What Is LASIK? Myopia, Hyperopia, Astigmatism & Glasses Removal Explained

Are you tired of wearing glasses or contact lenses every day? Have you heard about LASIK but aren't sure what it is or whether it's right for you?

In this video, we'll explain what LASIK surgery is, which vision problems it can correct, and whether it can permanently reduce your dependence on glasses.

What Is LASIK?

LASIK stands for Laser-Assisted In Situ Keratomileusis. It is an advanced laser vision correction procedure that reshapes the cornea—the clear front surface of your eye—so that light focuses correctly on the retina.

When light is focused properly, you can see clearly without relying on glasses or contact lenses. LASIK is a quick, minimally invasive procedure with fast recovery for eligible patients.

Which Vision Problems Can LASIK Treat?

LASIK is commonly used to correct three major refractive errors:

1. Myopia (Nearsightedness)

In myopia, nearby objects appear clear, but distant objects look blurry because light focuses in front of the retina.

LASIK reshapes the cornea so that light focuses directly on the retina, improving distance vision.

2. Hyperopia (Farsightedness)

In hyperopia, distant vision may be clear, but nearby objects appear blurry because light focuses behind the retina.

LASIK changes the shape of the cornea to bring the focus onto the retina, improving both near and distance vision in suitable candidates.

3. Astigmatism

Astigmatism occurs when the cornea has an irregular shape, causing blurred or distorted vision at all distances.

LASIK smooths and reshapes the cornea to improve the way light enters the eye and enhances visual clarity.

Can LASIK Remove Glasses Permanently?

For most eligible patients, LASIK significantly reduces or eliminates the need for glasses or contact lenses by permanently reshaping the cornea.

However, LASIK does not stop the natural ageing process of the eye. As you get older, conditions such as presbyopia (age-related need for reading glasses) or cataracts may still develop. This does not mean the LASIK treatment has failed.

Who Is Eligible for LASIK?

You may be a suitable candidate if you:

• Are 18 years or older
• Have had a stable glasses prescription for at least one year
• Have healthy corneas with adequate thickness
• Have no active eye infection or severe dry eye
• Pass a comprehensive pre-LASIK evaluation

Eligibility is always confirmed after detailed eye tests performed by an ophthalmologist.

Is LASIK Safe?

Yes.

LASIK is one of the most commonly performed laser vision correction procedures worldwide. When performed on carefully selected patients using advanced technology by experienced ophthalmologists, it has an excellent safety profile and high patient satisfaction. Proper screening is the key to successful outcomes.

Benefits of LASIK

Patients often choose LASIK because it offers:

• Reduced dependence on glasses or contact lenses
• Quick and minimally invasive treatment
• Fast visual recovery
• Greater convenience for work, sports, and travel
• Long-lasting vision correction for eligible patients
