Analysis and Comparison of the Defocus Curve of the Most Used Premium Intraocular Trifocal Lenses in Brazil: A Systematic Literature Review

This research analyzed and compared the DeFocus curve of the most widely used premium intraocular lenses (IOLs) in Brazil (At Lisa, Zeiss; Finevision, BVI; Gemetric, Hoya; Panoptix, Alcon and Synergy, Johnson), evaluating their variability, clarity between trifocal designs and effectiveness, as well as side effects and patient satisfaction. The systematic review included 46 articles (2010-2024) available in scientific databases. The analyses revealed significant differences in the DeFocus curves, with emphasis on PanOptix® and FineVision, which showed uniformity and stability at multiple distances. Hybrid lenses, such as Vivinex Gemetric, combined good visual performance and lower incidence of aberrations. While the optimized redistribution of light in trifocal lenses declared superiority in visual acuity at all distances, and the most reported side effects were halos and glare, especially in the initial postoperative period, with a tendency to decrease due to neurovisual adaptation. Furthermore, general satisfaction was high, with reduced dependence on glasses and improved quality of life of patients. It is therefore concluded that IOLs Premium trifocals are highly effective in visual correction and present significant clinical benefits for each situation sought in Brazilian clinical practice, despite some adverse effects.
