Abstract:
Objective Acrysof IQ Restor multifocal toric intraocular lens ( IOL) is a new product , which allows a single sur-gical procedure for presbyopia correction and corneal astigmatism management .This study was to evaluate the early clinical effects of phacoemulsification cataract surgery with implantation of a diffractive multifocal toric IOL . Methods We retrospectively analyzed 7 cases (9 eyes) of corneal astigmatism ≥1.0 diopter (D) treated by phacoemulsification with implantation of an Acrysof IQ Restor toric IOL.The patients were followed up for 3 months for observation of uncorrected distance visual acuity ( UDVA) , best corrected distance visual acuity ( CDVA) , uncorrected near visual acuity ( UNVA ) , best corrected near visual acuity ( CNVA ) , spherical equivalent (SE) refraction, focal depth, residual astigmatism, rotational stability of the IOL, contrast sensitivity (CS), and spectacle independ-ence preoperatively and at 1 week, 1 month, and 3 months after operation . Results At 3 months after surgery , the UDVA ( log-MAR), CDVA, UNVA, and CNVA were 0.07 ±0.10, 0.02 ±0.11, 0.12 ±0.06, and 0.08 ±0.07, respectively, with an SE re-fraction within ±0.50 D of the attempted spherical correction in 8 eyes (88.9%) and a focal depth of (5.32 ±1.78) D.The residual astigmatism at 3 months was significantly reduced as compared with the baseline ([0.25 ±0.28] vs [1.55 ±0.39] D, P<0.05), but showed no statistically significant differences from the preoperative an-ticipated residual astigmatism (P>0.05).At 3 months, the mean IOL axis rotation was (3.11 ±1.61)°and CS was remarkably im-proved ( P<0 .05 ) , while CS with or without glare was not significantly different from that at 1 month at all spatial frequencies ( P>0.05) except at 18.0 cpd (P<0.05). Conclusion Implantation of the Acrysof IQ Restor multifocal toric IOL provides excellent overall quality of vision, spectacle independence, visual quality, and rotational stability for patients with cataract and corneal astigmatism.
