Presbyopia Guide

What is Presbyopia (a.k.a “lao hua yan”)?
Presbyopia (a.k.a. “lao hua yan”) is a refractive error in the eye, which causes difficulty in focusing on objects up close. Presbyopia affects everyone and is part of the natural aging process. Most people start experiencing presbyopia as early as mid forties when they begin to experience difficulty focusing on near objects.

Presbyopia can be detected through a standardized eye examination. These tests include examination of the retina, muscle integrity test, refraction test, slit-lamp test and visual acuity.

There is no cure for presbyopia, however patients suffering from this eye disorder can be treated with corrective eyeglasses or contact lenses, by adding bifocals to an existing lens prescription. The strength of bifocals is increased as the ability to focus worsens.

Presbyopia can cause complications to other common vision conditions such as nearsightedness, farsightedness and astigmatism. Therefore due to the changes in the ability of the crystalline lens to focus properly, it may be necessary to go for regular eye test to detect changes and maintain a clear and comfortable vision.

Causes of Presbyopia
As the elasticity of the crystalline lenses start to decrease, the ability of the lens to change it’s shape is also reduced. This decreases the ability of the eye to focus on nearby objects, causing presbyopia.

Symptoms of Presbyopia
Common symptoms of presbyopia include decreased ability to focus on nearby objects, eyestrain, and frequent headaches.

Treating Presbyopia with LASIK
Presbyopia can be corrected using LASIK, a type of refractive surgery that uses laser to reshape the cornea. To learn more about LASIK, contact ClearVision using the enquiry form below:
