Comparative analysis of postoperative results of cataract surgery using monofocal IOLs

Abstract

One of the most common surgical interventions in ophthalmology today is lens replacement surgery. But there is still no consensus on whether the choice of a monofocal IOL affects the postoperative functional outcome.The aim: to conduct a comparative analysis of values of visual acuity without correction in the early postoperative period after cataract surgery using monofocal IOLs.Material and methods. The study included data of 2643 eyes operated for cataract, into which one of the monofocal IOLs, included in the top ten most frequently implanted IOLs in the Orenburg Branch of the S. Fyodorov Eye Microsurgery Federal State Institution, was implanted for the period 2019–2021. Statistical analysis was performed using the program Statistica 13.0.Results. The performed analysis of variance showed that the established differences between the compared groups are statistically signifi cant (p < 0.05). However, the subgroup analysis showed that there were statistically signifi cant differences between pairs such as Tecnis and Hydro-4; Tecnis and Rayner. In all other cases, statistically signifi cant uncorrected visual activity (UCVA) values after surgery were not established. It has also been reliably established that the presence of subluxation of the lens affects the value of UCVA after surgery.Conclusion. The results of the performed analysis in general indicate that the value of UCVA in patients in the early postoperative period after the performed surgical intervention does not depend on the manufacturer of the used IOL.
