Initial corneal astigmatism is one of the leading problems affecting the refractive result after phacoemulsification of cataract (FEC). For its correction, various techniques were proposed, which were simultaneously performed with cataract surgery, in order to obtain high-quality vision without additional correction.Purpose. To perform a comparative evaluation of various surgical methods in a simultaneous correction of the initial corneal astigmatism during the phacoemulsification of cataracts using the VERION system.Material and methods. Three groups of patients aged from 40 to 75 years were formed. All patients were diagnosed with cataract with concomitant regular astigmatism: the group 1 included 15 patients (15 eyes) with concomitant astigmatism from 2.0 to 6.0D, where the Ascrysof IQ TORIC lens was implanted; the group 2 – 15 patients (15 eyes) with concomitant astigmatism from 1.25 to 2.5D, where limbal slack (arcuate)incisions using a Femto LDV Z8 femtolaser were performed during the FEC; the group 3 – 12 patients (12 eyes) with concomitant astigmatism from 1.25 to 2.5D, where an arcuate incision was performed with a diamond keratotomic knife during archaic cataract phacoemulsification.Results. All patients received a reduction in the initial astigmatism in the group 1 up to 0.75±0.11 D, in the group 2 – to 1.0±0.25 D and to 1.15±0.25 in the group 3. Uncorrected visual acuity was 0.75±0.11, 0.59±0.14 and 0.49±0.18, respectively, that indicates an efficiency of the presented methods of surgical correction of corneal astigmatism during the FEC. The fastest recovery and stable results were achieved in patients with toric IOL implantation.Conclusion. The successful outcome of surgical cataract treatment in patients with concomitant astigmatism mainly depends on the correctness of the choice of treatment method, so a differentiated approach allows to achieve the maximum refractive result after the operation.
