Close-up, intermediate, and distance vision are all corrected with trifocal lenses.
You may be more accustomed to correcting for long and near distances, but you most certainly utilize your intermediate vision rather frequently. When you gaze at something from a few feet away, such as a computer screen, you are employing intermediate vision.
As you become older, you may need to correct all three types of eyesight. This is possible with trifocal glasses and some types of contacts.
Traditional contact lenses can be used to correct some, if not all, of your vision, needs if you need trifocals.
There are several ways to correct the two types of vision if you need help seeing far and near.
You can wear bifocal contact lenses that combine these types of vision correction in one contact lens. Or you can switch between two different types of contact lenses - one for distant objects and one for near objects.
Bifocal contact lenses don't address intermediate vision correction, but you can wear a pair of glasses to help with that vision when needed.
Another type of lens is one that your surgeon implants directly into your eye. These are called intraocular lenses or IOLs. Intraocular lenses are often used to replace the natural lens of the eye in people with cataracts.
Trifocal intraocular lenses are a recent development in vision correction. They are made of synthetic materials, such as silicon or plastic, and have different zones on the lens to correct different types of vision. They also protect your eyes against ultraviolet rays.
First, our patient underwent a comprehensive eye exam. We then determine the number of lenses to use in the patient's eye with a device that detects them without touching the eye. This method, which we already use in our hospital, ensures that trifocal lens surgery is healthier. In measurements made by touching the eyes, the margin of error is quite high.
After surgery, you may be sensitive to light and feel like something is in your eye. You may feel some discomfort after the procedure. Your doctor may prescribe pain medication to make you more comfortable for the first few days after surgery. You should contact your ophthalmologist immediately if you experience severe pain.
You should see your ophthalmologist the day after surgery. Your doctor will remove the patch and/or protective layer and check your vision and eye condition. Your doctor will explain how to use the eye drops prescribed to you after surgery.
You'll need to take these drops for a few weeks after surgery to reduce inflammation and help prevent infection. Your doctor may ask you to continue wearing the shield day and night or just overnight.
Your vision may be slightly hazy or hazy for the first few days after surgery. Your vision should start to improve after the first few days but may continue to fluctuate over the next several weeks. It usually takes about 2-4 weeks for vision to stabilize.
DO NOT rub your eyes, especially for the first 3-5 days. You may also experience sensitivity to light, glare, starbursts, or halos around lights, or the whites of your eyes may appear red or bloodshot. These symptoms should ease as your eyes heal over the next few weeks.

It is typically recommended to arrive in Turkey for the operation at least 2 days in advance. This will give you enough time to adjust to the new environment and to prepare for the procedure.
We recommend a length of stay in Turkey after the operation is typically 1-2 days. This time is needed for post-operative care, monitoring of the healing process, and follow-up appointments with the surgeon.
Trifocals correct for near and far vision, but also allow a person to see at an intermediate level (about your arm's length). The trifocal lens helps correct the center area by highlighting a second small lens segment just above the area used for near vision correction.
Trifocals have three separate prescriptions on the lenses, indicated by lines, to correct far, intermediate, and near vision. Progressive lenses blend prescriptions so there are no lines on the lenses.
Trifocal contact lenses are generally recommended for people over the age of 40 who have pre-existing vision problems and are beginning to develop presbyopia. But anyone who needs help with all three fields of view can benefit from trifocals.
Trifocal lenses include an additional ribbon-like segment just above the near segment. The power in this section is used to view objects in your immediate viewing area, which is about 18-24 inches.
According to a 2017 literature review that compared the clinical performance of the two lenses, trifocals have been shown to provide better intermediate vision than bifocal multifocal lenses.
Trifocals often cost more than regular prescription glasses designed to correct a vision problem (farsightedness, nearsightedness, or astigmatism). But they are cheaper than most progressive lenses. The average cost of a trifocal lens ranges from $120 to $200.
Bifocal lenses allow a clear distinction between a far and near vision in the lens. While many people immediately choose progressive lenses, bifocal lenses may be a better fit for your lifestyle and vision needs.
Monofocal lenses provide focusing for a single distance. But multifocal lenses allow vision at various distances. These can correct both near, medium and long distance. It is also a more popular option for those who want to eliminate the addiction to glasses.
Nausea and dizziness are more common with bifocal, trifocal, and multifocal lenses, but can occur with all lenses.
Adaptation phase. It can take up to two weeks to adjust to the combination adjustability of your new glasses. Wearing glasses all the time can help you adjust faster. If you continue to have problems after two or more weeks of continuous wear, try seeing your optometrist or optometrist.
