Research summary
The most common cause of changes in spectacle prescription in older people is cataract with different kinds of cataract causing different types of spectacle prescription change. Participants will be recruited from patients referred to Bradford Royal Infirmary for cataract surgery.
Current spectacle prescription data will be obtained from optometrists' referral reports. Previous spectacle prescription data will be obtained from focimetry(measuring)of previous spectacles, copies of previous prescriptions or by asking the patients’ optometrist to provide a copy of the prescription. These spectacle prescriptions will be recorded to the nearest 0.25DS, 0.25DC and 2.5 degrees.
All participants will be asked to complete the short form of the Dizziness Handicap Inventory (DHI(sf))twice: The first time asking them to answer the questions for the present time and the second time asking them to consider how they felt in the two months following the acquisition of their last pair of spectacles.
Changes in spectacle prescription will be statistically analysed.
Data collected from the spectacle prescription changes and DHI(sf) will be used to determine whether there is a link between large changes in spectacle prescription and dizziness.REC name
