Monofocal lenses only allow focusing at one distance - near, intermediate, or far away. The lenses indicated visual correction of phakia loss after extracapsular cataract extraction.
Such lenses have a single focal length and are often used to correct distance vision. Patients with such lenses need to wear glasses.
Like your eye's natural lens, the IOL focuses light entering your eye through the cornea and pupil onto the retina, the sensitive tissue at the back of the eye that transmits images to the brain via the optic nerve. Most IOLs are made of flexible, bendable materials and are about a third the size of a dime.
Like prescription eyeglasses, your IOL will contain the correct prescription to give you the best vision possible.
The lenses may be the best choice for patients with cataracts in both eyes. A prime lens is a single fixed focal length intraocular lens. The cataract surgeon may recommend using a monofocal lens for near focus, mid-range focus, or distant focus.
There is only one of these three options and the voice will not change after surgery.
Most lenses are about a third the size of a dime and are made from a flexible, bendable polymer. Your lenses, like prescription glasses, will have the necessary adjustments to give you the best vision possible.
After the operation, you may experience some discomfort and visual changes. You need to rest and follow your surgeon's instructions, including using eye drops as prescribed and avoiding strenuous activities. You may also need to wear an eye patch or protective shield.
Your vision may be blurry or hazy immediately after the procedure, but this typically improves over the first few days.
It may take several weeks or even months for your vision to fully stabilize, and you may need to wear glasses for reading or other activities.
Regular follow-up appointments with the surgeon are important to monitor the healing process and ensure that your vision is improving as expected. If your experience any unusual symptoms, such as severe pain, increased redness or swelling, or worsening vision, you should contact your surgeon immediately.
Your vision will be blurred for a few days while your eye heals after seeing your doctor. As the wound heals, your vision will be markedly improved. If you have had the cataract removed, the color will be brighter because the brown or yellow color of the cataract will no longer obscure the appearance of the color.
You will be asked to see your ophthalmologist again within two days of the procedure. Follow-up checkpoint visits will take place at the one-week and one-month milestones to make sure everything is healing as normal.
If a procedure involves more complicated situations, your doctor may want to see you more often.

The exact amount of time you should plan to be in Turkey before a monofocal lens procedure will depend on several factors, including the specific procedure you are having, your health and healing, and the instructions of your surgeon.
In general, you should plan to be in Turkey for several days before the procedure to allow for a comprehensive eye exam and preoperative planning, as well as time for recovery and follow-up appointments.
The amount of time you should plan to stay in Turkey for a monofocal lens procedure will depend on several factors, including the specifics of your procedure, your health and healing, and the instructions of your surgeon. In general, you should plan to stay in Turkey for 3 days.
Multifocal contact lenses include multiple prescription strengths in a single contact lens to correct vision at multiple distances (eg, near, medial, and distal). In other words, you can think of multifocal contacts as all-in-one contacts for reading and measuring distances (and everything in between).
A Varifocal lens is a type of multifocal lens whose optical power changes gradually. Unlike bifocals, there are no noticeable differences inside the lenses or leaps between readability and distance vision. Progressive lenses have been designed to provide better focusing at medium distances.
People sometimes worry that wearing multifocal lenses means having to wear them all the time – but that's not true. Even people who only need to wear glasses for near vision — reading, iPads, phones, and computers — can wear their contact lenses for those activities and then remove them when they're done.
The majority of patients who have received a corrective or multifocal IOL are still satisfied with their lens of choice more than 5 years after the initial surgery. Glare and halos were still more noticeable in patients who had used multifocal lenses.
If someone has eye disease in either eye (eg, severe dry eye, irregular astigmatism, epiglottitis, macular degeneration), they are not eligible for a multifocal IOL.
Unlike multifocal contact lenses, they don't require regular maintenance or replacement, they last forever! Many patients who wear multifocal intraocular lenses find that they do not need glasses after cataract surgery, or if they do, they can simply wear reading glasses for younger adults.
Wearing multifocal lenses as often as possible will help your eyes move easily between different lens powers. Most people can adapt to multifocal lenses within a week or two.
Once you've acclimated your lenses, wearing them part-time shouldn't be a problem. An exception to this is: You shouldn't go with your numbers until you're comfortable with them. Usually, after a day or two, there is no problem.
It may take three days, three months, or six months for patients to adapt to these lenses. However, some patients may never adapt. In such a case, we should be ready to change a multifocal or EDOF lens for a monofocal lens.
If your eyes require prescription reading (with or without distance correction), then you may be a good candidate for multifocal contact lenses. What is farsightedness? People over 40 often begin to notice that focusing on things up close becomes difficult or impossible and their near vision becomes blurred.
