Corneal Surgery

Corneal Cross Linking (Keratoconus treatment)

Corneal Surgery

Corneal cross-linking uses a laser and eye drops to promote “cross-linking” or strengthening of the collagen fibers that make up the cornea. This treatment may flatten or stiffen the cornea, preventing further protrusion.

Corneal Transplant

A corneal transplant replaces a damaged cornea with a donor cornea.

The cornea is the clear front window of the eye.  Light is passed through the cornea so we can see.

Due to injury, cornea may become swollen or scarred resulting in scattering of light, glare and distortion of vision.

Corneal Surgery

Corneal graft is often offered to patients with keratoconus, hereditary corneal failure, scarring after infection or injury, corneal failure after other eye surgery.
 

The surgery is often done as a day surgery procedure. The tissue for the corneal transplant will come from a person (donor) who has recently died and who had agreed to donate their tissue. The donated cornea is processed and tested by a local eye bank for its safety.
 

Penetrating Keratoplasty is the most common type of corneal transplant. During this procedure, a small round piece of cornea is removed and the donated cornea is sewed into the opening of cornea.
 

A newer technique called lamellar keratoplasty may be used for some patients. During this procedure, only the inner or outer layers of the cornea are replaced, rather than all the layers. This technique can lead to faster recovery and fewer complications.

Foreign Body Removal

Any material such as dust, sand or particles that gets into the eye is called a foreign body.

Some of the foreign bodies only stick to the front of the eye or get trapped under one of the eyelids, but do not enter the eye, they are the superficial foreign bodies. Some of them penetrate deeper through the layer of the eyes and enter the eye, they are the penetrating foreign bodies.
 

For superficial foreign bodies, they can be removed using a cotton bud, although occasionally a small needle may be required to lift any embedded particles from the eye. This is carried out with local anaesthetic drops and does not hurt.
 

For deep penetrating foreign bodies, detailed assessment or scan will be needed to see how deep the objects have entered the eye. This can cause more serious damage to the eye and even result in blindness if no proper treatment is given.

Removal of Corneal Scar

Phototherapeutic keratectomy

Phototherapeutic keratectomy (PTK) uses a laser to remove tissue from the cornea.  This allows the removal of superficial corneal opacities and surface irregularities.
 

It can be used to remove corneal scars or opacities, or used to treat recurrent corneal erosion.

 

Diamond Burr

Diamond burr superficial keratectomy is an effective and safe method for removing corneal scar. It is also used for treating recurrent corneal erosions.
 

The procedure is fast and can be done in the clinic using topical anesthesia only.
