RESUMEN
Purpose: To compare the posterior capsular opacification (PCO) after implantation of three types of hydrophobic square edge intraocular lenses (IOLs). Methods: A single-center, hospital-based, cross-sectional, observational study was conducted wherein patients with senile cataract who had undergone phacoemulsification by a single surgeon, with the implantation of three different types of square edge, hydrophobic IOLs [Group 1: enVista, Bausch and Lomb; Group 2: Tecnis 1 ZCBOO, AMO and Group 3: Acrysof IQ SN60WF, Alcon], and followed up for 12 months were included. The PCO was graded clinically and scored using the EPCO 2000 software. Results: 90 eyes of 90 patients were included. There was no significant difference in the PCO with respect to age, gender, or associated presence of systemic disease. The median PCO score was 0.035, 0.045 and 0.085 in groups 1, 2 and 3, respectively. The PCO grade and score differences between the groups were statistically significant with P < 0.001. Conclusion: The hydrophobic nature and posterior square edge design in the IOLs probably contributed to the minimal visually-significant PCO in all the groups, in our study. However, PCO scores were lesser in the square edge IOLs having a continuous 360 degrees posterior enhanced barrier, than those without this feature.

A 53-year-old man presented with a slow-growing mass in the right orbit and temporal area of 1 year duration following a road traffic accident. Examination revealed a nodular fungating mass involving the orbit, right temporal area with multiple discharging sinuses causing proptosis and restricted ocular motility. The patient denied light perception in the right eye. There was exposure keratopathy and optic atrophy. Imaging showed mass lesion of the orbit extending intracranially. Tissue biopsy and culture revealed a chronic granulomatous reaction due to deep infection with coagulase-positive staphylococci. The patient showed remarkable improvement to systemic antibiotics and anticonvulsants. Mortality is high in such cases due to intracranial extension if there is a delay in treatment. This case report summarises a rare aetiology and successful treatment of a case of chronic granulomatous reaction due to deep bacterial infection following trauma and is deemed rare as cases of primary orbital infection in immunocompetent have not been reported so far.
