Inkoliso yethu inokuthatha ngokukhawuleza ukulungelelanisa iilensi zokudibanisa ukulungisa iingxaki zombono eziqhelekileyo. Nangona kunjalo, iilensi zokudibanisa nazo zisetyenziselwa ukuhambisa iimpawu zokuphilisa kubantu abanezifo zeso. I-lens zoqhagamshelwano zisetyenziselwa ukubonelela ibhendi yeentlobo zokuphucula ukuphulukisa nokunciphisa intlungu evela kwiimeko ezithile zomhlaba. Nangona kunjalo, izazinzulu zivelisa iilensi zamanxeba namhlanje eziqulethe imithi okanye izinto eziphilayo ukuze zibuyiselwe impilo.
I-lens entsha ye-medical lens, i-Prokera, isetyenziswe oogqirha bamehlo ukulungisa nokuphulukisa isifo somntu. Iprokera iyinkqubo equle i-lens yokudibanisa eyenziwe yinto ecacileyo, iguquguqukayo kwaye yakha isahlulo sembrane ye-amniotic.
Yintoni i membrane yamniotic?
Amunyuotic tissue ivela kwi-placenta. I-placenta yinyama enika ukutya nokukhusela umntwana osakhulayo ngexesha lokukhulelwa. Iqulethe nezicubu ezinika izixhobo zokuphilisa. Ama-amniotic tissue athatyathwa kwizilwanyana eziphilileyo, ezivumayo ezingenazo izifo ezixubileyo emva kokuhanjiswa kwecandelo leC. Izicubu zihlolwe ngokupheleleyo kwaye zihlolwe izifo.
Iprokera yenza ntoni?
Iprokera inikeza iimpawu zokukhusela kunye nokuphilisa ezenza izicubu zamehlo ziphuluze ngokukhawuleza, zivelise intlungu engaphantsi, inciphise ukonakala kunye nokunciphisa ukuvutha. Nangona beyazi ukuba kusebenza, usosayensi akaqondi ngokupheleleyo ukuba unika njani le mpahla yokuphilisa.
Ziziphi iimeko eziza kuProteka?
I-PROKERA isetyenziselwa ukuphatha oku kulandelayo:
- keratitis
- ukutshisa imichiza
- isifo somzimba esomileyo
- izihlandlo eziphindaphindiweyo
- izilonda
- ukuguquka okungapheliyo
- ukuxhamla kunye neentlungu
- kraatopathy
- zifo
Oogqirha bafaka njani iProteka?
Inkqubo yokungenisa ifanelekile.
Isigulane sihleli esihlalweni sokuhlolwa kwamehlo kunye nentloko yakhe kumqolo we-backrest. Ezinye izigulana ziyakuthi zikhishwe emva kwesihlalo. I-Lener i-lens yokuthintana nayo inkulu kunelo lensi yokuqhagamshelana ngokuqhelekileyo ngokokuba oogqirha bambi baya kufaka intambo yekhosidi ukuba ibambe iso. Kwizigulane ezininzi, iProkera iya kufakwa ngokufanayo kwi-lens yokuthintana rhoqo. Isigulane siza kujonga phantsi kwaye ugqirha uya kufaka i sixhobo ngaphantsi kwesikhophelo esiphezulu, shenxise isiqhekeza esingaphantsi uze ususe isangqa esezantsi ngaphantsi kwesikhumba sezantsi. Amakhonkco angaphandle kwe-lens ayancipha kwaye ngamanye amaxesha angabangela ukuphazamiseka. Ukuba i-lens ayinakulinganisekanga, ugqirha angasigcina ikhefu. I-lens ishiywe iliso kwiintsuku ezili-10, nangona ugqirha angakhetha ukuyikhupha kungekudala okanye iintsuku ezimbalwa emva koko. Ngokuxhomekeka kwimeko, isigulane sibonwa imihla ngemihla okanye malunga neveki.
Umsebenzi weProkera?
Prokera inikeza ukukhuselwa komatshini kwi-eyelidi nakwiimeko zangaphandle. Yintoni eyenza iProteka ibe bhetele kunokuba i-lens ye-bandage yokudibanisa yinto eqhelekileyo yinto evumela ukuba ubuso bamehlo baphilise ngokunciphisa izinto ezithile zokukhula kunye nemichiza ephambukayo enokubangela ukuvuvukala nokukhwabanisa.
Kwakhona kunciphisa ithuba lokusebenzisa imilambo yegazi engavamile. Ngaphezu koko, iPkera inikeza ezinye izakhiwo zokulwa ne-antibacterial ukunciphisa usulelo.
Ulungele iProteka?
I-Prokera yinkqubo yokuqhagamshelana nezokwelapha ezinokuthi zilungele kwi-cornea enezifo ezinokuguqulwa okungapheliyo xa unyango lwamayeza okanye unyango lwezonyango luhluleka. Kukhuselekile kwaye kuyasebenza kwaye izicubu zilawulwa yi-FDA. I-lens ekhethekileyo yoqhagamshelwano kufuneka idlule amanqanaba amanqanaba okulawula ngaphambi kokusetyenziswa ngugqirha wakho. Ininzi yomshuwalense yonyango kunye ne-Medicare ihlanganisa isixhobo kodwa ukugunyazwa kwangaphambili kuyadingeka kwiimeko ezininzi.
