Staging
Clinical staging of senile cataract is based largely on the visual acuity of the patient, as follows Hypermature cataract Patient generally sees worse than count fingers (CF) or hand motion (HM) owing to a dense white, deeply dark opaque brunescent, or Morgagnian cataract
Mature cataract Patient cannot read better than 20/200 on the visual acuity chart
Immature cataract Patient can distinguish letters at lines better than 20/200
Incipient cataract or dysfunctional lens syndrome Patient reports visual complaints but can still read at 20/20 despite lens opacity confirmed via slit lamp examination
