Monofocal Hydrophilic Acrylic Aspheric Foldable Intraocular Lens
Eyecryl Plus hydrophilic IOLs are intended to be implanted into the capsular bag in the posterior chamber of the eye for the visual correction of aphakia secondary to the removal of the crystalline lens in the adult patients with cataracts.
Aspheric optic surface
360 ° square edge
Increased hydrophobicity because of surface modification hydrophilic IOL
Less attractive to cell attachments & cell growth
Surface modification helps in preventing the secondary cataract
Exact refractive value of the IOL is printed along with diopter on the box
5° angulation ensures better contact with posterior capsule

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.
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).
