Investigation into enhanced patient consultation on post-cataract surgery patient satisfaction with visual outcomes

Project Details

Description

Cataract surgery offers an opportunity to correct pre-existing refractive error and surgeons can accurately plan post-operative ocular refractive power1. Current NHS guidelines aims within 0.50-1.00D of emmetropia2 (achieved for 95%3) looking for clear unaided distance vision. Despite the manipulation of refractive correction involved, unlike other refractive procedures, little attention is given to the impact of a large and sudden change to the overall refractive status and little evidence surgeons are encouraged to aim for anything other than emmetropia4. Anecdotal evidence from practitioners suggest some (myopic) patients, would prefer under correction to maintain clear unaided near vision they are accustomed to. However, this is not routine despite guidance to this effect in both Ophthalmologist and Optometrists standards5,64. Recent increase in the assessment of patient satisfaction with their post-operative outcome7-13can be utilised to inform this trend

Executed in two phases (first informs the second), this project aims to establish an evidence base to inform best practice regarding patient consultation around correction prior to cataract surgery. (1) An assessment of patient satisfaction with post-operative visual correction with current guidance; (2) An intervention using an enhanced patient consultation to tailor the target post-operative refractive error to the patient’s needs. This PhD project will provide essential pilot data as required to plan a future cluster design RCT. The student will establish the feasibility of delivering and assessing this intervention and directly assess the impact of patient consultation on post-operative refractive error on newly pseudophakic patients’ visual comfort and satisfaction.

Aims:
1. To determine the myopic patient satisfaction with visual outcome after standard cataract surgery.
2. To assess the feasibility of delivering an enhanced patient consultation and intervention within an NHS setting

Setting:
Ophthalmology Department, Hairmyres NHS University Hospital, Lanarkshire*

*The supervision team is working closely with consultant ophthalmologist Mr Douglas Lyall (NHS Lanarkshire), who will be acting as the key surgeon for the project. We also have support from NHS Lanarkshire R&D department
