Corneal Topography

Txheej txheem cej luam

Corneal topography yog ib qho kev kuaj pom zoo tshaj plaws uas siv los qhia txog qhov curvature thiab cov duab ntawm lub cornea, pob tshab ntawm lub qhov muag. Cov txheej txheem uas tsis yog-invasive no tsim cov ncauj lus kom ntxaws 3D sawv cev ntawm lub pob kws, pab kws kho qhov muag kuaj xyuas thiab tswj ntau qhov muag qhov muag. Nws ua lub luag haujlwm tseem ceeb hauv kev ntsuam xyuas cov neeg mob rau kev phais mob xws li LASIK, kuaj pom qhov mob ntawm lub pob txha, thiab ua kom haum rau cov lo ntsiab muag kom raug.

Corneal Topography yog dab tsi?

Corneal topography, tseem hu ua videokeratography, siv computerized systems los soj ntsuam lub cornea's nto. Qhov kev ntsuam xyuas tsim ib daim ntawv qhia xim-coded qhia qhov txawv ntawm pob txha curvature thiab nce.

• Cov duab ntxaws: Maps lub corneal nto nrog high precision.
• Tsis-Invasive: Tsis muaj kev sib cuag nrog lub qhov muag, ua rau nws xis nyob rau cov neeg mob.
• Real-Time Analysis: Muab cov txiaj ntsig tam sim ntawd los qhia cov phiaj xwm kho mob.

Vim li cas Corneal Topography tseem ceeb?
