Comparative Evaluation of Three Advanced IOLs

Three unused IOLs were tested: AcrySof IQ SN60WF (Alcon Laboratories Inc., Forth Worth, TX), monofocal; AcrySof IQ PanOptix TFNT00 (Alcon Laboratories Inc.), trifocal; and Symfony ZXR00 (Abbott Medical Optics Inc., Nieuwegein, the Netherlands), bifocal with extended depth of focus. Their main characteristics are summarized in the Table. The narrow-angle PSF and the modulation transfer function of these IOLs have been already evaluated in vitro.¹¹ (link)^–¹³ (link) In addition, their impact on the quality of vision has been clinically studied through the visual acuity and contrast sensitivity, as well as the incidence rate of photic phenomena (e.g., halos, flashes, starbursts, and glare).¹⁴ (link)^–¹⁶ (link) The three IOLs were taken from random batches.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
