TransPRK

ASLA/ TransPRK Surgery in Johannesburg

TransPRK (transepithelial photorefractive keratectomy) and ASLA (advanced surface laser ablation) are advanced versions of similar procedures such as LASEK, Epi-LASIK and PRK. Performed using the SCHWIND AMARIS 750S laser, TransPRK is a “no touch” or “pure laser” surface treatment that eliminates the need for contact between the eye and any instrument. This means that, in contrast to traditional PRK, the epithelium (the regenerative surface of the eye) is removed with a laser rather than an instrument. TransPRK is also more precise, so the treatment area is smaller, the procedure time is shorter, and there is less possibility of overcorrection.

TransPRK Procedure

First, the area around the eye is disinfected and then a speculum is inserted to gently hold the eye open and inhibit eye movements. The cornea is numbed with anesthetic eye drops. Dr. Guglielmetti will direct the laser to remove the top layer of the cornea. Next, the cool laser will precisely remove microscopic amounts of tissue to reshape the cornea. Some patients feel a bit of pressure as this process takes place.

Once the reshaping has been completed, a soft contact lens acts as a protective bandage on the eye to facilitate healing. Dr. Guglielmetti will prescribe antibiotic and anti-inflammatory eye drops to be used throughout the recovery period. The lens can usually be removed three days after surgery, which is a much faster healing process compared to manual PRK.

TransPRK Candidates

TranPRK/ASLA is often a great option for patients who are not candidates for traditional LASIK in Johannesburg. Dr. Guglielmetti performs TransPRK on patients who have extremely thin or irregularly shaped corneas. He regularly treats patients who have been told they cannot receive laser eye surgery because of these and various other conditions.

Recovery

Immediately after TransPRK/ASLA surgery, you will need to rest and avoid rubbing or irritating your eyes with soap, facial lotions, or cosmetics. You should avoid intense exercise for at least a week to prevent healing complications. The JHB staff will provide you with a comprehensive overview of how to care for your eyes after TranPRK/ASLA. Dr. Guglielmetti will see you for several post-operative appointments to assess your recovery.

As well as TransPRK, Dr. Guglielmetti performs glaucoma surgery in Johannesburg to prevent any loss of vision. Cataract surgery and traditional LASIK are also some of his specialties. With his abundant resources and experience, Dr. Guglielmetti is able to suggest the most effective treatments for each patient’s vision needs.
