摘 要：AIM:To evaluate the refractive and visual outcomes following cataract surgery and implantation of a trifocal toric intraocular lens(IOL)in eyes with low degrees of corneal astigmatism.METHODS:Twenty-six eyes of 22 patients who underwent implantation a trifocal toric IOL(FineVision PODFT,PhysIOL s.a.,Liege,Belgium)were enrolled.Phacoemulsification with femtosecond laser,capsular tension ring insertion and intraoperative aberrometry were performed in all cases.All IOLs used showed a cylinder power of 1.00 D.Main outcome measures were refractive error and corrected-distance visual acuity(CDVA)and uncorrected-distance visual acuity(UDVA)values.Eyes were evaluated at 4 mo post-surgery.RESULTS:Totally 50%of eyes showed a spherical equivalent(SE)within±0.13 D and all of them within±0.50 D.The mean SE and refractive cylinder were-0.02±0.23 and-0.16±0.22 D,respectively.Vector analysis revealed that 100%of eyes were within±0.50 D for the SE and cylindrical components(J0 and J45).Refractive changes were not correlated with keratometric changes(P0.05)showing that the reduction in astigmatism comes from the trifocal toric IOL.Of 81%and 96%of eyes showed UDVA and CDVA of 20/20,respectively.The postoperative mean values of monocular distance Snellen decimal UDVA and CDVA were 0.97±0.05 and 0.99±0.02(about 20/20),respectively.CONCLUSION:Our study suggests that the use of this trifocal toric IOL in patients with low amount of astigmatism provides accurate refractive outcomes and enables them to achieve excellent visual acuity.
