What Is Presbyopia?
Presbyopia is the gradual decline of your eyes’ ability to focus on near objects, causing objects to become blurry for near vision.
Most people experience presbyopia in their late 30s to early 40s. If you’ve noticed that you have to hold a book farther away to read that you used to, you probably have presbyopia.
“Presbyopia or lao hua is a natural part of ageing. As we cannot reverse ageing, there is no perfect solution for presbyopia. Thus, it is important to know that all treatment methods for presbyopia are compromises.” – Dr. Tony Ho, Clearvision Eye Clinic & LASIK Centre.
“I have lao hua only”
The eye surgeon will usually only correct one eye (the less dominant eye), creating a multifocal cornea in that eye with laser vision correction. This eye will be able to see better for near vision.
“I have both myopia and lao hua”
The eye surgeon will correct both eyes with laser vision correction. One Eye will be corrected to see clearly in the distance (your dominant eye), and the other eye (your non-dominant eye) to see better for your near vision activities.
Correcting Presbyopia – The process
1. The pre-LASIK Evaluation
You will have to undergo a pre-LASIK evaluation which comprises a series of eye tests, checking your eye power, cornea thickness and general eye health. You will find out if you are suitable for presbyopia correction here.
2. The Trial Lens Test
To allow you to experience and adapt to Monovision or PresbyMAX, the eye doctor will provide you with trial contact lenses to be worn in one of both eyes. You will wear these trial lens for about 1-2 weeks.
3. The Laster Treatment
Usually after 1 – 2 weeks, the brain begins to seamlessly use the eyes in a monovision manner. When you are comfortable with your monovision trial lens experience, you can then proceed with laser treatment to permanently correct your vision.
