Abstract

Purpose: To investigate whether there is a difference between symptoms of floaters according to the type of ophthalmic viscosurgical devices(OVDs) used during phacoemulsification. Methods: A total of 112 eyes had undergone standard phacosurgery with the dispersive OVDs(Group1). Group2 comprised 117 eyes that underwent phacosurgery with the dispersive OVDs, but between continuous curvilinear capsulorhexis and hydrodissection, some OVDs had been removed. Group3 included 120 eyes that had undergone phacosurgery with the cohesive OVDs. Results: 14 eyes (12.5%) of Group1 had new-onset floater after surgery whereas 6 eyes (5.13%) in Group2, and 7 eyes (5.83%) in Group3 at the day after and a week after surgery. This was significantly higher in Group1 than Group2 and Group3, respectively (p=0.047,0.049). Conclusion: Cataract surgery with dispersive OVD can predispose the eye to an increased floater symptom. Therefore, surgeons should consider release some OVDs during hydrodissection with dispersive viscoelastics and keep trying to avoid IOP surge during surgery.

Percentage of patients with new-onset floater symptom during follow-up after cataract surgery in all study groups. The number of patients with postoperative floater symptom was significantly higher in Group 1 compared to other groups at 1 day and 1 week postoperatively. However, this difference was not significant after 1 month. (†Mann Whitney U- test < 0.05; Group 1: used dispersive ophthalmic viscosurgical devices (OVDs) and did not remove dispersive OVDs before hydrodissection. Group 2: used dispersive OVDs and removed some dispersive OVDs before hydrodissection. Group 3: used cohesive OVDs
