Suction ring for microkeratomes
This suction ring is composed of a ring-shaped body ( 1 ) with an incarcerated, bevelled front opening ( 2 ), with an anterolateral cannula ( 4 ) for connection to a vacuum pump and a dovetail guide ( 7 ) on which the microkeratome cutting blade moves. The lateral wall of the body ( 1 ) has a tapere...

| Zusammenfassung: | This suction ring is composed of a ring-shaped body (
1
) with an incarcerated, bevelled front opening (
2
), with an anterolateral cannula (
4
) for connection to a vacuum pump and a dovetail guide (
7
) on which the microkeratome cutting blade moves. The lateral wall of the body (
1
) has a tapered truncated conical configuration, diverging backwards for adaptation to the eyeball, in order to increase the suction capacity to the eye. The front area has a wider stepped perimeter (
6
), which together with a bulge (
8
) on the outer edge and corresponding to the tips of the guide (
7
), increases the effective length of the latter, allowing better fixation of the cutting blade. |
