Vision and Balance Changes After Bilateral Implantation of Toric IOLs

Intraocular lenses are medical devices that are implanted in patients during cataract surgery. At Plymouth University NHS trust the standard lens is a monofocal non-Toric lens unless the patient has astigmatism greater than 4.00D. This study involves implantation of a toric lens in the intervention group where astigmatism is greater than 1.00D. The lens is called the toric IOLS- Zeiss AT TORBI, will be implanted bilaterally instead of standard monofocal IOLs- Zeiss CT ASPHINA, used in routine cataract surgery within NHS.
