Corneal opacities or scarring

• 60% — With documented incapacitating episodes requiring 7 or more treatment visits for an eye condition during the past 12 months
• 40% — With documented incapacitating episodes requiring at least 5 but less than 7 treatment visits for an eye condition during the past 12 months
• 20% — With documented incapacitating episodes requiring at least 3 but less than 5 treatment visits for an eye condition during the past 12 months
• 10% — With documented incapacitating episodes requiring at least 1 but less than 3 treatment visits for an eye condition during the past 12 months

Because VA can rate keratopathy under either visual impairment or incapacitating episodes, evidence supporting both approaches strengthens your record.

For the incapacitating-episode path, medical records showing clinic visits specifically for treatment of your eye condition are central. Each record should clearly reflect that the visit was for treatment, not a routine check. Records documenting the type of treatment received, such as injections, laser procedures, immunosuppressant prescriptions, or surgical interventions, help confirm that the visit qualifies. The number of qualifying visits in the past 12 months is what drives the rating percentage.

For the visual impairment path, ophthalmology or optometry records showing measured visual acuity, visual field testing results, and any documented loss of light sensitivity or other functional vision changes are relevant. These findings feed into the separate visual acuity and visual field formulas VA uses.

Personal statements from you or people who know you, describing how your vision or eye symptoms affect your ability to work, read, drive, or manage daily tasks, can help show the real-world impact of the condition alongside the clinical records.
