Study summary

This study will investigate the effectiveness of an optometric follow up of cataract surgery versus an ophthalmic surgeon follow up. It will investigate patient satisfaction,safety and cost.

Read the detailed description

The study will be a mixed-methods study, including a randomized controlled trial in which participants are randomized after cataract surgery to follow up to be consultant led follow up or conducted by a trained optometrist 4-6 weeks following surgery. All participants will then return 6 months after surgery for an additional follow-up visit with an ophthalmologist other than the operating surgeon with patient healthcare satisfaction (main outcome), cost-effectiveness and safety outcomes being measured. A subset of patients and local clinicians will also take part in a one-time, individual, semi-structured interview.

This research will test an alternative model of aftercare for cataract surgeries, which may reduce patient waiting time and inconvenience. In turn, this could help improve patient satisfaction and reduce costs for both patients and the National Health Service (NHS).

Participants will be recruited by operating surgeons. The research will take place in the hospital/clinic/optometrists' offices.

Inclusion criteria

  • Patients undergoing cataract surgery in 1st or 2nd eye for age-related cataract, in the Belfast Trust and Southern Trust
  • Willing to participate and give informed consent.

Exclusion criteria

Exclusion Criteria:

  • Patients judged by operative surgeon to be of high risk of loss of visual acuity in the operative eye (e.g. end stage glaucoma etc.). Note that patients with ocular comorbidity and previous surgery will not be routinely excluded, nor will monocular patients.
  • Patients that were not referred by an optometrist.

What researchers measure

Primary outcomes

  1. Patient Satisfaction following different follow up to cataract surgery (Opthalmic led versus optometric follow up)

    Patient satisfaction will be measured using the patient satisfaction questionnaire (PSQ)-18 at 6 months after surgery The scale include values for general satisfaction, technical quality, interpersonal manner, communication, financial aspects, time spent with doctor and accessibility and convenience. Each question is scored between 1 - 5. As some questions have reverse scoring (higher values indicate dissatisfaction) scores are reversed so a 5 will show highest satisfaction and 1 show lowest satisfaction. Each item within the subscales will be averaged and results will be given for each of the 7 subscales

    Time frame: At 6 months

Secondary outcomes

  1. Cost

    The total cost per patient visit will be determined and compared

    Time frame: At 6 months

  2. Patient safety

    Patient safety outcomes in the operative eye will include: loss of visual acuity \>=2 lines Intraocular pressure (IOP) rise \>=8 millimetres of mercury (mmHg) post-operative complications as documented by the examining ophthalmologist.

    Time frame: At 6 months

  3. Intraocular pressure (IOP) rise

    IOP rise will be compared between the 2 groups in mmHg

    Time frame: 6 months

  4. Visual Acuity

    Visual acuity will be compared between the 2 groups

    Time frame: 6 months

  5. Post operative complications

    Post operative complications will be assessed qualitatively. Surgeons at the 6 month follow up will detail if cornea deep and quiet, wound is intact, intraocular lens centred, posterior capsule intact and clear, anterior vitreous quiet, posterior pole and retina remarkable, signs if infection, retained ens matter and other abnormalities recorded by the surgeon.

    Time frame: 6 months

Other outcomes

  1. Adherence

    How well patients that have had cataract surgery follow advice for at home care (use of post-operative medication, self-report) and attending follow up medical appointments (as per patient records) will also be compared between the two groups.

    Time frame: At 6 months
