Anterior Chamber Morphometry With Combined Placido Scheimpflug Imaging–Based Topography System in Patients Before and After Phakic IOL Implantation
Purpose
To evaluate and monitor the anterior chamber morphology parameters in pre and post posterior chamber phakic IOL (ICL) implantation using a combined placido-Scheimpflug imaging based topography system (SIRIUS).
Methods
Measurements of anterior chamber morphology were done in patients before and after the implantation of ICL using combined Placido-Scheimpflug imaging based topography at 1week, 1 month and 3 months follow-up and were statistically analyzed.
Results
The mean HVID pre and post ICL implantation was 11.96mm and 12.62mm; mean CCT was 0.516 and 0.517mm; mean AD was 3.11mm and 2.66mm; mean AC volume was 172mm3 and 161mm3; mean iridocorneal angle was 44.32 and 30.90 degrees; mean HACD was 12.37 and 11.81mm and mean corneal volume was 56.0 mm3 and 56.35 mm3.
Conclusion
A complete preoperative and post-operative anterior chamber morphological evaluation especially of central anterior chamber depth and iridocorneal angles can help monitor the changes occurring after ICL implantation and to detect any alteration which can have impact on the post operative anterior chamber anatomy.
