KERATOPLASTY Symptoms, Causes & Treatments


Keratoconus we see through the cornea
which is the clear central part of the front surface of the eye the cornea
normally has a round shape like a ball sometimes however the
structure of the cornea is not strong enough to hold this round shape over
time the normal round curvature of the surface of the eye can bulge outward
like a cone this condition is called keratoconus keratoconus usually begins
in the teenage years but it can also start in childhood or up to about age 30
in some cases keratoconus is diagnosed at a later age but usually only because
it is very mild the changes in the shape of the cornea occur slowly usually over
several years keratoconus changes vision in two ways as the cornea changes from a
ball shape to a cone shape the smooth surface also warps this change is called
irregular astigmatism which cannot be fully corrected with glasses as the
front of the cornea steepens the eye becomes more nearsighted poor
vision at distance only nearby objects can be seen clearly as a result the
person may need new eyeglasses more often symptoms the main symptoms of
keratoconus are the following the vision in one or both eyes gradually gets worse
usually in late adolescence the person has doubled vision when looking with
just one eye even with glasses on bright lights look like they have Halen’s
around them someone with keratoconus will notice that his or her vision
slowly becomes distorted the change can end at any time or it can continue for
several years in most people who have keratoconus both eyes are eventually
affected causes the cause of keratoconus is largely unknown some studies have
found that keratoconus runs in families and that it happens more often in people
who have certain medical conditions but in most
cases there is no eye injury or disease that explains why the eye starts to
change patients with keratoconus tend to rub their eyes a lot which may cause the
condition to develop more rapidly treatments there are several methods for
treating keratoconus depending on how severe the condition is in the early
stages of the disease vision can be corrected with normal eyeglasses or soft
contact lenses as keratoconus gets worse vision may no longer be correctable with
eyeglasses because of the amount of irregular astigmatism and so the patient
may need to be fit with a special type of hard contact lens for some patients
the disease may advanced to a stage at which they do not have acceptable vision
even with glasses or contact lenses at this point the doctor may recommend a
cornea transplant which is a surgical procedure to replace the cornea with a
cornea from a donor two treatments for keratoconus that have recently been
approved by the Food and Drug Administration are implantable ring
segments often referred to as int X and corneal cross-linking implantable ring
segments are small devices that are inserted into the cornea to improve
vision or make it easier to fit a patient with contact lenses in this
procedure which is performed under local anesthesia the patient’s eye is numbed
the doctor creates pockets in the cornea and inserts the Rings into these pockets
the Rings help to flatten the cornea and partially reverse the cone shape caused
by the keratoconus corneal cross-linking uses a special type of ultraviolet light
treatment that may slow or stop the keratoconus from getting worse in
patients who are in the earliest stages of the disease in this procedure the
patient also receives local anesthesia the eye is numbed drops of riboflavin
vitamin b2 are put into the eye for up to 30 minutes the eye is then exposed to
an ultraviolet light for up to 30 minutes the corneal cross-linked
procedure is designed to increase the amount of collagen cross-links in the
cornea which can help keep the cornea from steepening not all patients with
keratoconus are candidates for these treatments your doctor can help to
decide which if any of these treatments may help you every individual needs
unique treatment and care we encourage people with keratoconus and their
families to learn as much as possible about the latest medical treatment and
approaches as well as healthy lifestyle choices please subscribe and comment if
you have any latest medical treatment for this illness stay strong
live long thank you
