Palliative Efficacy of Intrastromal Amniotic Membrane Procedure in Symptomatic Bullous Keratopathy Patients.

Intrastromal amniotic membrane surgery may be an alternative to keratoplasty for pain palliation in patients with limited visual prognosis after corneal transplantation when donor tissue is scarce. With this method, hAM remains on the ocular surface longer, and superficial stromal excision is believed to provide a more regular ocular surface and extend the asymptomatic period.
