Are Daily Disposable Contacts Worth the Extra Cost?

Yes!  Because you can avoid a corneal ulcer, which is caused by a bacterial infection of the cornea.  Extending the life of your weekly and monthly lenses, and wearing them for too many hours are often the culprits.  A corneal ulcer is a painful open sore on the clear front surface of the eye thatContinue reading “Are Daily Disposable Contacts Worth the Extra Cost?”

“Something in my Eye”

White blood cells can penetrate into the corneal tissue as part of the body’s inflammatory response to the presence of bacterial toxins. A corneal ulcer is an epithelial defect with underlying inflammation and involves much more pain, redness, and vision loss. An ulcer is more serious and requires immediate, aggressive treatment with antibiotics taken everyContinue reading ““Something in my Eye””

Blood vessels on the Eye

Corneal pannus is the growth of blood vessels onto the cornea.   A common cause of corneal pannus is contact lens wear, particularly if the contacts aren’t fitted properly.  In that case the contacts should be refitted, or perhaps discontinued. Sometimes pannus is a result of past infection such as herpes simplex. Sometimes corneal pannus is notContinue reading “Blood vessels on the Eye”

Corneal Pannus

Corneal pannus is the growth of fine blood vessels onto the clear corneal surface. The treatment depends on the cause. For instance, a common cause of corneal pannus is a poorly fit contact lens.   Also, pannus can occur if the contact lens does not allow enough oxygen to the eye.  Contact lens may need toContinue reading “Corneal Pannus”

My eye hurts

Subepithelial infiltrates (SEI). SEIs generally occur after viral keratitis, but are also found in blepharitis and contact lens-related hypersensitivity.   White blood cells from the limbal vasculature are drawn into the avascular cornea. What is Inflammation? Inflammation is the body’s response to protect tissues and organs. It is an efficient response caused by injury, infection, autoimmuneContinue reading “My eye hurts”

When your eyes don’t breathe

When the cornea does not get enough oxygen, there is corneal hypoxia.   This is the most common complication of contact lens wear, especially extended-wear lenses. The cornea has no blood supply of its own, so it gets oxygen only from tears and directly from the atmosphere.  Sleeping in or overwearing your contact lenses reduces theContinue reading “When your eyes don’t breathe”

When Contact Lenses Cause Problems

Did you know that sleeping in your contact lenses, over-wearing your contact lens, and not cleaning/disinfecting your contact lenses properly can cause a corneal infiltrate? Bacterial exotoxins are responsible for whitish/gray anterior stromal infiltrates in the cornea.  They are usually round, well defined, and small, ranging in size from 0.1mm to 2.0mm.  There are oftenContinue reading “When Contact Lenses Cause Problems”

Contact Lenses Cause a Scar

Did you know that if you over-wear your contact lenses and develop a bacterial infection, a corneal scar can develop?    This can permanently affect your vision.

Severe Dry Eye

Chronic dry eye can be caused by inflammation which affects your eyes’ ability to produce tears.   Dry eyes cause discomfort, burning, stinging, eye fatigue, sensitivity to light, eye redness, a sensation of something in your eye, and tearing.    Only a thorough physical examination can determine the severity of your dry eye, with appropriate treatment.    IfContinue reading “Severe Dry Eye”
