Monovision is used for the treatment of presbyopia. Each eye is thereby subjected to different optical power corrections, to prepare one eye for long-sightedness and the other for short-sightedness. So, in other words, one short-sighted and one far-sighted eye is artificially produced.
The dominant eye is corrected for far distances, and the other for things that are near. There are patients who cope well with this method, and others feel uncomfortable. Our job is to figure out your preferences even before the surgery by using simulated spectacles or contact lenses. Ultimately, you decide, depending on your professional and personal requirements, whether monovision is an option for you.
This monovision can be done in different ways: with the help of contact lenses, by an eye laser treatment or by the implantation of intraocular lenses. Usually people between the ages of 35 and 65 are suitable for monovision – mainly for those who are short-sighted and where presbyopia has already begun.
In the best case scenario, monovision will allow considerable independence from spectacles or reading glasses. An average result is, at least, the decline of defective sight, which may be accompanied by a reduction in the dioptres of one’s reading glasses.
Contact lenses, which are individually adapted to your needs, simulate the possible outcome of the treatment over one to two weeks. This allows you to already judge in advance whether monovision is an option for you.
In monovision you undergo LASIK surgery or implantation of Phakic lenses. Your dominant eye is corrected for distance in both methods, and your non-dominant eye for near vision.
A separation of the functions of both eyes is usually well accepted – if both eyes work together perfectly, the result for the brain becomes a highly visible picture. Depth perception may be affected, this is, however, not a disadvantage for most activities. Depending on your needs and personal preferences, you will already recognize in the preliminary examination or during contact lens simulation, whether this method is suitable for you.
After treatment the brain definitely needs time to get used to the new conditions. If you are not satisfied with the result after the treatment, both eyes can be adjusted to far distances afterwards. You would need to continue using reading glasses for short distances. We would be happy to clarify any other risks for you here.
