Accommodative Hydrophobic Surface Lens
Description : (design
concept of Accomodative IOL)
Since the evolution of cataract surgery, the ultimate goal of
cataract surgeon has been to provide unaided, high quality vision
for distance, intermediate and near objects including every point in
between. Eyecryl Plus HSATF575 is an accommodative lens plus CTR
with a revolutionary design which is based on Hemholtz's theory of
accommodation and addresses the problem of pseudophakic presbyopia
fully and satisfactorily.
This IOL allows implantation through a standard
phacoemulsification incision of sub 2.6 mm. The six haptics design
with anterior vaulting allows the lens to move accommodate, to focus
on objects near, far and at all distances in between without any
hysterisis. The posteriorly vaulted haptics ensure minimum adhesion
to anterior subcapsular cells for a longer period to maintain
accommodation effect.

Advantages of Surface modified IOLs:
Surface which is permanent in
nature and technology that has proven its effectiveness in many
implantable medical devices
Higher contact angle increases
hydrophobicitySmooth lens surface prevents bacterial adhesion
Lower surface energy inhibits cell
growth and cell adherence thus postponing the secondary cataract
Resistance to silicon oil
adherence
Reduced inflammatory cell response
Optical Purity-no vacuoles
High Biocompatibility
Facilitates placement of the lens
and reduces trauma to the patient by allowing for a smaller incision
during surgery
Implantation without substantial
risk of corneal endothelial cell damage
Insensitive to atmospheric
temperature changes as compared to hydrophobic IOLs
Less attractive to airborn
particles in operational field
Cost effective.
