• Understand the importance of good eye care

• Recognize the benefits of timely referrals• Be aware of indications for corneal

transplant and innovative remedies.

Objectives

•How do your actions in the hospital affect the gift of sight?

Question to Run on

The BasicsThe 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 KeratoplastyThe 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.

•Making the Referral•Approach for Donation•Maintain the Opportunity•Ventilated or Comatose Patients

Key Elements in Caring for Potential Donors

•Report all imminent/cardiac deaths within ONE HOUR

•Regardless of medical condition, age, advanced directive

•HIPAA compliant

Making the Referral

•Allows time to serve the family•Preserves organ and tissue viability•Ensures compliance with federal and state laws

Why?

• 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

Approaching for 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.

Maintain Opportunity for Corneal Donation

Poor Eye Care Can Damage the Cornea

Healthy Donor Tissue Cures Blindness
