To compare the outcomes of the phaco-chop and divide & conquer technique in micro incisional cataract surgery (MICS).
Jawaharlal Institute of Postgraduate Medical Education, Puducherry, India.
Eyes with nuclear density from grade 2 to 4 were randomly subdivided into 2 groups (phaco-chop, divide-and-conquer). Intraoperative parameters taken are ultrasound time (UST), mean cumulative dissipated energy (CDE), and balanced salt solution use. patients were examined preoperative and 1 day, 1 month, and 3 months postoperative for best-corrected visual acuity, central corneal thickness, and endothelial cell count.
There was no significant difference in both the techniques in Grade 2 and 3 cataracts. However, intraoperative measurements showed significantly less UST, CDE, and balanced salt solution use with the phaco-chop technique than with the divide-and-conquer in the grade 4 cataract density group (P<.05). Endothelial cell loss was also less in the phaco-chop technique in grade 4 cataracts.
The phaco-chop technique is found to be more effective in hard cataracts with less endothelial damage.
