Specialty Contact Lens Exam

Overview

Specialty Contact Lens Exam

On occasion, soft contact lenses may not be the most appropriate option or may not be the solution to allow for the best vision correction or your eye health. Hard-to-fit contact lenses or specialty contact lenses come in many different materials, sizes, shapes, colors, and more for a variety of conditions. Some conditions treated with hardto-fit contact lenses may be as follows:

  • Keratoconus
  • Pellucid Marginal Degeneration
  • Keratoglobus
  • Post-LASIK or other refractive surgery complications
  • Corneal Scarring (conditions such as: Stevens-Johnson Syndrome, cicatricial pemphigoid, keratitis, burn victims, and many others)
  • Severe Dry Eyes
  • High Corneal Astigmatism or Abnormal/Irregular Astigmatism
  • Giant Papillary Conjunctivitis


Your eye care provider will work with you to determine the best option(s) available to ensure the best eye health and visual outcome.

Eye Conditions

Keratoconus & Specialty Contact Lenses

Keratoconus is a eye disease where the cornea (front surface of the eye) thins and bulges forward into a cone shape. Soft contact lenses often cause discomfort and distortion because the lenses do not properly correct the patient’s vision. Rigid gas permeable lenses or other specialty contact lens options are instead recommended, as these lenses act as the cornea or the front surface of the eye due to the hard surface. It is also thought that some specialty lenses may slow the progression of the disease.

Pellucid Marginal Degeneration & Specialty Contact Lenses

Pellucid Marginal Degeneration (PMD) is a non-inflammatory, non-hereditary disease of the front surface of the where the cornea (front surface of the eye) becomes thinner in the peripheral aspect next to the limbus (white part of the eye). Rigid gas permeable or other specialty contact lenses are the best option due to often irregular astigmatism (multiple curvatures of the eye with fluctuating/changing power) making it challenging for the patient to see without distortion, double vision, ghosting, or haloes in the patient’s vision.

Keratoglobus & Specialty Contact Lenses

Keratoglobus is a non-inflammatory corneal (front surface of the eye) condition where the cornea becomes thinner and protrudes. Specialty contact lenses are often recommended to improve the visual outcomes for patients due to distortion, ghosting, and other visual symptoms.

Post-LASIK/Refractive Surgery & Specialty Contact Lense

Refractive surgery often leads to improvement of the patient’s vision; however, there are rare cases where patients experience complications. Patients may experience glare at night or corneal ectasias (thinning of the front surface of the eye) causing visual distortions or even double vision. Specialty contact lenses are often recommended in these cases, as soft contact lenses may or may not improve those visual symptoms.

Corneal Scarring & Specialty Contact Lenses

Corneal scarring can occur from a host of insults that may include: burns, viral sources (shingles, simplex virus), bacterial infection, autoimmune response, or other sources. Specialty contact lenses often protect the front surface of the eye while also improving visual comfort and clarity.

Moderate/Severe Dry Eye & Specialty Contact Lenses

Moderate/Severe dry eye can cause symptoms such as: burning, redness, irritation, and a foreign body (gritty) feeling. Dry eye syndrome can also cause decreased vision or blurry vision at all distances. Many patients often report that contact lenses worsen their symptoms; therefore, it is important to determine the underlying cause of your dry eye. There are many options to improve your dry eye syndrome. After dry eye syndrome is addressed, specialty contact lenses may be a solution or part of the solution to address your concerns. Talk with your eye doctor to determine if this is right for you.

High Corneal Astigmatism & Specialty Contact Lenses

Corneal astigmatism is where the front surface of the eye has a significant curvature or steepness. Given this curvature difference, contact lenses often rotate causing vision distortion or blurry vision. Your eye care provider can offer multiple options to improve your vision that may not be readily available in traditional or common brands offered.

Giant Papillary Conjunctivitis & Specialty Contact Lenses

Giant papillary conjunctivitis (GPC) is a condition where the inner part of the eyelid surface (palpebral conjunctiva) becomes swollen with little bumps called papillae. This condition worsens or is caused due to the accumulation of protein or deposits on contact lenses (cloudy white deposits). To solve this, your eye doctor may recommend a new solution, daily contact lens options, or specialty contact lenses. In moderate/severe cases, your eye doctor may recommend not to wear contact lenses for a certain period while your eye doctor prescribes eye drops to improve your signs/symptoms.

What are some types of specialty contact lenses?

Rigid Gas Permeable Contacts

Rigid gas permeable contact lenses are made from a durable material that acts as the cornea (or front surface of the eye). These lenses offer superior optics, less flexure in the lens itself, and reduces protein buildup on the lens. The lenses are much smaller than most soft contact lenses with a longer lifespan of annual replacement.

Scleral Contact Lenses

Scleral contact lenses vault the entire front surface of the cornea without touching it at all. The edge of the contact lens sits on the conjunctiva/sclera (white part of the eye entirely). These lenses are often offered for patients with dry eye syndrome, advanced keratoconus or corneal ectasias (thinning of front surface of the eye). These contact lenses are filled with an approved preservative-free saline solution, which helps hydrate and lubricate the eye with contact lens wear. Discuss this with your eye doctor to determine if this option is right for you!

Hybrid Contact Lenses

Hybrid lenses offer a durable center allowing excellent clarity visually while offering a soft skirt (or peripheral design) allowing for maximal comfort for the wearer.

Prosthetic Soft Contact Lenses

Prosthetic soft contact lenses offer varying sizes, colors, pupil designs, and other features to cloak or cover up cosmetic variabilities for patients with eye diseases. For example, a patient with significant scarring may be self-conscious regarding a white spot on the front surface of the eye. A prosthetic soft contact lens may be used to match the non-affected eye to make the patient less selfconscious about the appearance of the affected eye.

How long does my prescription last for?

Two years unless otherwise noted on your prescription.

How often should I replace my rigid gas permeable contact lenses?

The Food, Drug Administration recommends replacing annually but checking with your eye care provider for any other recommendations.

What are warranted versus non-warranted rigid gas permeable lenses?

Warranted lenses allow your eye doctor to make changes to your RGPs for an allotted period (usually 90-120 days). After that time, you will incur additional fees for any changes to the lens. Non-warranted lenses may be ordered after you have a finalized set of contact lenses for a reduced cost (approximately 30% less).

How long does your eye doctor have to make changes to my warranted contact lenses?

We have approximately 90-120 days (pending on the manufacturer) from the time of order to make any changes to the contact lenses at no cost. After this time, we can make changes only with additional fees. It is important to make all scheduled visits.

Are rigid gas permeable contact lenses more or less comfortable than soft contact lenses?

First, RGPs are often uncomfortable and cause tearing, a foreign body sensation, and redness during the first week of wear. After that time, those symptoms subside, and patients begin enjoying their clear, comfortable vision.

What happens if I decide that rigid gas permeable contact lenses are not for me?
  • You must return your rigid gas permeable contact lenses to the office. The office must return those to the manufacturer to receive credit.
  • Professional contact lens evaluation fees are non-refundable.
