Abstract Details


Perfect astigmatism correction with toric intraocular lens (IOL) implantation requires an accurate IOL calculation and a precise surgical procedure. The purpose of our study is to compare refractive results obtained with and without intra-operative aberrometry and assess the manifest refractive errors after toric IOL implantation.

Retrospective study. Patients with topographic astigmatism higher than 1.5 D who underwent toric IOL implantation for cataract surgery and astigmatism correction (AcrySof® IQ Toric IOL and ReStor Toric, Alcon) where divided whether intra-operative aberrometry (ORA® System, Alcon) was used. In the group of patients operated without aberrometry, the implanted IOL was based on the surgeon best choice according to the online calculator for cylinder power (AcrySof® Calculator) and aligned with Verion® Image Guided System, Alcon. All patients were operated by the same surgeon with a capsular tension ring.


A hundred and nine eyes of 84 patients (28 and 81 eyes with and without intra-operative aberrometry respectively) were included. The groups did not differ in sex (p = 0.757) but the group with intra-operative aberrometry was significantly older (70.20±11.82 vs 63.44±13.35 years old; p=0.037). At 1-month post-op, spherical equivalent of manifest refraction was significantly lower in the group with intra-operative aberrometry (-0.16±0.35 vs -0.45±0.67; p=0.013). When the groups were compared for the residual astigmatism, the difference was not significant (-0.45±0.38 vs -0.43±0.42; p=0.518 with and without intra-operative aberrometry respectively).


On the basis of the clinical results of this study, toric IOL implantation guided by the more recent intra-operative aberrometry devices improves refractive outcomes in cataract surgery.
