Presbyopia: causes and symptoms

Presbyopia is a condition for which the eye cannot focus near objects after the patient is 40 years old

It is a vision defect that depends of the lens loosing its accomodation power. The lens can in fact change its shape to better focus objects located at different distances. As people age, the lens starts loosing this ability and people suffering from presbyopia have difficulties when trying to focus on near objects.

A lens with progressive geometry of multifocal can guarantee a good vision quality at all distances. The different segments for correction blend one into the other, offering a comfortable passage from far to near objects.

Different from bifocal (or trifocal) lenses, progressive lenses don’t have the characteristic border destined to near sight; anyway they can cause problems in terms of adaptations during the first period of time. It may also happen the patients cannot tolerate them.

Presbyopia is an ever evolving process. Around 65 years of age, people reach the final phase. Routine screening can be performed by your ophthtalmologist. In any case, everyone should be regularly checked by the ophthalmologist to spot problems early on.

It is possible to cure presbyopia for good using: excimer laser, femtosecond laser, intraocular lenses and intraocular contact lenses. The latest news is the High Tech intraocular lens that can be customized with laser. This presbyopia surgery has been performed in Milan for the first time by Dr. Badalà in 2010. He’s the author of a chapter of the book Mastering Refractive IOL’s, related to this subject.

Presbyopia laser surgery

Correcting presbyopia with laser consists in changing the corneal curvature with the excimer laser that vaporizes corneal tissue, changing corneal shape and power. Presbyopia laser surgery is about creating a multifocal that makes it possible to see well both near and far objects; this is performed with several surgical techniques.

Main techniques are LASIK and PRK. Today there are several variations of these two techniques, for example: LASEK and Epi-LASIK, that come from the original PRK technique, while Femto LASIK o iLASIK is the more modern version of LASIK, where a laser does what was usually performed with a microkeratome.

Laser surgery can be performed with several techniques. Dr. Badalà perform myopia laser surgery in Milan and Catania with latest generation excimer lasers such as:

  • VISX Star 4 (AMO)
  • Technolas 217p (Baush & Lomb)
  • Wavelight Allegretto (ALCON).

It is very important to rely on a modern laser to cure the eyes. The same attention should be put in choosing among the different laser tools, because everyone has its own strong points.

Presbyopia surgery with AcuFocus (KAMRA inlay)

This is an innovative method to cure presbyopia through the implant of a lens inside the cornea.

This lens called AcuFocus, correct presbyopia because it focuses on images of near objects on the retina. Usually, only one eye is treated: this is why the whole surgery costs is less than standard presbyopia surgery where both eyes are treated.


Antonio Parrino, Milan

Votazione: Eccellente
Problem: Astigmatism, Presbyopia
Solution: PRK
I underwent PRK for hypermetropia, astigmatism and presbyopia in January 2014.

About ten years ago I underwent PRK to correct myopia. Over the years my sight has gotten  worse, then I met Dr. Badala, who proposed me ... Keep on reading this reviewa customized PRK.

6 months after surgery the result is very good: I got back my eyesight without glasses.

The only advice I can give to those who approach this surgery for the first time is to keep the eye still during laser treatment. During the operation you do not feel any pain. Two/three days after day I felt a little but bearable discomfort.

It is very important to carefully follow the doctor's instructions such as: the use of eye drops and sunglasses, rest, do not touch the eye and avoid injuries...for the first few days it takes a little patience, but in the following weeks the result is appreciated day after day.
