3.  Penetrating keratoplasty is a surgery where the opaque cornea of the patient is transplanted with the clear cornea from the eye of the deceased individual to provide vision for the patient  It can be done if the scar is not very long standing Picture of PKP Treatment

4. Role of the counsellor  Should explain the advice of the doctor whether it is tabtooing, cosmetic contact lenses or penetrating keratoplasty  The need for regular follow up and proper complained with treatment for a long duration, especially after PKP also has to be stressed  The chances for graft rejection after PKP and the necessity for glass for good vision after surgery also should be explained

5.   There are ocular emergencies which can vary in severity from mild damage to potentially blinding conditions   The cause can be chemical or mechanical   They affect any age group especially children and working adults’   They can have severe pain, glare and loss of vision Injuries

6.  Stressing the necessity for urgent treatment  Reassuring and insisting the need for proper follow up and compliance with medication  The possibility of searing and its management will also have to be explained  Counselling on protective measures and care to prevent such recurrent episodes Role of the counsellor

10.  Usually there is no visual loss and it is treated with eye drops mostly antibiotic drops and ointment  Rarely the cornea can be involved in viral conjunctivitis and EKC (Epidemic Kerato Conjunctivitis and causes defective vision Treatment

11.  Allergy to dust  Contact lens or pollen  Animal donator and is a non contagious type of conjunctivitis, but causes lot of Itching and discomfort Allergic Type

12.
