<prompt> Fingqa isihloko: Uma wake wafuna ukuba nombono oqinile kaDaniel Craig noma ukubukeka okunothando kuka-Angelina Jolie, ukwelashwa okusha kwe-laser kungaba yimpendulo. Inkampani yaseCalifornia ithi inethemba lokunikeza inqubo yezokwelapha ebiza amaRandi angu-2 000 engashintsha noma imuphi umbala wamehlo ube luhlaza okwesibhakabhaka, unomphela. Le nqubo, okwamanje evivinywa emitholampilo, isebenza ngokusebenzisa okuthile okwaziwa ngokuthiamangqamuzana okuhlanza ukuze kugaywe futhi kususwe umbala ebusweni be - iris. Skrolela phansi ukuze ubone ividiyo. Le nqubo, okwamanje isesilingweni somtholampilo, isebenza ngokusebenzisa okuthile okwaziwa ngokuthi amaseli okuhlanza ukugaya nokususa i-pigment ebusweni be-iris. Le nqubo isebenzisa i-laser eqondiswa ikhompyutha, enamandla aphansi kuyi-iris ukuze iphazamise i-pigment ensundu. Imvamisa ethile ye-laser idlula kuyi-cornea esobala yeso, ngaphambi kokuba imuncwe ngokukhetha yi-pigment emnyama emboza i-iris. Lokhu kubangela ukuba umzimbauqalise inqubo engokwemvelo futhi eqhubekayo yokususa izicubu. Lapho nje izicubu sezisusiwe, amehlo aluhlaza okwesibhakabhaka avulekile, kuchaza le ngosi. Ngokukhipha lo mbala, ukukhanya kungangena ezintweni ezincane esweni. Lapho ukukhanya kuhlakazeka, kubuyisela emuva kuphela ubude bamaza obufushane kakhulu, obubonakala buluhlaza okwesibhakabhaka. UDkt. Gregg Homer, usihlalo nesikhulu sesayensi eStrōma Medical, wathi: Ngaphansi kwawo wonke amehlo ansundu kukhona amehlo aluhlaza okwesibhakabhaka. Umehluko kuphela phakathi kwazo uwukuthi iso elinsundu linengqimba encane ye-pigment emboza i-iris eluhlaza okwesibhakabhaka. Le nqubo isebenzisa i-laser eqondiswa ikhompyutha, enamandla aphansi kuyi-iris ukuze iphazamise i-pigment ensundu. Imvamisa ethile ye-laser idlula kuyi-cornea esobala yeso, ngaphambi kokuba imuncwe ngokukhetha yi-pigment emnyama emboza i-iris. Lokhu kubangela ukuba umzimbauqalise inqubo engokwemvelo futhi eqhubekayo yokususa izicubu. Lapho nje izicubu sezisusiwe, kubonakala iso lomuntu eliluhlaza okwesibhakabhaka, kuchaza ingosi yalo. Ngokususa lo mbala, ukukhanya kungenza...  <response>: I-laser enamandla aphansi isetshenziswa kuyi-iris ukuze iphazamise i-pigment ensundu. Lokhu kubangela ukuba umzimba ususeamangqamuzana okuhlanzaukuze asuse imibala emnyama. Le nqubo ithatha imizuzwana engu-30, futhi ngemva kwamasonto amabili amehlo ayoba luhlaza okwesibhakabhaka. Iziguli ezingu-17 eMexico nezingu-20 eCosta Rica ziye zelashwa. Le nqubo, esekuhlolweni kwezokwelapha, iphakamise ukukhathazeka ngokuphepha.
