Purpose
To evaluate the magnitude of intraocular lenses transversal shift (ITS) after phacoemulsification and to analyse the factors contributing intraocular lens (IOL) decentration and ITS.
Setting
Ophthalmogy unit, Policlinico Casilino, Rome, Italy
Methods
Consecutive patients who underwent cataract surgery and IOL implantation were enrolled. Every patient underwent anterior segment optical coherence tomography (AS-OCT) with CASIA 2 (Tomey, Nagoya, Japan) to assess lens decentration, lens thickness and lens diameter 7 days preoperatively and at 1 and 60 days postoperatively. Different IOL models were implanted and the analysis of variance (ANOVA) was performed to evaluate the difference of ITS and iol decentration 2 month after surgery for each IOL. Univariate and multivariate linear regression analysis were performed to evaluate the determinants of ITS and final decentration.
Results
No statistical differences in the IOL final decentration and the ITS were found among each group of IOLs. The preoperative lens diameter was associated with the ITS and with the IOL final decentration. A positive association between the final IOL decentration and the first post-surgical day decentration was found (p< 0.0001).
Conclusions
Greater lens diameter was associated with greater decentration and with greater ITS. The day-1 IOL decentration seems to be the main determinant of final IOL decentration. No difference in decentration was found between the different IOL models.
