First Removal of Retained Descemet Membrane Using Femtosecond Laser
Purpose
To report use of femtosecond (FS) laser for removal of retained Descemet's membrane (DM) post pnentrating keratoplasty.
Methods
A case report of a 22 year old male who had penetrating keratoplasty for keratoconus.
Postoperatively , a retained retrocorneal membrane with double anterior chamber was
noticed.The membrane was removed with the FS laser. After the FS assisted descemetorhexis, the free floating membrane was removed through a 2mm wide limbal incision with forceps.
Results
Histopathological evaluation confirmed the diagnosis of retained DM. There was improvement of preoperative uncorrected visual acuity from 20/300 to 20/50.
Endothelial cell count of the central cornea was 810 preoperatively and 778 postoperatively.
Conclusion
Inadvertent retention of DM may be safely treated with the FS laser. Clarity and viability of
the existing graft can be maintained .
