ungenelelo Surgical mazenziwe kule Buffet ekhethekileyo ekuvumela ukuba ukuphumeza imisebenzi, kuquka abantu nenkqubo othile musculoskeletal. uqhaqho cataract lunokwenzeka kwaye ngoncedo lwe laser ultrasound. A ukususwa lens lwenziwa ngendlela beztravmaticheskim, oko kwenzelwa okuhlatywa encinane, nto leyo ayifuni sutures emva kotyando.

utyando cataract lwenziwa kusetyenziswa laser kwaye utsalo xa ilens lwancothulwa amandla laser. Kulo mzekelo, phezu komhlaba ilens zabanjwa vee ezimbini nkqo. Siqala kernel aqhekeke abe ziingceba ezine. Emva koko la malungu kutshatyalaliswa ngokulandelelana, aze emva koko aspirated okanye ukuqhuba yokuhlamba izandla kunye nococeko. Emva zomzimba zenza tunneled liqatywe kwenwebu kwaye ukutshintsha ngumongo lens. yonke yokusebenza iphela emva kwemizuzu elishumi elinesihlanu.
