Corneal abrasion

If you suffer from a scratch or an injury to the surface of your eye, don’t rub your eye or touch your cornea.

If a foreign object is embedded in your cornea, do not attempt to remove it. Go directly to the emergency ward at your nearest hospital or see an ophthalmologist. It’s important to seek quick treatment to avoid potentially serious complications, such as an infection, a corneal ulcer or corneal erosion.

Tarsorrhaphy is a surgical procedure that is sometimes performed on patients with corneal exposure or abrasions. The eyelids are partially sewn together to narrow the opening and protect the cornea until healing is complete.

Corneal dystrophy

Treatment may include:

Lubricating eye drops and ointments : if symptoms are mild

: if symptoms are mild Glaucoma eye drops : used to reduce the pressure inside the eye (intraocular pressure)

: used to reduce the pressure inside the eye (intraocular pressure) Temporary eye patch or ‘bandage’ contact lenses : to protect the cornea, increase comfort and facilitate healing

: to protect the cornea, increase comfort and facilitate healing Excimer laser therapy : can remove abnormalities from the cornea’s surface if symptoms persist

: can remove abnormalities from the cornea’s surface if symptoms persist Corneal transplantation: only in the most severe cases that don’t respond to other treatment

Recurrent corneal erosion

Treatment may include:

Topical lubricant : This treatment aims to help your epithelial cells heal and regenerate properly.

Antibiotic drops : Depending on the extent of your condition, your ophthalmologist may prescribe antibiotic drops and suggest the short-term use of a therapeutic contact lens, known as a ‘bandage’ contact lens (see below).

: Depending on the extent of your condition, your ophthalmologist may prescribe antibiotic drops and suggest the short-term use of a therapeutic contact lens, known as a ‘bandage’ contact lens (see below). ‘Bandage’ contact lens : These are soft, therapeutic lenses that provide oxygen to the cornea to reduce the risk of corneal hypoxia (insufficient supply of oxygen) and oedema (fluid accumulation). They can also decrease pain and help with the administration of eye drops.

Phototherapeutic keratectomy (PTK): This surface laser treatment may be recommended if your episodes worsen or become more frequent.

Corneal ulcer

Treatment will depend on the severity and type of corneal ulcer and usually involves antibiotic eyedrops or ointment in the first instance. If the ulceration is in the centre of your eye, it may take longer to recover. An anti-fungal agent may be necessary if the ulcer was caused by a tree branch or dirt.

Corneal transplantation is reserved for severe cases that have failed to respond to other treatments.

Keratitis

Infectious keratitis requires urgent attention.

There are a number of ways to treat keratitis, depending on the cause. Your ophthalmologist will typically prescribe antibacterial, antifungal or antiviral eye drops or ointments to treat the infection.

Prescription eye medication, oral medication or, in some cases, intravenous therapy may be used for more severe cases.

Ocular herpes

While it’s not possible to cure ocular herpes, there are a number of treatments which may help manage or control the condition.
