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.
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”
We have to treat this aggressively with antibiotics, to prevent permanent vision loss and scarring.
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”
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”
Did you know that a corneal ulcer can cause permanent scarring? At the front of the eye is a clear layer of tissue called the cornea. The cornea allows light to enter the eye. The cornea is bathed in tears, which provide the natural defense against bacteria and viruses. A corneal ulcer is an openContinue reading “When Contact Lenses Cause Scarring”
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.
