Digital marking systems have been shown to be more accurate at positioning toric intraocular lenses and hence providing better visual outcomes. Patients with cyclodeviation and concomitant astigmatism undergoing toric intraocular lens placement present an extra challenge. We present a case of a patient with high astigmatism and a preexisting superior oblique palsy where using the Verion™ digital marking system proved to be an extremely valuable tool. We suggest that using this technology is especially helpful in patients with preexisting cyclodeviation and compensatory head tilt.

Purpose: To compare rotational stability, centration and visual outcomes provided by three trifocal lens models that have the same optical zone design but different material, composition, and/or toricity. Methods: The study included 78 patients with symmetric bilateral intraocular lens implantation. The lenses under evaluation were trifocal intraocular lenses made of hydrophilic acrylic material: a spherical lens 26% hydrophilic acrylic (POD FineVision), a similar lens but having a toric design (POD Toric FineVision), and a trifocal lens 25% hydrophilic acrylic material (FineVision/MicroF). Moreover, the lenses share the same optical zone design. The lenses’ rotational stability and centration were measured by means of the PIOLET software, which relies on recording and image processing techniques to determine lens rotation and centration based on slit-lamp images. We also assessed patients’ visual quality by means of 25, 40, and 80 cm VA tests. Results: The best centration results were achieved with the POD Toric FineVision model, although the differences were not statistically significant. As for lens rotation, it was below 5° in all cases under study. Regarding VA, all subjects attained at least 0.3 logMAR for far distance uncorrected VA, at 80 cm VA was about 0.2 logMAR, at 40 cm it was above 0.15 logMAR, and at 25 cm it was about 0.3 logMAR for both lens types. Conclusion: All three intraocular lens models yield excellent visual results at far, near as well as intermediate distances. The POD FineVision and POD Toric FineVision models, with double C-loop design, yielded the best results centration-wise and rotation-wise. Differences had no clinical relevance.

Patients, who need cataract surgical treatment, often fail to achieve a high uncorrected visual acuity after surgery due to the concomitant astigmatism involved. Currently, surgeons are increasingly performing combined surgical interventions, including relaxing limbal keratotomic incisions (manual keratotomy) or femtoarcuatous keratotomy, as well as implanting toric intraocular lenses. In recent years, additional toric intraocular lenses have been available. Purpose: to analyze our own clinical experience of implanting an additional toric intraocular lens to correct corneal astigmatism in three clinical cases. The article presents our clinical experience of successful correction of residual corneal astigmatism after previous cataract phacoemulsification with the implantation of a monofocal toric intraocular lens in three patients patients aged 70, 61 and 54 years. In all cases, an additional toric intraocular lens Add-on Torica-sPB pre-filled in the cartridge with a good refractive effect was implanted. The uncorrected visual acuity was 1.0 in all the investigated cases at the follow-upo period of 6 months after the surgical intervention. Calculation of the toric intraocular lens optical power was performed using an online calculator. A feature of surgical intervention was the repositioning of the additional toric intraocular lens into the ciliary sulcus. Changes in the data of keratotopography before and after surgery were absent. In none of the investigated cases, intra- and postoperative complications and dislocation of the implanted additional toric intraocular lens were determined. Based on these cases, high predictability, efficacy and safety of implantation of an additional toric intraocular lens are shown, in the case of residual middle-grade corneal astigmatism after the initial cataract phacoemulsification with the toric intraocular lens implantation. This approach can be successfully used in patients during one-stage surgical treatment of cataract and associated high-grade corneal astigmatism, expanding existing protocols for the treatment of this group of patients.
