DESCRIPTION
AUROBLUE is a vital dye, used in matured cataract surgery, which stains
the anterior capsule and fibrous tissue that enables the surgeon to
visualize the capsule clearly. AUROBLUE is a sterile preparation of
Trypan Blue 0.06% w/v in buffered solution.
INDICATIONS
Used as a capsule staining agent in cataract surgery
CONTRAINDICATION
AUROBLUE is contraindicated when a non hydrated (Dry state) hydrophilic
acrylic Intraocular lens (IOL) is planned to implant into eye, because the
dye may be absorbed by the IOL and get stained.
WARNINGS & PRECAUTIONS
- Always use separate tuberculin syringe and needle
for AUROBLUE (Trypan Blue) injection. (Avoid antibiotic used
syringe/needle since it crystallizes the Trypan Blue).
-
Do not use the product after expiry date.
- Do not use on children and pregnant
women.
- For single use only.
- Not for IV/ IM injection.
ADVERSE REACTIONS
- AUROBLUE is well tolerated following
intraocular injection into the anterior chamber of the eye during
cataract surgery.
- Mild postoperative inflammatory reactions may
occur in a very few cases.
- Extreme care must be taken while
using AUROBLUE on patients who are hypertensive to any of its
components.
- During animal experiments,
teratogenic and/or mutagenic effect has been reported after repeated
and/or at high dose intraperitoneal or intravenous injections with
Trypan Blue. Hence Trypan Blue should not be used in pregnant women.
- Following use of AUROBLUE the
discoloration of high water content hydrogen intraocular lenses (See
contraindications) and inadvertent staining of the posterior lens
capsule and vitreous face may occur. Staining of the posterior lens
capsule or staining of the vitreous face is generally self limited,
lasting up to one week.
STORAGE
Store between 2 C and 35 C.
SUPPLY
Available in sterile 1ml vial with pouch in pack of five.
TECHNIQUE
Before using AUROBLUE the first step is to inject air into the anterior
chamber using a 26 gauge needle in the area where the second site is
made. This prevents dilution of the dye. Then AUROBLUE is injected into
the anterior chamber using a tuberculin syringe between the air bubble
and the lens capsule. Use the bevel down of the needle and inject
AUROBLUE in a drop form, so that the whole capsule gets stained. If some
area is left unstained, inject one more drop in that area till it gets
stained. It is allowed for a minute to achieve complete staining of the
anterior capsule.
After staining viscoelastic solution is
injected into the anterior chamber. This will distend the eye so that
when you make a clear corneal incision, the eye will be tense and one
can make a good valve. Now use a straight rod to stabilise the eye with
the left hand and with the right hand make a clear corneal incision or
scleral incision. Inject viscoelastic solution inside the eye to remove
the air bubbles and the AUROBLUE. Then capsulorhexis can be done with a
needle or with a forceps. One can see the contrast between the capsule,
which has been stained and the cortex,which is not stained. The
capsulorhexis can be continued and completed. |
