Abstract Details

Purpose:

To report the results of patient reported outcome measures of phacoemulsification cataract surgery using the newly developed Rasch calibrated questionnaire Cat-PROM5 in a multi-ethnic London (UK) cohort. This short instrument, which contains 5 broad questions, was used to evaluate patient perceived benefits following cataract surgery, as improvement of visual acuity alone fails to evaluate the impact of the procedure on patient’s quality of life.

Setting:

Moorfields Eye Hospital, London UK.

Methods:

Patients undergoing phacoemulsification and monofocal intraocular lens implantation aiming for emmetropia, at Moorfields Eye Hospital were recruited prospectively between October 2017 and April 2018. Patients completed the CatPROM-5 questionnaire pre and post-operatively. Post-operative questionnaires were completed at least 3 weeks following surgery. Data of 444 eyes with age-related cataract were included in the cohort and results were analysed using the Rasch scoring.

Results:

Overall improvement of visual disability in our cohort was -5.07 logits [improvement of SE -2.3 Standard deviation (SD 2.2, Sparrow et al)]. These results were in line with visual acuity mean improvement from 0.6 logmar pre-op to 0.15 logmar post op. This improvement was reflected in each of the 6 participated sites when analysed individually. Sub-analysis of different age groups (<65 years old), good presenting visual acuity pre-operatively (< 0.2 logmar) and good pre-op Rasch score (<0 logits) did not reveal any significant difference on patients’ perceived improvement in visual disability.

Conclusions:

This study provides new data suporting Cat-PROM5, as a short 5 item questionnaire, has high responsiveness in reporting improvement in visual disability following cataract surgery in a multi-ethnic London (UK) population. This specific cataract PROM can be readily used in a high-volume cataract setting due to its brevity and broadness of questioning that manages to individually address visual disability as perceived by patients and their carers. The results were in accord when comparing different sites with varying demographics.
