Lamellar Channel Deposit

Lamellar channel deposits 

  • Refractive surgical procedure which produce a predictable alteration of the recipient corneal curvature by inserting two segments of an intrastromal refractive device into cornea stromal channels.
  • Indication: eyes with refractive errors from -1 to -4.50 D.

Side effects:

  • Peripheral corneal haze, which is usually not visually significant
  • Lamellar channel deposits of collagen and proteoglycan due to the wound healing process
  • Microperforation or tear of Descemet's membrane may occur during dissection of the stromal channel
  • Irregular astigmatism has also been reported
  • Other rare complications such as persistent focal corneal edema and poor visual acuity have prompted explantation of the device
