Ocular biometry, keratometry reading and intra ocular pressure in age-related cataract patients with and without pseudoexfoliation syndrome

ABSTRACT

This study aims at making a comparison between Ocular Biometry, Keratometry Reading and Intra Ocular Pressure in age-related cataract patients with and without Pseudo Exfoliation Syndrome. A clinical-based cross-sectional study was carried out on 118 patients in 2008, with and without pseudoexfoliation syndrome who were candidates for age-related cataract surgery. Ocular Biometry, the related components including Anterior Chamber Depth, Lens Thickness, Vitreous Chamber Depth and Axial Length were measured using an A-scan ultrasound device. Corneal Power and Intra Ocular Pressure were also measured using keratometer and applanation tonometry, respectively. Of the 118 patient with mean age 68.97 +/- 11.02 years old, 49% were men. Mean age was 71.08 +/- 11.19 and 66. 91 +/- 10.54 years for male and female respectively. 36.4% of total patients had PXS and among them 21.2% of male and 15.3% of the females had Pseudoexfoliation Syndrome. In Ocular Biometry components, the mean of Anterior Chamber Depth was shallower in the patients with Pseudoexfoliation Syndrome than those without it [P=0.049]. Also mean Intra Ocular Lens power was greater in patients with Pseudoexfoliation Syndrome than those without it [p=0.046]. It seems that patients with age related-cataract along with Pseudoexfoliation Syndrome need larger Intra Ocular Lens power and have shallower Anterior Chamber Depth
