Laser Treatments

Presbyopia is the progressive loss of the ability to focus near that occurs naturally from the age of 40-45 years.
It can be corrected in its early stages by laser treatment, especially for myopic individuals, treating the dominant eye for distance and leaving mild myopia in the second eye so as to facilitate PC work and etture. This strategy is called mini-monovision or combined vision.

Refractive lensectomy with trifocal lens implantation

In cases of hypermetropia or high myopia and in individuals close to 50 years of age, the solution to presbyopia is surgical and involves removal of the lens, even if transparent, with implantation of multifocal intraocular lenses. Often the lens of choice is the trifocal lens: this lens has a distance focus, one for the intermediate distance between 60 and 80 cm, depending on the model, and the third focus for reading, typically at about 40 cm. The intermediate focus is extremely useful for PC work, for being able to see the car’s dashboard and navigation system sharply, or for performing mid-range work such as reading a score.

It involves performing cataract surgery without there actually still being opacification of the lens, and for that reason it is called Refractive Lensectomy. The surgery can correct the basic refractive defect and provide excellent near vision.

Not all people are suitable for this type of surgery. The ideal person is positive, eager to move away from glasses and tolerant of the possible visual disturbances that such lenses may induce in the evening. This is the possible sight of faint halos or rays around point light sources in the evening. As a rule, there is neuroadaptation within a few months that cancels these phenomena.
