Abstract :
Aim: To compare endothelial cell density, central corneal thickness changes and evaluate best corrected
visual acuity after small incision and phacoemulsification cataract surgery.
Materials and Methods: In this prospective study, patient were presented with significant cataract.
Cataract were graded using lens opacities classification system grading. Forty three patients underwent
phacoemulsification and forty-one underwent SICS. Patient with any other ocular pathology were excluded.
Phacoemulsifiaction was performed, the chop-stop technique and SICS by the viscoexpression technique.
The endothelial cell count and central corneal thickness were measured by non-contact specular microscope
and best corrected visual acuity evaluated by snellen chart preoperatively and postoperatively on day 1st ,
3rd and 6th week respectively.
Result: The mean endothelial cell loss (cells/mm2) in phacoemulsification was 194.28 (7.16%), 311.46
(11.48%) and 412.16 (15.20%) and in SICS was 155.41 (6.17%), 230.19 (9.14%) and 296.54 (11.89%)
and was statistically significant (P
from 530.4412.34 micron increased by 62.62 micron (11.80%), 17.88 micron (3.37%)and 6.04 micron
(1.13%) in phacoemulsification and 523.246.63 micron increase by 38.05 micron (7.26%), 21.24 micron
(4.05%) and 2.63 micron (0.50%) in SICS at day is1; 3rd week and 6th week respectively. There was
statistically significant (P
phacoemulsification and 92.68% after SICS. There was statistically significant.
Conclusion: No significant differences in endothelial less loss, central corneal thickness and best corrected
visual acuity in between phacoemulsification and SICS.
