Application of intraocular multifocal toric lenses in the correction of presbyopia and corneal astigmatism in cataract surgery – analysis of the refraction outcome and axial stability of the AcrySof® IQ PanOptix TFNTx Intraocular Lens

Abstract

Purpose: To evaluate distance, near and intermediate visual acuity, objective refraction, corneal keratometry and rotational stability after cataract surgery with an implantation of multifocal toric AcrySof® IQ PanOptix TFNTx intraocular lens in one-year follow-up. Material and methods: A total of 20 eyes of 14 patients underwent 2.2 mm coaxial cataract surgery with an implantation of AcrySof® IQ PanOptix TFNTx intraocular lens. Before surgery uncorrected and best-corrected distance visual acuity, objective refraction and corneal keratometry were evaluated. Twelve months after the surgery uncorrected and best-corrected distance visual acuity, uncorrected near and intermediate visual acuity, objective refraction, corneal keratometry and rotational stability of the implant were analyzed. Results: One year after the surgery there was statistically significant improve-ment of uncorrected and best-corrected distance visual acuity (p = 0.005 and p = 0.016). There was no significant change in corneal keratometry in flat and steep meridian (p = 0.94 and p = 0.63) and keratometric cylinder (p = 0.49). There was statistically significant decrease in objective refraction cylinder (p = 0.002). The mean rotation of an implanted intraocular lens axis was 2.51°. There were no intra- and post-operative complications in any of the patients. Conclusions: AcrySof® IQ PanOptix TFNTx intraocular lens implantation is a safe and effective method to correct presbyopia coexisting with corneal astigmatism during cataract surgery.
