Presbyopia is a gradual lose of focusing ability of the lens on near objects. Because of some changes in our eye muscles, the shape of the lens is also affected. Presbyopia starts at the mid 40’s and finally affects everyone.

The main problem is very similar to hypermetropia. Focal point of light rays coming from near objects remains behind the retina and out of focus. In Hypermetropia, eyeball is shorter than a normal one. But In Presbyopia, that aged lens become harder and less flexible. This change causes difficulty in accurate refraction of the light rays to focus in front of the retina.

Reading may be more difficult at night or in dim light when you are tired. Presbyopia occurs regardless of your refractive disorder.

The first symptom of Presbyopia is feeling necessity to keep the near objects away from you while you are reading. As the time passes blurry vision increases and pain occurs at forehead and temple. Focusing the eye on near objects by force cause other problems. After reading, clear vision for distant objects might temporarily be difficult due to the ability of focusing. The only solution of Presbyopia is optical correction (reading glasses or contact lenses). For myopia, people using corrective lenses may need bifocal glasses (upper part is used for distant vision and the bottom part is for near vision) or they use two separate glasses for different distances.

Because Presbyopia progress until the age of 60’s prescriptions change frequently. After 60’s, presbyopia becomes more stable. From the age of 60-65 focusing ability of the eye actually stops since the lens has lost its flexibility; at this level near vision is completely dependent to the glasses. However Myopia people sometimes take off their distant glasses for near vision and they can do their activities more comfortably.

The symptoms of Presbyopıa

Patients with presbyopia find difficult to see the objects near than 50 cm. For this reason they can have a bettter vision by moving the objects away. As time passes if the patient has poor near vision, they also may have some pain in the forehead and temple.


There are many kind of treatment methods in the world. These treatment methods have their own advantages and disadvantages. Today we treat presbyopia in our hospital either multifocal lens implementation or presbylasik laser which has been known as the most reliable method in the whole world for the Presbyopia.

1. Treatment wıth Glasses

  • Bifocal Glasses
  • Multifocal (progressive) glasses

2. Treatment wıth Contact lenses

Multifocal contact lenses: Patients who are found suitable for lens use,. However patients over 40 years of age may face some difficulties in use due to the poor tear quality. Monovision with contact lens (leaving one eye myopia): Adaptability to the treatment becomes certain only after the first examination.

3. Surgıcal treatment

There are 2 different places for this treatment

a. Cornea

  • Presbylasik Treatment
  • Monovision excimer laser treatment

b. Lens

  • Multfocal Lenses
  • Accommodative Lenses
