Frequently Asked Questions..
Contact lens wear, even with the best care and routine compliance, increases the chances of getting eye infections and diseases. All of which are very painful and can lead to corneal scarring causing decreased vision and in some cases even blindness. This is why at Spanish Oaks Eyecare we recommend dailies first. You wear each pair once, then throw it away and put on a fresh pair the next time you wear your contacts. They are great for people with dry eyes, allergy eyes, contact lens intolerance, non compliant patients who don’t want to keep track of when to change their lenses, swimmers, new wearers and pretty much everyone! You will love the feeling of a new pair on your eyes every day.
- Normal Eye Upper Left: Cornea is clear without any grayish spots (infiltrates) or staining. Upper Right: Tissue on under side of upper eye lid (palpebral conjunctiva) is normal and is smooth, pinkish, and without bumps (papillae) associated with giant papillary conjunctivitis (GPC). Lower Left: Reflection on cornea demonstrates a normal epithelium without distortion. Lower Right: Corneal Topography Reflections on cornea demonstrate a normal epithelium without distortion.
- Corneal Staining due to allergic sensitivity to disinfecting solution Corneal Staining with Sodium Fluorescein secondary to allergic sensitivity to multi purpose disinfecting solution. Note the pattern of staining (green spots) on the outer layer of the cornea (epithelium). These are damaged cells. This patient complains of discomfort and blurry vision. This condition will resolve and the staining will go away within a few weeks after changing to a different solution. If due to suspected sensitivity of solution, our treatment would be to discontinue contact lens wear until staining is gone, and then resume contact lens usage with Clear Care disinfectant.
- Corneal Infiltrates due to allergic sensitivity to disinfecting solution This is Corneal Infiltrative Keratitis secondary to allergic sensitivity to multi purpose disinfecting solution. Note the grayish spots on the cornea. This patient complains of discomfort and blurry vision. This condition will resolve after changing solution or discontinuing contacts. Sometimes it may takes weeks or months for this to resolve and for the cornea to become clear again. Treatment would be to discontinue contacts until resolved, and then change disinfecting solution. We may prescribe an antibiotic eye drop if epithelium is damaged.
- Giant Papillary Conjunctivitis (GPC)Is a slowly developing allergic reaction to soiled contact lenses which are used for more than recommended intervals. This is why disposable lenses were developed and why you are supposed to replace them on a frequent basis. This condition will resolve and the tissue (palpebral conjunctiva) will become smooth and pink again (see photo 1) if lenses are not worn or if this patient replaces their lenses more frequently as recommended by the FDA. This was very common 20 years when patients were using “traditional soft contact lenses”. which have been replaced by disposables. The intent of disposable soft lenses was to reduce the incidence of GPC. However, we are seeing more GPC because patients are using disposable contact lenses beyond the recommended replacement intervals. GPC is a valid argument for prescribing single use 1-Day Disposable Lenses, or reinforcing to patients to replace their lenses frequently, and not overuse each pair.
- Corneal Abrasion Due to Foreign BodyParticulate matter which became lodged in the eye or under the eyelid, and subsequently scratched the cornea. It could be sand, metal, or a piece of sheetrock. The Doctor usually diagnoses it based upon the activities the patient was involved prior to the complaint. Something got in their eye, and became lodged between their contact lens and the cornea, or became attached to the underside of the upper eye lid and repetively scratched the cornea with each blink. In the photo below, the vertical, and up and down orientation of the scratches are classic for this diagnosis. The greenish appearance of the photo is due to sodium fluorescein which we instill to help diagnose such problems. This patient is in pain and requires an antibiotic as prophylaxis to prevent infection of the corneal epithelial wound or damage. In more severe cases, such as a paper cut, we would have them wear a contact lens as a “bandage lens” until the wound heals. After that we would inform them of the possibility and symptoms of a “recurrent corneal erosion” which may occur after a corneal injury, and necessitate further treatment.
A corneal ulcer is an injury to the epithelium of the cornea and is considered an ocular emergency. A corneal ulcer causes pain, discomfort and, in many cases, blurry vision. The reason patients consult us is usually because of the pain. The most common reason that patients present with a corneal ulcer is that they slept in their contacts. The treatment for a corneal ulcer is to discontinue contact lens usage, and prescribe an antibiotic. The patient must be compliant and not use contacts on the affected eye for up to 3-4 weeks. The highly magnified photo below is from a biomicroscope that we use to diagnose such problems. Note the round spot, which is the marginal corneal ulcer.
Neovascularization of the Cornea.New blood vessel in-growth to the cornea in response to using lower oxygen contact lenses. The cornea receives its oxygen supply from the air in front of the cornea. When it is covered by a contact lens the oxygen supply is reduced and the cornea responds by suppying new (neo) vessels to deliver more oxygen. This occurs more often when patients sleep in contacts and is why silicone hydrogel lenses are better because the are more oxygen permeable.
Corneal Foreign Body, Metal Note the brown spot on the right side peripheral cornea. This usually occurs as a result of grinding, welding, and hammering metal. The metal particle has become brown due to it rusting and needs to be removed because it is toxic to the cornea.

So we can see parts of your retina that aren’t normally visible to look for asymptomatic, painless, sneaky pathology like tumors, retinal holes, tears and detachments, signs of diabetic or hypertensive retinopathy and get better views of your macula and optic nerve to evaluate for macular degeneration and glaucoma. All types of pathology can be found in your eyes including but not limited to diabetes, high blood pressure, high cholesterol, impending stroke, HIV, cancer, and other issues associated with trauma or age.
Yes! The optomap is the preferred method if the photos are taken properly. Not only do the photos provide photo documentation but they also allow Dr. Miller to catch smaller holes or areas of bleeding that may otherwise be missed. It also side effects such as blurred vision or sensitivity to sunlight for hours afterwards. However dilation may still be needed in some cases if the pupil size is very small or during pediatric exams.
These drops are vasoconstrictors and only mask symptoms of conditions causing the problems, like redness, in the first place. Use them long enough and they will actually backfire on you. You should have an eye exam to evaluate what’s causing the redness, infection, allergies, dry eyes etc then treat that problem, not just the symptoms.
