2

Lubricating Eye Drops

Preservative-free artificial tears provide ocular surface comfort and help protect corneal epithelium from recurrent erosions characteristic of lattice dystrophy.

medication
3

Protective Eyewear

Appropriate protective glasses during activities with eye injury risk to prevent corneal trauma that can precipitate acute erosive episodes.

lifestyle

Additional treatment options

Phototherapeutic Keratectomy (PTK)

Excimer laser ablation of superficial corneal opacities removes amyloid deposits and smooths epithelial irregularities to improve vision.

procedure

Anterior Lamellar Keratoplasty

Selective transplantation of anterior corneal layers preserving healthy endothelium, reducing rejection risk compared to full-thickness transplant.

surgical

Recurrence Surveillance

Regular corneal mapping and biomicroscopic examination to detect deposit recurrence and guide timing of repeat interventions.
