Prospectively randomized trial comparing the pseudoaccommodation of the AMO ARRAY multifocal lens and a monofocal lens

ABSTRACT A prospective trial was set up to compare pseudoaccommodation. Fifty patients were randomized into two groups. Group 1 comprised 25 patients who had a monofocal implant and a postoperative refractive aim of ‐0.3 to ‐1.3 diopter (D) spherical equivalent and an astigmatic component between 1.0 and 1.75 D cylinder. Group 2 comprised 25 patients who had a new multizone refraction style multifocal implant and a postoperative refractive aim of ‐0.5 to +0.5 D spherical equivalent and an astigmatic component of less than 1.0 D cylinder. Eighty percent of postoperative refractions in Group 1 and 88% in Group 2 were within 0.5 D either side of the refractive aim. Forty‐eight percent of Group 1 and 72% of Group 2 could see both 20/40 and J3 unaided. Four percent of Group 1 and 84% of Group 2 could read J2 with the distance correction. Sixteen percent of Group 1 and 48% of Group 2 could read J2 at 25 cm unaided (P = .03). Sixty‐four percent of Group 1 and 88% of Group 2 stated they could manage daily activities without glasses. However, 88% of Group 1 and 52% of Group 2 requested reading glasses to improve clarity of the smallest print.
