Introduction: Cataract surgery with artificial intraocular lens implantation is one of the most frequently performed operations in ophthalmology. A standard monofocal intraocular lens does not correct preoperative astigmatism; such patients benefit from correction with a toric lens. In order to preserve optical properties of the toric lens, it must remain in a stable position in the postoperative period, as any rotation reduces its optical performance. Aim of the study: To evaluate functional results and to compare the spontaneous rotation of two models of toric intraocular lenses (IOLs) implanted during phacoemulsification in patients with preoperative corneal astigmatism. Material and methods: Two groups of patients were evaluated after planned standard phacoemulsification surgery with implantation of a toric IOL. Patients who fulfilled the inclusion criteria and consented to participate were randomly assigned to one of the groups. Based on the anterior segment photography the toric lens rotation was calculated with purpose-designed ToriCalc software. Results: No statistically significant between-group differences in mean best corrected distance visual acuity (BCDVA) or uncorrected distance visual acuity (UCDVA) were found preoperatively or during the follow-up. In both groups a postoperative significant increase in UCDVA and BCDVA was observed. The rotation of the toric IOL was similar and not significant in both groups (p > 0.05). Spherical and cylindrical residual refractive errors were significantly lower after the surgery in both groups. Conclusions: Both examined IOLs offer excellent and similar rotational stability and very good functional results. The software-guided postoperative evaluation of rotational stability of toric IOLs is a good method of evaluating their position. [ABSTRACT FROM AUTHOR] |
