Choose the right artificial lens

There are several types of artificial lenses (called intraocular lenses, IOLs) that we can use during cataract surgery:

Most often used

Monofocal aspheric artificial lenses

Monofocal” means that the artificial lens provides a sharp image at a single distance; everything else is out of focus. If we focus your eye at far distance, you will see out of focus at intermediate and at reading distance. You will need progressive glasses.

Asférico” means that the artificial lens is optimized to provide the most distortion-free vision possible, and the colors and contrasts are brilliant.

The artificial lenses we use are both monofocal and aspheric.

EDOF artificial lenses

EDOF” stands for “extended depth of focus“, which means that this artificial lens does not have a focal point, but rather a focal tube. Thus, this artificial lens provides a brilliant image in the distance and quite a good image in intermediate and reading distance. You can read short texts completely without reading glasses and you can also see the instruments in focus when driving.

These artificial lenses must be perfectly centered during surgery or they will not work properly.

Toric artificial lenses

Do you also have astigmatism? Toric artificial lenses can correct astigmatism.

The artificial lenses we use most frequently (monofocal aspheric / EDOF) can also be made toric and thus correct astigmatism at the same time.

Asférico
EDOF

Rarely used

Multifocal artificial lenses
  • Multifocal IOLs have two, three or more focal points to reduce dependence on reading glasses due to presbyopia.
  • However, experience with currently available multifocal lenses shows a loss of contrast, as well as altered color perception, which is why we rarely use them anymore.

Overall as a 50 year old, who wanted to continue to avoid wearing glasses and/or contact lenses, my goal was 100%... achieved with ELZA and Dr. Hafezi. I greatly appreciated the overall approach by Dr. Hafezi and his friendly and competent team in reviewing my vision at the start and following a comprehensive eye exam- the explanations of my options. For me I chose PRK in one eye for a monovision solution to correct short sightedness which was becoming more prevalent in night driving and sports such as skiing and cycling. PRK heals slowly but the outcome is worth the wait- and the cost- you use your eyes every waking moment- and for me I cannot see any reason not to pursue better vision with the ELZA team! A great quality of life enhancement!ler mais

I have been to the ELZA clinic to have surgery for my miopy, as my eyes were rejecting the contacts and I was tired of... wearing glasses. From the first preliminary visit, to the actual surgery and post-surgery care Dr. Hafezi and all his collaborators have been extremely professional, considerate and helpful. All the steps of the (very short!) surgery were thoroughly explained to me in order to be as calm as possible, together with the medication plan and precautions to be aware of so that my eyes could heal in the best way possible. By following their exact instructions, the healing process has been very successful and smooth, and after about one week I was able to see perfectly. I absolutely recommend this team and their expertise!ler mais

After some research on local options I decided to go with ELZA since it stood out as the best. The operation and the... post-operation recovery went extremely smooth (something I was worried about with PRK). Now my vision is much better than I had hoped and I have no side effects such as dry eye or night vision problems. Thank you!ler mais

My left eye had to be operated on because of a cataract. As I had an Artiflex lens implanted a few years ago, it had to... be removed first before a modern lens could be implanted to correct the cataract. Prof. Hafezi treated me in an very competent and friendly manner. I am very happy with the result.ler mais

At the moment, 3 months have passed since the moment I made laser vision correction in this clinic. and I can say that... I am happy that I chose this particular clinic and Prof. F. Hafezi. The entire staff of the clinic is very friendly, treats patients with sympathy and patience if they are nervous before surgery (my big gratitude to Aida Alili for all support and patience). The doctor Hafezi and other doctors of the clinic are very professional and ready to explain to you as many times as you need. I can only recommend!ler mais

The day I had Prof Hafezi checking my keratoconus I knew I was finally in the right place after years of searching for... a good ophthalmologist. Prof Hafezi recommended a surgery due to a drastic degeneration of my cornea. The surgery was performed by himself with the assistance of Dr Rodriguez, one more collaborator of Prof Hafezi’s team who got my full trust.ler mais

Professor Hafezi and the team at the ELZA Institute have done an amazing job of creating a first class eye clinic, with... cutting edge technology and support. I went there for a dry eye issue and other issues with my prescription, and they were easily able to help me and put me on the road to better vision! High recommend them to anyone in the Zurich/Aargau area.ler mais
