ABSTRACT
The article presents the aberrometry results of a new intraocular lens (IOL) model with variable refractive surface of own design. By changing the pressure of silicone oil inside the artificial lens three levels of refractive power were achieved: 17.5D; 20.0D; 22.0D. The quality of the experimental optical system is comparable to that of a human eye after in vivo implantation of a ReSTOR multifocal IOL. Accommodating IOLs with refractive power varying within 4.5D are capable of maintaining the quality of retinal image, thus, ensuring high visual acuity.

There was made an aberrometry of new IOL with changeable refractive surface. Different power of silicon oil inside the lens become changes in it refractive power. So, in this way we made three types of IOL refractive power: 17,5 D; 20 D; 22 D. The quality of experimental optical system may be comparative with optical system that made by ReSTOR IOL implantation in human eye. HOA and LOA, that generated by the new IOL, had no or small influence to the quality of optical system.
