Laser Vision Correction Procedures: The Difference
TransPRK (Laser Photorefractive Keratectomy) in Singapore
What is SafeSight TransPRK?
Safe Sight TransPRK is a vision correction procedure derived from epi-LASIK for patients who rely on glasses or contacts because of nearsightedness, farsightedness or astigmatism It is a safe, non-invasive and surface-based treatment method which does not require the eye surgeon to cut a corneal flap. Safe Sight TransPRK can eliminate some of the risks in the standard LASIK (cut, flap and zap) procedure such as flap-related medical complications.
Benefits of Safe Sight TransPRK
Quick, gentle procedure: The procedure takes only a few minutes per eye. It is touch-free, as no surgical instruments come in contact with the eye.
Short recovery: Patients wear a bandage contact lens for several days after surgery as the eye heals.
No risk of flap complications: Because no flap is created during surgery, there is no risk of it becoming dislodged or otherwise damaged during the recovery period.
Available to patients who do not qualify for traditional LASIK: The procedure is a safe option for individuals whose thin corneas or naturally dry eyes prevent them from having LASIK.
Great results: The visual outcomes are excellent and comparable to those of traditional LASIK.
How Does Safe Sight TransPRK Work?
Safe Sight TransPRK is an all laser, one-step no-touch laser vision correction procedure as compared to the conventional cut-and-flap LASIK. Unlike LASIK, it eliminates flap-related medical complications and dry eye problems.
We use the Schwind Amaris 1050RS excimer laser, which offers unparalleled safety, speed and precision. The Schwind Amaris 1050RS laser is equipped with a zero-latency eye tracker. It also has the ability to track all seven dimensions of eye movements, resulting in fast and accurate treatment.
First, the Schwind Amaris laser gently ablates the surface epithelium cells. (Patient looks ahead at a green blinking fixation light)
Second, the Schwind Amaris laser goes on to reshape the cornea curvature to correct the patient’s myopia in one seamless step. (Patient simply continues to fixate gaze on green blinking light)
Third, the doctor places a bandaged contact lens over the patient’s eye. Patient wears the contact lenses for about five days.
Fourth, the cornea’s epithelium layer regenerates itself in three to five days with the help of the high-oxygen content soft lens, which acts as an artificial flap. Contact lenses are then removed by the eye surgeon during the follow-up review.
Recovering from Safe Sight TransPRK
After a traditional LASIK procedure, the corneal flap created during the procedure is restored to its original position over the eye, where it heals itself. After a TransPRK procedure, there is no flap to heal. The surface (epithelial) cells of the cornea must regrow on their own in the days following surgery. A bandage contact lens is placed over the eye to promote healing and protect the eye as the cells regenerate. The contact lens is removed approximately five days after surgery.
Medication is prescribed to aid in the eye’s healing and prevent discomfort during recovery. Patients are asked to use the eyedrops for about six to 10 weeks after surgery. Follow-up visits are scheduled to check on the eye’s healing progress and assess visual recovery.
Who Is a Good Candidate for Safe Sight TransPRK?
Safe Sight TransPRK is appropriate for many individuals who do not qualify for traditional LASIK because of naturally thin corneas. Because no flap is created in the cornea during TransPRK, there is no risk of damaging or weakening a thin cornea.
Safe Sight TransPRK is also suitable for individuals whose dry eye problems prohibit them from qualifying for LASIK. The procedure does not cut or damage the nerves to the corneas, so there is minimal risk of dry eye symptoms after surgery.
Finally, Safe Sight TransPRK is a great option for individuals who work in a physically demanding job (e.g., professional athletes or first responders) and are at a heightened risk of eye trauma during the recovery period. These individuals are usually discouraged from having traditional LASIK because of the risk of dislodging a healing flap. The absence of a corneal flap with TransPRK makes it a good option for these groups of people.
