The role of the ocular surface diseases in the pathogenesis of cataract surgery complications

Purpose. To evaluate the possible role of the eye surface in the occurrence of residual ametropia and other complications after cataract surgery analyzing scientific ophthalmological data on this topic for the last five years. Material and methods. Analysis of domestic and foreign scientific ophthalmological literature over the past ten years. Results. There is a paradigm shift in the understanding of DES from a simple deficit of tear film to a chronic disease of the eye surface, followed by a complex of changes in all its structures. Conclusion. DES is an optical impairment and measurement of refractive parameters in patients with DES who will undergo cataract surgery is impossible. This leads to refractive errors in IOL power calculations and requires further keratorefractive operations to obtain high visual functions Key words: refractive errors, ametropia, ocular surface, dry eye syndrome
