LA LON
LA LON is a medium viscosity Sodium Hyaluronate based ophthalmic viscoelastic solution, designed for
routine cataract surgery. The Sodium Hyaluronate is derived from bacterial fermentation using a soy
peptone base, eliminating the need for materials of animal origin – which has become an issue lately.
LA LON is one of the most elastic materials produced using this source, with three characteristic
viscosities in three very important shear rate regions:
 The zero shear rate viscosity is responsible for the maintenance of space in the anterior chamber and
allows the manipulation of tissues during the operation without escaping trough the incision.
 The surgical shear rate viscosity determines the resistance to the instruments and implant during
intraocular procedures. It has to provide free movement for the instruments and an easy entry for
the implant into the inflated capsular bag.
 The injection shear rate viscosity causes the resistance when expressing LA LON trough a cannula.
The viscosity and elasticity range of LA LON have been selected to provide the highest possible zero shear
viscosity, while allowing unrestricted manipulation during surgery and still enabling the use of a thin, 27
gauge cannula for expression. These parameters have been fine tuned using small changes, based on
feedback from our specialists and customers worldwide.

Due to the bacterial fermentation and purification method, the residual protein
content of LA LON is so low, that refrigeration is not necessary to keep it safe for
intraocular use. Exposure to higher temperatures is known to break the long
molecular chains of Sodium Hyaluronate, leading to loss of viscosity. Therefore it
is recommended to store LA LON between +2 and +25 degrees Celsius, away
from light.
Also available in 10Pack
Every production lot is must pass several tests before being released. Among them are tests for viscosity
PH and endotoxin content. To ensure sterility, four separate test methods are applied simultaneously. A
100% final inspection ensures the quality of each individual unit.
* LA LON and LA GEL are manufactured at LA LABS in California. They are not relabeled versions of third party import products.
