Refractive Index Shaping: In Vivo Optimization of an Implanted Intraocular Lens (IOL)

Cataract surgeons are in constant pursuit to achieve optimal visual outcomes for their patients. Therefore, numerous technologies and techniques have emerged, most of which are designed to assist the surgeon preoperatively and intraoperatively. The in vivo modification is achieved by creating a lens within an existing IOL using a femtosecond laser. The lens within the lens is created by altering the hydrophilicity of an existing and standard IOL in certain designated areas. The changes created by the perfect lens technology alter the IOL’s refractive outcome and enable the surgeon to create the patient’s desired vision in a simple postoperative in-office procedure.
