Eight Steps to the Correct Loading of the Rayner C-flex® family of IOLs in the Rayner Single Use Soft-Tipped IOL Injector

(R-INJ-04)

Step 1
Aseptically transfer the injector to the sterile field by tipping it from the tray. Fully retract the plunger ensuring that the blue tip does not protrude into the loading bay.

Step 2
Open the loading bay flap fully to 90° and sparingly apply a suitable commercially available viscoelastic inside the nozzle and to both grooves of the loading bay. Balanced salt solution alone should not be used as a lubricant.

Step 3
Carefully peel back the foil lid of the lens blister. Gently lift out the lens using parallel tipped, non-serrated forceps e.g. Kelman-McPherson. Rinse the IOL with sterile Balanced Salt Solution.

Step 4
Position the lens centrally in the loading bay in a “reverse – S” configuration.
Ensure that the nearest edge of the optic is securely under the edge (lip) of the bay as shown.

Step 5
Hold open the flap and press down on lens with closed forceps to ensure that the furthest edge of the optic is securely under the edge (lip) of the flap as shown (A). Ensure the haptics are completely within the loading bay (B, C, D and E).

Step 6
While keeping the lens in position with open forceps, gently close the flaps of the injector ensuring that no parts of the optic or haptics are trapped before locking the flaps firmly together.

Step 7
Visually observe that the lens is symmetrically folded within the loading bay. Advance the plunger in a slow controlled manner. Anticipate an initial slight but not excessive resistance, which could indicate a trapped lens.

Step 8
Observe that the lens remains symmetrically folded within the nozzle.
Once the lens exits the nozzle, stop depressing the plunger.
The plunger is only to be depressed once. The injector is for single use only.

Tips to remember for achieving a successful implantation

1. This is a single use device, never attempt to reuse it.
2. Do not depress the plunger prior to loading the lens.
3. Always add viscoelastic to the loading bay and close fully before injection.
4. Ensure that prior to loading, the injector plunger is fully retracted.
5. Ensure that NO part of the lens is projecting outside the edges of the loading bay before closing flaps.
6. When closing and locking the injector flaps, any resistance could indicate a trapped lens.
7. When depressing plunger too much resistance could indicate a trapped lens.
8. Before injecting, always ensure correct IOL configuration within the nozzle
and that the injector is correctly orientated (as in Step 8, i.e. with closed flaps facing upwards).
9. Once lens is expressed do not retract plunger.
