Tecnis Eyhance Versus Rayner RayOne Study

Visual and Optical Outcomes After Bilateral Implantation of Tecnis Eyhance Versus Rayner RayOne Aspheric in Patients Undergoing Routine Cataract Surgery

Cataract surgery involves replacing milky lens with a plastic intraocular lens. This plastic lens can be either monofocal (fixates for distance or near without glasses), extended depth of focus (EDOF)(fixates for intermediate and distance vision only without glasses) or multifocal lenses (fixates for distance, intermediate and near vision without glasses). However, EDOF and multifocal lenses are known to produce glare and halos. Tecnis Eyhance (Johnson & Johnson, USA) is a monofocal IOL which give added intermediate vision without employing EDOF or multifocal technology and hence induces no glare and halos. Whereas monofocal IOLs such as RayOne do not give intermediate vision. The objective is to assess visual and optical performance of Tecnis Eyhance versus Rayner RayOne in a prospective, randomized, comparative bilateral study. The proposed study will be the first study comparing the new technology monofocal Eyhance with conventional RayOne Rayner lens to assess the added benefits of Eyhance technology at multiple visits until 3 months after the surgery. Patients attending the clinics with cataracts will be invited to participate in this randomised study. They will be randomised to receive either Eyhance or RayOne in both eyes through surgeries performed not more than 2 weeks apart. The patients will be followed up at 1 and 3 months in the research clinic to assess the uniocular and binocular vision, spectacle prescription, a simple non-invasive scan to look at any distortions in the optics of the eye (wavefront aberrometry) and questionnaire for assessing subjective outcomes, glare and halos.

Detailed Description

Study design:

Prospective, randomised, comparative study assessing visual and optical outcomes after bilateral implantation of the new Johnson & Johnson Tecnis Eyhance versus monofocal Rayner RayOne in patients undergoing routine cataract surgery.

Methodology:

Suitable patients with cataracts in both eyes will be identified from cataract assessment clinics. They will be invited to participate in the study by the research nurse and handed over the patient information sheet and a consent form. The PI will consent the patient for the participation. If they agree to participate, they will be give the dates for their surgeries on the same day. The patients can choose to have both eyes done on the same day or two eyes within 2 weeks based on the patients convenience. If they chose to participate in the study, then the patient will have additional tests performed on the day of their cataract assessment clinic. This will take an additional 40 minutes.

On the day of the surgery, the patients will be randomised using a computer generated randomisation to receive either Tecnis Eyhance or the Rayner RayOne lens. They will have the same lens in both eyes. The patients will be invited for a research follow up visit at 1 (between 30-37 days after 2nd eye surgery) and 3 months (90-100 days after 2nd eye surgery) were simple research tests will performed including vision assessment and a scan.

At preoperative visit and 3 months the patients will be asked to fill in a questionnaire.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Tecnis Eyhance
Tecnis Eyhance hydrophobic IOL is a monofocal IOL with added advantage of slightly better unaided intermediate vision at 60 cms.
Tecnis Eyhance is a monofocal IOL which give added intermediate vision without employing EDOF or multifocal technology and hence induces no glare and halos. Whereas monofocal IOLs such as RayOne do not give intermediate vision.
Active Comparator: Rayner RayOne
Rayner Rayone is a monofocal hydrophilic IOL which is not intended to give better unaided or near vision.
Tecnis Eyhance is a monofocal IOL which give added intermediate vision without employing EDOF or multifocal technology and hence induces no glare and halos. Whereas monofocal IOLs such as RayOne do not give intermediate vision.
