The Scharioth Macula Lens (SML) is a piggyback magnifying intraocular lens (IOL). It is designed for patients with dry, or previously stabilised wet age-related macular degeneration (AMD), as an effective intraocular visual aid.
The central optic zone of 1.5mm in diameter provides a +10.0D addition, resulting in a calculated magnification of the image of about 2.2x. A visually disabled patient may be able to see small print text or fine details. The peripheral zone of the lens is typically provided in a plano power, leaving the patient’s distance vision and visual field unaffected.
A pre-operative workup should include assessment of the near visual acuity at 15cms with a +6.00D add over the distance script. Results with the SML are very good or excellent in patients that meet the selection criteria.
To achieve optimal outcomes, post-operative visual training is required. This involves the patient reading near print for 20 minutes twice a day during the first six to eight weeks after implantation of the SML. The SML is easy to implant through a small, 2.4mm incision and is safe. As the lens is implanted into the ciliary sulcus, this allows the opportunity to reverse this procedure by easy explantation at any time after surgery.
