Figure 2. Relationship between the presence of either corticonuclear cataract or previous cataract surgery (phacoemulsification with IOL implantation) and the TBARS levels in the vitreous. Where an intraocular lens (IOL) is present in place of the natural lens, the thiobarbituric acid-reactive substances (TBARS) levels are significantly higher than in patients with cataract (1.39±0.64 vs. 0.75±0.45; p=0.003). Data are shown as means ± standard deviation (SD): n=20 (patients with cataract); n=22 (patients with IOL). * p≤0.003.
