Surgical correction of presbyopia
Presbyopia is a disorder of vision, where the eye has more and more difficulty focusing up close.
This disorder is not a disease but a normal aging phenomenon of the eye. This symptom appears most commonly between the ages of 40 and 45, and changes up to about 65 years.
The challenge is to find a compromise that allows the patient to function as much as possible without reading glasses, while maintaining good visual quality from a distance.
Monovision consists in correcting one eye for distance vision and the other for near vision.
It can be practiced with LASIK technology or with intraocular implants.
• Patients are functional in their daily activities 90% of the time without glasses or contact lenses.
• The two eyes do not see equally, so the vision in 3 dimensions is reduced. This can be a disadvantage for practicing certain sports.
The only way to check your ability to tolerate this imbalance is to try this combination in contact lenses.
MULTI-FOCAL CORNEA (E.G. ‘LASER BLENDED VISION’, ‘PRESBYVISION’, ETC..)
This technique, performed by an excimer laser, is a variant of monovision. A multifocal cornea is created in each eye to increase the depth of focus of the eye.
• This multi-focality reduces the quality of vision. That's why at Laservue we do not yet favor this technique, even though it is available to us.
CORNEAL IMPLANTS (KAMRA AND OTHERS)
corneal implants (kamra and others)
These implants, inserted into the cornea, are intended to improve near vision. The KAMRA implant increases the depth of field by reducing the diameter of the pupil.
Laservue was the first clinic in North America to perform these surgeries in 2012, but has not been practicing it for a few years. Doctors Mullie and Balazsi are waiting for an advance of this technology, in order to be able to propose a better visual solution without the known disadvantages.
INTRA-OCULAR LENS IMPLANTS
Multifocal intraocular lenses can replace the lens to correct vision at several distances
