Abstract Details

Purpose:

To report the twelve months visual outcomes following implantation of the Scharioth add- on injectable macular lens (SML) in previously pseudophakic eyes with age related macular degeneration (AMD).

Setting:

Prospective European mutlicenter clinical trial. Study centers included Ayr, Scotland, Recklinghause, Germany, Keil, Germany, Sofia, Bulgaria, Hradec Kralove, Czech Republic.

Methods:

25 pseudophakic patients with dry or inactive wet AMD were recruited. The inclusion criteria were: age over 55, corrected distance visual acuity (CDVA) of 0.1 to 0.4 (decimal), improvement of at least three lines of corrected near visual acuity (CNVA) when tested with a +6.0 D reading addition at 15 cms, compared to a +2.5 D reading addition at 40 cms with a self illuminated ETDRS near vision chart. One eye of each patient was implanted with the SML. Patients were examined at 1 day, 1 week, 1 and 3, 6 months and 1 year post operatively.

Results:

There were no intraoperative or postoperative complications. The mean CDVA remained unchanged 0.18 decimal preoperatively compared to at 3, 6 months and 1 year postoperative visit. The CNVA at 15 cms improved from 0.25 decimal preoperatively to 0.55 at 3 months and to 0.68 at 6 months and at 1 year time gate.

Conclusions:

The injectable add- on SML appears to be safe and effective in the short to medium term in improving the CNVA in patients with AMD. Data suggests that the CDVA remains unaffected following the implantation of SML. Testing of CNVA at 15 cms with a +6.0 D near addition seems to be effective screening tool in patient selection. Further data is needed to assess the long-term safety and efficacy of this implant.
