The quality of vision depends on age, state of health, type of activity, therefore, its quality may change throughout life.
Volodymyr Melnyk, an ophthalmologist of the highest category, ophthalmic surgeon, candidate of medical sciences, chief physician of the VISIOBUD clinic
, told how monofocal and multifocal intraocular lenses can improve the quality of vision at any age .
Advantages and disadvantages of monofocal and multifocal intraocular lenses
90% of all information we receive thanks to sight.
That is why, when vision deteriorates, there is a desire to improve it.
Intraocular lenses or artificial lenses are used for such diseases as, for example, cataracts and if there are no irreversible changes in the eye.
An intraocular lens is a special implant lens that is installed in place of the cloudy natural lens.
According to the mechanism of vision correction, there are two main types of intraocular lenses that are used in modern ophthalmology - monofocal and multifocal.
Monofocal or single-focal intraocular lenses
provide maximum quality of vision exclusively at a short or long distance.
Therefore, they are suitable for the treatment of cataracts, correction of high degrees of myopia, farsightedness or astigmatism.
But, if you have been fitted with an artificial monofocal artificial lens, you will have to use glasses for reading.
Multifocal or multifocal intraocular lenses
provide clear vision at any distance without glasses.
However, they can create so-called "optical phenomena" related to the peculiarities of the structure of the artificial lens.
These are the effects of glare, halos and stars around light sources that become more noticeable at night.
But there are modern multifocal intraocular lenses
have a smooth transition of focus without "optical phenomena".
Thanks to this, the images are clear and bright, and there is no need to wear glasses.
They absorbed the positive characteristics of single-focal and multifocal intraocular lenses.
Choice of intraocular lenses
Despite the obvious advantages and disadvantages of both types of intraocular lenses
the choice of an artificial lens depends on the individual characteristics of each patient.
structures of the cornea of the eye;
the degree of visual impairment in one eye or in both at the same time;
visual load during the day;
wishes regarding the quality of vision, for example, improving vision without the need to use glasses;
age of the patient.
Selects an artificial lens
an ophthalmologist after a comprehensive examination on professional equipment.
But in any case, the prospect of installing either a monofocal intraocular lens or a multifocal one should not scare you.
The operation lasts from 5 to 20 minutes.
Does not require a stay in the clinic or for a long time
rehabilitation period, which requires wearing bandages, restriction of motor activity, "falling out" from the usual rhythm of life.
Vision improves almost immediately after lens replacement.
So, if you have trouble seeing in the distance, read books with a magnifying glass, suffer from the "foggy glass" effect or decrease in color sensitivity, make an appointment with an ophthalmologist.
Do not rush to buy moisturizing drops on the recommendation of a friend, vitamin complexes or glasses.
Without knowing the exact cause of the deterioration of the quality of vision, you will either not affect the situation in any way, or you will harm yourself, complicating further treatment.
For example, an overripe cataract increases the risk of developing glaucoma or complications during lens replacement surgery.
Make it a rule to check your vision once a year, do not ignore the symptoms of vision deterioration and trust doctors.
It is better to undergo a diagnosis in a timely manner, get answers to all the questions that bother you, and continue to live calmly, than to ignore the development of the disease.
