Abstract: PURPOSE: To study change in the contact of intraocular lens (IOL) with the posterior capsule with respect to the vertical versus horizontal orientation of the haptic-optic junction of the IOL using intraoperative spectral domain optical coherence tomography (SD-OCT). METHODS: Fifty eyes of 50 patients with senile immature cataract underwent topical phacoemulsification procedure with implantation of a monofocal IOL by a single experienced surgeon. The Rescan 700 SD-OCT system was used for intraoperative imaging. These patients were imaged using intraoperative SD-OCT after implantation of IOL, with the haptics oriented horizontally and then vertically. RESULTS: The vertical height between the posterior surface of the lens capsule and the posterior surface of IOL reduced significantly when the haptics were oriented vertically compared to horizontal orientation. This difference was found on analyzing both vertical as well as horizontal axis scans. CONCLUSION: We found a greater contact between the posterior capsule and the posterior surface of IOL, with the haptic optic junction of the IOL oriented vertically. This study also suggests the need for newer toric IOL designs which allow vertical orientation of haptics, leading to better contact between IOL and the bag.
