Nyob rau hauv lub realm ntawm ophthalmic refractment refraction kev phais mob, lasers sculpt lub bartea nrog micron- nplai precision kom rov ua kom pom kev. Tsis tau, cov hluav taws xob hloov hluav taws xob no nqa tau cov kev pheej hmoo: Uncontrolled laser raug yuav ua rau muaj kev puas tsuaj ocular puas hauv milliseconds. Cov lus qhia no synthesizes synthesizes synthious kev pom zoo tshaj plaws (2025) ntawm laser kev phom sij thiab cov tswv yim tiv thaiv, tsom xam tshwj xeeb rauPolycarbonate (PC) -} Raws li cov khoom siv tsom iav{{0- Lub Ntiaj Teb Tus Qauv rau Kev Tiv Thaiv Kev Tiv Thaiv thiab Cov Neeg Mob. Los ntawm kev sib cais mechanisms, chaw ua haujlwm, peb tsom rau thauj tog rau nkoj kev nyab xeeb ntawm lub plawv ntawm lub plawv ua tau zoo tshaj plaws.
