Research summary
Usually following cataract surgery patients would expect to have normal distance vision and not require the use of distance glasses. However, in clinical practice desired vision post cataract surgery is not achieved sometimes. In such cases a piggyback lens is used to enhance the visual outcome. This lens is placed in the ciliary sulcus (space between the iris and the lens). Often this piggyback lens is not the best fit for the ciliary sulcus space and it moves. This study will be using ultrasound biomicroscopy to measure the cilary sulcus dimensions pre and postoperatively to estimate the normal anatomy and it's variations. Patients in this study will be randomised as to which way the intraocular lens is placed in the eye (horizontally or vertically) at the time of their cataract surgery. Patients requiring cataract surgery in both eyes will be identified from the Eye Hospital at the Royal Sussex County Hospital. Patients will be in the study for up to 6 months from being identified as suitable through to the operation in the 2nd eye and a final study visit.
