As we continue to navigate the scale and impact of COVID-19, the health and wellbeing of our staff and patients is always our greatest priority. We have therefore made the difficult decision to stop seeing non-urgent patients but will continue to offer support through video consultations.
Unlike the NHS setting where lens choice is limited, patients having private lens surgery can choose between a broad range of latest technology lenses. These include multifocal, monofocal and toric intraocular lenses. The choice of lens is personal and will depend on your lifestyle, visual needs, recreational pastimes, whether you drive, and also on astigmatism or any existing eye disease. All lenses are premium quality, are CE marked and have undergone rigorous testing to allow implantation. Multifocal lens implants are combined with femtosecond laser cataract surgery for best results. We use the below multifocal lens implants.
The FineVision trifocal diffractive IOL was designed to provide patients with intermediate acuity by using the optical property of constructive interference to capture light energy that other diffractive IOLs lose. In addition to the distance correction, the FineVision lens has 3.5 D power for near and 1.75 D for intermediate vision. It was designed to “overcome the ‘gap’ that is encountered with the bifocal diffractive designs for that specific [intermediate] distance
FineVision’s anterior surface combines two diffractive profiles (one for distance and near, and the other for distance and intermediate), which are microlathed in an alternating pattern from center to periphery. In the same space where other multifocal IOLs have 12 or fewer optical steps, this IOL has more than 30
The AMO Tecnis Symfony extended range lens is the newest lens technology to offer patients greater independence from glasses for distance, intermediate, and near vision.
Some multifocal lenses can causing glare and haloes and can compromise the quality of distance vision in terms of contrast sensitivity and colour vision perception. The Symfony lens has an innovative new design of diffractive rings that results in no loss of distance visual quality whilst allowing unaided intermediate and near vision. Studies of the lens reveals a very low risk of haloes and glare which was comparable to a standard mono-focal lens. The lens showed excellent unaided distance vision in 100% of patients, intermediate vision in 94% and near vision in 87% of patients.
The unique LISA concept…
L Light distributed asymmetrically between distant (65%) and near focus (35%) for improved intermediate vision and greatly reduced halos and glare
I Independent from pupil size due to high performance diffractive-
refractive micro-structure covering the complete 6.0 mm optical diameter
S SMP technology for a lens surface without any sharp angles for ideal optical imaging quality with reduced light scattering
A Aberration correcting optimized aspheric optic for better contrast
sensitivity, depth of field and sharper vision
