Rarely, after lasik, a white spot on the eye forms, causing light sensitivity and discomfort. This represents inflammation which is associated with gram-positive bacteria, most likely Staphylococcus. It resolves within 1 week, with steroid and antibiotic eye drops, with minimal impact on vision.

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””
We have to treat this aggressively with antibiotics, to prevent permanent vision loss and scarring.
Contact lens overwear
Symptoms include red eye, foreign body sensation, pain, sensitivity to light, watering, and blurred vision.
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”
Contact lens overwear
Corneal vascularization occurs when contact lenses do not allow your eyes to breathe normally. In order for your eyes to be healthy again, you must decrease contact lens wear time and/or change to a more oxygen permeable contact lens material.
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.
When Contact Lenses Cause Inflammation
Sometimes contact lenses can cause inflammation of the cornea, with an accompanying bacterial infection. The white dot shown on the cornea above is an infiltrate, caused by bacterial inflammation. Symptoms can range from mild discomfort, feeling like there’s something in your eye, tearing, and redness, to severe pain, light sensitivity, and decreased vision. Corneal infiltratesContinue reading “When Contact Lenses Cause Inflammation”
