Types of Lenses

There are many types of lenses and the best option for you will be discussed during your consultation. A series of diagnostics tests determine the exact specifications for your bespoke lenses. We will also look at your lifestyle and visual requirements.

ICL Treatments

EVO by Staar ICL

The EVO by Staar ICL (Implantable Contact Lens) is Optimax’s lens of choice for this procedure, offering excellent results for those with hyperopia and moderate to high myopia. More than 500,000 implants have been performed world-wide. The lens is made from a soft collamer material and is implanted in the posterior chamber which makes it invisible in daily life. The lens can treat pupils up to 8mm in diameter. Visual Acuity can be 20/20 by the next day in 70-90% of patients. The EVO lens can correct your vision without removing or disturbing the natural tissue during the procedure. The procedure can be reversed in the unlikely event that removing the EVO ICL should become medically necessary.

Benefits include high-quality night vision, UV protection and great results for those with thin corneas. The EVO by Staar ICL provides sharp, clear vision with improved depth and definition, with studies showing a satisfaction rate of 99%.

RLE and Cataract Treatments

Monofocal Lenses

Monofocal lenses normally correct for distance vision but can correct for any visual range desired.

These are used for people who don’t mind using glasses for specific tasks, for example; reading glasses in cases where distance vision has been corrected.

Monofocals are particularly good for patients that need sharp distance vision such as professional drivers. They can also be used to achieve Monovision.

Multifocal and Trifocal Lenses

Unlike Monofocal lenses, these lenses could eliminate the need for reading glasses. They are the most popular choice for the correction of presbyopia (the need for reading glasses).

The lenses are more advanced to provide more than one focal point. It splits the light so some is focused for distance, some for near and some is scattered in the eye. This allows the patient to focus on multiple distances simultaneously.

There may be some loss of contrasts and patients may experience haloes at night.

Extended Depth of Focus (EDOF)

EDOF lenses employ a new technology which has recently emerged in the world of lenses. These lenses allow the wearer to increase their range of focus compared to standard Monofocal lenses, but reduce common visual side effects that come with Multifocal lenses, such as haloes and loss of contrast.

EDOF lenses enable clear vision from far distances (around a 100cm) to intermediate distances (around 80cm). The patient might, however, need to wear reading glasses for close work.

Piggyback Lenses

Piggyback lenses are inserted on top of an existing lens, usually after someone has already had Cataract or RLE treatment. The piggyback lens enhances the vision that the RLE lens already provides, allowing the patient to maximise the benefits of their monofocal or multifocal lens.

This type of lens can also be used in the rare event where the results of surgery need fine-tuning. Rather than removing the artificial lens in a more invasive procedure, the piggyback lens can simply be implanted in front of it, modifying the overall visual result.

Toric Lenses

All lenses for ICL and RLE treatments are available in a TORIC version, which can correct astigmatism as well as other refractive errors.

Astigmatism is a condition in which light is unevenly focussed, causing blurred vision at all distances. The condition allows only partial focus on an image, for instance, astigmatism can cause some wheel spokes to appear clearer than others, or make different distances appear distorted and blurry.
