Utyando lwe-PRK: kwenziwa njani, emva kokusebenza kunye neengxaki

Umxholo

• Lwenziwa njani utyando
• Njani ukuchacha kwixesha postoperative
• Umngcipheko wotyando lwe-PRK
• Umahluko phakathi kotyando lwePRK kunye neLasik

Utyando lwe-PRK luhlobo lotyando lwamehlo olusebenzayo olunceda ukulungisa iqondo leengxaki zombono ezinje nge-myopia, hyperopia okanye i-astigmatism, ngokutshintsha imilo ye-cornea usebenzisa i-laser elungisa i-curvature ye-cornea, ekwaziyo ukuphucula umbono .

Olu tyando lunezinto ezininzi ezifanayo notyando lweLasik, nangona kunjalo, amanyathelo athile enkqubo ahlukile kwindlela nganye, kwaye nangona olu tyando luvele ngaphambi kotyando lweLasik kwaye lunexesha elide lisebenza, lisasetyenziswa kwiimeko ezininzi, ngakumbi kubantu i-cornea encinci.

Ngaphandle kotyando olukhuselekileyo kunye nokuzisa iziphumo ezinkulu kumbono, kusenokwenzeka ukuba ube neengxaki kwithuba lasemva kokusebenza, njengosulelo, izilonda zesisu okanye utshintsho kumbono, umzekelo, kwaye ukunqande kubalulekile ukuthatha amanyathelo okhuseleko ukusebenzisa amathontsi wamehlo amiselweyo, ukulala nemigogo ekhethekileyo kunye nokuphepha ukuqubha kwiindawo zikawonke-wonke inyanga e-1.

Lwenziwa njani utyando

Utyando lwe-PRK lwenziwa ngaphandle kwe-anesthesia ngokubanzi kwaye, ke, umntu uphaphile lonke unyango. Nangona kunjalo, ukunciphisa iintlungu kunye nokuphazamiseka, amathontsi okubulala iintlungu asetyenziselwa ukuqaqamba iliso okwemizuzu embalwa ngaphambi kokuqala inkqubo.

Ukwenza utyando, ugqirha ubeka isixhobo ukugcina iliso livulekile kwaye asebenzise into enceda ukususa umaleko omncinanana nobonakalayo we-cornea. Emva koko, kusetyenziswa i-laser elawulwa yikhompyuter ethi ithumele ukukhanya okukhanya kwiso, ukunceda ukulungisa ukugoba kwe-cornea. Okwangoku kunokwenzeka ukuba uve ukonyuka okuncinci koxinzelelo kwiso, nangona kunjalo, kukuziva ngokukhawuleza kuba inkqubo ithatha malunga nemizuzu emi-5.

Okokugqibela, iilensi zonxibelelwano zisetyenziswe ngaphezulu kwamehlo ukubuyisela okwethutyana inwebu encinci ye-cornea esuswe kwiliso. Ezi lensi, ukongeza ekukhuseleni amehlo akho eluthulini, zinceda ukuthintela usulelo kunye nokubuyisa isantya.

Njani ukuchacha kwixesha postoperative

Emva kotyando, kuyinto eqhelekileyo ukuba ungonwabanga kwiliso, ngokuziva uthuli, ukutshisa kunye nokurhawuzelela, umzekelo, ukuthathwa njengesiqhelo kunye nesiphumo sokudumba kweliso, ukuphucula emva kweentsuku ezi-2 ukuya kwezi-4.

Ukukhusela iliso, ekupheleni kotyando, iilensi zonxibelelwano zibekwa ezisebenza njengempahla yokunxiba, ke ngoko kuyacetyiswa ukuba uthathe amanyathelo okhuseleko kwiintsuku zokuqala, njengokungathambisi amehlo, ukuphumla amehlo nokunxiba iiglasi zelanga ngaphandle.

Ukongeza, kwiiyure zokuqala ezingama-24 emva kotyando, kuyacetyiswa ukuba ukunqande ukuvula amehlo akho phantsi kweshawa, ungaseli utywala, ungabukeli umabonwakude okanye usebenzise ikhompyuter ukuba amehlo akho omile. Ezinye izilumkiso ngexesha lokubuyisela kwimeko yesiqhelo yile:

• Nxiba iigggies ezizodwa ukuze ulale, ixesha elinconyelwe ngugqirha wamehlo, ukunqanda ukukrwela okanye ukwenzakalisa amehlo akho xa ulele;
• Sebenzisa amayeza achaseneyo nokudumba okuchaziweyo, afana neIbuprofen, ukunciphisa iintlungu zentloko kunye nentlungu esweni;
• Emva kweeyure ezingama-24 zokuqala, kufuneka uhlambe intloko ngexesha lokuhlamba amehlo akho evaliwe;
• Ukuqhuba kufuneka kuqalwe kwakhona emva kokuba ugqirha eyibonisile;
• Ukwenziwa kwakhona kunokusetyenziswa kwakhona malunga neeveki ezi-2 emva kotyando, kwaye kufuneka ifakwe ngononophelo;
• Akufanele udade i-1 inyanga kwaye uphephe ukusebenzisa i-jacuzzis iiveki ezi-2;
• Akufanele uzame ukususa iilensi ezibekwe emehlweni akho ngexesha lotyando. Ezi lensi zisuswa ngugqirha malunga neveki enye emva kotyando.

Imisebenzi yemihla ngemihla inokuphinda iqale kancinci emva kweveki e-1, nangona kunjalo, abo banefuthe elikhulu, njengemidlalo kufuneka baphinde baqalise kuphela ngogqirha.

Umngcipheko wotyando lwe-PRK

Utyando lwe-PRK lukhuselekile kakhulu kwaye, ke, iingxaki zinqabile. Nangona kunjalo, enye yezona ngxaki zixhaphakileyo kukubonakala kwezikrelemnqa kwi-cornea, eyenza umbono ube mandundu kwaye wenze umfanekiso otyhafileyo. Le ngxaki, nangona inqabile, inokulungiswa ngokulula ngokusetyenziswa kwamaconsi e-corticosteroid.

Ukongeza, njengalo naluphi na utyando, kukho umngcipheko wosulelo kwaye, ke ngoko, kubaluleke kakhulu ukuba uhlale usisebenzisa i-antibiotic eye eye echazwe ngugqirha kwaye ukhathalele ucoceko lwamehlo kunye nezandla ngexesha lokubuyisela. Jonga ukuba zeziphi izinto ezisi-7 ezibalulekileyo zokukhusela umbono.

Umahluko phakathi kotyando lwePRK kunye neLasik

Umahluko ophambili phakathi kwezi ntlobo zimbini zoqhaqho ngamanyathelo okuqala obu buchule, kuba, ngelixa kuqhaqho lwe-PRK umaleko ocekeceke we-cornea uyasuswa ukuvumela ukudlula kwelaser, kuqhaqho lweLasik, kuvulwa indawo encinci kuphela (i-flap) kwinqanaba elingaphezulu kwe-cornea.

Ke, nangona baneziphumo ezifanayo, uqhaqho lwe-PRK luyacetyiswa kwabo bane-cornea ethe tyaba, kuba kobu buchule, akuyomfuneko ukuba usike ngokunzulu. Nangona kunjalo, njengoko umaleko obhityileyo we-cornea ususiwe, ukubuyela kade kuhamba ukuvumela olo luhlu lukhule ngokwemvelo.

Ukongeza, ngelixa iziphumo zoqhaqho zikhawuleza ukuvela eLasik, kwi-PRK isiphumo esilindelweyo singathatha ixesha elide ngenxa yamathuba amakhulu okunyanga okunyanzelekileyo. Jonga ezinye iinkcukacha malunga notyando lweLasik.
