Dear Editor,
We would like to introduce a simple technique for the
bimanual irrigaton and aspiraton (I/A) of ophthalmic vis-
cosurgical device (OVD) and cortcal material during cataract
surgery.
Iris prolapse occurs when the forces pulling on the iris to-
ward the wound exceed the ability of the iris’ tone to main-
tain the positon of the iris in the anterior chamber [1].
Anterior wound placement should help to prevent iris
prolapse. Minimizing the irrigaton velocity, and hence the
fuid outlow velocity should also help to prevent intraoper-
atve prolapse [2].
Many surgeons prefer not to place the irrigaton/aspira-
ton (I/A) tp behind the optc during removal of an ophthal-
mic viscosurgical device (OVD) for fear of inducing a posterior
capsule rupture [3].
We had been using irrigaton tp to push IOL optc side-
ways and irrigate retrolentcular space to ease removal of
OVD via aspiratng cannula. We have observed that the in-
tracapsular irrigaton maintained the intraoperatve positon
of the iris with adequate formaton of the capsular bag and
anterior chamber even during removal of the OVD from the
anterior chamber. Then we have decided to use capsular bag
irrigaton during cortex removal as well. Iris prolapse was
seen to occur less frequently.
Afer phacoemulsifcaton is completed, the irrigaton can-
nula is directed into the capsular bag to achive irrigaton in
the capsular bag. In our technique irrigaton tp is introduced
into the capsular bag without a stop in the anterior chamber
while the aspiraton tp is held just in the tunnel of the other
side port occluding it and preventng egress of fuid from the
anterior chamber.
While traversing the anterior chamber, the infow is ob-
served to cause some futer of the iris and a slight forward
movement of the iris, but afer positoning the irrigaton tp in
the capsular bag the iris is seen to move backward and stop
futering. Being placed in the capsular bag and the directon
of egressing fuid towards the lens equator, the irrigaton
cannula provides excellent iris stability and positoning, and

it also keeps the anterior chamber and capsular bag well dis-
tended for easy removal of cortex via the aspiraton tp insert-
ed through the other side port.
Afer complete cortcal cleanup is accomplished, OVD is
used to fll the anterior chamber and the capsular bag. IOL is
implanted as usual. Then the irrigaiton tp is placed in the cap-
sular bag below the level of anterior capsule while the anteri-
or chamber is stll flled with the OVD and before the IOL has
been centered. The aspiraton port is placed in the capsular
bag facing the cornea, and is positoned behind the IOL optc
with the IOL stll slightly decentered.
Then the OVD is removed from the anterior chamber
while the irrigaton tp is stll kept in the capsular bag.
By using this technique we should have reduced the veloc-
ity of fuid fowing in the anterior chamber. By directng irri-
gaton fow into the capsular bag we should have the chance
for beter endothelial protecton otherwise irrigaton soluton
turbulence in the anterior chamber could cause more endo-
thelial damage [4].
We found this technique to be safe and efectve in re-
ducing the frequency of iris prolapse during bimanual I/A.
The other advantages are increased anterior chamber depth,
pupillary dilaton maintenance during I/A, and well-distended
capsular bag helping in the avoidance of accidental posterior
capsule capture and rent.
