The Blue Pearl - Safe Technique for Staining the Capsule

  Channels: Cataract Surgery | Posted 10/31/2013

The technique essentially involves injecting trypan blue under viscoelastic with a little modification of the steps and the cannula used. I use a modification of the Fogla air injection cannula used for creating a big bubble during DALK. This may be called the ‘Bhattacharjee cannula’ (Joja Surgicals, Kolkata, India). The 27 G cannula has a blunt and blind tip, anterior vaulted shaft and 2 bottom irrigating ports. Trypan blue is injected under the viscoelastic on to the anterior capsule through the bottom irrigating ports. The cannula is moved around to paint the dye on the capsule. The blunt tip and vaulted shaft ensure absolute safety of the capsule even with a hypermature intumescent cataract. The blind tip and bottom ports ensure that the dye stains only the visible anterior capsule and no dye migrates into the viscoelastic. The viscoelastic may be topped up to ensure better contact of the dye and wash away excess dye too. After waiting for a minute we can proceed with capsulorhexis under the viscoelastic. The staining of the capsule may be a bit patchy but is more than adequate to perform a safe capsulorhexis.
