What's the Difference Between Presbyopia and Cataracts? Gangnam Cataract Eye Clinic, How to Choose Lens Types
Learn the differences between presbyopia and cataracts, how to choose an eye clinic for surgery, and the right intraocular lens type for your needs.


Hello, this is Gangnam Smile Eye Clinic😊
According to a survey on eye health awareness among seniors by a global ophthalmology specialized company,
8 to 9 out of 10 elderly individuals reported experiencing vision discomfort due to aging.
However, it was found that they did not have accurate information about treatments for age-related eye diseases like cataracts.
In this era of 100-year lifespans, eye health management is essential for maintaining a healthy social life.
Therefore, it seems necessary to provide accurate information about cataract surgery.
So today, we will take some time to learn about:
What is the difference between cataracts and presbyopia?
What are the criteria for choosing a hospital for presbyopia and cataract surgery?
And what are the criteria for choosing the lenses to be used in the surgery?
What's the Difference Between Cataracts and Presbyopia?

Presbyopia and age-related cataracts are often confused
because both cause symptoms of vision deterioration.
In particular, age-related cataracts are often mistaken for simple presbyopia.
Age-related cataracts account for the highest percentage of all cataracts,
and if left untreated, cataracts can lead to various complications.
Therefore, it is crucial to understand the difference and seek early treatment.
First, cataracts refer to a condition where the lens, which adjusts focus based on distance,
becomes cloudy due to various causes.
When the lens becomes cloudy, it cannot properly transmit light, preventing the retina from focusing accurately,
resulting in blurry vision, as if looking through a fog, and decreased visual acuity.
On the other hand, presbyopia is a condition where, with increasing age, the elasticity of the lens decreases and it thickens,
causing objects or text to appear blurry when looking at things up close.
These two symptoms usually begin simultaneously,
with initial symptoms often appearing between the ages of 40 and 50.
Therefore, accurate examination and diagnosis by a specialist are necessary.
How to Treat Presbyopia and Cataracts?
Since the 'lens' is the common structure causing both presbyopia and cataracts,
treatment can be resolved at once with 'intraocular lens implantation surgery'.
Intraocular lens implantation surgery involves removing the existing lens that has become cloudy due to cataracts,
or has lost elasticity and function due to presbyopia,
and implanting an artificial intraocular lens.
How to Choose an Eye Clinic for Presbyopia and Cataract Surgery
As this is a surgery performed on an important organ like the eye,
it is crucial to carefully consider the medical team's clinical experience and technical skills, systematic post-operative care, etc., rather than just the surgery cost.
Choosing the intraocular lens to replace the natural lens
can be said to be the most important aspect of the surgery.

How to Choose a Cataract Surgery Lens

Lenses are broadly divided into monofocal and multifocal.
Monofocal lenses are covered by insurance, so the financial burden of surgery is not significant,
and there is less concern about side effects like glare.
However, they can only focus at one distance (usually far distance),
so glasses are essential for near vision after surgery.
Multifocal lenses can correct vision at all distances, eliminating the need for glasses after surgery,
and are highly preferred as they can also improve presbyopia.
However, since the focus is distributed across multiple points,
problems such as glare or reduced visual clarity may occur.
Rather than insisting on just one factor when choosing a lens,
it is important to consider all aspects, including individual eye characteristics, lifestyle, and medical history.
For example, whether the patient's axial length is not too short for the lens,
whether they have a pupil size sensitive to glare,
whether their retina is not weak,
or whether they have a job or hobby where both near and far vision are important.
These factors should be comprehensively considered.

Therefore, Gangnam Smile Eye Clinic, a Gangnam Cataract Eye Clinic,
has a pre-examination system comparable to university hospitals for precise examinations,
and after thorough 1:1 customized consultations,
we recommend an intraocular lens suitable for each individual's eyes.
