Who is a Candidate for LASIK?

 
Contrary to popular belief, not everyone is a good candidate for laser surgery, and your ophthalmologist will perform a pre-test to ensure that you meet the basic criteria. To be a candidate for a custom LASIK procedure, you must meet the following requirements:
 
  • Be over 18 and in good general health. 
  • Have stable vision for at least a year. 
  • Is bothered by wearing glasses or contact lenses at work and in daily activities. Patient is not be pregnant or nursing and is not be suffering from other corneal or ocular diseases such as age-related macular degeneration, severe dry eyes, or an illness that could affect wound healing such as lupus. 
  • Have a thorough understanding of the procedure, and realistic expectations.

 


Minimal Complications

 
Refractive surgery is a life-changing decision that must always be made after being informed of the risks as well as the benefits. Overall, LASIK is a safe and effective vision correction procedure when performed by an experienced ophthalmologist, and serious complications that result in the need for surgical intervention or cause significant vision loss are very rare. Minor problems include:
 
  • Infection 
  • Under- or over-correction 
  • Reduced low-light vision, sensitivity to light, and visual distortion such as glare, haloes or starbursts around light sources that may be bothersome or make driving at night difficult 
  • Initial fluctuations of vision 
  • Dry eye syndrome



LASIK Procedures

 

a) ReLEx (Refractive Lenticule Extraction) smile
 
ReLex is the latest technique in eye treatment that takes laser vision correction for short-sightedness beyond LASIK.  It uses the femtosecond laser to precisely separate and then remove a ‘lenticule’ (tiny disc) of tissue to re-shape cornea and change its lens power. Similar to LASIK, the corneal surface layer is largely untouched as such the procedures share the same benefit of minimal post-operative discomfort and rapid visual recovery. Because no excimer treatment is necessary, the laser procedure itself is quicker and there is no ablation.
 
  • ReLEx :SMILE (Small Incision Lenticule Extraction)

ReLex SMILE in particular offers significant benefits: using the Femtosecond laser the corneal surface incision (2-5mm) is much smaller, and there is no ‘flap’ so the approximately 20mm cut of LASIK is reduced by more than three-quarters. This method has minimal side effects and is highly accurate. 
 


Advantages of ReLEx

 
  • No pain during procedure
  • No chance of the flap moving, shifting, dislocating or folding
  • A Minimally Invasive Refractive Surgery (increased safety and reduce complications)
  • ReLEx has high accuracy and can be customized according to each patient’s needs   
  • Much better for the long term stability of the cornea
  • Much less chance of developing dry eyes

b) FemtoLASIK 
 
The advanced bladeless FemtoLASIK (All-Laser LASIK) used by the surgeons at Bangkok Hospital LASIK Center utilizes the latest generation of specialized ultrafast, femtosecond lasers, which were designed for the creation of corneal flaps during the LASIK procedure. This newest version of the VisuMax femtosecond laser machine from Carl Zeiss creates a corneal flap with a precisely predetermined pattern and depth that were once considered unattainable for people with corneas too thin, flat, steep or irregular in shape.
 
Combined with Carl Zeiss Meditec MEL 80 excimer laser, which is designed to make the correction of vision defects even safer and more patient-friendly, FemtoLASIK technology delivers a fast, safe and comfortable LASIK procedure while reducing the amount of thermal energy delivered to the cornea with excellent treatment results.
 
This highly accurate technology also results in significantly fewer overall LASIK complications such as dry-eye syndrome, or perception of halos around lights at night, and much faster recovery. It is a same-day procedure and patients return home immediately afterwards. 
 

c) Laser Blended Vision (LBV) 
 
When we age, the lenses inside our eyes begin to lose the ability to change shape that is required to focus on near and far objects, a condition called presbyopia. Thanks to the Zeiss MEL-80TM Laser, we can now compensate for the symptoms of presbyopia with Laser Blended Vision, which enables doctors to restore 'multiple-focus' ability, correcting long- and short-sightedness and enhancing reading vision.
 
The Laser Blended Vision Treatment adjusts each eye in different ways, offering patients freedom from bifocal reading glasses and contact lenses.  
 

d) LASIK
 
After 30 years of research and development the Excimer Laser was found to have special properties and can be used in correcting eye related impairments. LASIK or Laser-assisted In-Situ Keratomileusis is a type of refractive surgery using a laser or microkeratome to reshape the eye’s cornea in order to improve vision acuity. 
 
First, your eye surgeon uses a microkeratome or a femtosecond laser to create a thin, circular flap in the cornea. The hinged flap is then folded back to gain access to the underlying cornea, corneal tissue is then removed using an Excimer Laser. This highly specialized laser uses a cool UV light beam to remove microscopic amounts of tissue from the cornea to reshape it so it more accurately focuses light on the retina for improved vision. 
 
For nearsighted people, the goal is to flatten the cornea; with farsighted people, a steeper cornea is desired. After the laser reshapes the cornea, the flap is then laid back in place, covering the area where the corneal tissue was removed. Then the cornea is allowed to heal naturally. Laser eye surgery requires only topical anesthetic drops, and no bandages or stitches are required. Patients will be able to recover sooner and be able to return to work the very next day.
 

e) PRK
 
PRK (photorefractive keratectomy), also known as 'surface ablation', was the first type of laser eye surgery for vision correction. Like LASIK and other types of laser eye surgery, PRK works by reshaping the cornea by removing microscopic amounts of tissue from the corneal stroma using a computer-controlled beam of light (an excimer laser). The main difference from LASIK is that the top layer of cells that cover the surface of the cornea is removed and a bandage contact lens applied so no flap is created.
 
The primary advantages of LASIK over PRK is that there is little or no discomfort or pain immediately following the procedure, and vision returns more rapidly, usually within hours rather than days.
 

f) Phakic IOLs: An alternative to Lasik and PRk
 
Phakic IOLs (intraocular lenses) are an alternative to LASIK and PRK eye surgery for correcting moderate to severe myopia (nearsightedness), and in some cases produce better and more predictable vision outcomes than laser refractive surgery.
 
Phakic IOLs are clear implantable lenses that are surgically placed either between the cornea and the iris (the colored portion of your eye) or just behind the iris, without removing your natural lens. Phakic lenses enable light to focus properly on the retina for clearer vision without corrective eyewear. Implantable lenses function like contact lenses to correct nearsightedness. The difference is that phakic IOLs work from within your eye instead of sitting on the surface of your eye
 
The Phakic IOLs surgery procedure is considered low risk. The patient will receive anesthesia to reduce any uncomfortability that may occur during the surgery which will last approximately 30 minutes, after which the patient is free to return home.
 
The Phakic Intraocular Lens or Phakic IOL that we provide for patients are Implantable Collamer Lens (Vision ICL) from STAAR Surgical, a world renowned leader in medical technology that receives US FDA Approval. Vision ICL has also received the CE mark from Europe, and today is used in over 41 countries worldwide. The results of ICL implants show great accuracy and are effective for patients who may be unfit to undergo LASIK. 
 


Before the Procedure

 
  • You will need to undergo an extensive pre-operative eye examination and investigation by your ophthalmologist.( This may take 2-3 hours)
  • Refrain from wearing contact lenses for a period of time specified ( at least 3 days for soft contact lens and 7 days for semi-hard or hard contact lens).
  • Arrange for transportation, or let the coordinators at the center assist you - it is not advisable to drive by yourself on the day of your pre-operative eye examination (due to retina exam which requires pupil dilatation can cause blurry vision for 4-5 hours).
  • Tell your doctor about all past and present medical and eye conditions.
  • Tell your doctor about all medications you are taking, including over-the-counter remedies, and any medications you may be allergic to


On the Day of the Procedure

 
  • You will be asked to arrive at least 60 minutes before the scheduled time of your surgery. 
  • Wear comfortable and clean clothes with a shirt that buttons up the front. 
  • Do not wear any perfume (their vapors can affect the efficiency of the laser beam). 
  • Do not apply any makeup, powder, foundation, after-shave, hair gel, cream or lotion. 
  • You may eat, drink and take your usual medications on the day of your surgery.
  • Arrange for transportation, or let the coordinators at the center assist you - it is not advisable to drive by yourself on the day of surgery.



After the Procedure

 

  • Immediately after surgery, your vision will probably be hazy or blurry, but clarity should improve by the very next morning.
  • Do not rub your eyes - it could dislodge the flap, requiring further treatment.
