The transparent outermost layer which covers the front of an eye is called the cornea. The cornea serves as a barrier against germs, dirt and particles that can harm the eye while playing a key role in vision. When light enters the eye, it gets refracted or bent by the cornea’s curved edge and this helps in determining how well you can focus on near and far objects. The cornea may get damaged by corneal disease, infection or any deep injury which impairs vision. The different conditions that affect the cornea can be treated to restore vision.The eye specialists at Keystone Eye Associates are a team of highly acclaimed ophthalmologists in Philadelphia City.

What is corneal transplant Surgery?
Corneal transplant surgery is used to treat various conditions, which include: keratoconus (cornea that bulges outward), Fuchs’ dystrophy, thinning, scarring, swelling or clouding of the cornea, corneal ulcers caused by infection and complications caused by any previous injury. Corneal transplant surgery restores the vision of the person by removing the damaged portion of the cornea and replacing it with a healthy donor tissue. The standard method of transplant is to surgically replace the complete cornea with the donor tissue through a method known as penetrating keratoplasty or full thickness transplant. It is the best method applied to treat advanced keratoconus, severe herpetic scarring or traumatic injury that affects the entire cornea. Lamellar keratoplasty or partial thickness transplant is another recent method which has been introduced for corneal transplant. This procedure involves the selective removal and replacement of diseased layer(s) of cornea with a healthy donor tissue. This method promotes better visual improvement and low risk of complications.
What is the treatment for corneal infections?
Corneal infection or Keratitis is the inflammation of the cornea which is caused by bacteria, viruses, parasites or fungi. This infection can also occur by overuse of old contact lens or improper cleaning of the lens. Eye doctors usually recommend antibacterial eye drops for treatment of minor corneal infections while treatment for severe infections requires a more intensive antibiotic or anti fungal with steroid eye drops prescribed to reduce inflammation.
What is the treatment for Dry Eyes?
The condition in which the eye produces low quality or few tears and is not able to keep its surface lubricated, is known as Dry Eyes. The ophthalmologist performs several tests to determine the exact cause of the condition and on the basis of the results; he/she devises a treatment plan. The treatment plan may include various treatment options such as artificial tear drops, ointments, tear stimulating drugs, eye drops that are made from the patient’s own blood, using special contact lenses, eyelid massage, light therapy and surgery that closes tear ducts in case of overflowing.
What is Pterygium Treatment and Surgery?
Pterygium is the condition in which there is a tissue growth of the conjunctiva (a layer covering the white part of an eye) into the cornea. A Pterygium can have different colors: pink, yellow or white and usually develops on the nasal side of the eye but can also occur on the lateral side or both sides. When Pterygium is mild, it can be treated with artificial eye drops, over-the-counter eye ointments and prescription steroids that reduce redness, irritation, swelling, pain, inflammation and dryness. When Pterygium is severe and it starts affecting vision then the eye doctor will recommend surgery to completely remove it. However, complications are linked with the surgery, such as a recurrence of the Pterygium in a more aggressive form, scars on the cornea or more blurry vision. Eye doctors only suggest Pterygium surgery for a number of reasons; if other treatment options have failed to work, Pterygium affects your vision and if it plays a role in impacting your appearance. The most preferred methods to surgically remove Pterygium are Conjunctival Autografting and Amniotic Membrane Transplant.
What is DSEK Surgery?
Descemet’s stripping automated endothelial keratoplasty (DSEK) is the latesttechnique performed in corneal transplantation. DSEK is the procedure of replacing the damaged endothelial layer (innermost layer of cornea) instead of removing all the layers of cornea which is done in standard corneal transplantation. DSEK is recommended for the treatment of corneal clouding which occurs due to dysfunction of only the endothelial layer while the other layers of the eye remain healthy. During the procedure of DSEK, a small incision is made on the side of the cornea and the diseased endothelial layer is peeled from the back of the cornea while healthy layers remain intact. Subsequently, healthy corneal donor tissue is placed inside the eye and the eye surgeon injects an air bubble beneath the cornea to make sure it is properly positioned in the place of the removed diseased layer. The incision is closed off with a single stitch while eye drops are also used to dilate the pupil.
What is PKP Surgery?
A damaged cornea due to disease, injury, infection, surgery or an improperly curved cornea can be corrected surgically through corneal transplantation or traditional full thickness corneal transplant. This procedure is also known as Penetrating Keratoplasty (PKP) in which a circular button-shaped, full-thick section of the tissue is removed from a damaged or diseased cornea and a healthy donor tissue is positioned in its place and then sutured. PKP procedure is performed on an out-patient basis which means that you may go home shortly after the surgery.
What are Punctal Plugs?

If non-surgical treatment options fail to provide relief from Dry Eyes then Punctal Plugs are used for the treatment of Dry Eyes as they help the tears to remain on surface of the eye for a much longer period of time. A Punctual plug is a small sterile device that is inserted into one of the small openings (also called punctal) of tear drainage ducts that are located in the inner corner of both upper and lower eyelids. During the procedure, these small openings are plugged with punctal plugs and the tears are unable to drain away from the eyes through the tear drainage ducts. As a result, the tear film stays on the surface of the eye for a longer period of time thus giving relief from symptoms of dry eyes.These tears simply evaporate from the surface of the eye without any symptom but if these plugs cause the eyes to “water” then one or more plugs may also be removed.
