Eye & LASIK Profile Image

Eye & 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.

Read this post for more information on LASIK treatment in Singapore.

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.

Immediately after LASIK, vision is generally misty and the eyes sometimes may feel a bit teary or irritated. These symptoms get better very fast, so that by the next day vision is much better and most of the mistiness is gone. Usually the discomfort is also gone by then, although the eyes can feel ...

Any laser refractive surgery, whether LASIK, PRK or SMILE changes the corneal shape. Sometimes more, and sometimes less, depending on the amount of spectacle power that is to be corrected. There are a number of different types of contact lenses, but basically you can differentiate them into soft ve...

The risks of customised femto-LASIK surgery are essentially the same as for any other LASIK surgery. Although it is not possible to list every single possible side effect or complication, in counselling patients for surgery we usually explain conditions that happen relatively common...

Hi there! The treatment options for glaucoma can be broadly divided into 3 categories -- medications, lasers, and surgeries . All these treatment options have the common aim of lowering eye pressures so that the optic nerve does not continue to be damaged, and vision can be pre...

First of all, you need to imagine our eyes working like a camera, all parts of the camera from the external aperture and shutter to the internal lenses and film have to all be well-functioned to give you a clear image. It is akin to our eyes from the cornea all the way to the lens a...

With high myopia, we must first ascertain if you have sufficient corneal thickness for you to safely undergo laser vision correction. The higher the myopia, the more corneal tissue needs to be removed. Hence, having sufficiently thick corneas is an important consideration. A compreh...

Refractive surgery is usually recommended when your refractive error has stabilised, and that usually occurs between 18 - 21 years of age. If you are significantly older than that, or your refractive error has worsened significantly then a comprehensive evaluation by your ophthal...

Hi, whether you will get a good result from LASIK surgery depends on many things, such as the result from your previous strabismus surgery, the type of strabismus, your best possible vision and the presence or absence of amblyopia/lazy eye, and how high your astigmatism is. You m...

Shortsightedness after cataract surgery can be treated in the same ways as for people who have not had cataract surgery. That is, you could wear spectacles, contact lenses, or consider having laser refractive surgery depending on your individual preferences and activities. Gen...
