Abstract
Fluorophotometry was carried out in 19 eyes with no pathology except for the presence of advanced cataracts. The age range was 60–75 and there was no evidence of systemic disorders such as diabetes mellitus or hypertension. The scanning fluorometer used (Fluorotron Master) was modified in order to improve depth resolution (0.585 mm). Corneal endothelial permeability (Pac) was calculated before surgery (Pac: 3.14 ± 0.60 × 10 -4 cm/min). In 11 eyes, corneal endothelial permeability was again measured one week after planned extracapsular cataract extraction and intraocular lens (IOL) implantation. The corneal endothelial permeability increased after surgery and this increase correlated well with duration of surgery. Longer surgical procedures (>20 min) were associated with greater increases in corneal endothelial permeability.
