NCT01654159
Brief Summary:
The main objective of this research is to assess visual function and optical performance of CE marked, implanted intraocular lenses to understand the individual factors that affect their performance and how these may be improved in future designs and to evaluate measurement techniques.
All outcome measures will be captured 3-6 months after surgery
Detailed Description:
A cataract occurs when the natural lens of the eye, which plays a major role in the focusing of light and production of sharp visual images, becomes cloudy and hardens, resulting in a loss of visual function. Left untreated, cataracts can cause preventable blindness. During cataract surgery the natural lens is removed and a man-made intraocular lens (IOL) is implanted in its place.
IOL technology has advanced significantly in recent years and as a result the main goal of cataract surgery is no longer simply the successful removal of the cloudy lens and restoration of vision. Providing patients with the best possible refractive outcome and the best possible visual quality is now much more important when assessing surgery outcomes.
Aspheric, multifocal and accommodating IOLs are among the new designs developed to improve visual outcome after cataract surgery. In order to assess the effectiveness of these designs, visual function needs to be evaluated both objectively and subjectively following their implantation. Such evaluation allows the continued evolution of these IOL designs towards optimum. This proposed research study, which aims to assess the visual function and optical performance of new CE marked IOLs after implantation, could significantly contribute to the enhancement and development of improved IOL designs in the future.
We have successfully conducted similar patient trials for the past 5 years. As new IOL designs are constantly being developed, approved and CE marked, this type of research study will always have the potential to offer new information that is not currently available and has not previously been assessed or published and could contribute towards improved IOL designs in the future.
All outcome measures will be captured 3-6 months after surgery
