Corrective Eye Surgery 1
“LASIK or Lasik (Laser-Assisted In Situ Keratomileusis), commonly referred to as laser eye surgery or laser vision correction, is a type of refractive surgery for the correction of myopia, hypermetropia, and astigmatism.
The LASIK surgery is performed, using a highly specialised laser, called an excimer laser, to reshape the cornea to improve visual acuity.” more on Wikipedia and Visianinfo.
Most of us are familiar with Lasik.
A lot of us has hear about this corrective eye surgery. But out of so many of us, how many of us do actually know what is it really about?
Other then the fact that this surgery is being done, cutting and moulding the eye, with the use of laser?
Well I don’t know much about it then except that it is a wonderful surgery that can help me get rid of my dependencies on my glasses and contact lenses. and So I really really want to DO IT!
The Advantages of LASIK Eye SurgeryLASIK has many benefits, including:
- It works! It corrects vision. Around 96% of patients will have their desired vision after LASIK. An enhancement can further increase this number.
- LASIK is associated with very little pain due to the numbing drops that are used.
- Vision is corrected nearly immediately or by the day after LASIK.
- No bandages or stitches are required after LASIK.
- Adjustments can be made years after LASIK to further correct vision if vision changes while you age.
- After having LASIK, most patients have a dramatic reduction in eyeglass or contact lens dependence and many patients no longer need them at all.
With all these advantages, of course I am excited to get it done. Plus, in most cases, Standard LASIK can be completed within 10 to 20 minutes for both eyes and with results that can be seen in as little as 24 hours!
NO NEED FOR CONTACT LENS OR GLASSES AFTER!
But with every advantage comes some disadvantage. Although rare, here are some issues that we might face; as not every journey is set to be a smooth sailing one.
The Disadvantages of LASIK Eye Surgery
- Changes made to the cornea cannot be reversed after LASIK.
- LASIK is technically complex. Problems may occur when the doctor creates the flap, which can permanently affect vision
- Intraoperative risks include Cornea perforation, Flap complications, Laser hot spots, Central islands and De-centered ablation.
- Post-operative complications such as, Under-correction or over-correction, Debilitating symptoms, Dry eye, Displaced flap, Nonspecific diffuse intralamellar keratitis, Epithelial ingrowth, Striae, Photophobia and Infection.

The Potential Side Effects of LASIK Eye Surgery
The potential side effects of the LASIK surgery may include some discomfort for the patients in the first 24 to 48 hours after. Other side effects, although rare, include:
- Seeing halos around images
- Difficulty driving at night
- Fluctuating vision
- Dry eyes
See, now comes the Complicated part.
Because of all the possible complications and disadvantages Lasik could cause, various other eye surgery alternatives are available as well!
Which what most people, or I would say most Singaporeans, usually do not know about, or maybe we it is just that we categorise them all just as Lasik.
There are the PRK, Lasek, and the eli-Lasik. Yes it is a whole pile of complicated names! It all have its different advantages to curb the different disadvantages. It all depends on your eyes!
The fundamental difference in LASIK, PRK and LASEK, are on how the eye is prepared for the laser treatment.
Here are the breakdown on the Three main Procedures and its differences:
- During LASIK, a thin circular “flap” is created on the eye’s surface using a microkeratome or a femtosecond laser surgical tool. The surgeon then folds back the hinged flap to access the stroma and reshape the corneal tissue using an excimer laser.
The flap is then returned to its original position and serves as a natural bandage, keeping the eye comfortable as it heals. The flap adheres securely without stitches, and healing occurs relatively quickly.
- During PRK, instead of creating a corneal flap as in LASIK, the surgeon completely removes the extremely thin outer layer of the cornea (epithelium, which is like a clear “skin layer” covering the cornea), using an alcohol solution, a “buffing” device or a blunt surgical instrument. The underlying corneal stroma is then reshaped with an excimer laser. A new epithelial layer grows back within five days.
- The LASEK procedure involves a little of both LASIK and PRK. Like in PRK, the corneal epithelium is separated from the underlying stromal layer. But instead of completely removing and discarding the epithelial tissue, the LASEK surgeon pushes the ultra-thin epithelial “flap” to the side (it remains attached to the eye on one side, like the thicker corneal flap made in LASIK), exposing the corneal stroma for laser reshaping.
After the laser treatment is finished, the epithelial tissue is repositioned on the surface of the eye to cover the lasered stroma, and a bandage contact lens is placed on the eye to keep the epithelium in place as it heals.
So how would one know which procedures to go for?!
Yes with all the different choices we are offered, it is hard to know which is the right/suitable and better procedure for us.
Which all the more make choosing the right doctor and the right clinic more important.
As despite these eye surgeries being usually a quick and successful procedure, it is still a surgery after all. The right doctor would not only know which alternative is better for your eyes or recommend you base on your worries. Choosing the right doctor and clinic would also lessen the risk of having to deal with complications, even if it does “touch wood” happen, the doctor would be experienced enough to know how to deal with it!
Thus, when finding the clinic, it is still good to stick to the more experience ones! After all it is still our eyes we are Talking about!! :O It was with this mind set which land me up in the EyeDream Eye Clinic 아이드림안과 in Seoul, Korea.
