Egepol Hospitals Eye Diseases and Health Specialist Op. Dr. Emrah Mat said that Trifocal (three-focus) intraocular lenses, commonly known as 'Smart Lenses', provide great ease of vision at all distances.
Op. Dr. Emrah Mat stated that 3-focus Trifocal lenses are preferred by patients who have developed cataracts in their eyes and want to see far, middle and near distances comfortably.
Op. Dr. Mat stated that trifocal lenses also reduce the need for glasses, “Thanks to trifocal lenses, which have three different focal points near, middle and far, we can treat both the patient’s cataract and vision defects at the same time. Sometimes, we can also apply it to people who do not have cataracts but have visual impairments and do not want to wear glasses. In order to use trifocal lenses, the front and back structures of the eye must be absolutely healthy. The patient must not have any additional eye problems such as glaucoma or macular degeneration. If such conditions exist, they can limit the operation,” he said.
CUSTOM LENS IS DETERMINED
Op. Dr. Emrah Mat said: “First, we determine the patient’s vision level and examine the back of the eye. We also measure the eye lens and determine the number of the smart lens that will be placed in the patient’s eye and stay there for life. Here, the lens number is determined by looking at the patient’s astigmatism, cornea, and the length of the front and back axes of the eye. These measurements vary from patient to patient. We determine a lens number that is suitable for the patient’s eye, that is, personalized. Cataracts may not have developed in both eyes. We perform surgery on whichever eye is needed. We do not prefer to perform surgery on both eyes on the same day. Since time is limited for patients coming from abroad, we perform their surgeries one day apart, and for our domestic patients, we perform surgeries one day to one week apart.”
CHOOSE A SPECIALIST PHYSICIAN
Providing information about trifocal lens surgery, Op. Dr. Emrah Mat continued as follows: “Our intraocular lens is a transparent tissue. These lenses can generally lose their transparency between the ages of 50-70. It is more common in some metabolic diseases or those exposed to external factors such as the sun. Malnutrition can also cause cataracts to appear earlier. Cataract surgery is performed with topical (drop) anesthesia. We melt the lens that has lost its transparency inside the eye with ultrasonic energy and remove it from the eye. We also place the Trifocal lens in the space where the lens was previously located. This lens remains fixed in the patient's eye for life. The surgery takes approximately 15-20 minutes. We discharge our patients on the same day. They can open their eyes when they go home. We ask patients to use drops at a decreasing frequency for the first month. Their vision may be blurry for the first few days. Then it improves day by day. They can return to their daily lives in a few days. Surgeries performed by specialist physicians and on suitable patients yield successful results.”
