Why cataract surgery?

When contours lose their sharpness, and colors begin to fade, an advancing cataract is often the underlying cause. A cataract is an entirely natural companion of aging.

The positive news: Cataracts can be completely resolved through a quick outpatient procedure. Moreover, if you have a refractive error such as nearsightedness or farsightedness, it can be corrected during the surgery by inserting a premium lens.

With Ziemer's Modern Laser Cataract Surgery (Z-Cataract) this procedure is much more precise and with a consistency far superior to what is possible with manual techniques. 

How does the surgery proceed exactly?

The surgery involves removing the clouded lens (cataract) and inserting an artificial lens:

  1. At the beginning small incisions are made at the edge of the cornea with our Ziemer Z8 Femtosecond laser.
  2. It then creates a circular opening in the front part of the lens capsule, allowing access to the clouded lens.
  3. Afterward, the laser fragments the clouded lens, breaking it into small pieces for easier removal.
  4. Finally, the artificial lens is implanted to restore your vision.

Pre-operative examination

The pre-operative examination is a comprehensive process where the patient's eyes undergo meticulous measurements, providing crucial data for the impending cataract surgery. Beyond assessing potential surgical risks, this examination delves into a detailed discussion about the available artificial lens options. Patients receive comprehensive information on the advantages and disadvantages of both standard and premium lenses, empowering them to make informed decisions tailored to their individual needs and expectations for optimal post-operative outcomes.

Follow-up examination

The first follow-up is typically scheduled for the day after the operation, playing a pivotal role in assessing the success of the treatment. This meticulous follow-up examination is essential in monitoring the post-operative progress, addressing any immediate concerns, and ensuring the patient's eye health and recovery. You can expect to notice a significant improvement in your vision immediately after cataract surgery.

What are the advantages of cataract surgery?

Cataract surgery using the femtosecond laser is practically pain-free, utilizing the latest, extensively proven technology, and offers a high potential for achieving outstanding postoperative vision.

 

The capsulotomy (circular opening of the front lens capsule) performed with the femtosecond laser is significantly more precise than the previously practiced manual approach. An optimal capsulotomy is essential for the good and stable positioning of the intraocular lens. This aspect becomes particularly crucial if you have opted for a premium lens such as a multifocal IOL or a toric IOL.

The lens fragmentation of the cloudy lens with the femtosecond laser is safe and gentle. The laser can create highly precise minimal incisions, eliminating the need for sutures. This makes the treatment exceptionally safe and gentle when compared with other methods.

 

The healing process and visual improvement after cataract surgery performed with a femtosecond laser are remarkably fast. You can expect to resume most of your regular activities within just a few days after the surgery.

The intraocular lens (IOL) implanted during a femto-cataract operation allows for very good vision immediately after the procedure. It can be customized to not only address cataracts but also correct a pre-existing refractive error.

The complication rates following a modern cataract operation are historically low. However, it is still advisable to have regular eye check-ups and to promptly consult an eye care professional if unexpected symptoms occur.

Questions? Answers.

When to have cataract surgery depends primarily on its effects. Lens opacity alone is not a sufficient reason for cataract surgery. It only becomes necessary when cataracts start causing issues in your daily life. Therefore, it's advisable to have regular eye examinations. During these appointments, you can discuss with your eye care professional to determine the appropriate time to undergo cataract surgery.

The surgery itself takes approximately 15 minutes. Including preparation and postoperative care, you can expect about 2 hours in total. Commonly, patients opt to have surgery on both eyes within a period of one to two weeks.

From the first day after the operation, you can usually resume all of your usual activities, including sports.

Cataract surgery is one of the most commonly performed procedures in medicine. The procedure is considered very safe, with the vast majority of surgeries proceeding without complications. However, in rare cases, issues can arise during and after the operation.
