Hard-to-Fit Eyes Require Specialty Contact Lenses
There is no one-size-fits-all approach when it comes to contact lenses, and some eyes are more difficult to fit than others. The expert team at Eye Rx specializes in fitting contacts for hard-to-fit eyes, particularly patients with keratoconus.
What is Keratoconus?
Keratoconus is a progressive eye disease, which causes the usually round cornea to thin and bulge, creating a cone-like shape. This cone shape distorts the light entering the eye, impacting your vision. As the cornea’s shape becomes increasingly irregular patients develop progressive myopia (nearsightedness) and irregular astigmatism, further compounding vision problems.
Mild keratoconus can be treated using eyeglasses or regular soft contact lenses, but as the condition progresses, you may require scleral, gas permeable, or hybrid contact lenses.
We Specialize in Hard-to-Fit Eyes
Both Dr. Teller and Dr. Lobaugh have extensive experience helping hard-to-fit patients find the right contact lenses to suit their needs and specialize in helping patients with keratoconus. Both optometrists are also able to help fit contacts for patients with astigmatism, dry eyes, and giant papillary conjunctivitis, as well as patients who have undergone refractive surgery.
The key to selecting the right style of lenses for hard-to-fit eyes is accurate measurements, which we get using a variety of instruments and tests including, corneal topography, Wavefront, and anterior segment optical coherence tomography.
Eye Rx Welcomes EyePrintPro™
Eye Rx is proud to add EyePrintPro™ lenses to our brand portfolio. Similar to scleral lenses in how they sit on the eye, but more exact in their fit, EyePrintPro™ uses 3D printing and scanning technology for a more precise and exact fit. Ask if EyePrintPro™ lenses could be right for you.
Specialty Lenses to Suit Your Needs
Scleral contact lenses are made of a rigid, gas-permeable material, and get their name because they vault over your cornea and rest on your sclera (the white of your eye). Scleral contact lenses are specifically designed to accommodate irregularly shaped corneas and are typically prescribed to patients with keratoconus or astigmatism.
Scleral contact lenses may also be prescribed to patients who have recently undergone a corneal transplant. The scleral lens acts as a bandage, allowing the patient to see clearly while their cornea heals.
EyePrintPRO Lenses, Exclusively at Eye Rx
EyePrintPRO contact lenses are prosthetic scleral shells that cover your sclera and improve your vision by creating a smooth refractive surface for your eye. These custom contacts are made using the EyePrint Impression process, which takes a mold of the outer surface of your eye.
These lenses are individually tailored to each wearer, offering clear vision and comfort for patients with irregular corneas.
Dr. Teller is currently the only Certified EyePrint Practitioner in the Metropolitan D.C. Area.
Hybrid contact lenses consist of a rigid, gas-permeable central zone, which is surrounded by a soft zone made of hydrogel or silicone hydrogel. This unique combination of materials allows hybrid contacts to provide patients with the sharp vision of rigid lenses and the comfort of soft lenses.
Hybrid lenses are particularly popular amongst athletes since their large diameter, and thin edges make them less prone to dislodging during sports and other high energy activities.
Orthokeratology contact lenses or Corneal Refractive Therapy (CRT) lenses are a type of rigid, gas-permeable lens that is designed to be worn overnight. As you sleep, the lenses gently reshape your corneas, temporarily correcting myopia, hyperopia, and astigmatism and providing you with clear, crisp vision the next day.
However, the lenses are only able to reshape your cornea temporarily, so they will need to be worn every night, or your eyes will revert to their original prescription.
Toric contact lenses are designed specifically for patients with astigmatism. While standard spherical lenses are made using only one prescription, toric lenses feature different prescriptions along the vertical and horizontal axes.
In order to provide patients with a clear vision, toric lenses must remain orientated a certain way, which is why they are weighted to prevent rotation.
Multifocal contact lenses are made with two or more prescriptions on the same lens and are typically prescribed to patients with presbyopia. Presbyopia impacts our ability to focus clearly on near objects. Many of us will develop presbyopia as we age, and can be corrected with multifocal glasses or contact lenses.
Multifocal contact lenses allow you to transition your gaze between distant and near objects without needing to switch between different pairs of glasses or contact lenses. These contact lenses can be madeeither using concentric rings of distance and near powers (similar to bifocal glasses) or may be aspheric, which allow you to smoothly transition between prescriptions.
