Module 4

Receiving Your Euclid Emerald Lenses (1/6)

Your Euclid Emerald lenses will arrive in clearly marked packaging that details the individual parameters of the lenses. Each Euclid Emerald lens is laser marked with a unique laser ID to enable easy identification of your lens. We will review the package labeling next.

Packaging Labeling(2/6)

1. Lens material and color
2. Material lot number
3. The patient’s K readings and target RX
4. Each lens parameter – BC, RC, AC1, AC2, PC, BVP, and CT – is noted next to its chord diameter
5. Each lens has a unique lens identifier laser marked on the surface
6. Manufacturing date
7. Expiration date
8. Device identifier: UDI barcode
9. Quantity of lenses contained in the package
10. Lenses may be shipped in solution; the solution lot # is recorded on your labeling

Initial Dispense (3/6) 

Be sure to clean and condition the lenses prior to use with a solution approved for use with GP lenses. Upon initial dispense, perform a fluorescein slit lamp evaluation and look for the following signs of a well-fitting lens:

• General lens centration
• Lens movement with the blink
• Formation of an early “bulls-eye” pattern

Do not dispense the lenses if you see excessive lens movement or no lens movement at all, or if the patient reports pain with the lenses. Instruct the patient on proper lens insertion and removal, care and cleaning with solution, and the instillation of lubricating drops/artificial tears.

Schedule an initial follow-up for the following morning, as early as possible.

First Follow-up Appointment (4/6)

If the patient is wearing the lenses:

• Perform a slit lamp evaluation for lens movement
• Check unaided visual acuity
• Perform a BCVA evaluation
• Check over-refraction

With the lenses off perform:

• A BCVA evaluation
• Sphero-cylinder refraction
• Corneal Topography
• A corneal health check

After the first night of wear, it’s likely the patient will not experience full correction and centration may not yet be ideal. Check back in at the one-week mark to ensure that treatment is progressing.

Recommended Follow-up Schedule (5/6)

We recommend that practitioners follow-up with their patients wearing Euclid Emerald lenses at regular intervals to ensure that the treatment is progressing as expected. Most patients experience full correction between 14-30 days after starting treatment. As the patient continues to wear the lenses, evening exams can be helpful to assess if there are issues with daytime regression.

Sample follow-up schedule:

• One-week morning visit
• One-month evening visit
• Six-month evening visit
• One-year visit

Summary (6/6)
