OcuSeal is a completely synthetic Ocular sealant specifically designed
and
engineered for ophthalmic surgery. It is a dendritic polymer formulated
of
polyethylene glycol. It is biocompatible, bioabsorbable non-immunogenic
microbial barrier. It effectively seals the cornea and aids ocular tissue
healing.
With the rapid advancement of ocular surgery many ophthalmologists have
sought a sealant which could speed up surgery time, eliminate the need
for
sutures and decrease the complication
and morbidity rates associated with
certain procedures.

OcuSeal Ocular Bandage from
HyperBranch Medical Technology.
The polymer is highly biocompatible,
transparent, and has a very low
profile, causing little or no
foreignbody sesation.
HyperBranch Medical Technology
Applications:
Cataract surgery- provides a water tight seal for all corneal
incisions. Completely
eliminates the need for sutures and the complications associated therewith
including astigmatism, inflammation, infection and patient discomfort.
Lasik surgery- effectively seals the corneal flap, prevents epithelial
in growth
and has very minimal interference with patient vision over the 2 day post
operative period.
PRK surgery- protects the corneal surface as an ocular bandage and eliminates
the need for the placement of a contact lens post operatively.
Ptyregium surgery- effective as an adjunct to sutures, with fewer sutures
required
and providing unparalleled patient comfort.
Corneal ulceration- OcuSeal is a fast, cost effective way of effectively
sealing stellate and linear corneal wounds eliminating the need for a
contact lenses providing patients with comfort.

 Ocuseal is a new liquid ocular
bandage, developed by Hyperbranch
Medical Technology, (Durham, North
Carolina), which helps seal and
protect corneal incisions against
mechanical stress and irritation in
postsurgical, posttraumatic and
nontraumatic conditions.
This unique ocular bandage consists
of a synthetic dendritic hydrogel that
is easily applied—via a special brush
applicator—directly onto the ocular
surface as a liquid. The hydrogel is
activated by mixing two separate components. Upon application to the
cornea, it crosslinks within 30 seconds to form a low-profile, smooth,
soft, and
transparent protective barrier film on the ocular surface.
It’s as easy as one, two, three… with mixing and application
in 30 seconds.
Leaking Clear Corneal Incisions
Since its introduction in the early 1990’s, the technique of creating
a “self-sealing” clear corneal incision has become the standard
of care, primarily because it eliminated the need to use sutures, reduced
the incidence of suture induced astigmatism and lowered the cost of cataract
surgery. Unfortunately, it is not always possible to achieve the “perfect”
clear corneal incision, and it is often time consuming to test the wound
for leakage and to rehydrate the corneal stroma. In fact, evidence is
mounting that this wound architecture is highly correlated with an alarming
increase in the incidence of endophthalmitis, potentially the most dreaded
consequence of your cataract surgery cases and certainly most devastating
to your patients. Recent studies reported in the literature are summarized
to conclude the following:
• Incidence of endophthalmitis reported recently at 0.3%(1,2,3)
is 3 to 15 times greater in clear corneal incisions vs. sceral tunnel
incisions.
• Clear corneal incision a major risk factor (3) for endophthalmitis
with a likelihood odds ratio of 7 for developing endophthalmitis following
phacoemulsification cataract extraction through a clear corneal incision.
