Corneal Disorder Due to Contact Lens

Wearing contact lenses is a popular alternative to eyeglasses for correcting vision. However, it is not without risks. One of the most common problems associated with wearing contact lenses is corneal disorders. These conditions can range from mild irritation to severe infections that can lead to permanent vision loss.

  1. Corneal Abrasions: This is the most common corneal disorder associated with contact lens wear. Abrasions occur when the surface of the cornea is scratched, usually by a foreign object or a poorly fitting contact lens. Symptoms of a corneal abrasion include pain, redness, and sensitivity to light. If left untreated, an abrasion can lead to a corneal infection.
  2. Corneal Ulcers: This is a serious infection of the cornea that can lead to permanent vision loss. Contact lens wearers are at higher risk of developing corneal ulcers, especially if they do not follow proper hygiene and care practices. Symptoms of a corneal ulcer include pain, redness, discharge, and blurred vision.
  3. Corneal Neovascularization: This is a condition where new blood vessels grow into the cornea. It can occur as a result of wearing contact lenses that do not allow enough oxygen to reach the cornea. Symptoms of corneal neovascularization include redness, blurred vision, and sensitivity to light.
  4. Giant Papillary Conjunctivitis: This is an allergic reaction to contact lens wear. It occurs when the inner surface of the eyelid becomes inflamed, causing papillae (small bumps) to form. Symptoms of giant papillary conjunctivitis include itching, redness, and a feeling of something in the eye.

Preventing corneal disorders due to contact lens wear is possible by following proper hygiene and care practices. These include:

  • Washing hands before handling contact lenses
  • Cleaning and disinfecting contact lenses as per the instructions of the manufacturer
  • Avoiding sleeping in contact lenses
  • Replacing contact lenses as per the recommended schedule
  • Using lubricating eye drops if the eyes feel dry or uncomfortable

It is important to seek medical attention if any symptoms of corneal disorder occur. Early treatment can prevent permanent vision loss and other complications.

Overall, while contact lenses can offer a convenient and effective way to correct vision, it is important to be aware of the risks associated with their use. By following proper hygiene and care practices, contact lens wear
