Implantation of Scharioth macula lens in patients with age-related macular degeneration: results of a prospective European multicentre clinical trial
Abstrakt
Objective: To report the visual and refractive outcomes following monocular implantation of a supplementary (piggyback) Scharioth macula lens (SML) in previously pseudophakic eyes with age-related macular degeneration (AMD). Methods and analysis: Prospective European multicentre clinical trial. 50 eyes of 50 pseudophakic patients with either dry or previously treated and stable neovascular AMD for at least 6 months were included.
The inclusion criteria were age over 55, corrected distance visual acuity (CDVA) of 0.4-0.1 (decimal), improvement of at least three lines of corrected near visual acuity (CNVA) when tested with a +6.0 dioptre (D) reading addition at 15 cm, compared with a +2.5 D reading addition at 40 cm using a standardised, self-illuminated Early Treatment Diabetic Retinopathy Study near vision chart. The SML intraocular lens (IOL) was implanted as an add-on/piggyback IOL in the ciliary sulcus, monocularly in the better seeing eye of each subject meeting the inclusion criteria.
Results: There were no intraoperative complications. One subject had the SML explanted in the postoperative period due to postoperative glare/halos.
The mean CNVA improved from 0.23+-0.12 (decimal) preoperatively to 0.57+-0.33 at 1 year. The mean CDVA remained unchanged measuring 0.19+-0.13 preoperatively and 0.19+-0.09 at 1 year postoperatively.
Conclusion: The SML appears to be safe and effective in improving the CNVA in patients with AMD. Data suggest that the CDVA remains unaffected following implantation.
Further data are needed to assess the long-term safety and efficacy.
