EXPLANATION OF STUDY
THIS STUDY IS NOW CLOSED. THIS PAGE IS NOW FOR INFORMATION ONLY.
Optometric Technology Group is conducting a study to measure the optical quality of the eye and of the cornea in a population with keratoconus. The purpose of the study is to quantify the optical distortions (aberrations) of the eye and the cornea and to measure their effects on vision. The aim of the project is ultimately to design contact lenses and in particularly soft contact lenses that would correct the aberrations (distortions) of the cornea created by the keratoconus and give improved vision in this group of patients traditionally only suitable for rigid contact lenses fitting. The potential benefit will be of similar vision to rigid contact lenses but improved comfort.
The participants in this study will be selected on the basis of having been diagnosed or suspected as having keratoconus in one eye or both eyes. It also includes subjects who have had a corneal graft following keratoconus. The investigation will be carried out on at least 50 subjects.
If you participate in the study, you will attend for one visit of approximately 1½ hours. There is no financial compensation for participation in this study, although you may receive compensation for travel expenses. However, you may benefit indirectly through the advancement in understanding of the corneal aberrations of the human eye and their implications for management and treatment of conditions such as keratoconus. Your vision will be evaluated during the study, however new optical corrections (spectacles or contact lenses) will not be prescribed during this time.
The study will involve the testing of vision using conventional clinical instruments. The following tests will then be undertaken with spectacle correction and contact lens correction (if applicable):
The results of this study may be used for medical and scientific publications, but your identity will not be disclosed. All information, which is collected about you during the course of the research, will be kept strictly confidential. Any information about you which leaves the research clinic will have your name and address removed so that you cannot be recognised from it. It is requested that you do not disclose information concerning this investigation to anyone other than Optometric Technology Group investigators without prior permission.
This study is funded by Optometric Technology Group Limited which is an independent research facility. The plan for this study has been reviewed and approved by an independent local research Ethics Committee.
WITHDRAWAL FROM THE STUDY
It is up to you to decide whether or not to take part. If you do decide to take part you will be given this information sheet to keep and be asked the sign a consent form. If you decide to take part you are still free to withdraw at any time and without giving a reason. A decision to withdraw at any time, or a decision not to take part, will not affect the standard of care you receive.
There is no provision for on going eye care and care by your private eye practitioner should be resumed at the conclusion of the study or if you are discontinued or withdrawn from this study.
You will be given a copy of this information sheet to keep and a copy of the signed consent form.
