Basic Principle & Simulation

Figure 1: Patient’s eye with a constricted pupil (near vision)

Near vision:

The pupil is constricted (near vision miosis) and light rays pass through the central region of the SML, providing a magnified image on the macula (Figure 1).
Due to the high dioptric power of the central region, sharp vision is achieved at a distance of about 15 cm.
Figure 2: Patient’s eye with a dilated pupil (distance vision)

Distance vision:

The pupil is dilated when focusing on a distant object and thus light rays passing through the peripheral region of the SML will dominate over those passing through the central region (dashed lines).

Where do I Start?

To be succesfull with the SML there are some preconditions to guarantee an adequate setup:

- You have experience with macular degeneration and low vision patients
- You are prepared for diagnosing low vision patients (available personnel and equipment)
- You have a trained doctor or optician to take care of low vision patients
- You are a cataract and refractive surgeon
- You are a retinal specialist or you have a retinal specialist in your team
- You have OCT (for macular imaging) at the clinic
- You have a doctor and/or an optician who will be dedicated for pre- and post-operative care and training of implanted patients or you cooperate or have an agreement with an organization taking care of low-vision patients.
    ​
What does it take to get happy patients?

- Precise patient selection and indication (supported by the Medicontur Scientific Team and tools)
- Alignment of expectations and reality
- Postsurgical patient training
