PURPOSE: To evaluate the influence of cataract on scanning laser polarimetry. METHODS: Nerve fiber layer thickness (NFLT) around the optic nerve head was measured before and after surgery in 43 eyes of 43 patients with cataract. Phacoemulsification-aspiration and intraocular lens implantation was performed in all eyes. RESULTS: The mean NFLT increased 13.41% (p < 0.0001) postoperatively. Positive correlation(rs = 0.56, p = 0.001) was observed between NFLT measurements and cataract degree, using Lens Opacities Classification System III. Significant positive correlation(rs = 0.493, p = 0.004) was observed between NFLT measurements and posterior subcapsular cataract degree. CONCLUSION: Scanning laser polarimetry may underestimate NFLT in individuals with dense cataract.
