Presbyopia Lens Implantation, Presbyopic Cataract Lens Type Recommendation

Hello, this is Gangnam Smile Eye Clinic 😊

As the weather cools down, post-operative care for surgery becomes relatively easier,

so many people inquire about eye surgeries.

Among them, the most frequently inquired surgery is presbyopic cataract surgery.

Presbyopic cataract surgery involves removing the existing lens affected by presbyopia and implanting an artificial intraocular lens.

The process of selecting the lens type through consultation with a professional optometrist and ophthalmologist is essential.

However, there are many different types of lenses,

and those visiting an eye clinic for the first time are often overwhelmed.

Usually, a professional counselor who is an optometrist and the ophthalmologist performing the surgery explain and conduct the consultation,

but because there are so many types and features of lenses,

Many people worry that they might mistakenly choose an expensive lens without knowing anything during the consultation.

So today, we will learn about the types of cataract lenses and

how to find the right lens for you.

Lenses can be broadly categorized into three types: monofocal, multifocal, and premium monofocal (extended depth of focus).

What is a monofocal lens?

First, a monofocal lens, as the name suggests, has a single focal point.

Because it focuses on only one distance among many focal points such as far distance, intermediate distance, and near distance,

vision at distances not focused on will not improve after surgery.

This means that with a monofocal lens, glasses may still be required depending on the situation after surgery.

Generally, presbyopic cataract surgery focuses on distant vision,

so glasses are needed for intermediate or near vision depending on the situation.

Therefore, a monofocal lens might be inconvenient for those with hobbies or professions that frequently require near vision.

What is a multifocal lens?

Multifocal lenses can improve vision from near to far distances.

The big advantage is that you can see both near and far,

allowing you to live without glasses.

Since there are multiple focal points, light enters from various directions,

which can cause some glare, and consequently, a slight reduction in resolution.

However, for those who have worn glasses for a long time or

whose cataracts have progressed significantly, resulting in poor vision quality,

the ability to live with clear vision without glasses provides immense satisfaction.

The cost is relatively higher compared to monofocal lenses.

Premium Monofocal / Extended Depth of Focus

The intermediate step that is often considered is premium monofocal,

or extended depth of focus.

This works by extending the depth of focus to provide clear vision at intermediate distances,

compensating for the drawback of traditional premium monofocal lenses that could only focus on one point.

Premium monofocal lenses can be described as intraocular lenses specialized for everyday intermediate distances.

Everyday intermediate distance refers to the most commonly used vision in daily life.

For example, shopping, exercising, cooking, navigation, watching TV, etc.

It can be said to be the most necessary distance in modern life.

Additionally, premium monofocal lenses are also financially

less burdensome than multifocal lenses,

making them a preferred choice for many.

Previously, the 'Tecnis Eyhance' intraocular lens was widely used,

but recently, an upgraded version of Eyhance, the 'Tecnis PureSee', has been released.

Tecnis PureSee

further improved near vision compared to the existing Eyhance lens.

While the existing Eyhance corrected only far and everyday intermediate distances,

the PureSee lens also compensates for everyday near distances of about 50cm,

securing vision even closer to daily life, such as for smartphones.

Furthermore, by using a refractive lens, it not only reduces glare,

but also blocks purple light, such as LED light from phones or headlights from cars,

further minimizing glare.

Improving color difference so that any light

is accurately focused on the retina, resulting in vivid colors,

and enhancing the quality of vision is also a significant advantage.

However, as presbyopic cataract surgery is a delicate procedure performed on the eyes,

it is important to choose comprehensively, considering individual eye characteristics, lifestyle, and medical history,

rather than insisting on superficial factors like Gangnam cataract costs.

For example, whether the patient's axial length is not too short for the lens,

whether they have a pupil size sensitive to glare,

etc., to assess individual eye characteristics,

it is crucial to visit a hospital equipped with professional examination equipment

and analyze accurate test results.

It is also important to comprehensively consider whether one has a profession or hobby that requires both near and far vision.

Our Gangnam Smile Eye Clinic

is equipped with university hospital-level medical and examination equipment

and a systematic examination/surgery system,

always treating each individual with sincerity

during examinations and surgeries.

We also always prioritize the patient

and place transparency and safety first.
