The pseudoaccommodative cornea multifocal ablation with a center-distance pattern: a review

Alain Telandro. J Refract Surg. 2009 Jan.

Abstract

Purpose: To describe an excimer laser ablation architecture called the pseudoaccommodative cornea (PAC) that uses ocular aberrometry and aspheric ablation profiles to create a multifocal cornea.

Methods: A descriptive article outlining the theory of the PAC algorithm.

Results: The topographic changes induced by PAC produce corneal multifocality.

Conclusions: PAC-treated eyes have progressive concentric rings of center-distance and midperipheral-near power that enable functional vision at near, intermediate, and distance.
