Subjects were patients choosing to be bilaterally implanted with a trifocal IOL (PanOptix®) who were then evaluated 3 months postoperative. Angle kappa (AK) was measured before surgery and at the 3-month visit. The 3-month visit included a manifest refraction, and measurement of uncorrected and distance corrected acuity at 4 m, 60 cm and 40 cm. Visual quality and satisfaction questionnaires were also administered.Results: Data from 56 eyes of 28 subjects were analyzed; 26 eyes had an AK magnitude < 0.3 mm, 14 had an AK from 0.3 mm to less than 4 mm and 16 had an AK ≥ 0.4 mm. Neither visual disturbances (eg, glare, halos, starbursts), satisfaction nor spectacle dependence were correlated to the magnitude of angle kappa. The magnitude of postoperative AK was significantly lower than preoperative (0.24 ± 0.12 mm vs 0.30 ± 0.16 mm, p < 0.01).Conclusion: The magnitude of preoperative Angle Kappa had no apparent effect on the refractive, visual acuity or subjective (visual disturbances, quality of vision, satisfaction) clinical outcomes with this trifocal IOL. The magnitude of angle kappa was significantly lower after surgery.Keywords: angle kappa, trifocal IOL, cataract surgery |
