Purpose: To compare postoperative best distance visual acuity (VA), contrast sensitivity and colour perception with the blue light-filtering AcrySof® Natural (SN60AT) and AcrySof® single-piece (SA60AT) intraocular lenses (IOLs). Methods: This was a prospective, randomized, comparative, interventional study comparing postoperative performance between the SN60 and SA60 IOLs. There were nine patients (nine eyes) in the SN60 group and 10 patients (10 eyes) in the SA60 group. All patients were operated using phacoemulsification. Postoperative VA (Snellen chart), contrast sensitivity (Pelli-Robson contrast sensitivity chart) and colour perception (Farnsworth-Munsell D-15 panel test) were measured at 1, 3 and 6 months postoperatively. Results: Postoperative best corrected VA after 6 months was 20/20 or better in 89% of SN60 eyes and 100% of SA60 eyes. Postoperative contrast sensitivity scores improved significantly in both groups under both photopic and mesopic conditions. There were no statistically significant differences in contrast sensitivity scores between the SN60 and SA60 groups at any of the postoperative evaluation time-points. Postoperative colour perception improved significantly in both the SN60 and SA60 groups, and there were no statistically significant differences in colour perception performance between the two groups. Conclusion: The blue light-filtering AcrySof® Natural (SN60) IOL has postoperative visual performance comparable with that of the AcrySof® single-piece (SA60) IOL.
