LASIK Profile Image

LASIK

LASIK is eye surgery that corrects nearsightedness by using a laser to reshape the eye's cornea, while cataract surgery replaces a cloudy lens from your eye with an artificial lens to restore clear vision.

LASIK overview

LASIK is a type of refractive surgery for the correction of myopia, hyperopia, and astigmatism.

The LASIK surgery is performed by an ophthalmologist who uses a laser or microkeratome to reshape the eye's cornea in order to improve visual acuity.

For most people, LASIK provides a long-lasting alternative to eyeglasses or contact lenses.

Cataract surgery overview

Cataract surgery is the removal of the natural lens of the eye that has developed an opacification, which is referred to as a cataract.

Many peoples' first symptoms are strong glare from lights and small light sources at night, along with reduced acuity at low light levels.

During cataract surgery, a patient's cloudy natural cataract lens is removed and replaced with a synthetic lens to restore the lens's transparency. Following surgical removal of the natural lens, an artificial intraocular lens (IOL) implant is inserted.

Well over 90% of operations are successful in restoring useful vision, with a low complication rate. 

Risks of LASIK 

  • Dry eyes - A reduction in tear production is possible for the first few months after the LASIK surgery. Eye drops can be a temporary solution to this 

  • Under-correction - It is possible that too little tissue is removed from your eye, causing you to still not have perfect vision. Another procedure will be needed if this is the case. 

  • Over-correction - The opposite to the condition above, though this will be slightly more cumbersome to fix. 

  • Vision Loss - On the most extreme and rare spectrum, vision loss could occur due to some mishap or may not be able to see as clearly as before. 

How long it takes to recover from LASIK surgery 

Theoretically, you should be able to see better after 1 day of your surgery. Nevertheless, it is common for your vision to be slightly blurry or unclear for the first few weeks as your eyes are adjusting. A good guideline would be that the higher your inital prescription, the longer it will take to recover from the LASIK surgery.

With any refractive surgery, whether SMILE, LASIK, PRK or ICL surgery, there is a chance of over-correction or under-correction . So if a person was myopic before surgery, an 'overcorrection' would cause hyperopia, and vice versa. Usually, the degree of under or over-correc...

Getting ReLEx SMILE in Singapore: An Insightful Guide by an Eye Doctor (2019)

Getting ReLEx SMILE in Singapore: An Insightful Guide by an Eye Doctor (2019)

ReLEx SMILE is a laser eye surgery to treat myopia and astigmatism. It is a minimally invasive procedure that aims to help you gain independence from glasses and contact lenses.

I am sure that you have heard about similar procedures such as LASIK and Advanced Surface Ablation (ASA). There are also different types of ASA such as PRK, epi-LASIK, LASEK, and TransPRK. All these methods exist to treat different eye conditions. That said, your suitability also depends on the shape and anatomy of your eye.

Blurry vision can be a problem that affects your quality of life and performance at work or in school. Although most people wear glasses and contact lenses to address that, they can still be an inconvenience.

In this article, I will discuss how ReLEx SMILE can be a suitable option for you, explain its treatment process and compare it with other treatments.

In general, soft contact lenses are a lot more comfortable than rigid gas permeable (RGP) contact lenses. They are also much easier to fit, and can give very good vision. Both soft and RGP lenses may be suitable for many people. But each has their potential pros and cons . ...
