        <p>Purpose: To analyze refractive results after cataract surgery in relation to used type of monofocal intraocular lens, calculation formula, to age, gender and laterality. Settings: Department of Ophthalmology, Comenius University and University hospital in Bratislava, Slovakia Methods: We analyzed 173 eyes (118 patients) after uneventful cataract surgery. We calculated prediction error (PE) and mean absolute error (MAE) of postoperative refraction. Results and conclusion: We found no statistically significant differences in PE and MAE in relation to types of used IOL, calculation formulas, gender, age or laterality.</p>
