The effect of different toric multifocal intraocular lenses on clinical results

Objective: to compare the clinical visual characteristics of two different models of multifocal toric intraocular lenses (IOL). Material and methods. In a retrospective study, 49 eyes with corneal astigmatism > 0.75 dptr were divided into two groups. In group 1 (n=19), patients were implanted with an open haptic multifocal toric IOL Aery Sof IQ PanOptix Toric (Alcon), and in group 2 (n=30) - BB T MFM 611, VSY (Acriva Reviol). Observations were carried out 1,3,6 and 12 months after the operation. The degree of rotation of the IOL, residual spherical refraction and astigmatism, as well as uncorrected visual acuity near and far were evaluated. Results. There were no differences between the two groups in terms of uncorrected visual acuity in the distance (p=0.382), spherical equivalent (p=0.174), degree of astigmatism (p=0.062), degree of rotation (p=0.219) and uncorrected visual acuity near (p=0.712). However, there was a noticeable improvement in visual acuity in the distance (0.3 and 0.1) and near (0.1 and 0.1) compared with preoperative values in groups 1 and 2, respectively. Conclusion. Both lenses have shown comparable high clinical results, which suggests that it is possible to effectively correct astigmatism and provide sufficient uncorrected visual acuity at any distance.
