Abstract Details

Purpose:

This half trench chop technique provides relative control of dividing hard nuclei can overcome the tightly packed fibres and makes chopping of such nuclei safer and decreases high ultrasound energy.

Setting:

This study was performed at the Department of Ophthalmology, Sohag University, Egypt.

Methods:

The study was conducted on 50 eyes with dense hard cataracts in the period between March 2018 to June 2018. The cataract grading was ranging from grade NC5 to grade NC6 according to The Lens Opacities Classification System III (LOCS III.

Results:

The mean machine phacoemulsification time was 12.35 ± 1.65 seconds (range 11.60 to 14.11 seconds) without significant difference in effective phaco time as regard to degree of nuclear hardness (P=0.589), which ensure the effectiveness of the technique in all cases. Posterior capsule rupture did not occur in any case. Clear cornea was observed on the first postoperative day in 45 eyes and mild early postoperative corneal edema in 5 eyes which completely resolved within a weak with medical treatment. Visual rehabilitation was early and rapid in all cases.

Conclusions:

: the half trench chop technique offers a relatively safe and a comfortable phacoemulsification technique in patients with rock hard cataracts and leathery posterior plate. Also, it has not steep learning curve and if it fails, could easily converted into stop and chop or divide and conquer techniques.
