Comparative Analysis of Changes in the Macular Region Following Cataract Surgery by Phacoemulsification with Ozil Intelligent Phaco Technology According to Different Fluidics Parameters

AbstractPurpose To assess the change in macular thickness values following cataract surgery by phacoemulsification with Ozil Intelligent Phaco (IP) technology comparing high and low fluidics parametersMethods A randomized, prospective, comparative trial, including 40 eyes with age‐related cataracts and nuclear opalescence below 4 in the The Lens Opacities Classification System III (LOCS III). Half of the eyes were assigned to phacoemulsification with low fluidics (300mmHg vacuum and 20cc/min maximum aspiration flow), and the other half to high fluidics (500mmHg vacuum and 40cc/min maximum aspiration flow). Data were collected from the thickness map of the macular region by optical coherence tomography (OCT) prior to surgery as well as successive visits in the first postoperative monthResults All the sectors of the macular thickness in OCT were compared based on fluidics groups. No statistically significant differences in none of the 9 sectors in the macular region at both preoperative and first postoperative month were found. There was a slight increase in overall macular thickness after cataract surgery in both study groups, with no significant differences between both. However, this increase was not clinically significantConclusion Modifying fluidics parameters in phacoemulsification surgery with Ozil IP technology does not change the damage parameters into the macular region due to surgical trauma within the first 30 postoperative days
