PREMIUM INTRAOCULAR
Lens Applications
The loss of transparency of the intraocular lens behind the pupil is called cataract.
Although cataract development is most commonly seen as a natural consequence of aging, it can rarely develop congenitally, due to traumas and medications used. Cataracts can also develop at a young age in systemic diseases such as diabetes.
Cataract surgery is the most commonly performed surgery in the world today, with the need for quality vision increasing with the prolonged human life and technological developments. Once cataracts start to develop, there is no medical treatment to reverse this process. For this reason, what should be done after the complaints start to occur is to remove the lens that has lost its transparency and replace it with an artificial lens. In recent years, the same surgery can be performed to get rid of the use of near and far glasses before cataract development begins. This procedure, called refractive lens exchange, is generally preferred in patients aged 50 and over and is the only treatment for presbyopia, an age-related near focus defect.
Being the most common surgery in the world and thanks to the support of the industry, there have been significant developments in cataract surgery in recent years, both in surgical technique and intraocular lens technology.
Until 20 years ago, this operation, which was performed as a standard procedure and required the use of near and far glasses after surgery, has enabled a life without glasses.
PREMIUM
High Quality Lenses
1
Toric Lenses
Laser technology allows incisions to be made at the micron level. This increases the safety and success of the surgery.
2
Multifocal (Smart) Lenses
The laser is programmed specifically for each eye structure. This results in faster healing and better quality vision.
3
EDOF Lenses
Instead of the blades used in traditional methods, a laser is used, which reduces the risk of infection.
Take Your Vision Quality into the Future!
Toric Lenses
Astigmatism is a refractive error caused by the eye structure that impairs both distance and near vision. Studies have shown that half of the patients in the cataract age group have astigmatism that needs to be corrected.
This defect, which cannot be corrected by standard lenses, can be permanently corrected with toric lenses and the need for distance glasses after the operation is eliminated.
After being on the market for 25 years, the use of toric lenses has gradually increased especially in the last 10 years. Toric intraocular lenses are no different from standard monofocal lenses in terms of optical quality. It does not require an acclimatization process as with spectacle lenses. In this sense, it can be easily applied to every patient with astigmatism above a certain level (0.75D and above).

Multifocal Lenses
Although the industry’s efforts to produce accommodative lenses that work like our natural lens, that is, which can focus near and middle distance with the movement of our eye muscles, continue at full speed, the desired point has not been reached in this regard.
For this reason, today, near vision can be achieved with different optical principles and lens designs. In the 20 years of developing multifocal lens technology, the most preferred lenses today are diffractive trifocal lenses. Diffractive bifocal lenses are not used today because they do not show the middle distance well.
Diffraction is the bending of light as it passes through a rough surface, creating different foci. In diffractive trifocal lenses, light is divided into 3 different foci, near-medium and far distance, in the rings on the lens.
Although the splitting of light creates a clear image in these three foci, it may also cause undesirable effects such as decreased contrast sensitivity, haloed vision and glare. The severity and duration of these unwanted effects, called photic phenomena, may vary from person to person. After a certain adaptation period, the brain adapts to this new situation. The biggest advantage of trifocal lenses is that they permanently eliminate the need for glasses at any distance.
For trifocal lens implantation, the anatomical features of the eye should be appropriate and there should not be any pathology such as advanced glaucoma, yellow spot diseases that may cause visual impairment other than cataract.
Increasing Focus Depth
EDOF Lenses
They are lenses that also contribute to near vision, providing uninterrupted vision between far and middle distance.
Their potential for near vision is lower than that of trifocal lenses. Different designs using different optical principles are used in EDOF lenses.
- PIN HOLE
- SPHERICAL ABERRATION ⎬ PURE EDO
- LOW-ADDITION DIFFRACTIVE LENSES
- HYBRID LENSES EDOF + LOW-ADDITION DIFFRACTIVE
- POWER BOOST OR WAVEFRONT MODULATION IN THE CENTRAL ZONE
The most preferred lenses today are EDOF lenses that work on the principles of wavefront modulation and spherical aberration. The biggest advantage of these lenses is that the loss of contrast and light reflections, which we call photic phenomena, seen in trifocal lenses are much less. EDOF lenses may be preferred in young patients in active working life, in patients who have undergone refractive surgery before, in patients whose anatomical and other features of the eye do not allow trifocal lens implantation. Patients implanted with EDOF lenses do not need glasses for most of their daily activities after surgery, but may need near glasses, even with small numbers, for prolonged reading and in cases of insufficient light.
PREMIUM SMART LENS
Things to be considered in their application!
The only permanent treatment for presbyopia, the problem of nearsightedness that occurs after a certain age, is premium lenses. For this reason, especially for people who want to get rid of glasses after the age of 50, lens replacement is performed instead of Excimer laser and this procedure is called refractive lens replacement since there is no cataract.
Refractive cataract surgery or refractive lens exchange is actually an aesthetic intervention that depends on the person’s preference. As in every aesthetic intervention, it is the patient, not the physician, who should make the decision. The task of the physician is to inform the patient correctly and perform the surgery in the best way.
The issue of which patient should wear trifocal lenses and which patient should wear EDOF lenses is the most controversial issue among doctors today. The decision depends on the presence or absence of cataract, the patient’s eye characteristics, occupation and expectations.
The implantation of near lenses requires certain conditions. In simple terms, these lenses should not be implanted if there is any problem other than number or cataract in the eye. Yellow spot disease, diabetic retinopathy, severe dry eye, corneal dystrophies, keratoconus, optic neuropathy, advanced glaucoma etc. are the conditions in which smart lenses should not be implanted.
If the eye structure is suitable, your physician calculates the power of the lens to be inserted into the eye by making many calculations. If your astigmatism is above a certain level, toric lenses should be preferred because the most important reason for patient complaints after surgery is the presence of a small number in the eye.
Since the implanted lens will remain in the eye for a lifetime, the quality of the lens material is very important.
The refractive status after both trifocal and EDOF lens implantation is permanent. Cataract does not develop again, the need for glasses does not increase or decrease over time. Nevertheless, an annual eye check-up is necessary for eye health and other eye diseases that may occur.
As a result; there are many factors that can affect the result in premium lens applications, and the result of an optimum surgery performed in appropriate patients makes our patients happy.
