1563: phaco incision between RK cuts

Radial keratotomy (RK) makes cataract surgery far more challenging. The IOL power calculations are dramatically affected and during surgery we have to be careful to avoid the old RK incisions. Remember that these RK incisions are at least 90% depth which means there will be only about 50 microns of untouched corneal tissue holding the eye together. That’s thinner than a strand of hair. In this case, I am placing the phaco incision between two RK cuts without intersecting them. But wouldn’t it make more sense to use a smaller phaco incision such as 2.2 mm or 2.4 mm in width? Why would I choose to use the 2.75 mm-wide diamond keratome to make the phaco incision? Think about it before you watch the video for my answer.
