Rh. Johnston et al., ENDOTHELIAL-CELL ANALYSIS OF CORNEAS FROM DONOR EYES WITH AN INTRAOCULAR-LENS - A COMPARATIVE-STUDY, Cornea, 16(5), 1997, pp. 531-533
Purpose, Many eyes are received from patients who have undergone catar
act surgery. Few data document the endothelial cell characteristics in
these donor eyes, which have previously been disqualified for transpl
antation. We compared the endothelial characteristics of the corneas f
rom eyes with intraocular lenses (IOLs) with a group of matching contr
ols. Methods, The corneal endothelial characteristics, including cell
density, polymegethism, and pleomorphism, were prospectively obtained
in 15 corneas from eyes with IOL implants and compared with 17 phakic
control eyes. Results. The mean cell densities (+/-SD) were 2,495 +/-
438 cells/mm(2) for the eyes with implants and 2,576+/-264 cells/mm(2)
for the controls. The mean coefficient of variation was 0.307+/-0.04
and 0.323+/-0.04 for IOL and control group, respectively. No significa
nt difference was found between the two groups (t test, power = 0.97 i
n detecting a mean difference of 20%). Conclusion, Many eyes with IOLs
have endothelial cell densities comparable to those of phakic eyes. A
decision to use specific corneas should be made individually based on
endothelial cell analysis. Previous ocular surgery may not disqualify
a corneal donor.
