One out of every four people in the world suffers from one form of allergy or the other. This number is even higher when it comes to people who have keratoconus, a very common degenerative disease of cornea leading to slowly progressive deformation and thinning of the corneal tissue. The cause of this degenerative disease is largely unknown, but there are many factors that have been implicated, and ocular allergy is one of them. Almost half of all contact lenses wearers have ocular allergies and the number is even higher with people suffering from keratoconus. For this reason, it is a constant battle for practitioners to help people with such allergies to wear contact lenses comfortability. With this in mind, it is even more important that if you wear daily disposable contact lenses, you wear the right ones for you.

In order to help patients in the most effective way, it is important that practitioners must be able to do a differential analysis between the real allergies and conditions related to contact lenses. Following four signs can help them make a correct diagnosis:

  • Persistent inching in the eyes even after the lenses have been removed
  • Discharge of string-like mucous
  • The constant false feeling of the contact lenses moving from their position
  • The presence of a papilla that is both superiorly and inferiorly

If the patient answers yes to any of the above four questions, their eyelids need to be inverted to be examined for the presence of giant papillae. This will confirm the allergy is related to the contact lens. If on the other hand the papillae is smaller and the itching is constant, the allergy may be a true allergy and not something that may be related to the contact lenses and would thus require a different line of treatment altogether.  

The Correct Lens Type

Practitioners recommend changing the lenses if the wearer suffers from allergies. Changing the material of the lens to low water- non-ionic material can help. These are Group 1 category lenses and help in minimizing allergy effects. Switching to Silicone Hydrogel lenses can also help to avoid discomfort as can starting to wear fresh daily wear lenses instead of extended wear options.

Patients must make it a practice to rinse the lenses with saline solution to avoid the contact of H2O2 with their eyes. Patanol is a prescribed topical agent that can also provide a lot of relief.

Oral Medications causing Dryness

A lot of patients are not aware that consuming medicines for seasonal or perineal allergies can also be the cause of dryness in the eyes. The ocular dryness is a side effect of a lot of oral medication, but here caution needs to be practiced as the need to consume these may be higher than the discomfort caused to the eyes.
