According to Dr. Liao, Cia-Cing, some patients had inherently thinner corneas, after evaluation among various available measures of Laser Eye Surgery, for those who with insufficient corneal thickness or near threshold value, SMART TransPRK can be chosen. In the surgery, laser is performed on cornea’s outermost layer-epithelium to reserve effective thickness of corneal stroma as much as possible, increasing safety of the operation.
Wearing glasses may lead to foreign body sensation, some experienced troublesome care regimen in using contact lenses, lots of people chose Laser Eye Surgery to save some trouble but it may not be suitable for everyone, preoperative assessment is essential. The Director of Eye Center, Dr. Liao, Cia-Cing suggested, it is the most ideal for the case with inherent corneal thickness of more than 500 µm, because the too much thinner residual thickness after removal of the cornea may result in irregular deformation of the surface of the cornea, cornea bulges, and probably keratoconus for severer cases, or even with the risk requiring cornea transplant.
Worry about eye surgery? The least removal of cornea with the Zero-contact SMART TransPRK
The commonly used Lasik mostly cuts the cornea to produce corneal flaps, using a laser for diopter correction after opening; in another measure of SMILE laser, a small, lens-shaped bit of tissue is created deeply within the cornea for myopia correction. These two operations cause deeper damage to the cornea, affecting the health of corneal stroma deep inside.

Additionally, Dr. Liao indicates that because Excimer laser is used in the entire operation, any contact with patient’s cornea is not required during the procedure, relatively minimizing the infection risk or the deviation from physician’s operations performed. Moreover, without opening up the cornea to produce corneal flaps, SMART TransPRK completely avoids related risks caused in conventional operations involving corneal flaps,
Higher corneal stability in postoperative SMART TransPRK, most suitable for myopic population enjoying strenuous exercises.
Various measures of Laser Eye Surgery possess individual strengths and weaknesses, such as the shortest postoperative recovery in Lasik; on the other hand, the highest corneal stability is found from complete recovery of SMART TransPRK, without any worry about consequent deviation of corneal flaps resulted from foreign forces, solving also the astigmatism problem at one time, especially suitable for myopic population enjoying strenuous exercises.
As per Dr. Liao, conditions including foreign body sensation in the eye, mild pain, tearing or photophobia may occur during the first two or three days of the surgery, these uncomfortable conditions normally completely disappear by the third day in most patients. Immediately after the surgery completed, patient will be asked to wear a protective contact lens for protection of the wound to minimize infection risk, pain and discomfort, eye drops and oral analgesics may also be given to patient during the recovery for symptom relief.
In choosing Laser Eye Surgery, everybody has their own considerations, it is imperative to consult physician’s professional advices before surgery, assessing to choose the most suitable correction measure.
