Umbuzo: Ingabe ukuhlinzwa kwe-LASEK kuyinto efanayo nokuhlinzwa kwe-LASIK? Ngingazi kanjani ukuthi iyiphi inqubo engcono kimi?
Impendulo: I- LASEK ne- LASIK yizinqubo ezimbili ezifanayo zokulungiswa kombono ezinemibono ebalulekile.
Uma utshelwe ukuthi awuyena ozobhapathizwa kahle we-LASIK, ungase ujabule ukufunda ukuthi i-LASEK ingaba nenzuzo kuwe. Ngenkathi izinqubo ze-LASEK ne-LASIK ziveza imiphumela efanayo, kunezinzuzo nezinkinga zombili.
Kuyini i-LASEK?
I-Laser Epithelial Keratomileusis, noma i-LASEK, inqubo yokulungiswa kombukiso ifana kakhulu ne-LASIK. Kunjenge-LASIK, i-LASEK isetshenziselwa ukulungiswa kokubona okuncane , ukubhekwa phambili , i- astigmatism ne- presbyopia .
Ngenkathi i-LASIK isebenzisa i-laser ukuze ivuselele kabusha i- cornea yakho, ngokusika ngaphakathi ekungeneni kwangaphandle kwe-eyeball, i-LASEK inquma kuphela njenge-epithelium (ungqimba lwangaphandle lwe-cornea).
Ingxenye yokuqala yenqubo ye-LASEK ihluke kakhulu kunqubo ye-LASIK. Ngesikhathi se-LASIK, ukumboza okunamandla kwezicubu ezinama-corneal kunqunywa nge-microkeratome blade noma i-laser ehlukile. Nge-LASEK, udokotela ohlinzayo wenza ukusika okuhle, okungajulile engxenyeni engenhla yangaphandle ye-cornea (ungqimba we-epithelial). Udokotela ohlinzayo usebenza isisombululo sezokwephuza cishe imizuzwana engama-30, esenza ukukhulula uhlaka lwama-epithelial, olwenza lukwazi ukuphakanyiswa futhi lufakwe eceleni. I-laser isetjenziswa ekutheni umthamo ophakathi kwamanzi we-cornea (stroma).
Udokotela ohlinzayo bese ephoqa ngobumnene isendlalelo se-epithelial phansi kwesibhado esisha.
Izinzuzo ze-LASEK
Kokubili i-LASEK ne-LASIK ngokuvamile iphephile futhi isebenza kahle, kodwa iziguli zaseLasek zibika imiphumela engcono kakhulu yesikhathi eside. Nakuba ukuphola kokuqala kunesikhathi eside kuneLASIK, iziguli ze-LASEK zibika ukungathandeki okuncane kokuthunyelwa komsebenzi.
Kubuye kube nomngcipheko wokunciphisa ukutheleleka nokunciphisa ukuqhuma komsindo ngemuva kweLASEK.
Ngenqubo ye-LASEK, akukho ukukhathazeka ngokuthi kungenzeka ukusika iziphazamiso ezingavamile njenge-LASIK. Abanye abantu ababhekene neLasek banokuphumula okusheshayo kokuzwa kwe-nerve ku-cornea. Ngenxa yokuthi izinzwa ze-corneal zidlala indima ethile endleleni yokuphendula eyenza amehlo akho agciniwe, kubonakala sengathi kunesisindo esincane seso elomile , isikhalazo esivamile ngemva kokuhlinzeka nge-LASIK.
Izinkinga ze-LASEK
Ukungalungi okuyinhloko kwe-LASEK yisikhathi sokuphulukisa kancane. Nakuba ngokuvamile elula, abanye abantu babonakala bezwa ubuhlungu obuncane kunelabo abaye bathola i-LASIK. Odokotela abaningi abahlinzayo bayodinga ukuthi ugqoke i- lens yokuxhumana ye-bandage ngezinsuku zokuqala ezingu-4 kuya kwezingu-5 emva kwenqubo ye-LASEK.
Ngubani okufanele abe ne-LASEK?
Uma udokotela wakho wezinyathelo enqume ukuthi awuyena omele ukhetho lwe-LASIK, i-LASEK ingaba kungenzeka kuwe. Njengoba ukuhlinzwa kwe-LASIK kuhilela ukusika ngaphakathi kwezicubu ze-cornea, i-LASEK iyinhle yokukhetha abantu abane-corneas encane, ephathekayo noma engavamile.
