can feel the light and darkness but can't see clearly.

age of 40 or it may occur due to some disease of the eye or some

-
ECCE (Extra Capsular Cataract Extraction):
Whole cataract is extracted and capsule is left behind. Lens is
kept in the capsular bag. In this procedure the incision is 12
to 14mm and sutures are done.
-
Phacoemulcifitation :In this procedure cataract
is dissolved or emulsified with ultra sound in to small pieces
and sucked out through the small incision. Then Intra Ocular
Lens (IOL) is placed in the capsular bag. Here the incision
is 5 to 6mm and no need of sutures.
-
Phacoemulcification with Foldable IOL :This is
the most advanced techique. In this surgery a soft lens which
can be folded, is implanted through a incision of 2.8 to 3mm.
Obviously no need of sutures.
Benefits of foldable IOL :-
+
No Sutures.
+
No Injections.
+
No Ped.
+
No Hospitalization.
+
No Need of rest.
+
No Glass (Multifocal).
+
Less Astigmatism.
+
Less Complications.
+
Less PCO.
