Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Investigators also investigated whether concentrations of immunoregulatory molecules significantly correlated with intraoperative and postoperative parameters. Particularly, investigators focused on the development of corneal edema as one of the main causes of low visual acuity in the immediate postoperative period after intraocular lens implantation.
Since disturbed cytokine and growth factor microenvironment in diabetic eye may contribute to an increased frequency of intraoperative and postoperative intraocular lens (IOL) surgery complications, the findings may be relevant for the development of therapeutic strategies aimed to restore protein profile of immunoregulatory factors in parallel to cataract treatment.
