Contact lenses are a popular vision correction option, but their improper use or maintenance can lead to various complications that affect the eyes. It's essential to follow proper hygiene and care guidelines to minimize the risk of complications. Some potential complications from contact lens wear include:
Corneal Infections (Keratitis): Bacterial, viral, or fungal infections of the cornea can occur due to poor hygiene, inadequate lens cleaning, or extended wear. Symptoms may include redness, pain, blurred vision, light sensitivity, and discharge. Severe infections can lead to corneal ulcers and vision loss.
Corneal Abrasions: Scratches or injuries to the cornea can result from contact lens-related trauma or from dust, debris, or rough handling of lenses. Symptoms include pain, foreign body sensation, tearing, and light sensitivity.
Contact Lens-Related Dry Eye: Prolonged lens wear can lead to reduced tear production and dryness, causing discomfort, redness, blurred vision, and irritation.
Giant Papillary Conjunctivitis (GPC): GPC is an allergic reaction characterized by inflammation of the conjunctiva, typically caused by protein buildup on the lenses or lens-related irritation. Symptoms include itching, redness, mucus discharge, and discomfort.
Corneal Neovascularization: Long-term lens wear that restricts oxygen flow to the cornea can stimulate new blood vessel growth, increasing the risk of complications.
Corneal Edema: Extended wear of contact lenses, especially overnight, can lead to fluid accumulation in the cornea, causing swelling, blurred vision, and discomfort.
Allergic Reactions: Allergic responses to lens materials, cleaning solutions, or other components can lead to itching, redness, tearing, and discomfort.
Lens Discomfort or Poor Fit: Wearing improperly fitting lenses can cause discomfort, redness, and blurred vision.
Lens Deposits: Protein, lipid, and calcium deposits can accumulate on contact lenses, affecting vision and causing discomfort.
Hypoxia-Related Complications: Insufficient oxygen supply to the cornea due to tight-fitting or extended-wear lenses can increase the risk of complications such as corneal ulcers, neovascularization, and inflammation.
Peripheral Ulcerative Keratitis (PUK): Inflammatory eye conditions that can be associated with autoimmune diseases and systemic conditions may occur in contact lens wearers.
To minimize the risk of complications, follow these guidelines for safe contact lens wear:
Follow proper hygiene: Wash hands thoroughly before handling lenses, and avoid using tap water or saliva to clean lenses.
Clean and disinfect: Use recommended lens cleaning solutions and follow proper cleaning and disinfection protocols.
Replace as directed: Replace lenses as prescribed by your eye care professional.
Avoid extended wear: Remove lenses before sleeping unless specifically designed for extended wear.
Avoid water exposure: Remove lenses before swimming or using hot tubs.
Regular eye exams: Schedule regular checkups with an eye care professional to monitor eye health and lens fit.
Follow instructions: Adhere to your eye care professional's recommendations for lens type, replacement schedule, and care.
If you experience discomfort, redness, vision changes, or any unusual symptoms while wearing contact lenses, remove them immediately and seek advice from an eye care professional. Prompt attention can help prevent complications and preserve your eye health.
