[Fluorometric estimation of corneal endothelium functions in emmetropic and myopic eyes in pseudophakia]

The aim of the study was to calculate the corneal endothelial permeability (Pac) before, one week, and one month after planned extracapsular cataract extraction and intraocular posterior chamber lens implantation in two groups with axial myopes (8 eyes) and normal eyes (6 eyes): in patients aged 60-75 years. Patients with minimal endothelial disorders have been found to have abnormal endothelial permeabilities. Each operated eye was submitted to fluorophotometry of the anterior segment with measurement of corneal endothelial permeability (Fluorotron Master, Coherent), the day before surgery, 1 week and 1 month afterwards. The measuring of cornea thickness measurement and endothelial cell counting was done by specular microscopy with pachymeter. Corneal permeability clearly increased 1 week after surgery in both groups; 1 months after surgery Pac was normalized in both groups, except for all pseudophakic myopic eyes (axial length: 25-27 mm) with longer surgical procedures (> 20 min), those associated with a greater increase in corneal endothelial permeability. No changes in corneal thickness and endothelial cell density were noted as a result of surgery. Myopic eye with longer surgical procedures was found as a risk factor for an increase in corneal endothelial permeability.
