What is presbyopia?
It is an age-related nearsightedness problem that occurs in people over the age of 40. The lens inside our eyes has a structure that can change shape. Thanks to this special ability, this lens changes its shape by swelling when objects come close and improves the quality of vision. This is how near vision occurs. After the age of 40, the eye gradually loses this ability and the elastic structure of the natural lens within the eye begins to deteriorate. This partially prevents the changes that occur inside the eye during focusing in near vision.
What is a trifocal lens? To whom does it apply?
Some people use separate glasses for both near and far vision. Some people can see both near and far with a single pair of glasses. A trifocal lens is an intraocular lens that has the ability to see both near and far. Trifocal intraocular lens placement technique is completely a cataract surgery. We apply the same procedures in trifocal lens surgery as we do in standard cataract surgery. In this surgery, the patient's natural lens in the eye is removed and replaced with a lens that is suitable for the internal structure of the eye and will improve the patient's vision. Unlike this surgery, instead of placing a standard lens (which only shows distance, requiring glasses for near vision), a trifocal lens (which shows both near and far) is placed into the eye.
What are their advantages?
Trifocal lenses are lenses that have focusing features that can be called near-far and middle distance, depending on their design. This technology has been used around the world for many years, but very successful results are achieved with the new generation of advanced technology lenses we use today. The lenses inserted in these surgeries remain in the eye for life. In other words, it is not a lens like a contact lens that patients put on and take off. It is placed inside the eye by the physician. It is not possible for the lens to cause allergies or not be accepted by the tissue.
To whom should trifocal lenses be applied?
Patients with cataracts can use these lenses if their eye structure is suitable after a detailed examination. Not every patient's eye may be suitable for this type of surgery. cataract The professional position, age, social activity, reading habit and intellectual level of patients with diarrhea are also important in patient selection. People who do not have cataracts and want to completely eliminate glasses from their lives can also do their daily routine without glasses, thanks to trifocal lenses. It is very important to inform the patient in detail before this surgery. Both the patient and the physician will get the best results from this surgery, which will be performed with appropriate patient selection, appropriate technique, the experience of the institution and physician where the surgery is performed, and of course the correct lens selection.
What affects success?< br /> Lens selection and correct application are the most important aspects of this surgery. Determining exactly the type and degree of the lens to be applied to the patient's eye, the angle at which it will be placed on the eye, and the lens number according to the measurements (which can correct both astigmatism, distance and near vision) is an important and experience-requiring application. Eye protection is provided by using drops for a while after the surgery. These drops should be used and the eyes should be protected for approximately 3-4 weeks.
When will the return to normal life occur?
2-3 days after the surgery, almost all patients will be treated daily. can return to home and work routines.
