EYECRYL PLUS CLEAR

Clear Aspheric Foldable IOLs

Surface Modified Hydrophilic Acrylic Foldable IOLs with Delivery System

Eyecryl Plus Clear IOLs are aberration free IOLs with aspheric optic. The aberration free design provides good performance and vision even in case of zonular weakness, decentered pupils and tilting of lens. Eyecryl Plus Clear IOLs have been tested for +0.5 mm of decentration and 5° of tilting. The visual function in all lighting conditions improves drastically.

FEATURES

Aberration free optic for better depth of visual field

360 ° square edge with Hydrophobic Surface to postpone PCO

Enhances contrast sensitivity, sharpness and clarity in all lighting conditions

Optical purity, no vacuoles

Smooth lens surface reduces bacterial adhesion and inflammatory cell response

Higher contact angle increases hydrophobicity

Lower surface energy inhibits cell growth & cell adherence thus postponing the PCO

Resistance to silicon oil adherence

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 airborne particles in operational field

Exact refractive value of the IOL is printed along with diopter on the box

Universally accepted haptic design which postpones PCO

ASPHERCITY

Conventional spherical IOLs have positive spherical aberrations resulting in decreased contrast sensitivity.

As shown in the diagrams below, in case of Eyecryl Plus Clear IOLs, the diopter remains uniform from central optical zone to the optical edge, whereas in case of conventional spherical IOL, diopter shift is evident outside the central optical zone of 3.0 mm.

HYDROPHOBIC SURFACE MODIFICATION

Surface modification offers a hydrophilic lens with surface properties similar to hydrophobic lens without changing the bulk properties of the IOL material.

The idea behind surface modification of Hydrophilic IOL is to make it more hydrophobic & render it less attractive to cell attachment and cell growth.

Hydrophilic acrylic material has a proven clinical history and acceptability within ophthalmic segment. We are providing a major advantage to this material by providing a permanent hydrophilic acrylic polymer.

CONTACT ANGLE

Hydrophobicity can be monitored by water contact angle measurement sessile drop method (contact angle increases in case of surface modified IOLs). Contact angle prevails about 35° – 45° in case of conventional hydrophilic IOL, which increases up to 75° – 85° in case of surface modified hydrophobic IOL. Pictures of measuring contact angle are shown below:

REFRACTION VALUE

The Refraction value mentioned on the lens label is the actual value of measurement after all the manufacturing processes (including surface modification of hydrophilic lenses).
