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
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

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.
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:
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).
