A systematic and sophisticated 3-step solution that adds durability to corneas weakened by surgery.
Application of Riboflavin
to the corneal stroma after vision correction surgery.
Rinsing the corneal surface
with sterile saline.
Irradiation with UVA light
for 90 seconds to achieve strengthening.
Heals damaged corneal tissue and prevents
side effects using Riboflavin and UVA light.
After absorbing Riboflavin into the corneal stroma (weakened by laser ablation) and
applying UV light, the bonding strength of the
collagen proteins forming the cornea is maximized.
This increases the biomechanical strength of the cornea by over 150%,
fundamentally blocking long-term side effects such as
corneal ectasia (keratoconus) and myopic regression.
The most important factor in corneal strengthening is the
technology to deliver precise energy in a short time.
Avedro Xtra significantly shortens surgery time
compared to conventional methods, minimizing corneal
dehydration and the patient's dry eye burden.
The original corneal strengthening device widely used
by ophthalmologists worldwide,
boasting safety backed by overwhelming clinical data.
An error-free, uniform UV irradiation system that induces
consistent bonding throughout the cornea to maximize the strengthening effect.
Innovative technology drastically shortens UV irradiation time,
improving patient comfort and minimizing corneal damage.
