Moderator:
Sherri Lamon, RN, PIH Health
Objectives
• Understand the importance of good eye
care
• Recognize the benefits of timely referrals
• Be aware of indications for corneal
transplant and innovative remedies.
Question to Run on
• How do your actions in the hospital
affect the gift of sight?
The Basics
The goal of the cornea is to
focus light to a point on the retina.
What two requirements
are necessary for the cornea to
perform this function?
Transparency and correct shape
Corneal Anatomy
• Epithelium- 50 microns
• Bowman’s Layer- 12 microns
• Stroma- 450-900 microns
• Descemet’s membrane- 3-12 microns
• Endothelium- 4-6 microns

IntraLase Enabled Keratoplasty
The IntraLase Enabled Keratoplasty software
can be programmed to produce different
configurations with computer precision.
Historical use of trephination utilizing
different shapes has taught us that different
configurations have unique features that can
be used for specific indications.
IntraLase Enabled Keratoplasty
The IntraLase® FS ophthalmic surgical laser is
cleared for the creation of a lamellar cut/resection
of the cornea for lamellar keratoplasty and for the
creation of a PENETRATING CUT/INCISION for
penetrating keratoplasty
The IntraLase FS surgical laser can perform the following
cuts that when combined at different angles can create
various geometrically shaped corneal resections at the
surgeon’s desired depth.
IntraLase Enabled Keratoplasty
The IntraLase Enabled Keratoplasty application allows
the user to perform three cut segments: a posterior side cut,
lamellar cut, and anterior side cut.

Key Elements in
Caring for Potential Donors
• Making the Referral
• Approach for Donation
• Maintain the Opportunity
• Ventilated or Comatose Patients
Making the Referral
• Report all imminent/cardiac deaths
within ONE HOUR
• Regardless of medical condition, age,
advanced directive
• HIPAA compliant
Why?
• Allows time to serve the family
• Preserves organ and tissue viability
• Ensures compliance with federal and
state laws
Approaching for Donation
• Most deaths will not be eligible for donation
• Do not approach independently of
OneLegacy.
• Have medical chart available for OneLegacy
to determine suitability.
• LNOK contact information
Maintain Opportunity for
Corneal Donation
• Ventilated or comatose patients- lubricate
eyes frequently : every 4-6 hours gel is
better than tears
• Deceased patients- wait for go ahead
from One Legacy: eye care may interfere
with M.E./coroner's investigation.
Poor Eye Care
Can Damage the Cornea
Healthy Donor Tissue
Cures Blindness
