What is a Bandage Contact Lens?

A bandage contact lens is a soft, high-water-content silicone-hydrogel lens worn continuously for days or weeks to protect a damaged or healing cornea. Unlike a refractive contact lens, its purpose is therapeutic rather than optical: it covers the surface, prevents the eyelid from scraping over a healing area, and allows the corneal epithelium to grow back smoothly.

Lens shields the defect from the lid; the epithelium grows back underneath the lens.

Figure 1. A bandage contact lens is a soft, high-oxygen-permeable lens that vaults over the corneal surface. With every blink the upper eyelid would otherwise scrape across an open epithelial defect, breaking it down again. The lens separates the lid from the healing surface and allows the epithelium to regenerate smoothly underneath.

When a Bandage Contact Lens is Used

  • After corneal cross-linking — worn for the first week while the epithelium heals
  • After photorefractive keratectomy (PRK) or phototherapeutic keratectomy (PTK)
  • Recurrent corneal erosion — sometimes for several weeks to allow firm epithelial adhesion
  • Persistent epithelial defects in neurotrophic keratopathy, after severe infections or in chemical injury
  • Exposed corneal sutures after keratoplasty, while awaiting suture removal
  • Bullous keratopathy — to control symptoms from burst bullae in eyes awaiting DSAEK / DMEK

How It Is Used

The lens is fitted at the slit lamp and chosen for size, base curve and oxygen permeability. It is worn continuously, day and night, and replaced or removed at follow-up. Three rules apply during bandage lens wear:

  • Prophylactic topical antibiotic drops are used to reduce the risk of microbial keratitis
  • The lens is not removed by the patient at home unless specifically instructed
  • Any pain, redness or discharge needs same-day review — symptoms can mean infection under the lens
A bandage lens is a temporary measure, not a long-term solution. Continuous wear increases the risk of infection. Once the underlying surface problem has settled, the lens is removed and any underlying cause (e.g. lid disease, dry eye, neurotrophic surface) is addressed separately.
✔ Bandage Contact Lens Care at Suraj Eye Institute

We use bandage contact lenses routinely after cross-linking, for recurrent corneal erosions, persistent epithelial defects, neurotrophic keratopathy and exposed sutures. Lenses are fitted at the slit lamp, prophylactic antibiotic cover is started immediately and review is scheduled to remove or replace the lens at the right time.

Frequently Asked Questions

Will I be able to see with the bandage lens in?
Yes. Bandage lenses are clear and you will be able to see, often more comfortably than without the lens because the surface is smoothed. Vision may not be sharp if there is an epithelial defect or surface oedema, but most patients can read and function normally.

Why do I need antibiotic drops if my eye is not infected?
Any continuous-wear contact lens increases the risk of microbial keratitis. Prophylactic topical antibiotic drops while the bandage lens is in place reduce this risk to a very low level. The drops are stopped when the lens is removed.

How long will I need to wear it?
It depends on the indication. After cross-linking or PRK, typically 5–7 days while the epithelium heals. For recurrent erosion, several weeks. For persistent epithelial defects after infection or trauma, occasionally several months under close supervision.

Can I take the lens out and put it back in at home?
No. The bandage lens is fitted and removed at the slit lamp by your eye specialist. Removing and replacing it at home risks dislodging the healing epithelium and introducing infection.

What if it falls out?
If the lens falls out, leave it out — do not try to replace it. Continue any prescribed drops, protect the eye with sunglasses and contact the eye unit the same day so a new lens can be fitted if needed.
