Custom IOL Selection That Determines Vision Quality | Gangnam SMILE PRO Vision Correction

Premium IOL

Lens and IOL

The lens is a transparent structure in the front of the eye made of water and protein.
It naturally adjusts thickness to focus light on the retina.

With age, elasticity decreases and clouding causes presbyopia and cataract.

Lens

IOL

IOL is a replacement for the clouded lens.
During cataract surgery, the clouded lens is removed and
replaced with an IOL. Focus range and vision quality vary
by lens type.

First Eye uses only
world-class verified lenses
for presbyopia correction and cataract surgery.

We use products from global optics companies like Johnson & Johnson, Alcon, Zeiss, Hoya, and participate directly in product development and marketing consulting.

First Eye Premium
IOL Custom Consulting

First Eye comprehensively analyzes individual vision, occupation, lifestyle, and comorbidities to recommend the best IOL.

Monofocal IOL

Focus on one distance only (far or near)

Clear at one distance only (far or near)
Reading glasses/glasses needed
Standard cataract surgery

Only for low astigmatism. High astigmatism requires glasses for clarity at any distance

Multifocal IOL

Vision improvement from near to far

Clear vision at all distances
No glasses needed
Presbyopia correction cataract surgery
(myopia, hyperopia, astigmatism, presbyopia all correctable)

Multifocal IOLs are designed to see far and near simultaneously
correcting both cataract and presbyopia.
