Microwave Technology For Reshaping OF

Cornea

Sh.Hanjani , M.DOphthalmologist

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 : 18-24

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
