Treatment of Macular Corneal Dystrophy

Medical Care for Macular Corneal Dystrophy

Recurrent corneal erosions are treated with a bandage contact lens and antibiotics. After early healing of the corneal erosion preventive treatment consists of sodium chloride 5% drops (brand name Muro 128) and artificial tear lubricating drops (e.g. TheraTears or Soothe XP) during the day and sodium chloride 5% ointment (eg, Muro 128) at bedtime.  The hypertonic salt medicine helps to secure the bond between the outer layer cells of the cornea (epithelium) and the underlying basement membrane layers to hopefully prevent recurrence of the recurrent corneal erosion.

Artificial tears should be used at least four times per day and sunglasses should be used to minimize the photophobia (light sensitivity).

Surgical Care for Macular Corneal Dystrophy

Substantial corneal erosions and a slight reduction in visual acuity can be treated with Phototherapeutic keratectomy (PTK) using an excimer laser.  PTK usually only works well for very superficial opacities. 

A severe reduction in visual acuity or large and deep opacities usually necessitate a corneal transplant.  Even after a corneal transplant the corneal deposits can come back after time.
