Abstract
Purpose: To evaluate distance visual acuity, objective refraction, corneal keratometry and rotational stability after cataract surgery with an implantation of monofocal AcrySof® IQ Toric SN6ATx in a 6 months follow up.
Material and methods: A total of 40 eyes of 30 patients underwent 2.2 mm coaxial cataract surgery with an implantation of AcrySof® IQ SN6ATx. Before and six months after the surgery uncorrected and best-corrected distance visual acuity, objective refraction, corneal keratometry and rotational stability of the implant were analyzed.
Results: Six months after the surgery there was statistically significant improvement of uncorrected and best-corrected distance visual acuity (p = 0.00). There was no significant change in corneal keratometry in flat and steep meridian (p = 0.45 and p = 0.12) and keratometric cylinder (p = 0.49). There was statistically significant decrease in objective refraction cylinder (p = 0.00). The mean rotation of an implanted intraocular lens axis was 3,35°. There were no intra- and post-operative complications in any of the patients.
Conclusions: AcrySof® IQ Toric SN6ATx implantation is a safe and effective method to correct corneal astigmatism during cataract surgery
