Summary

The retro-chop technique for cataract surgery uses less ultrasound energy and reduces early corneal cell loss compared to stop-chop. This nuclear fracture method is effective and safe for severe cataracts.

Area of Science:

  • Ophthalmology
  • Surgical Techniques
  • Cataract Surgery

Background:

  • Phacoemulsification is a common cataract surgery method.
  • Nuclear fracture techniques are crucial for efficient lens removal.
  • Severe cataracts require effective and safe nucleotomy strategies.

Purpose of the Study:

  • To compare the outcomes of two nuclear fracture techniques: stop-chop versus retro-chop.
  • To evaluate intraoperative parameters and postoperative results of these techniques.

Main Methods:

  • 131 eyes with severe cataracts (grades 4-5) were randomized to stop-chop or retro-chop nucleotomy.
  • The Drysdale manipulator was used for chopping in both groups.
  • Phacoemulsification parameters, visual acuity, corneal endothelial cell density, and corneal thickness were compared.

Main Results:

  • Retro-chop demonstrated significantly less phacoemulsification time and power compared to stop-chop (p < 0.05).
  • A significant difference in early postoperative corneal endothelial cell loss was observed between the groups (p < 0.05).
  • No significant differences were found in corrected distance visual acuity or central corneal thickness postoperatively.

Conclusions:

  • Retro-chop nucleotomy using the Drysdale manipulator is an effective and safe cataract surgery technique.
  • This method reduces intraoperative ultrasound energy usage.
  • Retro-chop also minimizes early postoperative corneal endothelial cell loss compared to other techniques.
