Time analysis of corneal endothelial cell density after cataract extraction.

Serial endothelial photographs were taken preoperatively and postoperatively in 200 eyes; 111 eyes contained a Rayner iris clip lens, 54 eyes contained a Fyodorov Sputnik lens, and 35 eyes had no lens. Central endothelial cell density was changed in all instances, with counts in implanted eyes declining 25 to 30%, and in nonimplanted eyes 10 to 15%. In both instances, the decline essentially ceased at about three months. The cause of the greater decline in implanted eyes appeared to be mechanical and subsequent cell loss after the 90-day period was virtually equal for the two groups. Methods that may be used to alter the difference in cell density occurring with implantation are best analyzed by using the 90-day period data for comparison.

Binkhorst Lecture (Part 1). Experimental cataract surgery.

The use of intraocular lenses in cataract surgery leads to a greater corneal complication rate than surgical treatment without such devices. It has been assumed that the predominant reason for this is surgical trauma at the time of lens insertion. A laboratory study to verify and analyze this difference has been carried out, the cat being used as an experimental model. This first report evaluates the effect of the usual steps of cataract extraction on the density of corneal endothelial cells.

Binkhorst Lecture. (Part 2). Experimental cataract surgery--electron microscopy.

Scanning and transmission electron microscopic examinations were performed on cat corneas after the steps usually taken to perform cataract extraction were completed. The endothelium did not replicate, but showed nuclear division or segmentation occasionally. In each case, the anterior segment was free from any evidence of inflammation one year after surgical treatment--unless a pseudophakos had been inserted: in some of these cases, significant numbers of white cells were present, a condition that may contribute to anterior segment complications from implants.
