This is a vision correction procedure for middle-aged and elderly patients that replaces the cloudy lens with an artificial lens to correct presbyopia and cataracts simultaneously.
Cataracts are a condition in which the lens, which should be transparent, becomes cloudy; as the condition progresses, surgery to replace the lens with an artificial one is necessary. In this case, choosing a multifocal artificial lens corrects both cataracts and presbyopia simultaneously, allowing for clear vision at near, intermediate, and far distances, making it a key option for vision correction for middle-aged and elderly individuals.
Monofocal lenses focus on a single distance (usually far) for clear vision, but they do not correct presbyopia, so reading glasses may be necessary. Multifocal lenses (bifocal, trifocal, or continuous focus) allow you to see at various distances and correct presbyopia as well. Choose based on your lifestyle and budget.
This is suitable for cases where vision is blurry, or you experience glare or double vision due to cataracts, or if you wish to address both presbyopia and cataracts simultaneously. Presbyopia correction is determined based on the condition of the eye, using various methods such as reading glasses, contact lenses, lasers, or lens implantation.
The cloudy lens is removed using ultrasound, and an artificial lens is inserted. The surgery itself is short and performed under topical anesthesia, and while you can return to your daily activities within a few days, you must be careful to avoid rubbing your eyes, strenuous activities, and infection for 2 to 4 weeks.
Multifocal lenses may require an adjustment period for nighttime glare (glare and halo). Since the most suitable lens varies depending on the condition of the eyes, cornea, and retina, it must be determined after a precise examination.
LASIK and LASEK correct myopia and astigmatism by reshaping the cornea, while presbyopia and cataract surgery resolve both by replacing the natural lens with an artificial lens.
The suitability varies depending on nighttime glare adaptation, eye condition, pupil size, etc., so it is determined after a precise examination.
