If you've heard that you might be "hard to fit" for contact lenses, you're probably wondering whether you'll be able to get the glasses-free vision correction you want, or what kinds of options might make it possible. Check out these answers to frequently asked questions about hard to fit contacts from Primary Eyecare and Optical of Meridian.
"Hard to fit" means that ordinary soft contact lenses may be inadequate for your needs. This incompatibility may be due to either complex corrective issues or underlying health challenges that affect what kinds of lenses you can wear.
Some vision problems require more correction than you can get from standard soft contacts. That's partly because soft contacts conform to the corneal surface, making them incapable of correcting conditions such as astigmatism and keratoconus. Complications such as presbyopia (which requires correction for both near and far viewing) may also be beyond the scope of ordinary contacts.
Dry eye can be made worse by contact lenses that aren't optimized to retain moisture. Ordinary soft contacts also tend to collect debris. This debris can cause inflammation in people prone to a condition called giant papillary conjunctivitis (GPC).
Our optometrist always administers a contact lens exam as part of the fitting process. By understanding your specific corrective needs and wellness considerations, we can determine whether you have "hard to fit" eyes. From there we can prescribe specialized contact lenses suited to your condition or needs.
GP (gas permeable) materials are often best for difficult corrective prescriptions because they maintain their own shape instead of conforming to (possibly irregular) corneal contours. They’re also good for correcting presbyopia. Specific shapes and configurations, such as toric or scleral contacts, are recommended for corneal irregularities such as astigmatism and keratoconus.
If you have dry eyes, our optometrist may recommend contact lenses made of materials such as hydrogel to ensure that your eyes remain moist beneath the lenses. Scleral contacts, which cover the entire cornea, can also help retain eye moisture. GP lenses collect less debris than soft lenses for GPC sufferers.
