PHACOEMULSIFICATION WITH A BEVEL-DOWN PHACO TIP - PHACO-DRILL

We present a technique for in situ lens nucleus emulsification using l ow phaco power and high vacuum, a continuous curvilinear capsulorhexis , and hydrodelineation. Emulsification is done with the phaco tip slan ted down 30 or 45 degrees. Cutting and aspiration do not cause an unde sirable energy loss. This technique can be combined with the nuclear c hopping or divide and conquer methods because of its ability to drill and hold the nucleus. Posterior capsular rupture is prevented because the separated epinucleus acts as a barrier between the nucleus and the cortex. The low power used minimizes the energy transfer to the corne al endothelium. This technique is particularly useful in eyes with bru nescent cataract.
