There are different types of lenses, which may be applied by the surgeon considering the patients needs and wants. While the focus areas of the lenses increase, the prices of the lenses increase exponentially, increasing the price of the operation accordingly.
Monofocal Lenses – the most used lenses that work well for correcting vision at one distance and glasses will still be necessary to use. The monofocal lenses don’t correct astigmatism as well.
Multifocal Lenses – it did not take long to realize that monofocal lenses did not meet all the needs so multifocal lenses were invented starting with bifocal lenses. Multifocal lenses are mostly suitable for people over the age of 40 and who are affected by presbyopia.
There are different types of multifocal lenses. These type of lenses help improving the distant and near visions. As the improvements in all areas of the world continue, the need for a better multifocal lens emerged. Especially while looking at mid-distances, like looking at a computer, bifocal lenses did not meet the needs. Therefore, trifocal lenses were invented where it was aimed to permanently free patients from using glasses. These lenses help improving the vision at all distances – near, intermediate and far. The multifocal lenses are the closest ones to give a perfect vision in both eyes.
Toric Contact Lenses – specially designed lenses that correct astigmatism and differ from normal contact lenses because of its shape and its different power to correct astigmatism.
