Plain English Summary

Background and study aims
Age-related macular degeneration (ARMD) is an eye condition that causes loss of central vision, usually in both eyes. There are two main types: dry ARMD and wet ARMD. Dry ARMD develops when the part of the eye responsible for central vision (the macula) is damaged by a build-up of deposits and is unable to function as effectively. There has been a recent renewal in interest in treating ARMD with lens implantation, where the lens of the eye is removed and replaced with an artificial lens designed to improve central vision. In recent years Soleko has developed the IOL VIP intraocular lens that in combination with a rehabilitation program has improved vision in ARMD patients. See Again Europe has designed an intraocular lens to improve the vision of ARMD patients who have remaining healthy macula. From a clinical perspective the procedure to implant the See Again Lens is equivalent to that of the IOL VIP device but with the potential advantage of focusing the image on the healthier area of the macula. The aim of this study is to evaluate the performance of the See Again Lens device to improve vision in patients with dry ARMD.

Who can participate?
Patients with significant stable dry ARMD

What does the study involve?
The eye’s natural lens is replaced with a two-lens system that magnifies and diverts the image to a healthy part of the macula. The implantation procedure is performed under local anaesthetic and is expected to take 45 minutes. Eye tests are carried out within 24 hours of the implantation procedure and 2, 4, 8 and 12 weeks and 3 months later.

What are the possible benefits and risks of participating?
It is anticipated that patients’ vision will improve and achieve a two-line improvement as judged by standard eye test charts. The procedure is similar to a cataract operation and has the same risks as this routinely performed implantation.

Where is the study run from?
The study will be conducted locally as convenient for the patient. It will be performed in clinical facilities approved for eye surgery by the Care Quality Commission.

When is the study starting and how long is it expected to run for?
January 2013 to January 2017

Age-related macular degeneration


Patient suitability:
An ocular examination to determine patients’ suitability for the See Again assessment, usually 30 minutes duration.
Confirmation from patient’s GP that there is no reason why the patient should not be part of the trial.

Patient assessment:
An ocular assessment using the See Again lens set that predicts the visual acuity improvement of the implant procedure, usually 15 minutes duration.

Independent assessment:
An independent ocular assessment of the patient before the implant procedure is performed, usually 1 hour duration.

Pre operation assessment:
An ocular examination performed immediately prior to performing the implant procedure, expected to take 15 minutes.

Implant the lens system:
Perform the implant procedure of the See Again lens system under local anesthetic, expected to take 45 minutes.

Post operation assessment:
Initial ocular examination within 24 hrs of the implant procedure being performed, expected to take 15 minutes.

2 weeks post operation assessment:
Ocular examination 2 weeks post performing the implant procedure, expected to take 30 minutes.

4 weeks post operation assessment:
Ocular examination 4 weeks post performing the implant procedure, expected to take 30 minutes.

8 weeks post operation assessment:
Ocular examination 8 weeks post performing the implant procedure, expected to take 30 minutes.

12 weeks post operation assessment:
Ocular examination 12 weeks post performing the implant to determine that vision has stabilised, expected to take 30 minutes.

Independent post operation assessment:
Independent visual acuity test to be performed after 3 months, usually 1 hour duration.

Primary outcome measures

1. An improvement from baseline in the patients final best corrected visual acuity (using ETDRS Chart). An improvement of 2 lines or more will constitute a positive result for a patient.
2. Mean or median improvement values will also be analysed at 3 months.

The measures of the independent assessor will be employed.

Secondary outcome measures

The proof of concept secondary outcome measures are
1. Endothelial cell count will be compared to the patient’s baseline. A deterioration of less than 20% will constitute a positive result.
2. Improved mobility of the patient, this will be subjective based on patient response. Any perceived improvement in mobility will constitute a positive result.
3. Improved wellbeing of the patient, this will be subjective based on patient response to navigational capability and dependence on relatives and/or carers. Any perceived improvement in wellbeing will constitute a positive result.

If successful, much larger trials will be undertaken in Ireland, UK and France that will define the predictability and reproducibility of performing the implant procedure.The health economics case will be collected from the same group of patients over a longer period (2 years) and will be based based on changes to direct healthcare costs, indirect healthcare costs and care costs in the community.
