Monovision is used in treating presbyopia. Each eye is subjected to a different correction for the strength of the refraction of light for the purpose of preparing one eye for distance vision and the second eye for near vision. In short, an artificial step is made to create one nearsighted eye and one farsighted eye!

The eye will self-guide to distance and the second up-close. The patient’s preference is recognized before the operation, with the help of simulation with glasses or contact lenses. Finally, depending upon their vocation and personal feelings, the patient can decide if monovision is the best solution for him.

Monovision can be performed in several ways: contact lenses, through optical laser treatments or inner intraocular lens implants. Monovision is most often performed between the ages of 35 and 65.

In the ideal situation, the outcome of monovision is a high degree of independence from glasses or reading glasses. A secondary outcome is the lessening of the vision weakness, which means a lesser number of diopters in helping with reading.

Operation procedure

Prior to the procedure, a test is done with contact lenses matched to the needs of the patient as a simulation of the results of the proposed procedure. The trial lasts for one to two weeks and upon the assessment, it will be decided if monovision is the best option for the specific patient.

In the case of the monovision procedure, the patient is subjected to the operation with the Femto-LASIK method, Phakic lens implant or lens replacement. All of the methods correct the dominant eye to see distance and the second eye to see near.

Important information

Dividing the functions of the eye is usually well received – eyes perfectly work together, and the general picture is clarified by the brain. Although certain vision effects will arise, they are not harmful for most of the actions performed. Depending upon the desires and preferences of the patient, during the initial examination or lens simulation, the patient is able to express whether this method is suitable for him.

In each case, the brain needs time to adjust to the new conditions. If the result of the procedure is not completely satisfactory, the eyes can later be adjusted for distance vision. Then glasses can be worn for near vision and reading.
