A Monofocal Lenses may be the best option for patients who have cataracts in both eyes. A monofocal lens is an intraocular lens with a single fixed focus. A cataract surgeon may recommend monofocal lenses for near focus, mid-distance focus, or distant focus. Only one of these three options is available, and the focus will not shift following surgery.
Lenses, like your natural lens, concentrate light that enters your eye through the cornea and pupil onto the retina, the sensory tissue at the back of the eye that communicates images to the brain via the optic nerve. Most lenses are around one third the size of a dime and are constructed of a flexible, foldable polymer. Your lenses, like the lenses of prescription eyeglasses, will have the necessary prescription to provide you with the greatest vision possible.
Advantages of Monofocal Lenses
- If you have astigmatism, you may be able to have it corrected with a toric/enhanced monofocal lens, which may improve your vision more than a standard monofocal lens.
- If you still need glasses following your operation, you may find that you have better low light vision than you would have had if you had chosen multifocal lenses.
Monofocal Lenses Have the Following Disadvantages:
- If you choose to increase your distant vision, you will still require reading glasses. This also works in reverse: if you have opted to improve your short sightedness, you may need to wear distance glasses, such as when driving.
- If you have astigmatism then choose a typical monofocal lens, you may find that your vision is still fuzzy and that you suffer from short or long sightedness.

How to Make Monofocal Lens?
Monofocal intraocular lenses were the most commonly used kind of lens for decades. They are now, however, the most basic remedy for cataracts on the market. They are intended to correct eyesight at a certain location in space: distant, moderate, or close. Light rays enter the optic system of a monofocal lens and converge on a single point of focus on the retina.
When calculations are performed for distant objects, the intraocular lens can only concentrate on these things. In contrast, if close up focus is desired, the lens’s power must be raised. A monofocal lens cannot focus on both distances at the same time. Most patients who opt for this type of lens prefer to have good distant vision and rely on reading glasses for near vision.
Methods of Lens Implantation
Ultrasound Guided Surgery (Classic Method)
For decades, traditional lens implantation has used ultrasonic energy to shred and aspirate the lens. All essential cuts in the eye are made in structures that are as thin as 0.01 mm. Because the cuts are made by hand, the surgeon must have a very steady hand. Despite this, the operation is quite safe and has been tried and tested a million times.
Lens Implantation Using a Femtosecond Laser
In lens implantation, a new laser technique has replaced the knife. A femtosecond laser now controls all of the stages that the surgeon formerly did manually with a scalpel.
What are the Risks of Monofocal Lens?
A downside of using a monofocal lens is that only one zone of clear vision can be selected. Most people opt for a monofocal lens for distance vision and reading glasses for near work. A monofocal lens can also be configured for close vision, but glasses or contact lenses are necessary to view objects clearly at a distance. Individuals undergoing cataract surgery or natural lens replacement in both eyes can also benefit from a combination of these two procedures. In this strategy, known as monovision, the monofocal lenses in one eye can be tuned for distance while the lenses in the other eye is set for nearby. While monovision correction can be adapted by 85 percent of people, a tiny number of persons may feel off balance using this strategy.

Should Monofocal Lens be Made in Turkey or in the UK?
Monofocal lenses, in general, correct distance vision, but we can have them made to correct a specific visual distance you desire. Monofocal lenses are appropriate if you still want to use glasses for some tasks, such as reading. If your employment needs you to have exceptional distance vision, for example, monofocal lenses may be a better fit that multifocal or trifocal lenses.
If you want (or are just eligible for) monofocal lenses but also want your distance and reading vision corrected, monovision treatment may be an option. Monovision is a type of lens surgery in which we fix one eye for near sightedness and the other for farsightedness. Because each eye covers its own spectrum of vision, you might have good distance and near vision.
This treatment, however, is not always appropriate for everyone because not everyone can adjust to each eye working over independent distances. That is why, following your appointment, we can give a trial with contact lenses to simulate the ultimate outcomes, allowing you to determine whether Monovision therapy is right for you.
We recommend that you do this in Turkey. Because Turkey is the leading name of medical tourism. Since the result is like this, we recommend you to choose this place instead of the UK.
