Understanding Cataracts
A cataract is a clouding of the natural lens that can occur with aging, certain medical conditions and trauma. Cataracts may cause blurred vision, dulled vision, sensitivity to light and glare, and/or ghost images. If the cataract changes vision to the extent that it interferes with your daily life, the cataract may need to be removed. Surgery is the only way to remove a cataract.
Cataracts cannot be treated with medication or corrected with glasses. When the cataract impair vision to a degree where it negatively affects daily life, the only effective treatment is to surgically remove the cloudy lens (cataract extraction) and replace it with an implant, a so-called intraocular lens (IOL) Cataract surgery is regarded as safe and reliable. In fact, it is the most frequently performed surgical procedure in the world. During the operation, the natural clouded lens is permanently replaced with a very small artificial lens (IOL). This procedure is well-established and constantly evolving with new technology: for example, new types of intraocular lenses, and more precise devices for diagnosis and imaging.
Introducing Trifocal IOL Surgery
During cataract surgery, the clouded natural lens is removed and replaced with an artificial lens known as an intraocular lens (IOL). At EuroEyes, we offer Trifocal IOLs, which not only replace the cloudy lens but also correct vision at three different distances: near, intermediate (for tasks like computer use), and far. This makes it an excellent option for patients looking to restore clear vision without the need for glasses after surgery.
The procedure is quick and painless, typically performed on an outpatient basis. Once the new lens is in place, it provides sharp focus across all distances, offering long-term visual clarity and freedom from cataracts.
How Does Cataract Surgery Work?
Cataract surgery is a precise and safe procedure. Using ultrasound or laser technology, the clouded lens is gently broken apart and removed. The trifocal intraocular lens is then implanted in its place.
This procedure is minimally invasive, done in topical anesthesia and generally takes only 15 minutes. Most patients experience significant improvement in their vision within just a few days, with complete recovery typically within a few weeks.
Cataracts Surgery Treatment Steps
1. Preparation of the Eye
The surgery is performed on an outpatient basis and usually takes 15 minutes per eye. Before the procedure, the eye is anesthetized with drops so that the patient does not feel any pain during refractive lens exchange. The eye is opened with a tiny corneal incision, which heals seamlessly.
2. Removal of the Lens
The anterior lens envelope is opened in a circular fashion. Then the lens core is removed. The rest of the lens envelope remains and serves as a ‘holding apparatus’ for the new lens.
3. The Trifocal Lens
Each patient receives a trifocal lens that is ideally adapted to his or her individual needs. This well-tolerated artificial lens can remain permanently in the eye and is not visible.
4. Implantation of the Trifocal Lens
The surgeon inserts the new lens into the eye with an injector. The lens unfolds and is properly placed in the empty lens envelope by the surgeon. The trifocal lens corrects Cataracts in addition to other existing vision disorders (near-, farsightedness and astigmatism).
1. Consultation and aptitude Test
- Measurement of all relevant eye parameters
- Diagnosis whether you are suitable for cataract surgery
- In-depth consultation
2. Preliminary medical Examination
- Intensive preliminary ophthalmological examination and measurement of your eyes
- Detailed treatment explanation by a medical specialist
- Duration of examination usually 2 hours
- Before this appointment you are not allowed to wear soft contact lenses for one week and hard contact lenses for two weeks
- You will receive an aftercare kit for the days following your treatment. The contents and medication will be explained to you in detail by our staff.
3. On the Day of your Treatment
- Please bring someone to accompany you
We recommend that you wear comfortable clothing - Please refrain from wearing perfume and make-up on the day of your lens treatment
- You can eat and drink regularly on the day of treatment, please do not smoke.
- The total duration of this outpatient surgery is 15 minutes per eye.
- The operated eye is protected by an eye bandage until the next day.
- By the way: If it is about both eyes, we usually treat them on two consecutive days.
4. After Your Lens Surgery
- Please do not rub your eyes
- Apply eye drops several times a day as directed by a doctor
- Use artificial tears as needed
- Professional activity after 2-4 days
- Resume sports: after about 1 month
- Controls are usually: after 1 day – 1 week – 1 month
- Driving a car is allowed again only after permission of the doctor
The properties of the latest generation of lenses are outstanding and offer the highest quality
We use trifocal lenses of the latest generation.
They have patented high-performance optics and open up the possibility for you to see everyday life clearly without any aid, providing high quality near, intermediate and distance vision.
The Trifocal Premium lenses are manufactured with computer-controlled diamond tools.
This means the highest possible precision and optical premium quality for you.
The optics of the lenses are manufactured using the patented SMP technology:
A special process reduces stray light phenomena, which always occur with trifocal lenses, to an absolute minimum. The positive effect: less glare and fewer halos! Aspherical optics provide optimized image quality and improved contrast vision.
Lenses protect the sensitive retina and are optionally equipped with an extended light protection filter in addition to a UV filter.
This protective function is used in ophthalmology, especially for the prevention of macular degeneration (AMD). No matter whether presbyopia or cataract, whether nearsightedness, farsightedness or astigmatism, clinical studies show that 97% of people operated on no longer need glasses after implantation of trifocal and multifocal lenses.
Difference Between Monofocal and Trifocal IOLs
Key Differences:
- Single-distance correction vs. multifocal correction: Monofocal IOLs correct vision at one distance, while trifocal IOLs provide clear vision at near, intermediate, and far distances.
- Glasses dependency: Trifocal IOLs significantly reduce the need for glasses, while monofocal lenses often require glasses for tasks like reading or driving.
Diagnosis and symptoms of Cataracts
-
- Vision deteriorates in near and/or distance vision: Vision becomes more strained.
- Vision becomes increasingly blurred: Vision feels like looking through fog or a veil.
- The vision of colours, contours and contrasts deteriorates: everything becomes dull and pale.
- Glare sensitivity (nyctometry) increases: When light hits the retina, for example from oncoming traffic while driving at night, vision is severely impaired.
- Light-dark adaptation worsens: It takes longer and longer to become accustomed to changing between light and dark environments.
- Double vision is perceived: One suddenly sees double, similar to alcohol consumption.
- Spatial vision (stereopsis) deteriorates: Due to poor depth perception, for example, falls are more likely and climbing stairs becomes a challenge.
- Cataracts become visible: A grayish or whitish clouding can be seen on the lens.
In addition to cataract, visual impairments such as age-related macular degeneration (AMD) can also occur around the age of 70. Regular ocular fundus checks must therefore be taken very seriously. Now you can do the self-test with the Amsler grid: Macular Degeneration (AMD) self-test.
