AddOn® SML (Scharioth macula lens)
The AddOn SML was developed by Dr. Dr. Gábor B. Scharioth (Recklinghausen, Germany) for patients with advanced, dry macular degeneration and features a specially designed central optics with +10 D that acts as a miniaturized magnifying glass in the eye. The AddOn SML thus combines proven AddOn technology with a central magnification, without influencing distance visual acuity or the field of vision. The IOL can give patients with advanced dry AMD an opportunity to optimize their near vision and restore their reading capabilities.
1st INJECT Instrument
Single-use manual injector for the implantation of an AddOn IOL into the sulcus.
From 1.8 to 2.4 mm, depending on the cartridge size. Recommended for AddOn: 2.0 to 2.4 mm.
Cartridge + injector in blister; 1 disposable injection kit per box.
Silicone plunger for push injections.
3 years after sterilization.
Special click-lock system and guide rails for the easy placement of the lens.

What the designer is saying
“During my career in ophthalmology, macular diseases have always been a particular concern of mine, especially age-related macular degeneration. With time, it became clear to me that patients often perceive the treatment results of AMD completely differently to us ophthalmologists. Although an AMD patient retains their ability to focus and orient themselves generally, they are often no longer able to read. This observation, coupled with a desire to give a bit of independence and quality of life back to affected individuals, eventually lead to the development of the macula lens – the magnifying glass in the eye.”
Dr. Dr. Gábor B. Scharioth,
ophthalmologist and designer of the SML optics
The upgrade for
pseudophakic eyes
The patented sulcus lens for optimized refraction results or subsequent upgrades for increased spectacle independence.
Questions about the 1stQ AddOn® SML
- can be implanted following a standardized procedure
- works irrespective of the pseudophakic eye’s lens status
- has no impact on distance visual acuity or the field of vision
- is non-traumatically reversible in case of incompatibility
- contributes to the destigmatization of AMD patients
The AddOn SML is recommended for the treatment of dry AMD from a visual acuity of 0.1 to 0.3 as well as myopic macular degeneration, diabetic macular degeneration and other maculopathies.
Contraindications include wet AMD, severe zonulopathy, aphakia, subluxation, progressive glaucoma, iris neovascularization and generally poor retinal function. For further details, see eIFU.
No, the central optics with +10 D and a diameter of 1.5 mm is designed so that it has no impact on distance visual acuity or the field of vision.
No, the AddOn SML is only designed for the correction of pseudophakic eyes.
The Implantation the AddOn SML is recommended for dry AMD from a visual acuity of 0.1.
No, the AddOn SML is exclusively intended for treating dry AMD.
No, the AddOn SML is implanted monocularly in the better-seeing eye.
