PURPOSE
To perform microcoaxial phacosurgery of a black
cataract through a 2.2mm incision.
3
METHODS

• Phacoemulsification surgery is performed under
  peribulbar anaesthesia through a 2.2mm slimbal
  incision.
• Miniflare tip and ultrasleeve are used.
• Sodium hyaluronate Chondroitin Sulphate is the
  OVD used.

4

• Sculpting is done using longitudinal and
  torsional energy in combination.
• Posterior nuclear plate is sculpted but utmost
  care is taken not to penetrate the posterior
  capsule.
• Care is taken while cracking the leathery,
  extralarge and extrahard nucleus, so as to not to
  tear the post. capsule.

5

• Fragment removal is used using only torsional
  energy.
• Maximum AFR is kept at 45cc/min(linear) and max.
  vacuum at 400mmHg (linear).

6

• OVD is used to sandwich the nuclear fragments so
  as to prevent the endothelial damage as well as
  protect the posterior capsule.

7

• The wound remained at 2.2mm at the completion of
  the surgery.

8

• A foldable IOL is implanted.
• The eye was examined on the third post operative
  day.

RESULTS

• Phacoemulsification surgery is performed under
  peribulbar anaesthesia through a 2.2mm slimbal
  incision.
• An uncomplicated phacomulsification is completed
  through 2.2mm incision.
• The incision remains at 2.2mm at the end of the
  surgery.
• Using only torsional energy during fragment
  removal prevents clogging at the tip.
• Using comparatively higher AFR and vaccum during
  fragment removal reduces the energy consumption.
• The cornea remained clear on the third post
  operative day examination.

10
CONCLUSION

• Microcoaxial phacosurgery can be effectively
  done in a black cataract without any complication.
