Abstract Details
Purpose:
To compare the morphological (cell density, coefficient of variation and
standard deviation) and functional (central corneal thickness) endothelial
changes after phacoemulsification versus manual small-incision cataract surgery
(MSICS).
Setting:
Davangere Netralaya,Karnataka,India
Methods:
In this prospective randomized control study, patients
were randomly allocated to undergo phacoemulsification (Group 1, n = 100) or
MSICS (Group 2, n = 100) using a random number Table. The patients underwent
Complete ophthalmic evaluation and specular microscopy preoperatively and at 1and
6 weeks postoperatively. Functional and morphological endothelial evaluation was
Noncon ROBO PACHY SP-9000 specular microscope. Phacoemulsification was performed, the chop technique and MSICS, by the viscoexpression technique.
Results:
The mean difference in central corneal thickness at baseline and 1 week
between Group 1 and Group 2 was statistically significant (P = 0.027). However,
this difference at baseline when compared to 6 week and 1 week, 6 weeks was not
statistically significant (P > 0.05). The difference in mean endothelial cell
density between groups at 1 week and 6 weeks was statistically significant (P =
0.016). The mean coefficient of variation and mean standard deviation between
groups were not statistically significant (P > 0.05, both comparisons).
Conclusions:
The central corneal thickness, coefficient of variation, and standard
deviation were maintained in both groups indicating that the function and
morphology of endothelial cells was not affected despite an initial reduction in
endothelial cell number in MSICS. Thus, MSICS remains a safe option in the
developing world.
