Study Population

This will be a prospective study of 30 patients with senile or complicated cataract scheduled to do phacoemulsification surgery in Tanta University Hospital

You may qualify if:

  • \- Presence of a nuclear, cortical cataract or complicated cataract due to diabetic mellitus
  • Intraocular pressure (IOP) of 21 mm Hg or lower
  • Axial length (AL) between 20.0 mm and 25.0 mm.

You may not qualify if:

  • Eyes with an AL longer than 25.0 mm or shorter than 20.0 mm,
  • IOP higher than 21 mm Hg,
  • History of ocular trauma or intraocular surgery, or any abnormal intraocular findings
  • Poor OCT-A images because of severe cataracts or unstable fixation
  • Any signs of intraoperative or postoperative complications
