Am I a Candidate for Specialty Contact Lenses?

Specialty contact lenses help people with hard-to-fit eyes. Hard-to-fit eyes refer to eye conditions that do not allow conventional contact lenses to fit properly. Specialty contacts are more comfortable for patients with such conditions to wear. They also help correct refraction errors resulting from the same conditions. Examples of specialty contact lenses are:

  • Scleral lenses.
  • Toric lenses.
  • Bifocal and multifocal lenses.
  • Hybrid lenses.
  • Rigid gas permeable lenses.


 

Who Is a Good Candidate?


Whatever your condition is, you must first start with an eye exam. The exam will establish whether you need specialty contact lenses. Some specialty contact lenses can serve several conditions. However, other contact lenses meet the wearer's specific eye condition. These conditions include:

  • Post corneal transplant surgery.
  • Astigmatism.
  • Progressive nearsightedness.
  • Pellucid marginal degeneration.
  • Giant papillary conjunctivitis (GPC).
  • Keratoconus.
  • Corneal scars.
  • Discomfort with current lenses.
  • Severe dry eye.


 

Post Corneal Transplant Surgery


The optimal choice for this post-surgery condition is scleral lenses. This is because they cover the entire cornea without applying pressure on it. They allow the eye to remain hydrated and are larger than conventional lenses — hence, they do not shift or move around the eye. This ensures ultimate healing, as there is no risk of irritation or abrasion.


 

Astigmatism


Toric lenses are specially made for astigmatism because they can stay in place on the eye. Toric lenses are soft lenses made from hydrogel or silicone hydrogel. Thus, they can be made specifically for the patient’s eye. If they do not fit, there is the option of using rigid gas permeable lenses. For high astigmatism, doctors also use multifocal lenses.


 

Progressiveness Nearsightedness


Multifocal lenses help correct this condition. Patients wear these in cases where orthokeratology lenses cannot apply. One such case is where the prescription is too high.


 

Pellucid Marginal Degradation


Treatment for this condition uses a special kind of toric lenses — the bitoric rigid gas permeable lenses. They have a toric power on the front surface. They also have a toric curvature on the back surface that conforms to the patient’s cornea.


 

Giant Papillary Conjunctivitis (GPC)


This condition worsens with the buildup of protein deposits. Thus, this calls for the use of rigid gas permeable lenses. They limit the buildup, reducing the symptoms of GPC.


 

Corneal Scars 


This condition calls for the use of special scleral, rigid gas permeable lenses. This is because they prevent the risk of further scarring while hydrating the eye. They also provide a clear vision for the patient.


 

Discomfort With Current Lenses


If you are uncomfortable with your current soft or hard lenses, you can try the hybrid lenses. They have a gas-permeable center with a soft outer ring. The soft outer ring makes them more comfortable than traditional gas-permeable lenses. However, they have the clarity of gas-permeable lenses.


 

Severe Dry Eyes


This condition benefits from the use of rigid gas permeable lenses. This is because they allow oxygen and keep the eye hydrated. Scleral lenses are also ideal for this condition.
