Eye Trifocal lenses are intraocular lenses that provide clear vision without glasses at far, middle and close range. While single focal lenses that clarify only distance vision require the use of near-eye glasses, these lenses are trifocal (trifocal). Moreover, thanks to these focuses, they eliminate the need for glasses. Thus, patients can be distant (watching TV, seeing the scene in the theater and theater, driving), medium (using a computer or tablet, cooking, seeing the speed chart while driving, reading barcode in markets), and close distance (using a phone, doing handicrafts). They can do their activities without glasses. In this way, the quality of the patient's life who can see every distance clearly without glasses increases significantly.
To Whom and How to Attach a Trifocal Lens?
Trifocal lenses can be applied to patients who are 50 years of age or older with cataracts or who have distant and/or near vision problems and do not want to wear glasses, whose eye structure is suitable for these lenses. In addition, there are models that correct this visual defect in patients with astigmatism. Just as astigmatism is corrected while wearing glasses, if a smart lens is to be used during cataract surgery, astigmatism must be corrected.
In cataract surgery, the natural lens of the eye is removed and a trifocal lens is placed instead. These lenses are lifetime. The surgical technique applied while wearing these lenses is cataract surgery performed with the phacoemulsification method, which has the highest success rate in the world. It is made with drops, and a mild sedative is applied to patients who wish. Patients are discharged after surgery.
