Intraocular lens centration and stability: efficacy of current technique and technology.
OBJECTIVE
The manuscript presents a review of recently published studies analyzing different methodologies to assess centration and stability of intraocular lenses after implantation.


RESULTS
Considering that there is no current gold standard for centration and stability of intraocular lenses after implantation, we have summarized the different techniques used clinically for intraocular lenses centration and stability estimation. We have described the use of Scheimpflug imaging, the anterior segment optical coherence tomography and photography analysis used for lens position estimation. Techniques used to assess lens rotation are based on image analysis on digital retroillumination images.


CONCLUSIONS
Centration and stability of intraocular lenses are a matter of most importance and many methods have been developed. It seems that the best method for the assessment of lens position considers Scheimpflug imaging and for stability the use of retroillumination images.
