| Scientific title | A prospective randomised controlled trial comparing bilateral multifocal intraocular lens implantation with monovision following cataract surgery |
| Study hypothesis | Null hypothesis: There is no difference in the percentage of patients that report that they never wear spectacles after bilateral implantation with either TECNIS ZM000 multifocal IntraOcular Lenses (IOLs) or Bausch and Lomb Akreos AO monofocal IOLs with the powers of the monofocal IOLs adjusted to give 1.5 dioptres of monovision. |
| Ethics approval(s) | Moorfields and Whittington Local Research Ethics Committee, 18/10/2006, ref: 06/Q0504/82 |
| Condition | Cataract |
| Intervention | Bilateral intraocular lens implant with either TECNIS ZM000 multifocal or Bausch and Lomb Akreos AO monofocal intraocular lenses. |
| Intervention type | Device |
| Pharmaceutical study type(s) | |
| Phase | |
| Drug / device / biological / vaccine name(s) | |
| Primary outcome measure | Percentage of patients with total spectacle independence |
| Secondary outcome measures | 1. Visual Function 14-question (VF14) questionnaire 2. Near visual acuity 3. Reading speed 4. Binolcular Logarithm of the Minimum Angle of Resolution (LogMAR) acuity 5. Binocular Pelli Robson contrast sensitivity - photopic and dark adapted 6. Procyon pupillometry 7. Forward light scatter - van den Berg forward light scatter test 8. Wavefront aberrations - Shack Hartmann aberrometry |

Eligibility
| Participant type(s) | Patient |
|---|---|
| Age group | Adult |
| Sex | Both |
| Target number of participants | 212 |
| Participant inclusion criteria | 1. Patients requiring bilateral cataract surgery with good visual potential and a full visual field in each eye 2. Age range 30 to 90 years 3. Biometry indicating IOL power requirement within the range +10 to +30D for emmetropia (0.00 to -0.50D spherical equivalent) in both eyes |
| Participant exclusion criteria | 1. Patients aiming for a refractive result other than bilateral emmetropia (0.00 to -0.50D spherical equivalant) or emmetropia in one eye and low myopia in the other, i.e., the intended monovision outcome 2. Significant co-pathology (including macular pathology, glaucoma, uveitis, corneal disease, diabetic retinopathy, previous retinal detachment surgery) 3. Keratometric astigmatism 1.5D in either eye 4. Amblyopia 5. Congenital or traumatic cataracts 6. Poor comprehension of written or spoken English 7. Inability to give informed consent 8. Mobility, tremor or postural problems causing discomfort during slit lamp examination |
