Assessing scleral toricity induced lens flexure and contact disparity using anterior segment optical coherence tomography

Scleral toricity was significantly associated with AS-OCT measured lens flexure and contact disparity at primary toric landing locations defined by profilometry. Reducing central FR depth appears to be a good strategy for improved lens centration. Whilst equalising lens contact along toric meridians is beneficial for addressing lens flexure, the influence of this on centration is less clear.
