Treatment may include spectacles, contact lenses, refractive surgery or intraocular lens implantation.
Spectacles are the simplest way of solving the problem, especially if there are no other refractive defects. If there are, the glasses must contain both distance and near refraction, which will require the use of bifocals or multifocals (progressive).
Contact lenses, if there are no contraindications to their use, are another solution. In myopia patients, who are generally more accustomed to using them, monovision is often used. In this case the patient wears a lens for distance in the dominant eye and another for near in the other eye. There are also multifocal contact lenses. Not all patients adapt to these because of the accessory images they cause with the lights at night and the frequent feeling of blurred vision.
Laser refractive surgery, LASIK, LASEK or PRKLASIK , LASEK or PRK, also has the possibility of achieving near vision correction. This is also a monovision technique. With correction of presbyopia in the non-dominant eye and distance correction only in the dominant eye. It is effective, above all, for myopiaIt is effective, especially in myopia, in resolving the difficulty. However, since presbyopia is progressive, it will be necessary to repeat the procedure on the non-dominant eye some years later.
Intraocular lens implantation surgery is very effective and definitive. It involves the removal of the clear crystalline lens with the implantation of a multifocal, bilateral lens. presbyopia (there is no longer a crystalline lens so that the presbyopia At the same time, the patient is able to correct other refractive defects, such as astigmatism, hypermetropia or myopia. The intraocular lens is calculated to correct all existing defects through biometry. Using both eyes for distance and near also improves the quality of vision.
In low light conditions it is sometimes difficult to read and in some cases the occasional use of simple, low prescription glasses is still necessary. It is also necessary to consider, in some cases, the possibility of glare at night and of seeing halos in the lights. Apart from these symptoms, the surgical risk must also be taken into account.
