Binocular Visual Discomfort after First Eye Cataract Surgery: An Inattentive Burning Issue

Cataract surgery is the most frequent surgical procedure performed among the elderly. Aniseikonia and anisometropia increased after the first eye cataract surgery. The study was performed to evaluate unwanted visual status after first eye cataract surgery. It was an observational and cross-sectional study performed among the cataract surgery patients attending in out patient department (OPD) of Dr K Zaman BNSB Eye Hospital, Mymensingh from July 2018 to September 2018 for post-operative follow up. Five hundred patients were selected randomly. Patients with gross corneal diseases were excluded from the study. Three hundred forty one patients (68.2%) were with first eye cataract surgery, among them 319 patients (63.8%) had different degree of cataract in other eye. One hundred forty three patients (44.7%) had good presenting vision (≥6/18) in operated eye and much reduced vision in other eye due to cataract, experienced binocular visual discomfort when opened two eyes, which was not experienced by the patients who had reduced vision in both eyes or good vision in both eyes. Cataractous eye interfered with visual function of the pseudophakic eye. So, cataract Surgery for both eyes in separate events is the appropriate treatment for the patients with bilateral cataract to eliminate visual disability and to achieve comfortable visual outcome.
