibelelana ecacileyo, engabhalwanga iya kubekwa kwiliso ngalinye njengebhanti. Oku kuyakugcina amehlo akho ecocekile, ukuthintela usulelo ngexesha lokuphilisa. Iilensi zonxibelelwano zebandage ziya kuhlala emehlweni akho iintsuku ezininzi ukuya kwiveki enye.

Iziphumo ebezingalindelekanga ze-PRK

Unokulindela ukuba uzive ungonwabanga okanye iintlungu ukuya kwiintsuku ezintathu emva kotyando lwe-PRK. Amayeza eentlungu angaphaya kwekhawuntari ahlala anele ekusingatheni le ngxaki.

Ukuba unenkxalabo malunga nentlungu okanye uva iintlungu ezingaphezulu kunokuba unakho, cela ugqirha wakho amayeza eentlungu amiselweyo. Amehlo akho anokuziva ecaphukile okanye amanzi.

Ungafumanisa ukuba amehlo akho anochuku ekukhanyeni ngelixa baphola. Abanye abantu bakwabona iihalos okanye ukugqabhuka kokukhanya kangangeentsuku okanye iiveki ezilandela iPRK, ngakumbi ebusuku.

Unokuba namava e-corneal haze, ingqimba enamafu enokuthintela kakhulu umbono, ixesha elifutshane emva kotyando.

Ngelixa kuthathwa njengokukhuselekileyo, utyando lwe-PRK alunabungozi. Iingozi zibandakanya:

• ukulahleka kombono ongenakulungiswa ngeendondo zamehlo okanye iilensi zonxibelelwano
• utshintsho olusisigxina kumbono wobusuku obandakanya ukubona ilitha kunye neehosos
• umbono kabini
• iliso eliqatha okanye elisisigxina elomileyo
• iziphumo ezinciphileyo ngokuhamba kwexesha, ngakumbi kubantu abadala nakwababona kude

Ukubuyiselwa kwe-PRK

Emva kotyando, uyophumla ekliniki emva koko uye ekhaya. Musa ukucwangcisa enye into ngalo mhla ngaphandle kokuphumla. Ukugcina amehlo akho evaliwe kunokunceda ekubuyiseni kunye nenqanaba lakho lokuthuthuzela.

Ugqirha unokunqwenela ukukubona kusuku olulandelayo emva kwenkqubo yokuvavanya iziphumo kunye nenqanaba lakho lokuthuthuzela. Shayela ugqirha wakho ngokukhawuleza ukuba ubona naziphi na iimpawu zentsholongwane yamehlo, njenge:

• bomvu
• ubofu
• ukudumba
• ifiva

Yazisa ugqirha wakho kwangoko ukuba ilensi yokuqhagamshela ibhandeji ikhutshiwe okanye iyawa. Kuya kufuneka ubuye ngaphakathi kweentsuku ezisixhenxe ukuze ususe iilensi emehlweni akho.

Ekuqaleni, umbono wakho ungangcono kunokuba wawunjalo ngaphambi kwenkqubo. Iya kuthi, nangona kunjalo, ifiphale kancinci ngeentsuku zokuqala zokuchacha. Emva koko iya kuphucula kakhulu. Abantu abaninzi baqaphela ukuphuculwa kombono xa beshenxisiwe iilensi zokudibanisa.

Musa ukurabha amehlo akho okanye ukukhupha abafowunelwa abagubungeleyo. Gcina izinto zokuthambisa, isepha, ishampu, kunye nezinye izinto ngaphandle kwamehlo akho kangangeveki. Buza ugqirha wakho xa unokuhlamba ubuso bakho ngesepha okanye usebenzise ishampu.

Ugqirha wakho unokucebisa ukuba uthathe ixesha lokuphumla ngelixa amehlo akho ephila. Thetha nogqirha wakho malunga nokuqhuba, ukufunda, kunye nokusetyenziswa kwekhompyuter. Ezi ntlobo zemisebenzi ziya kuba nzima ekuqaleni. Ukuqhuba kufuneka kuthintelwe de amehlo akho angacaci, ngakumbi ebusuku.

Zama ukuba ungafumani ukubila emehlweni akho ubuncinci iveki, kuba oku kunokubangela ukucaphuka. Musa ukuthatha inxaxheba kwimidlalo yokunxibelelana okanye nakweyiphi na into enokubangela ukonakala kwamehlo akho ubuncinci inyanga.

Ukunxiba izixhobo zokukhusela iliso kangangeenyanga ezininzi ngumbono olungileyo. Ukuqubha kunye neminye imidlalo yezamanzi kufuneka kuthintelwe iiveki ezininzi, nkqu nangogogo.Zama ukuba ungafumani uthuli okanye ukungcola emehlweni akho ngeli xesha linye.

Kungathatha iiveki ezimbalwa ngaphambi kokuba umbono wakho uzinze ngokupheleleyo. Umbono uhlala uphucula malunga neepesenti ezingama-80 emva kwenyanga enye, kunye neepesenti ezingama-95 ngenqaku leenyanga ezintathu. Phantse iipesenti ezingama-90 zabantu banombono we-20/40 okanye bhetele ngeenyanga ezintathu emva kotyando.

Khusela amehlo akho elangeni malunga nonyaka. Uya kudinga ukunxiba iiglasi zelanga ezingabhaliswanga.

Iindleko ze-PRK

Iindleko ze-PRK ziyahluka ngokusekwe apho uhlala khona, ugqirha wakho, kunye nemeko ethile. Ngokomndilili, unokulindela ukuhlawula naphi na ukusuka kwi- $ 1,800 ukuya kwi- $ 4,000 yoqhaqho lwe-PRK.

I-PRK vs LASIK

I-PRK kunye ne-LASIK bobabini bayilelwe ukulungisa iingxaki zombono wokuphinda babumbe ngokutsha i-cornea. Zombini ezi nkqubo zisebenzisa i-lasers kwaye zithathe ixesha elifanayo ukwenza.

Nge-PRK, ugqirha wotyando ususa kwaye alahle umaleko we-epithelial wangaphandle we-cornea, oshiya iliso libhencekile, ngaphambi kokubumba kwakhona i-cornea. Olu luhlu luyazihlaziya kwaye lukhule lubuye emva kwexesha.

Nge-LASIK, ugqirha wotyando wenza i-flap ngaphandle komaleko we-epithelial kwaye uyishenxise endleleni ukuze abumbe kwakhona i-cornea phantsi. I-flap idla ngokwenziwa nge-laser engenabala. Ihlala iqhotyoshelwe kwi-cornea kwaye ibuyiselwa endaweni emva kokuba inkqubo igqityiwe.

Ukuze ufanelekele utyando lwe-LASIK, kuya kufuneka ube nezicwili ezoneleyo zokwenza i-flap. Ngesi sizathu, i-LASIK isenokungakulungeli abantu abanombono ombi kakhulu okanye ii-corneas ezincinci.

Iinkqubo zikwahluka ngokwexesha lokuchacha kunye neziphumo ebezingalindelekanga. Ukubuyisela kwimeko yesiqhelo kunye nokuzinzisa umbono kuhamba kancinci nge-PRK kunokuba kunjalo ngoqhaqho lwe-LASIK. Abantu abane-PRK banokulindela ukuba bazive bengonwabanga emva koko kwaye babe neziphumo ebezingalindelekanga, ezinje ngehashe lehashe.

Amanqanaba empumelelo ayafana kuzo zombini iinkqubo.

Ukulunga kwePRK

• kungenziwa kubantu abane-corneas ezincinci okanye izicubu ezincinci ze-corneal ezibangelwa ukungaboni kakuhle okanye ukubona kwangaphambili
• umngcipheko omncinci wokususa inwebu eninzi kakhulu
• ibiza kancinci kuneLASIK
• umngcipheko omncinci weengxaki ezibangelwa kukucofa
• iliso elomileyo kunqabile ukuba libangelwe kuqhaqho lwePRK

PRK bendlela

• ukuphilisa kunye nokubuyiswa kokubonakalayo kuthatha ixesha elide kuba umaleko ongaphandle wekhoba kufuneka uzihlaziye kwakhona
• umngcipheko ophakamileyo wosulelo kuneLASIK
• umbono ocacileyo, ukungonwabi, kunye nemvakalelo yokukhanya zihlala zinamava ngelixa unxibe iilensi zonxibelelwano zebhendi ngexesha lokuchacha

Yeyiphi inkqubo ekulungeleyo?

I-PRK kunye ne-LASIK zombini zithathwa njengeenkqubo ezikhuselekileyo nezisebenzayo eziphucula kakhulu umbono. Ukuthatha isigqibo phakathi kwaba babini kunokuba nzima ngaphandle kokuba uneemeko ezithile ezifuna ukuba wenze enye okanye enye.

Ukuba une-corneas encinci okanye ukungaboni kakuhle, ugqirha wakho uya kukukhokela kwi-PRK. Ukuba ufuna ukubuyela ngokukhawuleza, i-LASIK inokuba lukhetho olungcono.
