The “Eiffel tower technique” is a synonym for the well-known Y-groove method of sculpting a nucleus i when avoiding hydrodissection, such as in cases of polar cataracts or a compromised posterior capsule after intra-vitreal injection. Since the nucleus won’t free-spin, you must create a specific sculpting pattern to facilitate division. Sculpt a deep central stem toward 6 o’clock, then branch two arms toward 10 and 2 o’clock. Once the grooves are deep enough, use a second instrument to provide lateral counter-pressure against the phaco tip. This splits the nucleus into three distinct segments. These smaller pieces can then be safely emulsified and removed without requiring the initial fluid wave.
