EYECRYL PLUS CLEAR

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.

FEATURES

  • Aspheric Optic Surface: Unlike traditional spherical intraocular lenses (IOLs) that can induce positive spherical aberrations, Eyecryl Plus Clear is engineered with an aspheric optic surface. This design maintains a uniform diopter from the central optical zone to the edge, improving contrast sensitivity and reducing the occurrence of visual aberrations.
  • 360° Square Edge: The 360° square edge architecture of Eyecryl Plus Clear is strategically designed to mitigate posterior capsule opacification. By inhibiting lens epithelial cell migration and proliferation, this feature minimizes the risk of secondary cataracts, ensuring prolonged visual clarity for patients post-cataract surgery.
  • Increased Hydrophobicity: Through surface modification, Eyecryl Plus Clear achieves heightened hydrophobicity while retaining the inherent biocompatibility of hydrophilic acrylic material. This innovation renders the lens less susceptible to cell attachment and growth, thereby significantly reducing the likelihood of secondary cataract formation and preserving long-term visual acuity.
  • Exact Refractive Value: Precision is paramount in cataract surgery outcomes, which is why Eyecryl Plus Clear incorporates the exact refractive value on its packaging. This ensures accurate visual correction for patients, minimizing the potential for refractive errors and optimizing postoperative vision.
  • 5° Angulation: Eyecryl Plus Clear features a 5° angulation design, facilitating optimal contact with the posterior capsule upon implantation. This enhances intraocular lens stability within the eye, minimizing the risk of decentration or dislocation and promoting reliable long-term visual performance.
  • UV Blocking Material: In recognition of the harmful effects of ultraviolet (UV) radiation on ocular health, Eyecryl Plus Clear integrates UV blocking material into its composition. This additional safeguard provides comprehensive protection against UV-induced ocular pathologies, ensuring the ongoing well-being of patients’ eyes.

INGREDIENTS

The primary ingredient of Eyecryl Plus Clear is a hydrophilic acrylic polymer, renowned for its biocompatibility and optical clarity. This material undergoes meticulous surface modification to enhance its hydrophobic properties while preserving its structural integrity and optical performance.

OPERATIONS

Eyecryl Plus Clear is indispensable in ophthalmic surgeries, particularly during cataract extraction procedures. Following the removal of the clouded crystalline lens, Eyecryl Plus Clear is implanted into the capsular bag in the posterior chamber of the eye, effectively restoring visual function and clarity in patients with aphakia secondary to cataracts.

ADVANTAGES

  • Optimized Visual Clarity: By incorporating an aspheric optic surface, Eyecryl Plus Clear enhances visual clarity and contrast sensitivity, enabling patients to experience sharper and more vivid vision following cataract surgery. The innovative 360° square edge design and surface modification technology of Eyecryl Plus Clear effectively deter lens epithelial cell proliferation, significantly reducing the incidence of posterior capsule opacification and secondary cataract formation.
  • Enhanced Surgical Outcomes: With its precise refractive value printed on the packaging, Eyecryl Plus Clear ensures accurate visual correction, minimizing the likelihood of postoperative refractive errors and optimizing overall surgical outcomes for patients.
  • Long-Term Stability: The 5° angulation feature of Eyecryl Plus Clear promotes secure fixation within the eye, enhancing intraocular lens stability and minimizing the risk of displacement or misalignment over time, thereby prolonging visual rehabilitation and patient satisfaction.
  • Comprehensive Eye Protection: Incorporating UV blocking material, Eyecryl Plus Clear provides comprehensive protection against harmful UV radiation, safeguarding the ocular health of patients and reducing the risk of UV-induced ocular pathologies, such as cataracts and macular degeneration.

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).
