Abstract Details:



Purpose:

To investigate the chemical and physical changes in intraocular lens which are caused by the exposure of the acrylic material to the femtosecond laser.

Setting:

-

Methods:

The acrylic material was tested by a number of different methodologies, like e.g. CARSmicroscopy, to determine the nature of the changes created in the material by the exposure to the femtosecond laser.

Results:

The polar bonds within the acrylic material are altered such that the material absorbs additional water without creating residuals

Conclusions:

The hydrophilicity based refractive index change is safe to use in connection with implanted intraocular lense FINANCIAL DISCLOSURE: NONE
