Ukubuka konke

I-Photorefractive keratectomy (PRK) uhlobo lokuhlinzwa kwamehlo kwelaser. Isetshenziselwa ukuthuthukisa umbono ngokulungisa amaphutha we-refractive esweni.

Ukubona eduze, ukubona kude, kanye ne-astigmatism konke kuyizibonelo zamaphutha wokubuyisa. Ngokuya ngezidingo zakho, ungahle uhlinzwe nge-PRK kwelinye noma kuwo womabili amehlo.

I-PRK yandulela ukuhlinzwa kwe-LASIK futhi inqubo efanayo. Kokubili i-PRK ne-LASIK basebenza ngokwakha kabusha i-cornea, okuyingxenye ecacile engaphambili yeso. Lokhu kuthuthukisa ikhono leso lokugxila.

Abanye abantu bangabalingani abalungele i-PRK ne-LASIK. Abanye bafaneleke kangcono kokunye noma kokunye. Kubalulekile ukuqonda inqubo ye-PRK nokuthi yehluke kanjani kwi-LASIK ngaphambi kokunquma ukuthi yini ekufanele kakhulu. Uma usukulungele ukulahla izibuko zakho zamehlo noma oxhumana nabo, yilokhu okumele ukwazi.

Inqubo ye-PRK

Uzoxoxa ngemikhombandlela ethile yenqubo ye-PRK nodokotela wakho ngaphambi kosuku lwakho lokuhlinzwa. Kunezinyathelo eziningana ozokwaziswa ukuba uzithathe.

Ngaphambi kokuhlinzwa

Uzoba nokuqokwa ngaphambi kokuhlinzwa ukuze uhlolwe amehlo akho futhi kuhlolwe nombono wakho. Ukulungiselela ukuhlinzekwa, kuzolinganiswa iphutha elikhiphayo nomfundi esweni ngalinye bese umephu we-corneal wakhiwe. I-laser esetshenziswe ngesikhathi senqubo yakho izocutshungulwa ngalolu lwazi.

Yazisa udokotela wakho nganoma imiphi imishanguzo kadokotela oyisebenzisayo njalo oyisebenzisayo. Ungadinga ukumisa okwesikhashana ukuzithatha. Uma usebenzisa ama-antihistamine, udokotela wakho angakutshela ukuthi uyeke ukuwaphuza izinsuku ezintathu ngaphambi kosuku lwakho lokuhlinzwa oluhleliwe.

Uma ugqoka amalensi oxhumana nawo kagesi aqinile, udokotela wakho uzokutshela ukuthi uyeke ukuwagqoka okungenani amasonto amathathu ngaphambi kokuhlinzwa. Ezinye izinhlobo zamalensi wokuxhumana nazo kufanele ziyekwe, imvamisa kusasele isonto elilodwa ngaphambi kwenqubo.

Udokotela wakho angakunika i-eye eye elwa namagciwane, njenge-Zymaxid, ukuze uqale ukusebenzisa izinsuku ezintathu kuya kwezine ngaphambi kokuhlinzwa. Uzoqhubeka uthathe lokhu ngemuva kwenqubo cishe isonto elilodwa. Udokotela wakho futhi angancoma ukwehla kweso ngeso elomile.

Cishe izinsuku ezintathu ngaphambi kokuhlinzwa, kuzodingeka uqale uhlanze kahle amehlo akho, azokhipha izindlala zikawoyela eziseduze nomugqa wakho wokuqhuma:

1. Beka i-compress efudumele noma eshisayo emehlweni akho imizuzu emihlanu.
2. Gijimisa umunwe wakho ngobunono esigqokweni sakho esingenhla usuka ngaphakathi eduze kwempumulo yakho uye ngaphandle ngaphandle kwendlebe yakho. Yenza lokhu kabili noma kathathu kolayini abaphezulu nabaphansi.
3. Geza izinkophe zakho nezinkophe zakho kahle ngensipho emnene, engacasuli noma ngeshampu yomntwana.
4. Phinda yonke inqubo kabili ngosuku.

Usuku lokuhlinzwa

Ngeke ukwazi ukushayela futhi ungazizwa ukhathele kakhulu ngemuva kwe-PRK, ngakho-ke yenza amalungiselelo okuba nomuntu ozokulanda ngemuva kwenqubo.

Kungumqondo omuhle ukudla ukudla okulula ngaphambi kokuba ufike. Kufanele ulindele ukuba semtholampilo amahora amaningana. Ngaphandle kokuthi utshelwe ngenye indlela, thatha imishanguzo yakho ejwayelekile kadokotela.

Ungafaki izimonyo noma noma yini engaphazamisa ikhono likadokotela wokubeka ikhanda lakho ngaphansi kwelaser. Ezinye izesekeli ezizogwenywa zifaka ama-barrette, izikhafu namacici.

Gqoka izingubo ezikahle kwinqubo yakho. Uma ugula, unomkhuhlane, noma ungazizwa uphilile nganoma iyiphi indlela, shayela udokotela wakho bese ubuza ukuthi inqubo kufanele iqhubeke yini.

Buza udokotela wakho ukuthi kufanele uphathe amaconsi wamehlo noma yimuphi omunye umuthi.

Inqubo yokuhlinzwa

I-PRK ithatha imizuzu emi-5 ukuya kwengu-10 ngeso ngalinye. Lolu hlobo lokuhlinzwa aludingi i-anesthesia ejwayelekile. Unganikezwa i-anesthesia yendawo noma amaconsi esiso sokubulala izinzwa esweni ngalinye.

Ngesikhathi senqubo:

1. Isibambi sejwabu leso sizobekwa esweni ngalinye ukukugcina ungacwayizi.
2. Udokotela ohlinzayo uzosusa futhi alahle amangqamuzana angaphezulu weso leso lakho. Lokhu kungenziwa nge-laser, blade, isixazululo sotshwala, noma ibhulashi.
3. I-laser efakwe izilinganiso zamehlo akho izokwakha kabusha i-cornea ngayinye, isebenzisa umsebe odonsayo wokukhanya kwe-ultraviolet. Ungase uzwe uchungechunge lwama-beeps ngenkathi kwenziwa lokhu.
4. Ilensi yokuxhumana ecacile, engabhaliswanga izobekwa esweni ngalinye njengebhandeshi. Lokhu kuzogcina amehlo akho ehlanzekile, kugweme ukutheleleka ngesikhathi sokuphulukiswa. Amalensi okuxhumana ebhandeshi azohlala emehlweni akho izinsuku eziningana kuye kwesonto elilodwa.

Imiphumela emibi ye-PRK

Ungalindela ukuzwa ukungakhululeki noma ubuhlungu kuze kube yizinsuku ezintathu ngemuva kokuhlinzwa kwe-PRK. Imithi yezinhlungu ezithengiswa ekhawunteni ivame ukwanela ukusingatha le nkinga.

Uma ukhathazekile ngobuhlungu noma uzwa ubuhlungu obungaphezu kwamandla akho, cela udokotela wakho ngemithi yezinhlungu ebekiwe. Amehlo akho nawo angazizwa ecasukile noma amanzi.

Ungathola ukuthi amehlo akho azwela kakhulu ekukhanyeni ngenkathi esalulama. Abanye abantu babona futhi ama-halos noma ukuqhuma kokukhanya izinsuku noma amasonto alandela i-PRK, ikakhulukazi ebusuku.

Ungase futhi uhlangabezane ne-corneal haze, ungqimba lwamafu olungavimba kakhulu umbono, isikhathi esifushane ngemuva kokuhlinzwa.

Ngenkathi kubhekwa njengokuphephile, ukuhlinzwa kwe-PRK akuyona ingozi. Izingozi zifaka:

• ukulahleka kombono okungenakulungiswa ngezibuko zamehlo noma ama-lens oxhumana nawo
• ushintsho olungapheli kumbono wasebusuku ofaka phakathi ukubona ama-glare nama-halos
• ukubona kabili
• iso elomile noma eliqinile elomile
• imiphumela enciphile ngokuhamba kwesikhathi, ikakhulukazi kubantu abadala futhi ababona kude

Ukubuyiselwa kwe-PRK

Ngemuva kokuhlinzwa, uzophumula emtholampilo bese uya ekhaya. Ungahleli noma yini enye yalolo suku ngaphandle kokuphumula. Ukugcina amehlo akho evaliwe kungasiza ekululameni nasezingeni lakho lokunethezeka.

Udokotela angafisa ukukubona ngosuku olulandelayo ngemuva kwenqubo yokuhlola imiphumela nezinga lakho lokunethezeka. Shayela udokotela wakho ngokushesha uma ubona noma yiziphi izimpawu zokutheleleka kweso, njenge:

• ububomvu
• ubomvu
• ukuvuvukala
• imfiva

Yazisa udokotela wakho ngokushesha uma ilensi yokuxhumana yebhandeshi ikhishiwe noma iyawa. Uzodinga ukubuya zingakapheli izinsuku eziyisikhombisa ukuze ususe amalensi emehlweni akho.

Ekuqaleni, umbono wakho ungahle ube ngcono kunangaphambi kwenqubo. Kodwa-ke, kuzoba kufiphele ngandlela thile ezinsukwini ezimbalwa zokuqala zokululama. Ngemuva kwalokho izothuthuka kakhulu. Abantu abaningi babona ukuthuthuka kombono lapho kususwa amalensi abo okuxhumana nawo ebhandeshi.

Ungahlikihli amehlo akho noma ukhiphe oxhumana nabo obembozayo. Musa ukubeka izimonyo, insipho, imoto nezinye izinto emehlweni akho okungenani isonto. Buza udokotela wakho ukuthi ungageza nini ubuso ngensipho noma usebenzise i-shampoo.

Udokotela wakho angancoma ukuthatha ikhefu ngenkathi amehlo akho esaphola. Khuluma nodokotela wakho mayelana nokushayela, ukufunda nokusetshenziswa kwekhompyutha. Lezi zinhlobo zemisebenzi zizoba nzima ekuqaleni. Ukushayela kufanele kugwenywe kuze kube yilapho amehlo akho engasabonakali, ikakhulukazi ebusuku.

Zama ukungafikelwa umjuluko emehlweni akho okungenani isonto, ngoba lokhu kungadala ukucasuka. Ungabambi iqhaza emidlalweni yokuxhumana noma kunoma yimuphi umsebenzi ongadala ukulimala emehlweni akho okungenani inyanga eyodwa.

Ukugqoka okokuvikela iso izinyanga ezimbalwa kuwumqondo omuhle.Ukubhukuda neminye imidlalo yezamanzi kufanele kugwenywe amasonto ambalwa, noma ngabe kunezigqoko. Futhi, zama ukungafaki uthuli noma ukungcola emehlweni akho ngaleso sikhathi esifanayo.

Kungathatha amasonto ambalwa ngaphambi kokuba umbono wakho uzinze ngokuphelele. Umbono uvame ukuthuthuka cishe ngamaphesenti angama-80 ngemuva kwenyanga eyodwa, namaphesenti angama-95 ngezimpawu zezinyanga ezintathu. Cishe amaphesenti angama-90 wabantu anombono we-20/40 noma angcono ngezinyanga ezintathu ngemuva kokuhlinzwa.

Vikela amehlo akho elangeni elikhanyayo isikhathi esingangonyaka. Uzodinga ukugqoka izibuko zelanga ezingabhalisiwe ezinsukwini ezinelanga.

Izindleko ze-PRK

Izindleko ze-PRK ziyahlukahluka kuye ngokuthi uhlalaphi, udokotela wakho, kanye nemininingwane yesimo sakho. Ngokwesilinganiso, ungalindela ukukhokha noma yikuphi kusuka ku- $ 1,800 kuya ku- $ 4,000 ngokuhlinzwa kwe-PRK.

I-PRK vs. LASIK

I-PRK ne-LASIK zombili zenzelwe ukulungisa izinkinga zombono we-refractive ngokubumba kabusha i-cornea. Zombili izinqubo zisebenzisa ama-lasers futhi zithatha isikhathi esilinganayo zokwenza.

Nge-PRK, udokotela ohlinzayo ususa futhi alahle ungqimba lwe-cornea yangaphandle lwe-epithelial, olushiya iso livuliwe, ngaphambi kokubumba kabusha i-cornea. Lolu ungqimba luyazivuselela futhi lukhule lubuye ngokuhamba kwesikhathi.

Nge-LASIK, udokotela ohlinzayo udala i-flap aphume ungqimba lwe-epithelial bese eyisusa endleleni ukuze abumbe kabusha i-cornea ngaphansi. I-flap ivame ukwenziwa nge-laser engenamacici. Ihlala inamathiselwe ku-cornea futhi ibuyiselwa endaweni yayo ngemuva kokuthi inqubo isiqediwe.

Ukuze ufanelekele ukuhlinzekwa kwe-LASIK, kufanele ube nezicubu ezanele zamakholomu ukwenza lokhu kuchaphazeleke. Ngalesi sizathu, i-LASIK ingahle ingalungeli abantu abanombono ompofu kakhulu noma ama-corneas amancane.

Izinqubo futhi ziyehluka maqondana nesikhathi sokutakula nemiphumela engemihle. Ukuvuselelwa nokubuyiselwa komzimba kuthola kancane nge-PRK kunokuhlinzwa kwe-LASIK. Abantu abane-PRK nabo bangalindela ukuzwa ukungakhululeki okuningi ngemuva kwalokho futhi babe nemiphumela emibi eminingi, efana ne-corneal haze.

Izinga lokuphumelela liyafana kuzo zombili izinqubo.

Izinzuzo ze-PRK

• kungenziwa kubantu abane-corneas encane noma izicubu ezincane ze-corneal ezibangelwa ukungaboni kahle noma ukubona eduze okukhulu
• ingozi encane yokususa i-cornea eningi
• engabizi kakhulu kune-LASIK
• ingozi encane yezinkinga ezibangelwa i-flap
• iso elomile mancane amathuba okuthi livele ekuhlinzweni kwe-PRK

Ububi be-PRK

• ukuphulukiswa nokubuyiselwa kokubuka kuthatha isikhathi eside ngoba ungqimba lwangaphandle lwe-cornea ludinga ukuzivuselela
• ingozi ethe xaxa yokutheleleka kune-LASIK
• ukungaboni kahle, ukungakhululeki, nokuzwela ekukhanyeni kuvame ukuzwa ngenkathi ugqoke ilensi yokuxhumana yebhandeshi ngesikhathi sokululama

Iyiphi inqubo ekufanele kakhulu?

I-PRK ne-LASIK zombili zibhekwa njengezinqubo eziphephile nezisebenzayo ezithuthukisa kakhulu umbono. Ukunquma phakathi kwalezi zinto ezimbili kungaba nzima ngaphandle kokuthi unemibandela ethile edinga ukuthi wenze okukodwa noma okunye.

Uma une-corneas encane noma ukungaboni kahle, udokotela wakho uzokuqondisa ku-PRK. Uma udinga ukululama okusheshayo, i-LASIK ingaba yindlela engcono.
