Are you a contact lens wearer? Have you ever experienced discomfort, redness, or decreased tolerance while wearing your lenses? If so, you may be familiar with the potential complications that can arise from wearing contact lenses. This article delves into the various corneal complications that can occur as a result of contact lens use, including epithelial edema, microcysts, abrasions, and more. Learn about the impact contact lenses can have on your cornea and how to minimize the risk of complications.
Types of Corneal Complications
One common type of corneal complication that can occur from wearing contact lenses is corneal de-epithelialization. This refers to the loss of the outermost layer of cells on the cornea. Corneal de-epithelialization can result in various symptoms, such as foreign body sensation, itching, redness, and decreased tolerance of contact lenses. It can also lead to more severe complications, including corneal scarring, corneal thinning, corneal perforation, and corneal distortion.
Corneal scarring occurs when the cornea heals after an injury or inflammation, resulting in the formation of fibrous tissue. This can affect the clarity of vision and may require additional treatment to improve visual acuity. Corneal thinning refers to the progressive thinning of the cornea, which can weaken its structural integrity and increase the risk of corneal perforation. Corneal perforation is a serious complication where there is a hole or rupture in the cornea, leading to significant visual impairment and potential infection.
Corneal distortion refers to changes in the shape or curvature of the cornea, which can result in astigmatism or irregular astigmatism. This can cause visual distortions and may require contact lens refitting or a change in lens material to improve visual clarity. It is important to diagnose and manage these corneal complications promptly to prevent further damage and preserve vision.
Symptoms of Corneal Complications
When it comes to corneal complications from wearing contact lenses, it’s important to be aware of the symptoms. These can include blurred vision, light sensitivity, redness of the eye, and swollen eyelids. If you experience any of these symptoms, it’s crucial to seek prompt medical attention to prevent further complications and ensure proper treatment.
Blurred vision
If you experience blurred vision while wearing contact lenses, it may be a symptom of corneal complications. Blurry vision can occur due to various reasons, including dry eyes, corneal ulcers, and improper contact lens hygiene. Dry eyes can cause the contact lens to stick to the cornea, leading to blurred vision. Corneal ulcers, which are open sores on the cornea, can also result in blurred vision. It is important to maintain good contact lens hygiene by cleaning and disinfecting them properly to prevent any corneal complications. In severe cases where corneal complications cannot be resolved, corneal transplantation may be necessary to restore clear vision. If you experience persistent blurred vision while wearing contact lenses, it is important to seek medical attention to prevent further damage to the cornea.
Light sensitivity
If you experience light sensitivity while wearing contact lenses, it could be a symptom of corneal complications. Light sensitivity, also known as photophobia, is a common symptom associated with corneal ulcers, corneal scarring, and other corneal complications caused by contact lens wear. When the cornea is damaged or irritated, it becomes more sensitive to light, leading to discomfort and eye irritation. This can manifest as a decreased tolerance for contact lenses and mild to severe pain in the eyes. Itching, redness, and foreign body sensation may also be present. If you are experiencing these symptoms, it is important to seek medical attention and consider temporarily discontinuing contact lens wear to prevent further complications.

Redness of the eye
One common symptom of corneal complications from wearing contact lenses is redness of the eye. Redness occurs due to irritation and inflammation of the cornea, which can be caused by various factors like corneal ulceration, contact lens hygiene issues, corneal neovascularization, and corneal irregularity. It is important to address redness promptly as it may indicate a more serious underlying issue. To prevent corneal complications and reduce the risk of redness, it is essential to practice good contact lens hygiene, such as proper cleaning and disinfection, avoiding sleeping or showering with lenses, and following the recommended wearing schedule. Regular eye exams and consultations with an eye care professional can also help detect any potential issues early on and provide appropriate treatment.
Swollen eyelids
Swollen eyelids can be a symptom of corneal complications caused by wearing contact lenses. When the cornea becomes damaged or irritated, it can lead to inflammation, which can result in swollen eyelids. This swelling is often accompanied by other symptoms such as redness, itching, and decreased tolerance of contact lenses. It is important to address these symptoms promptly to prevent further complications and minimize the impact on vision. Treatment options for corneal complications include temporarily stopping contact lens wear, using antibiotic or anti-inflammatory medications, and seeking urgent care for persistent symptoms. Prevention strategies such as proper contact lens wear and hygiene practices should also be followed to reduce the risk of corneal complications. It is essential to adhere to management guidelines and seek professional advice for long-term effects and optimal eye health.
Causes of Corneal Complications
There are several causes that can lead to corneal complications from wearing contact lenses. These causes include:
- Allergic reactions: Some individuals may experience allergic reactions to the materials used in contact lenses, such as the lens itself or the solutions used for cleaning and disinfecting. These reactions can result in inflammation and irritation of the cornea.
- Protein deposition: Over time, proteins from tears can build up on the surface of contact lenses. This protein deposition can create a breeding ground for bacteria and other microorganisms, increasing the risk of corneal infections.
- Trauma: Physical trauma to the eye, such as rubbing or scratching the cornea while inserting or removing contact lenses, can cause corneal complications. This trauma can lead to corneal abrasions, swelling, and other issues.
- Corneal infections: Bacterial, viral, or parasitic infections can occur when microorganisms find their way onto the surface of contact lenses. These infections can cause significant damage to the cornea if left untreated.
It is important to be aware of these causes and take appropriate measures to prevent corneal complications. This includes properly cleaning and disinfecting contact lenses, avoiding wearing lenses for extended periods, and seeking prompt medical attention if any symptoms of corneal complications arise.
Risk Factors for Corneal Complications
To minimize the risk of corneal complications, it is important for you to be aware of the factors that increase your chances of developing these issues while wearing contact lenses. Several risk factors can contribute to corneal complications, including contact lens overwear, sleeping in contact lenses, showering or using a hot tub in contact lenses, and ocular trauma.
Prevention strategies are crucial in reducing the likelihood of corneal ulceration and other complications. Practicing good contact lens hygiene, such as properly cleaning and disinfecting your lenses, can help prevent infections and inflammation. It is also important to follow your eye care professional’s instructions for wearing and caring for your lenses.
Corneal edema management is another important aspect of preventing complications. Adequate oxygen delivery to the cornea is essential, so it is recommended to choose contact lens materials with higher oxygen permeability. Additionally, reducing contact lens wearing time and ensuring an optimal fit can help prevent corneal edema.
Preventing corneal neovascularization, the development of new blood vessels in the cornea, is also crucial. This can be achieved by removing any inciting stimuli, such as poorly fitting lenses, and using topical corticosteroids to aid in vessel regression.
Complications and Treatment of Corneal Complications
To effectively manage corneal complications from wearing contact lenses, it is important for you to understand the various treatment options available. Here are three key treatment approaches to address different corneal complications:
- Corneal irregularity treatment: Corneal irregularities can occur due to contact lens wear. Treatment options may include temporary cessation of contact lens wear, prophylactic antibiotic therapy, refitting of contact lenses, and patient education. It is important to address corneal irregularities promptly to prevent further damage.
- Corneal edema prevention: Corneal edema can result from acute or chronic hypoxic corneal conditions and inadequate contact lens fit. Treatment options may involve selecting a lens material with higher oxygen permeability, reducing contact lens wearing time, and ensuring an optimal contact lens fit. Early intervention and proper management can help prevent corneal edema.
- Corneal distortion management: Contact lens wear can lead to corneal curvature alterations and corneal distortion. Treatment may involve contact lens refitting and changing lens material. It is crucial to rule out irregular astigmatism and address corneal distortion to maintain good visual acuity.
Understanding the mechanisms of corneal sensitivity, such as corneal hypoesthesia, can also aid in managing corneal complications. Inflammatory complications, such as sterile infiltrates and neovascularization, may require prophylactic antibiotic coverage, topical steroid drops, and removal of inciting stimuli. Timely treatment and close follow-up care are essential for effective management of corneal complications. Remember to seek urgent care for persistent symptoms and practice appropriate contact lens wear to prevent complications.
Corneal Sensitivity
Corneal sensitivity is reduced by contact lenses, affecting the ability to perceive touch on the cornea. This decrease in corneal sensitivity is known as corneal hypoesthesia. Contact lenses interfere with the tear film interaction on the cornea, which plays a vital role in maintaining the cornea’s integrity. The tear film acts as an adhesive force between the lens and the cornea, improving the function of the contact lens. It also fills in any corneal irregularities and shapes the front surface of the tear lens. However, contact lenses can hinder this interaction, leading to a reduction in corneal sensitivity.
Corneal hypoesthesia can have implications for contact lens wearers. It can make it difficult to detect and respond to any corneal irregularities or abnormalities, increasing the risk of corneal complications such as corneal abrasions or infections. Additionally, reduced corneal sensitivity can contribute to corneal neovascularization, where new blood vessels develop in response to corneal hypoxia and inflammation caused by contact lens wear.
It is important for contact lens wearers to be aware of the potential decrease in corneal sensitivity and to regularly monitor their eye health. If any symptoms of corneal irregularity or discomfort arise, it is crucial to seek prompt medical attention. Proper contact lens hygiene and adherence to recommended wearing schedules can help minimize the risk of corneal complications associated with reduced corneal sensitivity.
