Presbyopia
Alteration in focusing ability with aging
What exactly is presbyopia?
Presbyopia affects a large portion of the population and is often the reason someone may need glasses for the first time in his / her life. Over the years, the natural crystalline lens of the eye, loses its elasticity, resulting in a diminished ability to focus on close objects. Presbyopia is a dynamically evolving condition rather than a static one.
What are the symptoms of presbyopia?
The first symptoms of presbyopia typically appear after the age of 40, presenting differently in each individual, and often include:
The tendency to hold reading material at arm’s length
Blurred vision (reduced focus) at close and intermediate distances
Eye strain after daily activities, such as reading, driving, and working on a computer or tablet
Headaches or migraines
What are the causes of presbyopia?
The primary cause of presbyopia is that the crystalline lens of the eye becomes stiffer (rigid) with aging, making it less able to change shape easily and thus less effective in adjusting focus for near vision.
What are the treatment options for presbyopia?
Presbyopia can be managed using one of the following methods:
Presbyopic (multifocal) vision glasses
Contact lenses (multifocal)
Laser refractive procedure (Monovision or Presby – LASIK techniques)
Surgical implantation of a multifocal intraocular lens (IOL), often combined with cataract surgery
Presbyopia is undoubtedly a complex condition and requires an analytical assessment by an ophthalmologist to determine the most appropriate treatment solution. Not all presbyopic individuals are suitable candidates for all treatment methods.

Laser Surgery
Get rid of glasses and contact lenses for good. Laser refractive procedures are the most popular surgical procedures for correcting common refractive errors (myopia, hyperopia, astigmatism), offering excellent post-operative results.
