What are intraocular lenses?

The main purpose of refractive intraocular lenses (IOLs) is to serve as a substitute for natural lenses during various eye surgeries, including both cataract and refractive cataract surgery as well as refractive lens exchange (RLE). These lenses come in the form of modelled plastic implants.

Premium intraocular lenses are a natural progression of IOLs that improve the vision of cataract surgery patients by providing visual support at distances both near and far without spectacles.

Nowadays, there has been an improvement in the types of premium lenses available. An ophthalmologist will advise on the right choice of premium IOL based on the patient’s specifications and lifestyle.

What are the different types of premium intraocular lenses?

EYECENTRIC Bukit Tinggi Medical Centre (BTMC) offers a wide selection of premium IOLs formulated with cutting-edge technology and utmost care for the wellbeing of our patients. These are some of the premium IOLs that are offered at EYECENTRIC:

Monofocal IOLS - Monofocal intraocular lenses have a single point of focus that varies depending on the patient’s eye condition – near, intermediate, and distant. As a result, these lenses only provide one focus at a time, which may require the patient to use glasses for reading and computer usage.

Toric IOLs - These are well-built lenses that are designed to correct astigmatism alongside near-sightedness and farsightedness. This is because toric IOLs offer different powers across various meridians of the lens as well as alignment markets on the periphery of the lenses, which allows for adjustments to the orientation of the IOL for optimal vision correction.

Multifocal IOLs - Multifocal intraocular lenses assist in presbyopia correction and reduce the need for reading glasses or computer glasses. These lenses add magnification to distinct spots of the lens to expand the field of vision and provide clearer vision of objects across all distances.

There are also additional premium lenses that are more specialised for certain conditions, such as:

Aspheric IOLs - Premium aspheric IOLs emulate the shape and visual prowess of natural lenses as closely as possible; this means clearer sight for patients with larger pupils as well as in dim-light situations such as driving at night.

Accommodating IOLs - Using flexible “haptics” (supporting legs that stabilise the IOL into the correct position) alongside the aforementioned aspheric design, an accommodating IOL shifts its stance slightly depending on the distance of the object. For example, accommodating IOLs move forwards slightly when observing at nearby objects, resulting in improved close sight compared to normal monofocal lenses.

These IOLs are a great choice for those who additionally deal with presbyopia, an eye condition that causes a steady drop in the eye’s capability to focus on objects close up.

Extended Depth of Focus (EDOF) IOLs - These lenses utilise new technology to counterbalance chromatic aberration of the cornea, which is when eye lenses lack the ability to focus on all colours on the same point. Individuals facing this condition may observe colour distortion when viewing the borders of an object on a photograph.

Patients who deal with cataracts, presbyopia, and astigmatism can benefit from EDOF IOLs due to its ability to improve vision at all distances and mitigates the effects of chromatic aberration. In turn, patients are able to observe colour boundaries that are well defined as well as maintain good vision for computer use and viewing distant objects without glasses.

Choosing the correct premium lenses for better refractive outcomes

Depending on whether one undergoes cataract and refractive surgery, having different types of premium lens in each eye can provide the best possible refractive outcomes.

For example, a patient has greater levels of astigmatism in one eye compared to the other. An ophthalmologist or eye surgeon may advise to get a toric IOL in that eye and an accommodating IOL in the other eye in tandem with one another. As a result, this would rid the patient of the need for computer glasses.

It is highly recommended to consult an eye doctor before any eye-related surgery for a proper eye health check-up. This ensures that both the patient and ophthalmologist are fully aware of the condition of the patient’s eyes and are hence able to choose IOLs based on what is most suited to their needs following the surgery.
