Specialty Contact Lenses
Contact lenses are not an easy solution for every person suffering with vision problems. Some eye conditions make wearing contacts a difficult proposition. However, it does not rule out wearing contact lenses altogether. It just means patients need to discuss options with their eye care providers and obtain specialized hard-to-fit contacts with their specific vision problems.
Reasons for Hard-to-Fit Contact Lenses
Astigmatism developes when the front of the eye curves into a bulge or oval shape. It causes blurred vision and can be difficult to correct because regular contacts cannot account for the bulging.
When eyes become excessively dry, it leads to irritation, burning, redness, and blurred vision. Contact lenses can exacerbate these conditions by making it feel like a foreign object is stuck in your eye.
This form of conjunctivitis is caused by inflammation on the inner surface of the eyelid. Protein buildup on the contact lenses can make this condition worse.
This is an uncommon condition that causes major discomfort when wearing contacts. Keratoconus happens when the cornea becomes thinner and allows the eye to bulge forward. The bulge forms into a cone shape.
Eyes tend to have a tougher time focusing on close objects as they age. This condition is known as presbyopia. It typically affects people aged 40 or older.

Solutions for Hard-to-Fit Contact Lenses
Gas Permeable Lenses
Gas permeable lenses are a good solution for patients who suffer from GPC or Keratoconus. A GP lens will limit protein deposits from accumulating which will reduce GPC symptoms. It is also effective in containing corneal bulging and relieving pressure on the tissue for a Keratoconus sufferer.
Toric lenses are useful for correcting astigmatism. Since the lens needs to align with the bulge it is correcting, toric lenses must not rotate in order to fit on the eye.
They are typically custom made to correct a specific astigmatism. For that reason, this type of lens takes longer to make and costs more than a traditional contact lens.
Bifocal and Multifocal lenses
Bifocal and multifocal lenses can help remedy presbyopia. Monovision lenses are another option for presbyopia. This type of lenses can have one fitted for distance vision and the other for seeing close objects.
Many patients with vision problems heartily embrace the idea of enjoying vision correction without having to wear eyeglasses or contact lenses. Not all of these patients, however, are good candidates for PRK or Lasik surgery, the two standard surgeries used to alter the way the cornea of the eye refracts light. If that describes you, don’t fret – because here at Lake Lanier Eye Care, we offer an advanced corneal reshaping technique known as orthokeratology, or Ortho-K. This non-surgical technique can produce changes to the way your cornea refracts light.
To understand the benefits of Ortho-K, let us first consider how the cornea works. The cornea is a transparent, spherical bulge that sites over the lens of your eye. In addition to protecting the inner parts of the eye, the cornea also performs some lens-like tasks of its own. The shape of the cornea causes incoming light rays to be refracted, or bent, in such a way that the lens can focus them into a clear, sharp, image to pass on to the retina and optic nerve. Ultimately, the optic nerve transmits the image to your brain.
Deformations in the shape of the cornea cause refraction to go wrong in various ways, producing the fuzzy images characteristic of nearsightedness, farsightedness, and astigmatism. Glasses and contact lenses are curved to “pre-refract” incoming light to compensate for your personal degree of corneal deformation. Laser surgery actually corrects the shape of the cornea itself, eliminating most of all of the visual errors that might otherwise call for corrective lenses.
While you might leap at the thought of permanently correcting vision problems, laser surgery isn’t always the best eye care option. For instance, if you suffer from thin corneas, untreated cataracts, diabetes, certain autoimmune diseases, or a corneal disease called Keratoconus, you should avoid laser eye surgery.
Some of our patients simply don’t like the idea of any kind of surgery, or they want a reversible procedure. Orthokeratology may be an ideal choice for these individuals. Dr. Bordner will map the shape of your corneas precisely and then fabricate special contact lenses. Unlike standard contacts, you’ll wear these lenses at night. The lenses preform a subtle corneal reshaping while you sleep, meaning that you can take them out the next morning and enjoy perfect or near-perfect vision.
Ortho-K can help you see clearly for one or two days at a time, possibly even longer. By wearing them regularly at night, you can maintain your clarity of vision for as long as you decide to continue using them. If you decide to use another form of vision correction, simply stop using the Ortho-K lenses and your corneas will assume their previous shape once again. Talk to our knowledgeable staff to see whether Ortho-K makes sense for you.
