Abstract
- Purpose: To investigate the influence of posterior capsular opacification (PCO) and Nd:YAG laser capsulotomy on central macular thickness (CMT) and signal strength (SS) measured with Stratus optical coherence tomography (OCT). Materials and Methods: In this prospective interventional case series, 72 eyes of 69 patients with PCO were enrolled for the study. A complete ophthalmologic examination and measurements of SS and CMT by Stratus OCT before and after Nd:YAG capsulotomy were performed. The patients were classified in two different forms based on PCO score and signal strength (SS) obtained with prelaser OCT scans. Results: The preoperative and postoperative mean CMT were 155±27 μm and 163±33 μm, respectively (p=0.019). Mean preoperative SS was 5.6±1.3 which improved to 8.6±1.5 postoperatively (p<0.001). Eyes with preoperative SS less than 6 had significant difierence between prelaser and post-laser CMT (p<0.05). Also, there was a significant increase after laser capsulotomy in CMT in patients with preoperative PCO grade more than 2 (p<0.05). Conclusion: CMT and SS measured by Stratus OCT is influenced by PCO. CMT may be underestimated in eyes with PCO grade more than 2 or in eyes with preoperative SS less than 6. [ABSTRACT FROM AUTHOR]
