One of the directions of advancing phaco technology is related to adoption of hybrid phacoemulsification for clinical practice. Potential postsurgical changes in the macular area, when other factors are equal, can be seen as a conditional criterion for the injury rate of phaco surgeries. Purpose – to evaluate morphological and functional condition of the macular area after different types of phaco cataract surgeries. Material and methods. Two groups were formed for comparative study in accordance with criteria for standardization and maximum mitigation of the impact of other factors on the condition of the retina – with standard ultrasound and hybrid (femtolaser-assisted) phacoemulsification (30 operations in each group). Examinations were performed initially, then 7–10 days, and 2–3 month after the surgery. Optical coherence tomography (OCT) and multifocal electroretinography (mfERG) were performed for evaluation of the morphological and functional condition of the macular area. Results. There was no statistically significant dependence of linear and volumetric measures in the macular area on phaco surgery method, and the few variations were most likely related to increasing the time of ultrasound action in standard phacoemulsification. Revealed changes turned out to be significantly less marked than what is considered critical for development of macular edema. Improvement of baseline multifocal electroretinography measurements (increase of the density of retinal biopotential and decrease of latent time) just after the surgery results from the effect the lens opacification has on basic parameters, regardless of phacoemulsification technique. There were no significant differences in postsurgical measurements of multifocal electroretinography obtained in similar periods of postsurgical assessment after standard ultrasound and hybrid phacoemulsification. Conclusion. The results prove the safety of phaco surgery methods and the absence of negative impact of femtolaser component of hybrid phacoemulsification on structural and functional condition of central retina.
