H18.21
Corneal edema secondary to contact lens
Clinical Classification Guidelines
Excludes Type 2
- other corneal disorders due to contact lens (H18.82-)
Medical Intelligence & Overview
Corneal edema refers to swelling of the cornea, the clear front part of the eye. When caused by contact lens use, it can result from improper lens care or prolonged wear. This condition can affect vision and eye comfort if not managed properly. Recognizing the causes, symptoms, and treatment options can help individuals maintain healthy eyes while using contact lenses.
Causes & Symptoms
Clinical Causes: Extended or overnight contact lens wear Poor lens hygiene leading to bacterial, fungal, or parasitic infections Deposition of deposits or proteins on the lens surface Improper lens fitting causing mechanical trauma Pre-existing corneal conditions worsened by lens use Inadequate lens cleaning or replacement schedule
Key Symptoms: Blurred vision Eye redness and inflammation Sensation of fullness or pressure in the eye Pain or discomfort in the affected eye Sensitivity to light (photophobia) Feeling of a foreign body or irritation under the lens Watery or teary eyes
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a comprehensive eye examination by an eye care professional. This includes assessing visual acuity, examining the cornea with slit-lamp microscopy, and evaluating the extent of swelling or any signs of infection. Additional tests may include corneal thickness measurement and bacterial or fungal cultures if needed to identify underlying infections.
Treatment Protocols: Discontinuing contact lens wear temporarily Using medicated eye drops to reduce inflammation and edema Administering antibiotics or antifungal medications if an infection is present Improving lens hygiene and care routines Switching to glasses until the cornea heals Addressing underlying fitting issues or replacing lenses with appropriate options
