摘要
Purpose: To evaluate changes in angle kappa after the implantation of a trifocal intraocular lens (IOL) and to assess the postoperative outcomes of patients with different angle kappa values. Setting: IOA Madrid Innova Ocular, Madrid, Spain. Design: Prospective trial. Methods: Sixty-three eyes from 63 patients who had bilateral implantation of a diffractive trifocal IOL (POD F, PhysIOL) were included. Pupil offset was used as the best estimate of angle kappa and was measured using Pentacam (Oculus) preoperatively and at 3 months postoperatively. Postoperative refractive outcomes (sphere, cylinder, and manifest refraction spherical equivalent) and visual outcomes at far, intermediate, and near distance were assessed and compared between eyes with small pupil offset and eyes with large pupil offset. Quality of vision was assessed using a subjective questionnaire. Results: There was a significant decrease in pupil offset values postoperatively (mean: 0.197 +/- 0.12 mm) compared with those preoperatively (mean: 0.239 +/- 0.12 mm), with a mean decrease of -0.042 mm (P = .0002). The same significant decrease was found for both right and left eyes, when analyzed separately. No statistically significant difference was found in any of the refractive and visual acuity outcomes between eyes with small pupil offset and eyes with large pupil offset. The majority of patients (14 of 16) complaining of significant halos had eyes with small pupil offset. Conclusions: Large pupil offset did not negatively affect visual and refractive outcomes. The tolerance to larger pupil offset might be due to the IOL optical design, with the first diffractive ring being larger than other commonly used multifocal IOLs. More studies comparing various diffractive IOL models would be useful to confirm such hypothesis. Copyright (C) 2020 Published by Wolters Kluwer on behalf of ASCRS and ESCRS
