Contact Lenses For The Hard-To-Fit-Patient
Challenges such as astigmatism, presbyopia, keratoconus and dry eyes needn’t be a barrier to contact lens wear, but they do require more time and patience.

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.
- 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. Read more
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.
Toric Contacts For Astigmatism
Astigmatism is a condition that causes blurred vision (in some cases double vision) because rather than being round, the front of the eye (the cornea) has two curves instead of one, therefore, having two focal points instead of one.
This makes it hard for traditional contact lenses to fit and therefore requires specialized contact lenses such as toric lenses or rigid gas permeable lenses (RGPs).
Toric contact lenses are designed to correct astigmatism and custom made to fit the eye of the patient.
Most are made of soft material designed to stay in place on the eye, however in some cases, when the rotation of the lens (due to blinking and eye movement) can’t be stopped, gas permeable lenses might be tried.
Due to the customization and more complicated fitting process required for these lenses, they are more expensive and take more time for the contact lens laboratory to make than traditional lenses.
