Izindlela ezisetyenziselwa ukugcina umbono ziquka:
- magnetotherapy;
- i-electrostimulation;
- iyeza laser;

Ukusebenza ngezinga eliphezulu le-myopia
Indlela yodwa yokubuyisela ubuncwane obubonakalayo, kwaye ungayilungeleli nayiphi na imyopia, utyando.

- Ukutshintshelwa kwentsholongwane yecala. Le ndlela isetyenziselwa ukujongana nokungena kwi-diopters -20. Iqulethe ukususa i-lens ngokusebenzisa i-microcut kunye nokuyifakela nge-lens yokurhafisa yamandla afunayo.
- Ukufakelwa kwee-phakic lens. Isetyenziswe xa iliso lingalahlekelwa yindawo yokuhlala yokuhlala. Kule meko, i-lens ayisuswanga, kwaye i-lens ifakwe kwisithuba esingaphandle okanye esingaphandle kweso. Le ndlela isetyenziselwa i-myopia ukuya kwi-diopters -25.
