It is not uncommon for patients to have difficulty wearing contact lenses for a number of reasons. Due to the individual eye shape, certain conditions or impairments or the aftermath of surgery, some patients are considered to be “hard to fit” as contact lens wearers.
For hard to fit patients that prefer to wear contact lenses however, there are options available that can provide comfortable and effective contact lens wear. This will require a specialized fitting with an eye doctor that is an expert that knows your condition and the various products available to find the right match for your specific condition. You may be considered a hard to fit contact lens candidate if you have one of the following conditions:
- Dry Eyes
- Giant Papillary Conjunctivitis (GPC)
- Pellucid Marginal Degeneration
- Post-LASIK or other refractive surgery
- Presbyopia (reduced near vision common in individuals aged 40 and over).
- Corneal Scarring
Dry Eyes and Contact Lenses
Dry Eye Syndrome causes your eyes to feel dry, gritty, burning, red, and irritated. Dry Eye Syndrome can also cause blurred vision. Often these symptoms can sometimes worsen by the use of contacts. In fact, many people who do not normally suffer from chronic dry eyes, will experience some of these symptoms as a result of contact lens wear.
First of all, if you have chronic dry eyes, you should see your eye doctor for treatment and relief before you think about contact lenses. Once your dry eyes are treated, it is safe to try contacts and there are a number of options that can be considered.
Many brands of soft contacts and products such as disinfectant and cleansing solutions are made with ingredients that are designed to be more comfortable for individuals with dry eyes. Your eye doctor will be able to recommend some of these brands and products to you. Alternatively, gas permeable (GP) or rigid gas permeable (RGP) lenses are made with a hard material that in some cases does not dry out like soft lenses and they are able to hold a certain amount of moisture beneath the lens to keep the eye from drying out. Gas permeable lenses are a very good option and can be quite comfortable for individuals with dry eyes.
Additionally, your doctor might recommend a specific wearing schedule such as limiting the time you wear your contacts throughout the day or replacing your contacts on a more frequent basis.

Giant Papillary Conjunctivitis (GPC) and Contact Lenses
GPC is a type of conjunctivitis in which the inner surface of the eyelid becomes swollen. The condition can be caused or worsened by a buildup of protein deposits on contact lenses. Your eye doctor may either recommend daily disposable lenses or RGP lenses (which are not water based) and therefore do not have a tendency for protein buildup. Your doctor may also prescribe medicated eye drops and require you to stop the use of contact lenses until the symptoms improve.

Rigid Gas Permeable (RGP) Lenses for Keratoconus
Keratoconus is a condition in which the cornea thins and bulges forward into a cone shape. Traditional contact lenses may cause some discomfort in these patients and the vision may still be blurry therefore RGPs are often used for treatment for mild, moderate, and some severe cases. Rigid gas permeable lenses may help to slow down the cone shape from worsening in some cases. Further, RGPs are able to assist in vision correction for keratoconus which is often not possible with soft contacts or even eyeglasses.
Post-LASIK or Vision Correction (Refractive) Surgery
While LASIK surgery has a very high success rate, there are vision complications and symptoms that sometimes remain. Night vision after LASIK, in particular, can sometimes give you side effects such as glare or halos around lights. RGPs are often effective in helping with these side effects and restoring clear vision.
