The main goal to focus on corneas which is reduce something like cone which is different from normal corneas.

2.  In 1963, scientists found that the initial
changes of Keratoconus were related to break
down of the corneas basement membrane
like conical shape.
 They found that this cause happens due to
thin of cornea and its shape changes as a
conical.

5.  From the above figure investigator conclude
that enzyme activity of Keratoconus increase
gradually compare to normal eye.
 In this case cornea is responsible for 80% of
the absorption of ultraviolet B(UVB) light that
enters the eye.
 Ultraviolet create free oxygen radicals, high
energy molecules, which if unchecked can
damage tissue.

7. Pre-op Post-op

8.  Keratoconus corneas produce enzyme which
is unique not found in normal corneas.
 The main goal to focus on corneas which is
reduce something like cone which is different
from normal corneas.

15.  Axial:-
Distance to reference point not curves.
 Tangential:-Local or true curvature best of
shape.

16.  Treatment is categories into two parts
conservative and surgical.
 Now Surgical removing central nodular scars
by shaving the corneal surface may improve
contact lens and decrease the rate of
associated corneal abrations.
 But conservative treatment take place without
any operation and intervention.

18.  Placement of Intacs using manual dissection
technique appears to be efficacious treatment
modality for keratoconus.
 Most patients achieve better spectacle
corrected visual acuity with concurrent
decrease in astigmatism.
