How to take care Contact lens related allergies?

Contact lenses (CLs) provide safe and effective vision correction if adequate lenses’ care is ensured as recommended. However, CLs’ wearers may have risk of eye infections if they fail to clean, disinfect, and store their CLs as instructions given.


    Contacts are composed of hypoallergenic materials. This means the materials themselves do not usually cause an allergic reaction. Instead, what causes it is a buildup of contaminants on the contacts. However, in rare cases, people can develop allergies to the actual lenses.
    Your eyes produce a protein that is deposited on your contact lenses while being worn. The protein is broken down when the lenses are stored in the contact lens solution. Over time, from daily usage of contact lens, the proteins can end up in your bloodstream via eyelids. Your immune system identifies these proteins as foreign invaders, similar to an allergen.
    Your body then begins creating antibodies and once these antibodies are enough in your bloodstream, the contact lenses become uncomfortable. This leads to an allergic sensation through a condition called giant papillary conjunctivitis or GPC.
    Sometimes contact lens user may find discomfort with CLs due to improper fitting of CL, uncorrected astigmatism, CL induced dry eyes, excessive digital screen usage and other allergies. Discomfort with contact lens can be identified by irritation, redness, bright light, pain in the eyes every time while lenses are worn.
    Sometimes contact lens solution could be the next cause of eye allergy because these solutions contains preservatives. Even proper cleaning of contact lenses may still leave traces of preservative. Thimersol is one of the main preservative in contact lens solutions - better to use Thimersol-free or presarvative-free contact lens solution.
    If still you have any kind of discomfort in your eyes, firstly to stop using contact lens. Prolong CL wear will increase discomfort, aggravate pain and eye infection.
    Better to consult with eye doctor for your eye discomfort, pain and infection.

Pterygium - Prevention, cause, symptoms and treatment


Pterygium

Pterygium is fleshy conjunctival membrane growth (has blood vessels) that cover the white area of the eye and slowly spread over the cornea. This growth is a kind of triangular shape. It may occur in one eye or both eyes. If it develops in both eyes called bilateral pterygium. Early-stage of pterygium is looked like pingecula, so sometimes it is difficult to differentiate between pterygium and pingecula.

Pterygium is a non-cancerous growth; sometimes this may disconfigure the eye cosmetically. Due to moderate to advanced pterygium growth person may experience redness, irritation, discomfort, and blurry vision. Pterygium grows very slowly but in very few cases it may grow rapidly.
Reason for occurrence - cause for pterygium occurrence is unclear. It could be due to overexposure to Ultraviolet rays, excessive exposure to dust and pollution. In case of dry eyes pterygium may increase. In case of injury or burn near black eyeball or its adnexa will also cause pterygium occurrence.

Stages of Pterygium

Stage 0: In this stage very small elevation appears near the black eyeball over the sclera. In this stage there is no vascularisation and conjunctival and corneal ectasia are seen.
Stage 1: In this stage small bump like mass touches the limbus.
Stage 2: In this stage bump flatten a little just on the limbus with minimal vascularisation.
Stage 3: In this stage the fleshy layer covers the area between the limbus and pupillary margin with minimal congestion and vascularisation. This stage is associated with mild to moderate astigmatism.
Stage 4: In this stage the fleshy layer reaches to central to the pupillary margin with severe congestion and dilation. This stage is associated with an increase in astigmatism and rarely leads to the limitation of eye movement.

Signs and Symptoms

Pterygium causes redness, itching, irritation, foreign body sensation, sometimes dryness in the eyes. Redness may increase when someone is exposed to air, dust, and pollution or drives without protective glass. Contact lens users may find discomfort due to poor fitting of contact lens in moderate to advanced pterygium conditions. The cosmetic appearance of the eye may not look good in the case of pterygium. Pterygium is stretching the front surface of the eye (cornea), which leads to astigmatism and higher-order aberrations which affects the quality of vision.

Treatment and prevention

  • Avoid eye rubbing excessively.
  • To wear protective glasses (covering full eyes).
  • UV light protected glasses.
  • Lubricants (eye moisten drops).
  • Surgically (in case of moderation or advanced pterygium) - But recurrence rate is 2-5% after pterygium surgery. 
There are different techniques to remove pterygium surgically:
a. Pterygium excision with autologous conjunctival autografting
b. Pterygium excision with mitomycin C,
c. Pterygium excision with conjunctival limbal autograft
d. Pterygium excision with amniotic membrane transplantation

During the pterygium surgery fleshy mass is removed and replaced with a graft of associated membrane tissue to prevent recurrent pterygium growths. And this graft is attached either with sutures or fibrin glue, post pterygium surgery eye experienced lesser discomfort, and recovery time reduces with fibrin glue. But fibrin glue is having its own risk of transmitting infection (viral) and more inflammation.

Recovery time

Post pterygium surgery redness, irritation, foreign body sensation, and graft dissolving usually takes 6-8 weeks but this healing time may change due to the type of technique used during surgery.

Contact Lens and Eye Allergies - Reasons

Contact Lens and Eye Allergies

 The option to correct a refractive error (vision correction) is spectacle, contact lens, or refractive surgeries. Each of those choices has its advantages and disadvantages downside. 

Spectacles are the foremost commonly used for refractive correction. All three types of corrective choices for refractive error are simply offered in developing and developed countries. Though, the selection varies from the individual affordability, place, and nature of work, profession, socioeconomic status, and hobbies. 


Of those corrective options, contact lens has been playing an important role in providing vision to the countless users worldwide with several advantages like comfort, convenience, quality vision, wider the field of view, and different optical advantages over spectacles. Apart from the natural look it also opens the door for an unlimited selection of sunglasses.


Contact lens penetration in India was reported as ~5.5% of the target population 18 million. This can be considered low compared to other Asian countries like China (17%), Korea (16%), Malaysia (25%), and Singapore (35%). 


The contact lens provides safe and effective vision correction if proper lens care is taken care of as recommended by the practitioner. However, contact lens wearer may have a risk of an eye infection if they fail to wear, clean and disinfect, their contact lens as per instructions directed.


The phrase ‘allergic reaction’ could be causing up images of hives or the sudden sensation of restricted airways, but did you recognize that an allergy can develop slowly? After all, you will gradually become allergic to belongings you use every day, like your soap, favorite beverage, or maybe your contact lenses.


If you develop an allergy with contact lenses, you’ll first notice some itching and irritation. If the condition is not taken care of promptly then feeling of heaviness within the eyelids, redness, swelling, and discharge may develop.


As your eye responds to the contact lens, inflammation causes small bumps formation under the eyelids called papillae. The bumps are visible when a doctor inverts the eyelid to have a glance. When these bumps continue to enlarge - and that they can get as big as a millimeter each called giant papillary conjunctivitis - the condition worsens and your eyes become very sensitive to bright light and contact lenses. 


So don’t get frustrated – It is possible that you are allergic to your contact lens material (if hygiene and disinfection is proper) or maybe you are allergic to any ingredient of contact lens solution.
