Corneal ulcer is an open wound on the corneal (also known as keratitis) usually caused by infections such as virus, bacteria or fungus.  This is serious condition because the ulcer can slowly get deeper into the eye and may result in a perforated cornea (hole).  This can lead to corneal scarring or even blindness if left untreated.

Risk Factors

• Contact lens wearers
• Dry eyes syndrome
• Eye injury (especially with organic material such as soil or leaf, rusty nail or rust)
• Poor eyelid function such as Bell’s palsy or stroke

Treatment

Any foreign body material will need to be removed by your doctor.  All corneal ulcers need to be treated with medication to kill the infection. The medication may be in the form of eyedrops, eye ointment or oral medication and your doctor will advise you on the frequency and how to apply. 

Prevention Do’s and Don’t’s

DO clean their lenses every day with appropriate cleansing solutions

DO wear protective eye wear or goggles when using cutting or welding tools

DO apply lubricant eyedrops when your eyes feel dry

DO remove your contact lenses if you feel discomfort to rest your eyes

DO NOT over wear your contact lenses and remove them 1-2 hours before sleep to let your eyes breathe

DO NOT swim or use a steam room with contact lenses

DO NOT wear contact lenses overnight

DO NOT use contact lenses beyond their recommended duration (daily, fortnightly or monthly lenses)
