Study Population

The study population will consist of adult patients aged 40 years and older diagnosed with cataract and scheduled for phacoemulsification surgery at Assiut University Hospital.

You may qualify if:

  • Age equals to or above 40 years old
  • cataract patient
  • suitable for phacoemulsification
  • clear corneal media

You may not qualify if:

  • previous corneal surgery
  • advanced glaucoma
