Microwave for reshaping of cornea - Microwave technology uses since 15 years. - Currently in initial testing. - Is known as keraflex. - Single low energy microwave pulse lasting less than one second. - Energy applied in an annular pattern to corneal mid-periphery. - Single pulse raises the temp of stroma to 65° in the upper 150µ of stroma. - Evaporative cooling technique protect epithelium and bowman’s membrane.
- Shrinkage of collagen applies tensile stress to the central cornea causes flattening and reduction of myopia. - Refractive results depends to depth and diameter of the induced collagen. - More peripherally and deeper stromal tensioning causes steepening the cornea for correct hyperopia.
Total treatment time is about 2 seconds No pain Transient superficial haze is lost within minutes First day post OP seems noting done. Keraflex corrections lifespan : months, may extend with CCL Keraflex KXL for keratoconus. induced refractive effect as well as stabilize the KC
The protruding KC cone seen here is substantially de-centered and has a K reading of 52.7 diopters Keraflex effected an 8.1 diopter reduction in the cone and a more prolate shaped cornea
